如何在OnContextItemSelected事件中获取View？

Question

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

我想我可以通过arg View v使用以下内容知道哪个控件启动onCreateContextMenu事件，对吧？ 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视图：

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

Answer 2

您可以使用

View v2;
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);
    v2=v;
      getMenuInflater().inflate(R.menu.cnt_menu, menu);
  //  }
  }
