By default the DrawerLayout is initially hidden from the view unless you put a code to open the Drawer
, by the time there is a sliding event triggered.
From the Navigation Drawer example, the contain content_frame
is used to dynamically display views inside the Drawer
using fragments.
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
From the Fragment
's onCreateView()
you can include a button somewhere that has OnClickListener
where in you put this code,
//For me a better way in avoiding a `null pointer` in getting the DrawerLayout
final DrawerLayout drawer = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
//Opens the Drawer
drawer.openDrawer(Your View, Usually a ListView);
}
return false;
});
You Can also use* to close the drawer.
drawer.closeDrawer(Your View, Usually a ListView);
