i'm developing an application where I have tabs and fragments within each tab. I got it to work where it shows my listview on launch and when I click a name in the list its goes to the next fragment, but when I hit the back button it doesn't go back to the listview I just get a blank screen. I'm sure it's a simple answer and I have posted some code snippets, if more is needed please let me know. Thank you for your help.
public class HomeStackActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragmentstackctivity);
// add initial fragment, do not add to back stack, no transition animation
addFragment(new MyCommentActivity(), false, FragmentTransaction.TRANSIT_NONE);
}
void addFragment(Fragment fragment, boolean addToBackStack, int transition) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.fragment1, fragment);
ft.setTransition(transition);
if (addToBackStack)
ft.addToBackStack(null);
ft.commit();
}
public void onBackPressed() {
FragmentManager manager = getSupportFragmentManager();
if (manager.getBackStackEntryCount() > 0)
getSupportFragmentManager().popBackStack();
else
finish();
}
}
public class nameOnClickListener implements OnClickListener{
private int position;
public nameOnClickListener(int position){
this.position=position;
}
@Override
public void onClick(View v) {
HashMap<String, String> update = new HashMap<String, String>();
update = commentList.get(position);
Log.d("Testing Click", update.get(MyCommentActivity.KEY_UID));
SharedPreferences sp = PreferenceManager
.getDefaultSharedPreferences(getActivity());
SharedPreferences.Editor edit = sp.edit();
edit.putString("profile_id", update.get(MyCommentActivity.KEY_UID));
edit.putString("profile_type", update.get(MyCommentActivity.KEY_TYPE));
edit.commit();
addFragment(new UserProfileActivity(), true, FragmentTransaction.TRANS
change:
ft.replace(R.id.fragment1, fragment);
to:
ft.add(R.id.fragment1, fragment);
