Question

我正在为Android项目中的闹钟工作，我是编程新手。我的闹钟应用程序正常运行，但它不能用于计划时间，因此如果我将时钟设置为星期日下午12点，它将无效。

 public class AlarmClock extends Activity {
    private PendingIntent pendingIntent;
    private TimePicker alarmTimePicker;
    AlarmManager alarmManager;
    private EditText descriptionText;
    private static MainActivity inst;
    private CheckBox checkBox1,checkBox2,checkBox3,checkBox4,checkBox5,checkBox6,checkBox7;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_alarm_clock);
        alarmTimePicker = (TimePicker) findViewById(R.id.alarmTimePicker);
        alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        checkBox1= (CheckBox) findViewById(R.id.sundayCheckBox);
        checkBox2= (CheckBox) findViewById(R.id.mondayCheckBox);
        checkBox3= (CheckBox) findViewById(R.id.tuesdayCheckBox);
        checkBox4= (CheckBox) findViewById(R.id.wednesdayCheckBox);
        checkBox5= (CheckBox) findViewById(R.id.thursdayCheckBox);
        checkBox6= (CheckBox) findViewById(R.id.fridayCheckBox);
        checkBox7= (CheckBox) findViewById(R.id.saturdayCheckBox);




    }
    public void save (View v){
        if (checkBox1.isChecked())
        {
            activityToPerform(1);
        }

        if (checkBox2.isChecked())
        {
            activityToPerform(2);
        }

        if (checkBox3.isChecked())
        {
            activityToPerform(3);
        }

        if (checkBox4.isChecked())
        {
            activityToPerform(4);
        }

        if (checkBox5.isChecked())
        {
            activityToPerform(5);
        }

        if (checkBox6.isChecked())
        {
            activityToPerform(6);
        }

        if (checkBox7.isChecked())
        {
            activityToPerform(7);
        }



    }
    private void activityToPerform(int week)
    {
        Log.d("MainActivity", "Alarm On");
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.DAY_OF_WEEK, week);
        calendar.set(Calendar.HOUR_OF_DAY, alarmTimePicker.getCurrentHour());
        calendar.set(Calendar.MINUTE, alarmTimePicker.getCurrentMinute());
        descriptionText= (EditText)findViewById(R.id.descriptionEditText);
        Intent myIntent = new Intent(this, AlarmBroadcast.class);
        pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
    }

启动API 19时，alarmManager.set()方法未在准确时间传递。请参阅：http://developer.android.com/reference/android/app/AlarmManager.html#set(int，long，android.app.PendingIntent）

您应该使用setExact()代替

闹钟不适用于日程安排时间和日期
