dialogfragment 使用contextMenu，点击菜单项没反应

经过测试，点击菜单项时onContextItemSelected(MenuItem item)没有执行到，不清楚是不是事件被activity拦截了，在stackoverflow找到解决方法
如下：

@Override
public void onCreateContextMenu(ContextMenu menu, View view, ContextMenuInfo menuInfo) {
// Creation/inflate menu here

OnMenuItemClickListener listener = new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
onContextItemSelected(item);
return true;
}
};

for (int i = 0, n = menu.size(); i < n; i++)
menu.getItem(i).setOnMenuItemClickListener(listener);
}
