例外エラー

Question

私はデバイスをサイレントモードにして、ユーザーが設定した所定の時間に正常に戻すアプリを開発しました。ユーザーはイベントの名前を入力し、開始時刻と終了時刻を入力してから、作成ボタンをクリックしてイベントを作成します。私はアプリを実行し、ユーザーがこの時点で私のアプリがクラッシュし、私が理解できない例外をスローする開始時刻を選択します。私は以下の関連コードと例外エラーを掲示しています。

あなたに必要なプロセスのためにこのよう次

public class UnsilenceBroadcastReceiver extends BroadcastReceiver { 
@Override 
public void onReceive(Context context, Intent intent) { 
    AudioManager audio=(AudioManager)context.getSystemService(Context.AUDIO_SERVICE); 
    audio.setRingerMode(AudioManager.RINGER_MODE_NORMAL); 
}} 

Answer 1

試してみてください。

Calendar calender = Calendar.getInstance(); 
    myTimePicker = new TimePickerDialog(this, new OnTimeSetListener() { 

     public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 


      Calendar newTime = Calendar.getInstance(); 

      //newTime.set(hourOfDay, minute); // remove this line 

      //Add these two line 
      newTime.set(Calendar.HOUR_OF_DAY, hourOfDay); 
      newTime.set(Calendar.MINUTE, minute); 

      GotTime = GotDate + " At " + String.valueOf(hourOfDay) + " :" + String.valueOf(minute + 1); 
      time.setText(GotTime); 
     } 
    }, calender.get((Calendar.HOUR_OF_DAY)), calender.get(Calendar.MINUTE), true); 
}
