自己寫的android鬧鐘功能，需要實現timepicker選擇完成后將選擇的時間設定為鬧鐘的啟動時間，但是不管怎么改總是沒法定時啟動

alertDialog = new AlertDialog.Builder(context)

.setView(view)

.setCustomTitle(viewTitle)

.setNegativeButton("確定", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

hour = timePicker.getCurrentHour();

minute = timePicker.getCurrentMinute();

time = new StringBuilder();

time.append(hour < 10 ? "0" + hour : hour).append(":")

.append(minute < 10 ? "0" + minute : minute);

button.setText(time);

calendar.set(Calendar.HOUR, hour);

calendar.set(Calendar.MINUTE, minute);

calendar.set(Calendar.SECOND, 0);

intent = new Intent(context, AlarmNotifyReceiver.class);

pi = PendingIntent.getBroadcast(context, 0, intent,PendingIntent.FLAG_CANCEL_CURRENT);

manager = (AlarmManager) context

.getSystemService(context.ALARM_SERVICE);

manager.setWindow(AlarmManager.RTC_WAKEUP,

calendar.getTimeInMillis(),

1000 * 60 * 60 * 24, pi);

Toast.makeText(context, "鬧鐘設置為" + time,

Toast.LENGTH_SHORT).show();

dialog.cancel();

}

})

.setPositiveButton("取消", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

dialog.cancel();

}

}).create();

alertDialog.setOnShowListener(new OnShowListener() {

@Override

public void onShow(DialogInterface dialog) {

int divierId = alertDialog.getContext().getResources()

.getIdentifier("android:id/titleDivider", null, null);

View divider = alertDialog.findViewById(divierId);

divider.setBackgroundColor(context.getResources().getColor(

R.color.theme_background)); // earlier defined color-int

}

});

alertDialog.show();

接下來是接收廣播的類

public void onReceive(Context context, Intent intent) {

Toast.makeText(context, "啟動鬧鐘", Toast.LENGTH_SHORT).show();

notice = MediaPlayer.create(context,

RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM));

notice.setLooping(true);

try {

notice.setAudioStreamType(AudioManager.STREAM_ALARM);

notice.prepare();

notice.start();

} catch (IllegalStateException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

Builder builder = new AlertDialog.Builder(context);

builder.setTitle("日常提醒鬧鐘").setMessage("請執行操作")

.setPositiveButton("好噠~~", new OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

notice.stop();

}

});

AlertDialog dialog=builder.create();

dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);

dialog.show();

}

寫了Service沒，要在注冊廣播

是不是時間設置錯了，你的TimePicker設置setOnTimeChangedListener來監聽時間的更新了沒
