sliding drawer appear in all activities

I am developing an application that contains many activities and i created my own menu (i don't want to use the built in menu button) with the Sliding Drawer as the sliding drawer is at the bottom of the screen and contains my menu buttons

what i need is to make that sliding drawer to appear in all my activities

i tried to create an activity and set it's content view to the xml file that includes the drawer and then extends that activity in all other activities but this solution doesn't work

so any suggestions ?

Solution 1:

Extending is the right way. Just override setContentView in the right way. Here's the working example, but instead of drawer, I use a created a custom tabbar:

Define a layout with your drawer like this:

this is act_layout.xml

<LinearLayout
  ...
  android:orientation="vertical"
>
  <YourDrawer
    ...
  />
  <FrameLayout
    android:id="@+id/act_content"
    ...
  >
    // Here will be all activity content placed
  </FrameLayout>
</LinearLayout>

This will be your base layout to contain all other layouts in the act_content frame. Next, create a base activity class, and do the following:

public abstract class DrawerActivity extends Activity {

    protected LinearLayout fullLayout;
    protected FrameLayout actContent;

    @Override
    public void setContentView(final int layoutResID) {
        // Your base layout here
        fullLayout= (LinearLayout) getLayoutInflater().inflate(R.layout.act_layout, null); 
        actContent= (FrameLayout) fullLayout.findViewById(R.id.act_content);

        // Setting the content of layout your provided to the act_content frame
        getLayoutInflater().inflate(layoutResID, actContent, true); 
        super.setContentView(fullLayout);

        // here you can get your drawer buttons and define how they 
        // should behave and what must they do, so you won't be 
        // needing to repeat it in every activity class
    }
}

What we do, is basically intercept all calls to setContentView(int resId), inflate our layout for drawer from xml, inflate our layout for activity (by reId provided in method call), combine them as we need, and set as the contentView of the activity.

EDIT: After you've created the stuff above, just proceed to write an app as usual, create layouts (without any mention of a drawer) create activities, but instead of extending simple activity, extend DrawerActivity, like so:

public abstract class SomeActivity extends DrawerActivity {

    protected void onCreate(Bundle bundle) {
        setContentView(R.layout.some_layout);
    }
}

What happens, is that setContentView(R.layout.some_layout) is intercepted. Your DrawerActivity loads the layout you provided from xml, loads a standart layout for your drawer, combines them and then sets it as contentView for the activity.

Solution 2:

Finally after 3 years, here's the complete solution to this important question for whom may have not been completely guided by Mr. Orlov's answer.

His method for making a hierarchy view was completely OK but there was some small mistakes that may mislead beginner developers.

1. As Gabe also mentioned, you can get rid of abstract in declaration.
2. There's no need to wrap both child with a FrameLayout. The parent could be anything RelativeLayout, LinearLayout, etc. But the most important part is that you must declare the FrameLayout before the Slider.

So the 100% working soloution would be like this :

activity_drawer.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<FrameLayout
    android:id="@+id/drawer_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<YourDrawer
    android:id="@+id/drawer_drawer"
    android:layout_width="match_parent"
    android:layout_height="fill_parent" >

</YourDrawer>

</RelativeLayout>

DrawerActivity.java

public class DrawerActivity extends Activity {

protected RelativeLayout fullLayout;
protected FrameLayout frameLayout;

@Override
public void setContentView(int layoutResID) {

    fullLayout = (RelativeLayout) getLayoutInflater().inflate(R.layout.activity_drawer, null);
    frameLayout = (FrameLayout) fullLayout.findViewById(R.id.drawer_frame);

    getLayoutInflater().inflate(layoutResID, frameLayout, true);

    super.setContentView(fullLayout);

    //Your drawer content...

}

}

MainActivity.java

public class MainActivity extends DrawerActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

}

}

Don't forget to declare DrawerActivity in manifest.

Hope it helped.

I know this is two years late but for those who would like an answer here it is. Mr Orlov had an appropriate response, just a few adjustments needed.

• delete the abstract after public. (this is what causes an error)
• wrap BOTH your sliding drawer and FrameLayout with another FrameLayout and set the width and height to match_parent. (This allows BOTH layouts to appear).

ALSO: If you want your sliding drawer to appear on top of your layout (duh!) then place the frameLayout that is after the slidingDrawer before the slidingDrawer.
