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 String mDate;
private LinearLayout llDate;
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
public void onClick(View v) {
switch (v.getId()) {
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)){

break;
}
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date;
long value = 0;
String str_date = mDate+" "+mTime;
try {

System.out.println("当前设置时间:"+value);
} catch (ParseException e) {

}

if(value<=value2){

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);

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.schedule(new TimerTask() {
@Override
public void run() {

.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

4.日期工具类 和布局

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();
}
});
builder.setNegativeButton("取 消",
new DialogInterface.OnClickListener() {
@Override

}
});
builder.create().show();
}
});
}

final DatePicker datePicker = (DatePicker) view
.findViewById(R.id.date_picker);
// 设置日期简略显示 否则详细显示 包括:星期\周
datePicker.setCalendarViewShown(false);
// 初始化当前日期
calendar.setTimeInMillis(System.currentTimeMillis());
datePicker.init(calendar.get(Calendar.YEAR),

// 日期格式
StringBuffer sb = new StringBuffer();
sb.append(String.format("%d-%02d-%02d",
datePicker.getYear(),
datePicker.getMonth() + 1,
datePicker.getDayOfMonth()));
date.setText(sb);
// 赋值后面闹钟使用
mYear = datePicker.getYear();
mMonth = datePicker.getMonth();
mDay = datePicker.getDayOfMonth();
dialog.cancel();
}
});
builder.setNegativeButton("取 消",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,

dialog.cancel();
}
});

}
});
