java - "Unfortunately ' 应用程序 ' has stopped"错误

Question

这个问题已经有答案了:

Unfortunately MyApp has stopped. How can I solve this? (23 个回答)

已关闭 9 年前。

这个想法是在闹钟开始时启动游戏。我在下面显示了 Manifest.xml。如果我犯了错误，请纠正我。由于我是Android新手，所以我无法弄清楚。 PS:我搜索了其他类似的问题并纠正了许多其他错误，但问题仍然存在。

这是我从教程(AndroidTimeActivity)中获得的警报代码:

public class AndroidTimeActivity extends Activity {

    TimePicker myTimePicker;
    Button buttonstartSetDialog;
    TextView textAlarmPrompt;

    TimePickerDialog timePickerDialog;

    final static int RQS_1 = 1;

    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    textAlarmPrompt = (TextView)findViewById(R.id.alarmprompt);

    buttonstartSetDialog = (Button)findViewById(R.id.startSetDialog);
    buttonstartSetDialog.setOnClickListener(new OnClickListener(){

                        public void onClick(View v) {
                textAlarmPrompt.setText("");
                openTimePickerDialog(false);

            }});

}


    private void openTimePickerDialog(boolean is24r){
        Calendar calendar = Calendar.getInstance();

        timePickerDialog = new TimePickerDialog(
                AndroidTimeActivity.this, 
                onTimeSetListener, 
                calendar.get(Calendar.HOUR_OF_DAY), 
                calendar.get(Calendar.MINUTE), 
                is24r);
        timePickerDialog.setTitle("Set Alarm Time");  

        timePickerDialog.show();

    }

OnTimeSetListener onTimeSetListener= new OnTimeSetListener(){


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

            Calendar calNow = Calendar.getInstance();
            Calendar calSet = (Calendar) calNow.clone();

            calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
            calSet.set(Calendar.MINUTE, minute);
            calSet.set(Calendar.SECOND, 0);
            calSet.set(Calendar.MILLISECOND, 0);

            if(calSet.compareTo(calNow) <= 0){
                //Today Set time passed, count to tomorrow
                calSet.add(Calendar.DATE, 1);
            }

            setAlarm(calSet);
        }};

    private void setAlarm(Calendar targetCal){

        textAlarmPrompt.setText(
                "\n\n***\n"
                + "Alarm is set@ " + targetCal.getTime() + "\n"
                + "***\n");

Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(),RQS_1,                  
intent, 0);     
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),                                                            
pendingIntent);

    }


}

这是 AlarmReceiver 类:

 public class AlarmReceiver extends BroadcastReceiver {

@Override
    public void onReceive(Context context, Intent arg1) {
         Intent activityIntent = new Intent(context, Manager.class);                    
        activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(activityIntent);

}

 }

这是当警报接收器收到 Intent 时我想要调用的 Manager 类:

       public class Manager extends Activity {
       private static int ROW_COUNT = -1;
    private static int COL_COUNT = -1;
    private Context context;
    private Drawable backImage;
    private int [] [] cards;
    private List<Drawable> images;
    private Card firstCard;
    private Card seconedCard;
    private ButtonListener buttonListener;

    private static Object lock = new Object();

    int turns;
    private TableLayout mainTable;
    private UpdateCardsHandler handler;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);



        handler = new UpdateCardsHandler();
        loadImages();
        setContentView(R.layout.main);


       backImage =  getResources().getDrawable(R.drawable.icon);

 /*
       ((Button)findViewById(R.id.ButtonNew)).setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

        }


    });*/

       buttonListener = new ButtonListener();

    }

这是我的 list ，我确实为 Manager 类创建了一个 Activity ，但是“AndroidTime 已停止”错误仍然存​​在。

public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent arg1) {
  Intent activityIntent = new Intent(context,
