Question

详细代码如下，我想实现10秒音乐播放，音乐停止后自动停止，然后到另一个活动，当前问题是在启动画面期间按下主页键时发生错误，另一个活动仍然可以进入（这是不合理的......）任何人都可以给我一些帮助吗？

公共类ActivitySplash扩展了Activity { 私有静态MediaPlayer playSong;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.splash);

    fontsCustom();

    playSong = MediaPlayer.create(ActivitySplash.this,
            R.raw.fsir200splashmusic);
    playSong.start();

    Thread timer = new Thread() {
        public void run() {
            try {
                while (playSong.isPlaying()) {
                    sleep(500);
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            } finally {
                Intent beginActivityInt = new Intent(
                        "android.intent.action.ACTIVITYMAIN");
                startActivity(beginActivityInt);
            }

        }
    };
    timer.start();
}

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_MENU) {

        return true; // always eat it!
    } else if (keyCode == KeyEvent.KEYCODE_BACK) {
        return true;
    } else if (keyCode == KeyEvent.KEYCODE_HOME)
        return true;
    else
        return super.onKeyDown(keyCode, event);
}

public void fontsCustom() {
    FontCustom fonts = new FontCustom(ActivitySplash.this);
    LinearLayout layout = (LinearLayout) findViewById(R.id.id_layout_splash);
    fonts.setupLayoutTypefaces(layout);
}


@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    playSong.release();
    finish();
}

public class SplashActivity extends Activity {
 Thread t;
 MediaPlayer mpl;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
     final SplashActivity ss=this;
    setContentView(R.layout.activity_splash);
    mpl=MediaPlayer.create(this, R.raw.dog1);
    mpl.start();
    mpl=MediaPlayer.create(this, R.raw.cat3);
    mpl.start();

  Thread t=new Thread(){
      public void run() {
          try{
              sleep(10000);
          }
          catch(Exception e){

          }
          mpl.stop();
          Intent i=new Intent(ss,MainActivity.class);
          startActivity(i);
      }
  };
   t.start();

}
}

你必须设置 playsong.OnCompletionListener(ActivitySplash.this)和在

中实现你的逻辑

public void onCompletion(MediaPlayer arg0) 
{
  // Write your code
}

请参阅以下代码：

public class SplashActivity extends Activity {

private static MediaPlayer playsong;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    playsong = MediaPlayer.create(this, R.raw.pp);
    playsong.start();
    playsong.setOnCompletionListener(new OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer mp) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(SplashActivity.this, MainActivity.class);
            startActivity(intent);
        }
    });
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    playsong.release();
    finish();
}

}

随着音乐播放飞溅？
