You could use simple if-check to handle the pausing. Try this:

<pre><code>if(mPlayer.isPlaying()){
 mPlayer.pause();
} else {
 mPlayer.start();
}
</code></pre>

Inside the button click check for <code>mediaPlayer.isPlaying()</code>. This will return true if the media player is playing else false. 

So now with this, flag value you can make a if statement and switch to play or pause like this,

<pre><code>button.setOnClickListener(new View.OnClickListener() {

 public void onClick(View view) {

 if (mediaplayer.isPlaying()) {
 mediaplayer.pause();
 } else {
 mediaplayer.start();
 }
 }
 });
</code></pre>

blocks|key|424874|text|下面的代码负责你的播放/暂停按钮点击事件，以及在提供的搜索栏(与媒体音轨同步)上前进和后退搜索的前进和后退按钮。目前它只播放一首歌曲。但是，您可以对其进行补充。这是我第一个使用mediaplayer+class的媒体播放器，所以你可能会觉得它有点原始。但是，如果需要，您还可以查看VideoView示例。使用VideoView显然更容易，因为标准媒体控制台已经以预定义小部件的形式存在。所以这使得设计播放器变得容易得多。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|424875|package+in.org.Test;

Below code takes care of your play/pause button click event along with forward and backward buttons for forward and backward seek on the seekbar provided (which is synchronized with the media track). Currently it plays just ONE song. However, you can add to that. This is my first media player using <code>mediaplayer class</code>, so you might find it a bit primitive. However if you need you can also check out the <code>VideoView</code> examples. It's apparently easier with <code>VideoView</code> as the standard media console is already present in the form of pre-defined widgets. so that makes designing the player much easier.

the above is coded in the onclick of the play button.
I want to pause the playback by clicking the same button again.ie) single button for play/pause.
How shall i do this.
