我正在发出警报,以便在关闭项目时如何停止声音????因为当我关闭它时声音仍在播放,如何阻止它?我已经把它放了但是没有用:
@Override
protected void onStop(){
super.onStop();
//your code for stopping the sound
}
这是代码
public class MainActivity extends Activity {
ImageView img;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
MediaPlayer media = MediaPlayer.create(getBaseContext(), R.raw.alarm);
media.start();
img = (ImageView) findViewById(R.id.img);
img.setImageResource(R.drawable.image1);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

我在项目中使用的是:
在主要活动中声明Ringtone
的实例
Ringtone ringtone;
开始播放声音:
ringtone = RingtoneManager.getRingtone(this, Uri.parse(ringUri));
ringtone.play();
如果ringUri是uri
你要播放的铃声或声音。
停止声音:
ringtone.stop();

将MediaPlayer媒体变量设为全局变量,当onStop触发时,您可以将其停在那里:
private MediaPlayer media;
@Override
protected void onStop(){
super.onStop();
//your code for stopping the sound
if( media != null && media.isPlaying()) {
media.stop();
}
}
