定时弹出 demo ,代码如下:

1.MainActivity.java

public class MainActivity extends Activity implements OnClickListener {
        private static Context sContext = null;
        private EditText date;
        private EditText time;
        private Button btn;
        private Date_TimeUtil dtUtil;
        private String mTime;

        private LinearLayout llTime;
    
        public static Context getContext() {
            return sContext;
        }
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            sContext = this;
            dtUtil = new Date_TimeUtil(this);
            initView();
            init();
        }
    
        private void initView() {
            date = (EditText) findViewById(R.id.date);
            time = (EditText) findViewById(R.id.time);
            btn = (Button) findViewById(R.id.btn);
            
            llDate = (LinearLayout) findViewById(R.id.ll_date);
            llTime = (LinearLayout) findViewById(R.id.ll_time);
        }
    
        private void init() {
            //date.setOnClickListener(this);
            //time.setOnClickListener(this);
            btn.setOnClickListener(this);
            llDate.setOnClickListener(this);
            llTime.setOnClickListener(this);
        }
    
        @Override

            case R.id.ll_date:
                dtUtil.setDate(date);
                
                break;
            case R.id.ll_time:
                dtUtil.setTime(time);
                
                break;
            case R.id.btn:
                mDate = date.getText().toString();
                mTime = time.getText().toString();
                Log.e("xx","日期= "+mDate+"   时间= "+mTime);
                if(TextUtils.isEmpty(mDate)){
                    Toast.makeText(getApplicationContext(), "请选择提醒日期", 0).show();
                    break;
                }else if(TextUtils.isEmpty(mTime)){
                    Toast.makeText(getApplicationContext(), "请选择提醒时间", 0).show();
                    break;
                }
                SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                Date date;
                long value = 0;
                String str_date = mDate+" "+mTime;
                try {
                    date = sdf.parse(str_date);
                    value = date.getTime();
                    System.out.println("当前设置时间:"+value);
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                Log.e("str_date=",str_date);
                Log.e("value=",value+"");
                long value2 = System.currentTimeMillis();
                if(value<=value2){
                    Toast.makeText(getApplicationContext(), "选择时间不能小于当前系统时间", 0).show();
                    return;

                int delaytime = (int)(value - value2);
                AlarmService.addNotification(delaytime,"tick","title","text");
                break;
            }
        }
        
    }

2. 服务类

@SuppressLint("NewApi")
    public class AlarmService extends Service {
    
        static Timer timer = null;
    
        // 清除通知
        public static void cleanAllNotification() {
            NotificationManager mn = (NotificationManager) MainActivity
                    .getContext().getSystemService(NOTIFICATION_SERVICE);
            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

<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
                                public void onClick(DialogInterface dialog,
                                        int which) {
                                    mHour = timePicker.getCurrentHour();
                                    mMinute = timePicker.getCurrentMinute();
                                    // 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)
                                            .append(":")
                                            .append(mMinute < 10 ? "0" + mMinute
                                                    : mMinute).append(":00"));
                                    dialog.cancel();
                                }
