我有播放背景音乐的服务。我的活动有一个2.5秒倒数计时器,当活动开始也计时器启动时,我已经将服务开始于OnFinish方法的计时器,意味着音乐应该在活动开始后2.5秒播放,但我的问题是音乐同时开始播放活动开始时。 谢谢你的回答。 这是我的计时器:
if (first.getString("f", "0").equals("0")) {
t1.setVisibility(View.INVISIBLE);
t2.setVisibility(View.INVISIBLE);
m.setVisibility(View.INVISIBLE);
p2.setVisibility(View.INVISIBLE);
p.setVisibility(View.INVISIBLE);
h.setVisibility(View.INVISIBLE);
t3.setVisibility(View.INVISIBLE);
final CountDownTimer Count = new CountDownTimer(2500, 1000) {
final ImageView im = (ImageView) findViewById(R.id.imageView2);
public void onTick(long millisUntilFinished) {
}
public void onFinish() {
t1.setVisibility(View.VISIBLE);
t2.setVisibility(View.VISIBLE);
m.setVisibility(View.VISIBLE);
p2.setVisibility(View.VISIBLE);
p.setVisibility(View.VISIBLE);
h.setVisibility(View.VISIBLE);
im.setVisibility(View.INVISIBLE);
m.setImageResource(R.drawable.music);
m.setTag(R.drawable.music);
**startService(new Intent(main.this, music.class));**
medit.putString("m", "0");
medit.commit();
}
};
Count.start();
editor.putString("f", "1");
editor.commit();
}
else {
final ImageView im = (ImageView) findViewById(R.id.imageView2);
im.setVisibility(View.INVISIBLE);
t3.setVisibility(View.INVISIBLE);
}
这是我的服务:
public class music extends Service {
public music() {
}
MediaPlayer mp;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
mp= MediaPlayer.create(music.this, R.raw.theme);
mp.setLooping(true);
}
@Override
public void onStart(Intent intent, int startId) {
mp.start();
}
@Override
public void onDestroy() {
super.onDestroy();
mp.stop();
}
}
