as per my above comment可以使用Popup Menu
Android Popup Menu displays the menu below the anchor text if space is available otherwise above the anchor text. It disappears if you click outside the popup menu.
试试这个创建菜单文件
文件：poupup_menu.xml
android:id="@+id/one"
android:title="One"/>
android:id="@+id/two"
android:title="Two"/>
android:id="@+id/three"
android:title="Three"/>
比使用像这样的创建弹出菜单
holder.img_chatroom_menu.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(MainActivity.this, button1);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(MainActivity.this,"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();
return true;
}
});
popup.show();//showing popup menu
}
});//closing the setOnClickListener method
