title: Selector is applying change to all views instead of clicked view
body: <p>I'm working on adding an onClick highlight to a view in a drag and drop grid in Android. The project is on <a href="https://github.com/lkorth/PagedDragDropGrid" rel="nofollow">GitHub</a> (the dev branch contains the code that is using the selector).</p>
  
  <p>The problem I am having is in the adapter when I set the onClick selector as a view's background, when I click a view, instead of changing the background for just that view the selector changes the backgrounds for all the views.</p>
  
  <p>I'm pretty sure this is a result of how the clicks are being handled in onTouch in the ViewGroup (below). I'm not sure if I should I be returning true/false differently or triggering the onClick listener differently to prevent all of the views from being highlighted.</p>
  
  <p>Any ideas/help is appreciated, thanks.</p>
  
  <pre><code>@Override
  public boolean onTouch(View v, MotionEvent event) {
      int action = event.getAction();
      switch (action &amp; MotionEvent.ACTION_MASK) {
      case MotionEvent.ACTION_DOWN:
          touchDown(event);
          break;
      case MotionEvent.ACTION_MOVE:
          touchMove(event);
          break;
      case MotionEvent.ACTION_UP:
          touchUp(event);
          break;
      }
      if (aViewIsDragged())
          return true;
      return false;
  }
  
  private void touchUp(MotionEvent event) {
      if(dragged == -1) {
          if(onClickListener != null) {
              View clickedView = getChildAt(getTargetAtCoor((int) event.getX(), (int) event.getY()));
              if(clickedView != null)
                  onClickListener.onClick(clickedView);
          }
      } else {
          manageChildrenReordering();
          hideDeleteView();
          cancelEdgeTimer();
  
          movingView = false;
          dragged = -1;
          lastTarget = -1;
          container.enableScroll();
          cancelAnimations();
      }
  }

  <p>EDIT: After looking at the ViewGroup documentation <a href="http://developer.android.com/reference/android/view/ViewGroup.html#attr_android%3aaddStatesFromChildren" rel="nofollow">android:addStatesFromChildren</a> sounds like what I am looking for, but it doesn't seem to have any effect.</p>
  
  <blockquote>
    <p>android:addStatesFromChildren</p>
    
    <p>Sets whether this ViewGroup's drawable states also include its
    children's drawable states. This is used, for example, to make a group
    appear to be focused when its child EditText or button is focused.</p>
    
    <p>Must be a boolean value, either "true" or "false".</p>
    
    <p>This may also be a reference to a resource (in the form
    "@[package:]type:name") or theme attribute (in the form
    "?[package:][type:]name") containing a value of this type.</p>
    
    <p>This corresponds to the global attribute resource symbol
    addStatesFromChildren.</p>

  <p><strong>UPDATE</strong></p>
  
  <p>I have found a way to solve this. The pull request is <a href="https://github.com/mrKlar/PagedDragDropGrid/pull/12" rel="nofollow">here</a></p>
