Question

I have a problem with my Dialog Fragment. I wanted to use android:onClick attribute as in my opinion code is more clear then.

In my layout I have the following declarati

I would try a different approach which works fine for me:

1. implement an OnClickListener into your fragment:

   public class DialogNewDatabase extends DialogFragment implements OnClickListener`
   

2. have a button with an unique id in xml, which does NOT need android:clickable

3. override the method onClick() within your fragment and insert a reaction on your click:

   public void onClick(View v) {       
     switch (v.getId()) {
       case R.id.dialog_new_database_button_cancel:
           // your stuff here
           this.dismiss();
   
           break;          
       default:                
           break;
      }
   }   
   

4. import the necessary:

   import android.view.View.OnClickListener; 
   

5. start the onClickListener on the button:

   private Button bCancel = null;
   bCancel = (Button) findViewById(R.id.dialog_new_database_button_cancel);
   bCancel.setOnClickListener(this);
   // it is possible that you might need the refrence to the view.
   // replace 2nd line with (Button) getView().findViewById(...);
   

   This way you can handle even more clickable buttons in the same onClick-method. You just need to add more cases with the proper ids of your clickable widgets.
