android日程安排任务在特定时间每天执行

我想在特定时间每天更改我的铃声音量。我使用日历来指定时间，并且我试图使用alarmManager来执行它。这是我的。（我是noobie去容易对我）android日程安排任务在特定时间每天执行

package com.example.ringervolume.app; 

import android.app.Activity;

     Calendar calendaram = Calendar.getInstance(); 

     calendaram.set(Calendar.HOUR_OF_DAY, 21); 
     calendaram.set(Calendar.MINUTE, 32); 
     calendaram.set(Calendar.SECOND, 0); 
     calendaram.set(Calendar.AM_PM,Calendar.PM); 



     Intent myIntent = new Intent(MainActivity.this, MyReceiver.class); 
     pendingIntentam = PendingIntent.getBroadcast(MainActivity.this, 0,myIntent,0); 
     AlarmManager alarmManageram = (AlarmManager)getSystemService(ALARM_SERVICE);

是什么你的代码有错？ – Raghunandan

我忘了添加它，基本上它不会设置音量在我指定的时间振动。 – andyADD

您有另一个活动作为当前活动的内部类。将它移动到一个单独的'.java'文件。另请参阅是否已注册广播接收器。 – Raghunandan

要报警日常火，在21:32

private AlarmManager alarmMgr; 
private PendingIntent alarmIntent; 
... 
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
Intent intent = new Intent(context, AlarmReceiver.class); 
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 

// Set the alarm to start at 21:32 PM 
Calendar calendar = Calendar.getInstance(); 
calendar.setTimeInMillis(System.currentTimeMillis()); 
calendar.set(Calendar.HOUR_OF_DAY, 21); 
calendar.set(Calendar.MINUTE, 32); 

// setRepeating() lets you specify a precise custom interval--in this case, 
// 1 day 
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 
     AlarmManager.INTERVAL_DAY, alarmIntent);

在这种情况下，AlarmReceiver是广播接收器，它已经有一个背景，所以您可以直接将广播接收器的铃声模式设置为无声，而无需启动任何活动。

@Override 
    public void onReceive(Context context, Intent intent) { 
     AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE); 
     am.setRingerMode(AudioManager.RINGER_MODE_SILENT); 
}

请一定要添加这些权限：

<uses-permission android:name="android.permission.WRITE_SETTINGS" ></uses-permission> 
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" ></uses-permission> 
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" ></uses-permission>

谢谢你的回应，这是包含意向意图的行，它说不能解决symbole的“上下文”有什么想法是什么意思？ – andyADD

使用MainReceiver.this来代替上下文变量。 –

谢谢，我给了它另一个镜头，但它似乎不工作，我一直在努力理解logcat为什么它不工作的意义。 – andyADD

如果Shivam维尔马的答案不为你工作，请确保您的接收器添加到您的清单：

<receiver android:name=".receivers.MyReceiver" />
