Android开发之MediaPlayer基本使用方法详解-创新互联

本文实例讲述了Android MediaPlayer基本使用方法。分享给大家供大家参考，具体如下：

使用MediaPlayer播放音频或者视频的最简单例子：

Java代码部分：

public class MediaPlayerStudy extends Activity {
  private Button bplay,bpause,bstop;
  private MediaPlayer mp = new MediaPlayer();
  @Override
  public void onCreate(BundlesavedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    bplay =(Button)findViewById(R.id.play);
    bpause =(Button)findViewById(R.id.pause);
    bstop =(Button)findViewById(R.id.stop);
    bplay.setOnClickListener(new OnClickListener(){
      @Override
      public void onClick(View v) {
         try {
           mp.setDataSource("/sdcard/test.mp3");
           mp.prepare();
           mp.start();
         } catch (IllegalArgumentException e){
           e.printStackTrace();
         } catch (IllegalStateException e){
           e.printStackTrace();
         } catch (IOException e) {
           e.printStackTrace();
         }
         mp.setOnCompletionListener(new OnCompletionListener(){
           @Override
           public void onCompletion(MediaPlayer mp){
             mp.release();
           }
         });
      }
    });
    bpause.setOnClickListener(new OnClickListener(){
      @Override
      public void onClick(View v) {
         if(mp != null){
           mp.pause();
         }
      }
    });
    bstop.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v) {
       if(mp != null){
        mp.stop();
       }
    }
    });
  }
  @Override
  protected void onDestroy() {
    if(mp != null)
      mp.release();
    super.onDestroy();
  }
}
