内部视图上的自定义listview onclicklistener

Question

Everything with my listview is fine, but now i neet to know, how to set an onClickListener to an view, defined in my list_row.xml. i just want the onclicklistener on the whole item, and on this one inner view. I attach a picture to demonstrate my problem, because it is so hard to describe >.< Picture (dropbox): https://www.dropbox.com/s/72xdxuwz47vl7s5/problem.png

I need a function that is called when clicking into the view [my Problem] indicates. its an ImageView filled with an image.

Answer 1

To set an OnClickListener in each row simply extend your current Adapter and override the getView() method. In there you can define specific listeners as you normally would.

This is discussed in great detail in this Google Talk by Romain Guy.

Answer 2

Here's something I've done before that seems pretty similar to what you want to accomplish.

First, you declare an onItemClickListener for your ListView . This will handle standard list item taps (that is, taps inside a list item but outside the inner view region that you're concerned about). You can do this in a variety of places in your code, but onCreate() is a common one.

Example:

mListView.setOnItemClickListener( new OnItemClickListener() {
  @Override
  public void onItemClick( AdapterView<?> parent, View view, int position, long id ) {
    // Handle standard list item tap
    // ...
  }
} );

Then, you can just declare whatever onClickListener s you need for your inner view(s) inside your adapter's getView() method to handle click/tap events on your inner view.

Example:

@Override
public View getView( int position, View convertView, ViewGroup parent ) {
  LinearLayout itemView;

  // Inflate layout XML, etc.
  // ...

  // Find subviews in layout
  ImageView innerView = (ImageView) itemView.findViewById( R.id.myInnerViewId );

  // ...

  // Set up onClickListener for inner view
  innerView.setOnClickListener( new OnClickListener() {
    @Override
    public void onClick( View v ) {
      // Handle inner view tap
      // ...
    }
  } );

  // ...
}
