Question

I’m having a problem displaying an AlertDialog from within the onOptionsItemSelected method. That is, I want the user to press the delete options button and then confirm the deletion before clearing the item from the db. If I run my current code my program crash. Hope someone can help. Much appreciated 🙂

Here’s a code snippet of what I have

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
      getMenuInflater().inflate(R.menu.detailsmenu, menu);
      return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
      // Handle item selection
      switch(item.getItemId()) {
      case R.id.rename:
        openRenameDialog();
        return true;
      case R.id.delete:         
        openDeleteDialog();
        return true;
      default:
        return super.onOptionsItemSelected(item);   
      }
    }

    private void openDeleteDialog() {
      AlertDialog.Builder alert = new AlertDialog.Builder(this);
      alert.setTitle(R.string.deleteTitle);
      alert.setMessage(R.string.deleteMessage);

      alert.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
          // todo       
        }
      });

      alert.setNegativeButton("No", new DialogInterface.OnClickListener() {
         public void onClick(DialogInterface dialog, int whichButton) { 
            dialog.cancel();
         }
      });

    alert.show();
}

Logcat output:

Answer 1

Make sure you have deleteTitle and deleteMessage string in the xml.
Also try using

AlertDialog.Builder alert = new AlertDialog.Builder(getApplicationContext());
