Android Studio调试器不会在onItemClick（）内的断点处停止？

Question

  

看到Toast消息，但断点不会停止执行。
  以下方法在NewsListActivity的onCreate里面。

// click event for list item
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            int myPostion = position;
            long myID = id;
            Toast.makeText(getApplicationContext(), String.valueOf(position),Toast.LENGTH_SHORT).show();
            Intent intent = new Intent(NewsListActivity.this,NewsDetailActivity.class);
            startActivity(intent);
        }
    });
