Issues In Implementing Gridview Within A Fragment

I am working on a small application which contains Activity with NavigationDrawer, and i have placed a fragment on that activity using FragmentManager and FragmentTrancation. Probl

Solution 1:

You're not respecting the Activity lifecycle. When you do this

FragmentManagerFM= getFragmentManager();
FragmentTransactionTrans= FM.beginTransaction();

before the method onCreate being called, you don't have the Activity properly created.

Move that code to the onCreate method:

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stubsuper.onCreate(savedInstanceState);
    setContentView(R.layout.navigation_drawer);
    AddAppsAapps=newAddApps();
    drawerlayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    LVdrawer = (ListView) findViewById(R.id.left_drawer);
    LVdrawer.setAdapter(newCustomAdapter(this, 1));

    FragmentManagerFM= getFragmentManager();
    FragmentTransactionTrans= FM.beginTransaction();

    Trans.add(R.id.content_frame, Aapps, "AddAppsF");
    Trans.addToBackStack("AddApps");
    Trans.commit();
}
