Listview嵌套ListView 及包含button onItemClic失效问题

1，在主Listview Item XML中最顶层这里我用的是LinearLayout 设置android:descendantFocusability="blocksDescendants"

并设置主Listview android:focusable="false"

子ListView事件和button事件

//listview事件

viewHolder.listView.setOnItemClickListener(new listv_Goods());

private class listv_Goods implements OnItemClickListener{

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
Map<String, String> item = (Map<String, String>) parent.getItemAtPosition(position);
Toast.makeText(context, item.get("name"),Toast.LENGTH_LONG).show();
} 
}

button

viewHolder.btn_Track.setOnClickListener(new btnOnClick(position));

private class btnOnClick implements OnClickListener{ 
int position ; 
public btnOnClick(int pos)
{
position=pos;
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v.getId()==R.id.btn_Track)
{
Toast.makeText(context, listMaps.get(position).get("orderId"),Toast.LENGTH_LONG).show();
}
} 
}
