嗯，我想，你应该在覆盖onClick

的同时实施Button getChildView()

public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
                   View convertView, ViewGroup parent) {
        LinearLayout v = (LinearLayout) LayoutInflater.from(FindFilesByType.this).inflate(R.layout.row, null) ; //we assume your layout file name is row.xml
        Button btnPlay=(Button)v.findViewById(R.id.Play);
        Button btnDelete=(Button)v.findViewById(R.id.Delete);
        Button btnEmail=(Button)v.findViewById(R.id.Email);
        btnPlay.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Toast.makeText(FindFilesByType.this, "u clicked play btn", Toast.LENGTH_LONG).show();               
            }
        }); 
        return v;


}
