Android:在某些操作上显示弹出菜单？

Question

好的,所以我知道你可以在用户长时间点击一个项目时创建一个上下文菜单...但我可以这样做,这样当用户在项目或屏幕上说双击时会出现弹出菜单吗？谢谢

您可以显示如下警告对话框:

private void showDialog()
{
   final CharSequence[] options = {"Option1", "Option2", "etc.."};

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Title here");

    builder.setItems(options, new DialogInterface.OnClickListener()
    {
        @Override
        public void onClick(DialogInterface dialog, int which)
        {
           if (which == 0)//Option 1
           {
           }
           else if (which == 1)//Option 2
           {
           }
           //etc..
        } 
    });

    AlertDialog dlg = builder.create();
   dlg.show();
}
