在我的项目中，我使用以下代码在Android媒体播放器中播放音乐文件
MediaPlayer mPlayer = MediaPlayer.create(MyActivity.this, R.raw.myfile);
mPlayer.start();
以上是在播放按钮的onclick中编码的。 我想通过再次点击相同的按钮来暂停播放。我的单个按钮用于播放/暂停。 我该怎么办呢。

您可以使用简单的if-check来处理暂停。试试这个：
if(mPlayer.isPlaying()){
mPlayer.pause();
} else {
mPlayer.start();
}

请尝试此::
final Button bPlay = (Button) findViewById(R.id.bPlay);
MediaPlayer song1 = MediaPlayer.create(tutorialFour.this, R.raw.fluet);
Button bStop = (Button) findViewById(R.id.bStop);
bPlay.setWidth(10);
song1.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
bPlay.setText("Play");
}
});
bPlay.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
b = true;
if (bPlay.getText().equals("Play") && b == true) {
song1.start();
bPlay.setText("Pause");
b = false;
} else if (bPlay.getText().equals("Pause")) {
x = song1.getCurrentPosition();
song1.pause();
bPlay.setText("Resume");
Log.v("log", "" + x);
b = false;
} else if (bPlay.getText().equals("Resume") && b == true) {
song1.seekTo(x);
song1.start();
bPlay.setText("Pause");
b = false;
}
}
});

在按钮内单击检查mediaPlayer.isPlaying()。如果媒体播放器正在播放其他错误，则返回true。
所以现在用这个标志值，你可以制作一个if语句并切换到播放或暂停，就像这样，
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if (mediaplayer.isPlaying()) {
mediaplayer.pause();
} else {
mediaplayer.start();
}
}
});

下面的代码会处理您的播放/暂停按钮点击事件以及前进和后退按钮，用于在所提供的搜索栏上进行向前和向后搜索（与媒体轨道同步）。目前它只播放一首歌。但是，您可以添加到该。这是我第一个使用mediaplayer class的媒体播放器，因此您可能会发现它有点原始。但是，如果您需要，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出现。这样可以更容易地设计播放器。

公共类MainActivity扩展了AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//这首歌以前保存在原始文件夹中。这首歌的名字是mylife（它是一个mp3文件） 最终MediaPlayer mMediaPlayer = MediaPlayer.create（MainActivity.this，R.raw.mylife）;
// Play song
Button playButton = (Button) findViewById(R.id.play);
playButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
mMediaPlayer.start(); // no need to call prepare(); create() does that for you
}
});
// Pause song
Button pauseButton = (Button) findViewById(R.id.pause);
pauseButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
mMediaPlayer.pause();
}
});
// Stop song - when you stop a song, you can't play it again. First you need to prepare it.
Button stopButton = (Button) findViewById(R.id.stop);
stopButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {

暂停Mediaplayer：
Mediaplayer.pause();
length = Mediaplayer.getCurrentPosition();
并且从最近停止的位置恢复玩家是通过以下方式完成的：
Mediaplayer.seekTo(length);
Mediaplayer.start();
