我正在尝试编写一个程序，根据时间让手机静音。所以，例如，我按一个按钮，我可以设置开始时间和结束时间。在那个开始时间，手机会静音。在那个结束时，手机将返回常规铃声模式。目前它会使手机静音，但一旦达到结束时间就不会恢复到常规模式。从以前试图解决这个问题的尝试中我注释了很多东西。未注释的部分是我目前拥有的。我真的希望得到一些关于这个问题的帮助/指导。

了解Service - 它会投放。问题在于当时不存在aktiviti，如何打开声音。

让我们执行这些步骤......
创建意向服务以取消静音手机
public class SetToNormalService extends IntentService {
public SetToNormalService(String name) { super(name); }
public SetToNomralService() { super(null); }
@Override
protected void onHandleIntent(Intent intent) {
// set the phone ringer to normal
mAudioManager =(AudioManager)getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
}
}
在按钮事件中，将手机设置为静音并启动AlarmManager
public void SilentAndSetAlarm(Context context,long triggerAtMillis, long intervalMillis) {
// set the phone to silent
mAudioManager =(AudioManager)PresetEdit.this.getSystemService(Context.AUDIO_SERVICE);
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
// Initialize the AlarmManager
Intent intent = new Intent(context, SetToNomralService.class);
PendingIntent pIntent = PendingIntent.getService(context, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerAtMillis, intervalMillis, pIntent);
}
多数人......
备注： 你不需要调用任何构造函数......但是如果删除带有参数'name'的那个，它将抛出一个异常......所以保持原样......
对于millis ......你可以使用
//get current time object
Date date = new Date();
// set its hours and mimuts that you got from time picker
date.setHours(hoursOfDay);
date.setMinutes(minutesOfDay);
//getTime will give you millisecond of date object
long timeInMillis = date.getTime();
以这种方式...你可以将你的eHours和eMinutes转换为millis，startTime和intervalTime ......
