This is my code:
public class DeleteRewardsFragment extends Fragment{
private Context context;
private FragmentsActivity activity;
private ListView listView;
private View myFragmentView;
private DeleteRewardsAdapter adapter;
private String[] values;
@SuppressLint("ResourceAsColor")
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
myFragmentView = inflater.inflate(R.layout.listview, container, false);
listView = (ListView) myFragmentView.findViewById(android.R.id.list);
activity = (FragmentsActivity) getActivity();
context = activity.getApplicationContext();
values = new String[4];
adapter = new DeleteRewardsAdapter(context, values);
listView.setAdapter(adapter);
listView.setOnItemClickListener(deleteEvent);
return myFragmentView;
}
private OnItemClickListener deleteEvent = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
alertDialog .setTitle("Jetzt löschen?");
alertDialog .setMessage("Die in deisem Store gesammelten stampss gehen debei verloren!")
.setCancelable(false)
.setPositiveButton("Abbrechen", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
values = new String[values.length-1];
adapter = new DeleteRewardsAdapter(context, values);
listView.setAdapter(adapter);
}
})
.setNegativeButton("Löschen", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = alertDialog.create();
dialog.show();
}
};
}
Can someone to help me?
To add AlertDialog
to your Activity
or Fragment
you have to use your Activity
's instance, not your application's which you are doing in your code. Create your AlertDialog
like this :
AlertDialog.Builder alertDialog = new AlertDialog.Builder(getActivity());
And that should do the trick for you! : )
