Answer 1

Change android:layout_gravity="start" to either android:layout_gravity="end" or android:layout_gravity="right" (using end will put the drawer on the left side of the screen for right-to-left configurations)

EDIT

It appears that the ActionBarDrawerToggle is looking for a drawer on the same side as the action bar Home icon (Gravity.START), which would be the left side for left-to-right layout directions. If you will always have the drawer on the right, you could do something like this:

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawer, R.drawable.ic_drawer, R.string.open_drawer, R.string.close_drawer) {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
                mDrawer.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawer.openDrawer(Gravity.RIGHT);
            }
        }
        return false;
    }
};

If the drawer will always be opposite the action bar Home icon, you could use Gravity.END instead.

Answer 2

I have the same problem since my app is Arabic and must begin from the right.

After testing all solutions here, I found that the best is:

• add this line in manifest : android:supportsRtl="true"
• in your activity add this code : getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
• in your listview don't use : android:layout_gravity="right" because if you use right you get the error in more Android versions like 4.0.4

The solution is the use of: android:layout_gravity="start", because in this case the listview follows the gravity of the page.

Answer 3

It is a bug in the home button click in ActionBar that shows itself in line:

if (mDrawerToggle.onOptionsItemSelected(item)) {
    return true;
}

remove the lines I mentioned, where you have method:

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
   if (mDrawerToggle.onOptionsItemSelected(item)) {
      return true;
   }
   //....
}

and replace it with:

@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    if (item != null && item.getItemId() == android.R.id.home) {
        if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
            mDrawerLayout.closeDrawer(Gravity.RIGHT);
        } else {
            mDrawerLayout.openDrawer(Gravity.RIGHT);
        }
        return true;
    }
    //...
}

Also do not forget to change the gravity of ListView to right: android:layout_gravity="right"
