Hide TabLayout on Scroll of Content instead of ToolBar
I want to hide TabLayout on scrolling my content. Currently I searched the net but I found samples which hide the Toolbar, but I want to hide TabLayout. So please help me. I tried below code.
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/id_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="@+id/id_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"/>
<android.support.design.widget.TabLayout
android:id="@+id/id_tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
style="@style/MyCustomTabLayout"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/id_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Here is the example applications: https://play.google.com/store/apps/details?id=com.contextlogic.wish https://play.google.com/store/apps/details?id=co.vine.android
Try this approach. The main idea is to move Toolbar outside the CoordinatorLayout and wrap this view structure with other container layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/id_toolbar_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="@+id/id_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|exitUntilCollapsed" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/id_toolbar_container">
<android.support.design.widget.AppBarLayout
android:id="@+id/id_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="@+id/id_tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/id_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
</RelativeLayout>
While doing animation on scroll, CoordinatorLayout starts searching all the children views of AppBarLayout in a linear manner and it stops animating layouts once it finds a layout with non-scrolling tag.
Exp1:
<CoordinatorLayout>
<AppBarLayout>
<layout1 with scrollFlag = "scroll|enterAlways">
<layout2 with no scrollFlag>
</AppBarLayout>
</CoordinatorLayout>
Only layout1 will have animation
Exp2:
<CoordinatorLayout>
<AppBarLayout>
<layout1 with no scrollFlag>
<layout2 with scrollFlag = "scroll|enterAlways">
</AppBarLayout>
</CoordinatorLayout>
None of them will have animation
Exp3: If none of them have scrollFlag, none of them will have animation
Exp4: If both of them have scrollFlag, both of them will have animation
In your case, you'll need to keep toolbar outside the coordinator layout and add tablayout as a child of AppBarLayout with scrollFlags = "scroll|enterAlway"
