TimePicker崩潰應用程序

但是，當調用intent時應用程序崩潰，從TimePicker對話框中設置Alarm。TimePicker崩潰應用程序

這裏是代碼的對話框：

public void clicker (View view) 
{ 
    Calendar calendar = Calendar.getInstance(); 

    TimePickerDialog mTimePicker; 
    mTimePicker = new TimePickerDialog(AddAlarm.this, 
     new TimePickerDialog.OnTimeSetListener() { 
      @Override 
      public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) { 
       Calendar calendar = Calendar.getInstance(); 
       calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour()); 
       calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute()); 

       Intent myIntent = new Intent(AddAlarm.this, AlarmReceiver.class); 
       pendingIntent = PendingIntent.getBroadcast(AddAlarm.this, 0, myIntent, 0); 

       alarmManager.set(AlarmManager.RTC_WAKEUP, 
        calendar.getTimeInMillis(), 
        pendingIntent); 
      } 
     }, hour, minute, false);// Yes 24 hour time 

    mTimePicker.setTitle("Select Time"); 
    mTimePicker.show(); 
}

這裏是logcat的：

這是當我按下ImageButton的啓動TimePicker對話會發生什麼。我想錯誤在於通過意圖傳遞時間。任何幫助將不勝感激。

你在哪裏通過意向發送/接收時間值？ –

調試你的代碼並檢查'Null'返回的位置 – hrskrs

@oblivion你試過告訴我關於這個bug的情況嗎？ –

試一下這個

public void clicker (View view) 
{ 
    Calendar calendar = Calendar.getInstance(); 

    final TimePickerDialog mTimePicker; 
    mTimePicker = new TimePickerDialog(AddAlarm.this, 
     new TimePickerDialog.OnTimeSetListener() { 
      @Override 
      public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) { 
       timePicker = mTimepicker; 
       Calendar calendar = Calendar.getInstance(); 
       calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour()); 
       calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute()); 

       Intent myIntent = new Intent(AddAlarm.this, AlarmReceiver.class); 
       pendingIntent = PendingIntent.getBroadcast(AddAlarm.this, 0, myIntent, 0); 

       alarmManager.set(AlarmManager.RTC_WAKEUP, 
        calendar.getTimeInMillis(), 
        pendingIntent); 
      } 
     }, hour, minute, false);// Yes 24 hour time 

    mTimePicker.setTitle("Select Time"); 
    mTimePicker.show(); 
}

你做

calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour()); 
calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute());

您應該使用selectedHour和selectedMinute

calendar.set(Calendar.HOUR_OF_DAY, selectedHour); 
calendar.set(Calendar.MINUTE, selectedMinute);

這應該工作，並確保你做的一切都是正確的與ImageView的所有最好的

清除錯誤夥伴，但警報不會在設定的時間播放:( – OBX

確定嘗試更改此線路pendingIntent = PendingIntent.getBroadcast（AddAlarm.this，0，myIntent，pendingIntent.FLAG_ONE_SHOT）;並將RTC_WAKEUP僅更改爲RTC .. – Prakhar
