我正在嘗試製作一個應用程序，允許用戶使用兩個TimePickers輸入兩次，手機將在這些時間之間設置爲無聲。我正在使用PendingIntent和AlarmManager在用戶選擇的時間觸發BroadcastReceiver。目前，當用戶點擊保存按鈕時，立即開啓和關閉手機。然後我的「鬧鐘預定」烤麪包就會出現，我的「收到的廣播」會出現兩次，但在此之後它什麼也不做。待處理意圖立即觸發

這裏是我的主要活動代碼：

public class MainActivity extends AppCompatActivity { 

AlarmManager alarm; 
TimePicker timePickerStart; 
TimePicker timePickerEnd; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    timePickerStart = (TimePicker)findViewById(R.id.timePickerStart); 
    timePickerStart.setIs24HourView(true); 
    timePickerEnd = (TimePicker)findViewById(R.id.timePickerEnd); 
    timePickerEnd.setIs24HourView(true); 

} 


//method is called when save button is clicked 
public void setAlarm(View view) { 
    Calendar calendarStart; 
    Calendar calendarEnd; 

    calendarStart = Calendar.getInstance(); 
    calendarEnd = Calendar.getInstance(); 


    //Set calendars to the times in both TimePickers 
    calendarStart.set(Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, timePickerStart.getCurrentHour(), timePickerStart.getCurrentMinute()); 
    long startTimeMillis = calendarStart.getTimeInMillis(); 

    calendarEnd.set(Calendar.YEAR, Calendar.MONTH, Calendar.DAY_OF_MONTH, timePickerEnd.getCurrentHour(), timePickerEnd.getCurrentMinute()); 
    long endTimeMillis = calendarEnd.getTimeInMillis(); 



    //create an intent and set the class that will be triggered by the intent 
    Intent intent = new Intent(MainActivity.this, Receiver.class); 
    PendingIntent pIntent = null; 
    pIntent = PendingIntent.getBroadcast(this, 123, intent, PendingIntent.FLAG_UPDATE_CURRENT); 


    //create alarm manager 
    alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    //set alarms to go off at the time specified by the timePickers 
    alarm.set(AlarmManager.RTC_WAKEUP, calendarStart.getTimeInMillis(), pIntent); 
    alarm.set(AlarmManager.RTC_WAKEUP, calendarEnd.getTimeInMillis(), pIntent); 

    //Toast for feedback 
    Toast.makeText(this, "Alarm Scheduled", Toast.LENGTH_SHORT).show(); 

}

這裏是我的廣播接收器：

public class Receiver extends BroadcastReceiver { 

AudioManager audioManager; 
int modeNum; 


@Override 
public void onReceive(Context context, Intent intent) { 

    //toast for feedback 
    Toast.makeText(context, "Broadcast Received", Toast.LENGTH_SHORT).show(); 


    audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE); 

    modeNum = audioManager.getRingerMode(); 
    if (modeNum == 0) { 
     audioManager.setRingerMode(2); 
    } else { 
     audioManager.setRingerMode(0); 
    } 
}

}

這是我的清單：

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name=".MainActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <receiver android:name=".Receiver"></receiver> 
</application>

你有多個問題。

首先，您嘗試使用相同的PendingIntent創建兩個警報。這是行不通的。你的第二個報警請求將取消第一個報警請求。您需要不同PendingIntent對象，這意味着要麼與PendingIntent對象包裝的對象實質上不同，要麼使用兩個不同的值，即123。

二，您的set()來電Calendar不正確。例如，在這兩個地方，你的第一個參數應該是年份。您正在通過Calendar.YEAR，這是1，而不是2015。
