android 定时提醒

定时弹出 demo ,代码如下:

1.MainActivity.java

public class MainActivity extends Activity implements OnClickListener {

        initView();
        init();
    }

    private void initView() {

    }

    private void init() {
        //date.setOnClickListener(this);
        //time.setOnClickListener(this);
        btn.setOnClickListener(this);
        llDate.setOnClickListener(this);
        llTime.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {

            break;

2. 服务类

@SuppressLint("NewApi")

    public static void cleanAllNotification() {

        mn.cancelAll();
        if (timer != null) {
            timer.cancel();
            timer = null;
        }
    }

    // 添加通知
    public static void addNotification(int delayTime, String tickerText,
            String contentTitle, String contentText) {
        Intent intent = new Intent(MainActivity.getContext(),
                AlarmService.class);
        intent.putExtra("delayTime", delayTime);
        intent.putExtra("tickerText", tickerText);
        intent.putExtra("contentTitle", contentTitle);
        intent.putExtra("contentText", contentText);
        MainActivity.getContext().startService(intent);
    }

    public void onCreate() {
        Log.e("addNotification", "===========create=======");
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    public int onStartCommand(final Intent intent, int flags, int startId) {

        long period = 24 * 60 * 60 * 1000; // 24小时一个周期
        int delay = intent.getIntExtra("delayTime", 0);
        if (null == timer) {
            timer = new Timer();
        }
        timer.schedule(new TimerTask() {

            @Override
            public void run() {
                NotificationManager mn = (NotificationManager) AlarmService.this
                        .getSystemService(NOTIFICATION_SERVICE);
                Notification.Builder builder = new Notification.Builder(
                        AlarmService.this);

                Intent notificationIntent = new Intent(AlarmService.this,
                        MainActivity.class);// 点击跳转位置
                PendingIntent contentIntent = PendingIntent.getActivity(
                        AlarmService.this, 0, notificationIntent, 0);
                builder.setContentIntent(contentIntent);
                builder.setSmallIcon(R.drawable.ic_launcher);// 设置通知图标
                builder.setTicker(intent.getStringExtra("tickerText")); // 测试通知栏标题
                builder.setContentText(intent.getStringExtra("contentText")); // 下拉通知啦内容
                builder.setContentTitle(intent.getStringExtra("contentTitle"));// 下拉通知栏标题
                builder.setAutoCancel(true);// 点击弹出的通知后,让通知将自动取消
                builder.setVibrate(new long[] { 0, 2000, 1000, 4000 }); // 震动需要真机测试-延迟0秒震动2秒延迟1秒震动4秒
                // builder.setSound(Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI,
                // "5"));//获取Android多媒体库内的铃声
                // builder.setSound(Uri.parse("file:///sdcard/xx/xx.mp3"))
                // ;//自定义铃声
                builder.setDefaults(Notification.DEFAULT_ALL);// 设置使用系统默认声音
                // builder.addAction("图标", title, intent); //此处可设置点击后 打开某个页面
                Notification notification = builder.build();
                notification.flags = notification.FLAG_INSISTENT;// 声音无限循环
                mn.notify((int) System.currentTimeMillis(), notification);
            }
        }, delay, period);

        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        Log.e("addNotification", "===========destroy=======");
        super.onDestroy();
    }
}

3.配置文件

<!-- 震动权限 -->
        <uses-permission android:name="android.permission.VIBRATE" />

        <service
            android:name=".AlarmService"
            android:enabled="true"
            android:process="system" >
        </service>

4.日期工具类 和布局

public class Date_TimeUtil {
    private Calendar calendar = Calendar.getInstance();;
    private int mYear, mMonth, mDay;
    private int mHour;
    private Integer mMinute;
    private Context context;

    public Date_TimeUtil(Context context) {
        this.context = context;
    }
    public void setTime(final EditText time) {
        // 点击"时间"按钮布局 设置时间
        time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 自定义控件
                AlertDialog.Builder builder = new AlertDialog.Builder(context);
                View view = (LinearLayout) View.inflate(context,
                        R.layout.time_dialog, null);
                final TimePicker timePicker = (TimePicker) view
                        .findViewById(R.id.time_picker);
                // 初始化时间
                calendar.setTimeInMillis(System.currentTimeMillis());
                timePicker.setIs24HourView(true);
                timePicker.setCurrentHour(calendar.get(Calendar.HOUR_OF_DAY));
                timePicker.setCurrentMinute(Calendar.MINUTE);
                // 设置time布局
                builder.setView(view);
                builder.setTitle("设置时间信息");
                builder.setPositiveButton("确  定",
                        new DialogInterface.OnClickListener() {
                            @Override

                                // 时间小于10的数字 前面补0 如01:12:00
                                time.setText(new StringBuilder()
                                        .append(mHour < 10 ? "0" + mHour
                                                : mHour)
