onBindDialogView not called - Why?

Question

I am trying to implement a subclass of ListPreference and while its constructor is being called (upon displaying it), its overriden onBindDialogView isn't.

  public MyListPreference(Context context, AttributeSet attrs) {
    super(context, attrs);
    // TODO Auto-generated constructor stub
    Log.v(TAG, "MyListPreference constructed.");
  }


  @Override
  protected void onBindDialogView(View view) {
    super.onBindDialogView(view);
    Log.v(TAG, "onBindDialogView called");    
  }

Why is this happening? What am I missing?

Update: I planted a log message in onCreateDialogView() and it is being called, too.

It is only onBindDialogView() that is not being called.

Why? What are the conditions for this callback to be invoked?

@shoerat I am trying to [setOnTouchListener() on a ListPreference](http://stackoverflow.com/q/17192066). — scatmoi, Jun 27 '13 at 01:10

What does your onCreateDialogView() return? onBindDialogView() is called only if you return a non-null custom view from in there. Also, onBindDialogView() is only called when you actually show the preference. Ref: Source code of DialogPreference. In particular, see showDialog() method

If you just return the super implementation from your onCreateDialogView(), I suspect it returns null.

My `onCreateDialogView()` returns what its `super.onCreateDialogView()` returns: **null**. How do I make it return non-null without changing the original ListPreference view/layout? I don't really want to change anything in the view/layout. All I really want is get a handle/reference to the original ListPreference **view**. Is this at all possible? If so, how? +1 & thanks for now. – scatmoi Jun 27 '13 at 03:40
There doesn't seem to be a public API to get a handle to the `ListView` that is housed within a `ListPreference`. You do have a `DialogPreference#getDialog()` - which you can cast to `AlertDialog()`, and from there you can do a `getListView()` but this depends on a lot of implementation details and I wouldn't recommend it. I'd rather suggest you to create a custom `Preference` where you have full control over the content view. – curioustechizen Jun 27 '13 at 05:42
Actually, see [this comment](http://stackoverflow.com/questions/17181083/how-to-attach-gesturedetector-to-a-listpreference#comment25182806_17351742), but you answered my question so well, so accepting + bounty. – scatmoi Jun 28 '13 at 00:21
How do you get hold of all of the dialog, and set the direction of it (for example, in order to support it being RTL ) ? – android developer May 25 '14 at 21:59
