Code snippet for changing the application box
I am writing an application Android
using Navigation Drawer
. I want to change the current one fragment
on button click.
public void btnClick(){
...
changeFragment();
...
}
private void changeFragment() {
Fragment home = new Home();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.navigation_drawer, home);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.addToBackStack(null);
ft.commit();
}
I am getting the following error in LogCat
:
FATAL EXCEPTION: main
java.lang.UnsupportedOpetaionException: addView(View) is not supported in AdapterView
My Home
fragment is loaded and displayed at the beginning, and after navigating to another fragment and clicking a button, I want to automatically return to the fragment Home
.
How can i do this?

If I understand you are trying to change the fragment below the navigation box, not the navigation box itself (which is much more complicated).
In this line:
ft.replace(R.id.navigation_drawer, home);
You have to replace R.id.navigation_drawer for FragmentLayout, which should be in your activitylayout.xml file.
Something like:
ft.replace(R.id.fragment_layout, home);
