我是一个正在开发运行mp3文件的应用程序,我希望该应用程序在关闭活动后运行mp3文件,在这种情况下,我使用了服务与媒体播放器一起展示Seekbar进度并停止并从活动中播放媒体播放器的活动,我试图在服务和活动之间使用广播,但似乎花费了很多资源,是否有更好的方法来解决这个问题?/p>
这是我完成的一部分
public class Reciver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
int command = intent.getExtras().getInt("command");
if (command == 0) {
progressDialog.setMessage("loading...");
progressDialog.show();
}
if (command == 1) {
int value = intent.getExtras().getInt("value");
seekBar.setMax(value);
int seconds = (value / 1000) % 60;
int minutes = ((value / (1000 * 60)) % 60);
int hours = ((value / (1000 * 60 * 60)) % 24);
if (hours != 0) {
if (seconds < 10) {
durationTV.setText(hours + ":" + minutes + ":0" + seconds);
} else {
durationTV.setText(hours + ":" + minutes + ":" + seconds);
}
} else {
if (seconds < 10) {
durationTV.setText(minutes + ":0" + seconds);
} else {
durationTV.setText(minutes + ":" + seconds);
}
}
progressDialog.dismiss();
}
if (command == 2) {
int currentDuration = intent.getExtras().getInt("value");
if(!movingSeekBar) seekBar.setProgress(currentDuration);
int seconds = (currentDuration / 1000) % 60;
int minutes = ((currentDuration / (1000 * 60)) % 60);
int hours = ((currentDuration / (1000 * 60 * 60)) % 24);
if (hours != 0) {
if (seconds < 10) {
currentPositionTV.setText(hours + ":" + minutes + ":0" + seconds);
} else {
currentPositionTV.setText(hours + ":" + minutes + ":" + seconds);
}
} else {
if (seconds < 10) {
currentPositionTV.setText(minutes + ":0" + seconds);
} else {
currentPositionTV.setText(minutes + ":" + seconds);
}
}
}
if (command == 3) {
bufferPercent = intent.getExtras().getInt("value");
seekBar.setSecondaryProgress(bufferPercent);
Log.d("Media Player", "" + bufferPercent);
}
}
}
我不认为接收器是有效的,加上我的服务也有另一个接收器,如何在背景中播放音乐,同时从活动/服务中控制媒体播放器
使用"绑定服务",然后,它很可能是"绑定的本地服务",可以在此处找到有关此模式的更多信息
