Android TabLayout Android Design
I'm trying to get the new TabLayout in the android design library working.
I'm following this post:
http://android-developers.blogspot.com/2015/05/android-design-support-library.html
and the documentation:
http://developer.android.com/reference/android/support/design/widget/TabLayout.html
And have come up with the following code in my activity but the tablayout isn't showing up when I run the activity.
I tried adding in the activity layout file, but it says it can't find that xml tag.
public class TabActivity extends BaseActivity {
SectionPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab);
LinearLayout v = (LinearLayout)findViewById(R.id.tabContainer);
TabLayout tabLayout = new TabLayout(this);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, 50));
v.addView(tabLayout);
mSectionsPagerAdapter = new SectionPagerAdapter(getFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
tabLayout.setupWithViewPager(mViewPager);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
}
public class SectionPagerAdapter extends FragmentPagerAdapter {
private String TAG = "SectionPagerAdapter";
public SectionPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position)
{
return new Fragment();
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return "test";
case 1:
return "test";
case 2:
}
return null;
}
}
}
Added the following to my gradle file
compile 'com.android.support:design:22.2.0'
Solution 1:
I've just managed to setup new TabLayout, so here are the quick steps to do this (ノ◕ヮ◕)ノ*:・゚✧
-
Add dependencies inside your build.gradle file:
dependencies { compile 'com.android.support:design:23.1.1' }
-
Add TabLayout inside your layout
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/colorPrimary"/> <android.support.design.widget.TabLayout android:id="@+id/tab_layout" android:layout_width="match_parent" android:layout_height="wrap_content"/> <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent"/> </LinearLayout>
-
Setup your Activity like this:
import android.os.Bundle; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; public class TabLayoutActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_pull_to_refresh); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout); ViewPager viewPager = (ViewPager) findViewById(R.id.pager); if (toolbar != null) { setSupportActionBar(toolbar); } viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager())); tabLayout.setupWithViewPager(viewPager); } public class SectionPagerAdapter extends FragmentPagerAdapter { public SectionPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { switch (position) { case 0: return new FirstTabFragment(); case 1: default: return new SecondTabFragment(); } } @Override public int getCount() { return 2; } @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "First Tab"; case 1: default: return "Second Tab"; } } } }
Solution 2:
I had to collect information from various sources to put together a functioning TabLayout. The following is presented as a complete use case that can be modified as needed.
Make sure the module build.gradle
file contains a dependency on com.android.support:design
.
dependencies {
compile 'com.android.support:design:23.1.1'
}
In my case, I am creating an About activity in the application with a TabLayout. I added the following section to AndroidMainifest.xml
. Setting the parentActivityName allows the home arrow to take the user back to the main activity.
<!-- android:configChanges="orientation|screenSize" makes the activity not reload when the orientation changes. -->
<activity
android:name=".AboutActivity"
android:label="@string/about_app"
android:theme="@style/MyApp.About"
android:parentActivityName=".MainActivity"
android:configChanges="orientation|screenSize" >
<!-- android.support.PARENT_ACTIVITY is necessary for API <= 15. -->
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
styles.xml
contains the following entries. This app has a white AppBar for the main activity and a blue AppBar for the About activity. We need to set colorPrimaryDark
for the About activity so that the status bar above the AppBar is blue.
<style name="MyApp" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorAccent">@color/blue</item>
</style>
<style name="MyApp.About" />
<!-- ThemeOverlay.AppCompat.Dark.ActionBar" makes the text and the icons in the AppBar white. -->
<style name="MyApp.DarkAppBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="MyApp.AppBarOverlay" parent="ThemeOverlay.AppCompat.ActionBar" />
<style name="MyApp.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
There is also a styles.xml (v19)
. It is located at src/main/res/values-v19/styles.xml
. This file is only applied if the API of the device is >= 19.
<!-- android:windowTranslucentStatus requires API >= 19. It makes the system status bar transparent.
When it is specified the root layout should include android:fitsSystemWindows="true".
colorPrimaryDark goes behind the status bar, which is then darkened by the overlay. -->
<style name="MyApp.About">
<item name="android:windowTranslucentStatus">true</item>
<item name="colorPrimaryDark">@color/blue</item>
</style>
AboutActivity.java
contains the following code. In my case I have a fixed number of tabs (7) so I could remove all the code dealing with dynamic tabs.
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class AboutActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about_coordinatorlayout);
// We need to use the SupportActionBar from android.support.v7.app.ActionBar until the minimum API is >= 21.
Toolbar supportAppBar = (Toolbar) findViewById(R.id.about_toolbar);
setSupportActionBar(supportAppBar);
// Display the home arrow on supportAppBar.
final ActionBar appBar = getSupportActionBar();
assert appBar != null;// This assert removes the incorrect warning in Android Studio on the following line that appBar might be null.
appBar.setDisplayHomeAsUpEnabled(true);
// Setup the ViewPager.
ViewPager aboutViewPager = (ViewPager) findViewById(R.id.about_viewpager);
assert aboutViewPager != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutViewPager might be null.
aboutViewPager.setAdapter(new aboutPagerAdapter(getSupportFragmentManager()));
// Setup the TabLayout and connect it to the ViewPager.
TabLayout aboutTabLayout = (TabLayout) findViewById(R.id.about_tablayout);
assert aboutTabLayout != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutTabLayout might be null.
aboutTabLayout.setupWithViewPager(aboutViewPager);
}
public class aboutPagerAdapter extends FragmentPagerAdapter {
public aboutPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
// Get the count of the number of tabs.
public int getCount() {
return 7;
}
@Override
// Get the name of each tab. Tab numbers start at 0.
public CharSequence getPageTitle(int tab) {
switch (tab) {
case 0:
return getString(R.string.version);
case 1:
return getString(R.string.permissions);
case 2:
return getString(R.string.privacy_policy);
case 3:
return getString(R.string.changelog);
case 4:
return getString(R.string.license);
case 5:
return getString(R.string.contributors);
case 6:

default:
return "";
}
}
@Override
// Setup each tab.
public Fragment getItem(int tab) {
return AboutTabFragment.createTab(tab);
}
}
}
AboutTabFragment.java
is used to populate each tab. In my case, the first tab has a LinearLayout
inside of a ScrollView
and all the others have a WebView
as the root layout.
import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;

public class AboutTabFragment extends Fragment {

// AboutTabFragment.createTab stores the tab number in the bundle arguments so it can be referenced from onCreate().
public static AboutTabFragment createTab(int tab) {
Bundle thisTabArguments = new Bundle();
thisTabArguments.putInt("Tab", tab);
AboutTabFragment thisTab = new AboutTabFragment();
thisTab.setArguments(thisTabArguments);
return thisTab;
}
@Override
public void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Store the tab number in tabNumber.
tabNumber = getArguments().getInt("Tab");
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View tabLayout;
// Load the about tab layout. Tab numbers start at 0.
if (tabNumber == 0) {
// Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
// The fragment will take care of attaching the root automatically.
tabLayout = inflater.inflate(R.layout.about_tab_version, container, false);
} else { // load a WebView for all the other tabs. Tab numbers start at 0.
// Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
// The fragment will take care of attaching the root automatically.
tabLayout = inflater.inflate(R.layout.about_tab_webview, container, false);
WebView tabWebView = (WebView) tabLayout;
switch (tabNumber) {
case 1:
tabWebView.loadUrl("file:///android_asset/about_permissions.html");
break;
case 2:
tabWebView.loadUrl("file:///android_asset/about_privacy_policy.html");
break;
case 3:
tabWebView.loadUrl("file:///android_asset/about_changelog.html");
break;
case 4:
tabWebView.loadUrl("file:///android_asset/about_license.html");
break;
case 5:
tabWebView.loadUrl("file:///android_asset/about_contributors.html");
break;
case 6:
tabWebView.loadUrl("file:///android_asset/about_links.html");
break;
default:
break;
}
}
return tabLayout;
}
}
about_coordinatorlayout.xml
is as follows:

Solution 3:
I am facing some issue with menu change when fragment changes in ViewPager. I ended up implemented below code.
DashboardFragment
public class DashboardFragment extends BaseFragment {
private Context mContext;
private TabLayout mTabLayout;
private ViewPager mViewPager;
private DashboardPagerAdapter mAdapter;
private OnModuleChangeListener onModuleChangeListener;
private NavDashBoardActivity activityInstance;
public void setOnModuleChangeListener(OnModuleChangeListener onModuleChangeListener) {
this.onModuleChangeListener = onModuleChangeListener;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.dashboard_fragment, container, false);
}
//pass -1 if you want to get it via pager
public Fragment getFragmentFromViewpager(int position) {
if (position == -1)
position = mViewPager.getCurrentItem();
return ((Fragment) (mAdapter.instantiateItem(mViewPager, position)));
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mContext = getActivity();
activityInstance = (NavDashBoardActivity) getActivity();
mTabLayout = (TabLayout) view.findViewById(R.id.tab_layout);
mViewPager = (ViewPager) view.findViewById(R.id.view_pager);
final List<EnumUtils.Module> moduleToShow = getModuleToShowList();
mViewPager.setOffscreenPageLimit(moduleToShow.size());
for(EnumUtils.Module module :moduleToShow)
mTabLayout.addTab(mTabLayout.newTab().setText(EnumUtils.Module.getTabText(module)));
updateTabPagerAndMenu(0 , moduleToShow);
mAdapter = new DashboardPagerAdapter(getFragmentManager(),moduleToShow);
mViewPager.setOffscreenPageLimit(mAdapter.getCount());
mViewPager.setAdapter(mAdapter);
mTabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(final TabLayout.Tab tab) {
mViewPager.post(new Runnable() {
@Override
public void run() {
mViewPager.setCurrentItem(tab.getPosition());
}
});
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
//added to redraw menu on scroll
}
@Override
public void onPageSelected(int position) {
updateTabPagerAndMenu(position , moduleToShow);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
//also validate other checks and this method should be in SharedPrefs...
public static List<EnumUtils.Module> getModuleToShowList(){
List<EnumUtils.Module> moduleToShow = new ArrayList<>();
moduleToShow.add(EnumUtils.Module.HOME);
moduleToShow.add(EnumUtils.Module.ABOUT);
return moduleToShow;
}
public void setCurrentTab(final int position){
if(mViewPager != null){
mViewPager.postDelayed(new Runnable() {
@Override
public void run() {
mViewPager.setCurrentItem(position);
}
},100);
}
}
private Fragment getCurrentFragment(){
return mAdapter.getCurrentFragment();
}
private void updateTabPagerAndMenu(int position , List<EnumUtils.Module> moduleToShow){
//it helps to change menu on scroll
//http://stackoverflow.com/a/27984263/3496570
//No effect after changing below statement
ActivityCompat.invalidateOptionsMenu(getActivity());
if(mTabLayout != null)
mTabLayout.getTabAt(position).select();
if(onModuleChangeListener != null){
if(activityInstance != null){
activityInstance.updateStatusBarColor(
EnumUtils.Module.getStatusBarColor(moduleToShow.get(position)));
}
onModuleChangeListener.onModuleChanged(moduleToShow.get(position));
mTabLayout.setSelectedTabIndicatorColor(EnumUtils.Module.getModuleColor(moduleToShow.get(position)));
mTabLayout.setTabTextColors(ContextCompat.getColor(mContext,android.R.color.black)
, EnumUtils.Module.getModuleColor(moduleToShow.get(position)));
}
}
}
dashboardfragment.xml
<?xml version="1.0" encoding="utf-8"?>

android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</LinearLayout>
DashboardPagerAdapter
public class DashboardPagerAdapter extends FragmentPagerAdapter {
private List<EnumUtils.Module> moduleList;
private Fragment mCurrentFragment = null;
public DashboardPagerAdapter(FragmentManager fm, List<EnumUtils.Module> moduleList){
super(fm);
this.moduleList = moduleList;
}
@Override
public Fragment getItem(int position) {
return EnumUtils.Module.getDashboardFragment(moduleList.get(position));
}
@Override
public int getCount() {
return moduleList.size();
}
@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
if (getCurrentFragment() != object) {
mCurrentFragment = ((Fragment) object);
}
super.setPrimaryItem(container, position, object);
}
public Fragment getCurrentFragment() {
return mCurrentFragment;
}
public int getModulePosition(EnumUtils.Module moduleName){
for(int x = 0 ; x < moduleList.size() ; x++){
if(moduleList.get(x).equals(moduleName))
return x;
}
return -1;
}
}
And in each page of Fragment setHasOptionMenu(true)
in onCreate and implement onCreateOptionMenu
. then it will work properly.

public void onPostCreate(@Nullable Bundle savedInstanceState, @Nullable PersistableBundle persistentState) {
super.onPostCreate(savedInstanceState, persistentState);
// Sync the toggle state after onRestoreInstanceState has occurred.
toggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
toggle.onConfigurationChanged(newConfig);
}
}
Solution 4:
I try to solve here is my code.
first add dependency in build.gradle(app).
dependencies {
compile 'com.android.support:design:23.1.1'
}
Create PagerAdapter.class
public class PagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public PagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
Log.i("PosTabItem",""+position);
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
Log.i("PosTab",""+position);
return mFragmentTitleList.get(position);
}
}
create activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/toolbar"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="@id/tab_layout" />
</RelativeLayout>
create MainActivity.class
public class MainActivity extends AppCompatActivity {
Pager pager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
pager = new Pager(getSupportFragmentManager());
pager.addFragment(new FragmentOne(), "One");
viewPager.setAdapter(pager);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setSmoothScrollingEnabled(true);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
}
and finally create fragment to add in viewpager
crate fragment_one.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="Location"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Create FragmentOne.class
public class FragmentOne extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_one, container,false);
return view;
}
}
