我正在尝试编写一个简单的Android MediaPlayer代码.我在停止播放歌曲并重新启动时遇到问题.在每个按钮中单击.否则，如果我不停止播放曲目，请在每个按钮中单击歌曲不播放，直到歌曲停止播放.

I am trying to write a simple Android MediaPlayer code. I am facing an issue while stopping a song and restart again. In each button click. Otherwise , if i wont stop the track then , in each button click the song is not playing , it wait until the songs stops.

我的要求是，在每个按钮中单击歌曲应从头开始.

My requirement is , in each button click the song should start from the beginning.

我的代码:

package com.example.musicexample; import android.media.MediaPlayer; import android.os.Bundle; import android.support.v7.app.ActionBarActivity; import android.view.View; import android.widget.Button; public class MainActivity extends ActionBarActivity { Button btnPlay; MediaPlayer mPlayer; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btnPlay = (Button) findViewById(R.id.btnPlay); mPlayer = MediaPlayer.create(getApplicationContext(), R.raw.a); btnPlay.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { if(mPlayer.isPlaying()){ mPlayer.stop(); mPlayer.reset(); } mPlayer.start(); } }); } }

在上面的代码中，歌曲随后播放一次，不再播放.

In the above code , the song plays once then , it won't play again.

因此，请仔细阅读，如果我正在播放歌曲，如何停止播放曲目，然后从头开始重新播放呢.

So please go through it , please let me know , how can i stop the track if the song is playing and then restart it from beginning.

推荐答案

您可以尝试以下操作:

MediaPlayer m1 = null; play1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { stopPlaying(); m1=MediaPlayer.create(MainActivity.this, R.raw.a); m1.start(); } }); private void stopPlaying() { if (mp1 != null) { m1.stop(); m1.release(); m1 = null; }
