在按钮上显示图像（或媒体）单击随机更改布局

Question

我想随机显示5个xml布局，并且还可以在适当的按钮上点击每个出现的xml文件来随机播放它们。高兴地说，下面的代码工作真棒.---- ** 我已经把每个shuffle的xml文件延迟0.75秒。在这个延迟我有一个声音play.I没有真正的想法如何实现这一点。在下面的代码中我使用了Switch-Case，但它不工作。我的要求是，如果我点击xml文件1上的按钮，我想播放Sound1，如果Button是来自Xml文件5，我想要播放相应的Sound5等等......就这样，持续0.75秒，然后移动到下一个XML文件并重复循环。 * ----

        } 


        mPosition++;

        mButton.setOnClickListener(mListener);

      }, 2050); 
     } 
    }; 


        mPosition++; 
        mButton = (Button)findViewById(R.id.btnid); 
        mButton.setOnClickListener(mListener); 
       } 
      }, 750); 
     } 
    }; 
} 

任何种类的帮助是非常有帮助的。

您可以使用android：标记来区分按钮。

<Button 
    ... 
    android:tag="1"/> 

然后在代码检索标签

mButton = (Button)findViewById(R.id.btnid); 
int id = Integer.parseInt(mButton.getTag()); 

switch(id) { 
    ... 
}
