android - 如何在 OnContextItemSelected 事件中获取 View ？

Question

在 public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo} 事件中，

我想我可以通过 arg View v 使用以下命令知道哪个控件启动 onCreateContextMenu 事件，对吗？
ImageView imageview=(ImageView)v

但是在 public boolean onContextItemSelected(MenuItem item) 中，我找不到相同的 arg，我该怎么办？谢谢!

Answer 1

您可以像这样使用 ContextMenu.ContextMenuInfo:

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    int index = info.position;
}

您还可以获得显示菜单的确切 View :

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
    int index = info.position;
    View view = info.targetView;
}
