使用AlarmManager设置重复通知 - Android

标签: android notifications alarmmanager repeatingalarm

我正在使用TimePicker从用户那里获取特定时间。我正在利用这段时间每天在这个时间设置重复闹钟。当闹钟响起时,我想要将通知发送给用户。我的代码似乎是正确的,我没有在Android工作室中得到任何错误,但当我运行这个应用程序并在特定时间设置它...它永远不会关闭。请帮忙。此外,我还没有找到任何能告诉我如何使用TimePicker选择AM或PM用户的东西。我的代码如下。提前谢谢。

这是MyActivity(在发布时打开的那个)

public class MyActivity extends Activity {

TimePicker mTimePicker;
Button setAlarm;
private int hour;
private int minute;
PendingIntent mPendingIntent;
int AM_PM;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);



    setAlarm = (Button) findViewById(R.id.setUpAlarm);


    mTimePicker = (TimePicker) findViewById(R.id.timePicker);

    setAlarm.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            setAlarm();



        }
    });



}

private void setAlarm() {
    hour = mTimePicker.getCurrentHour();
    minute = mTimePicker.getCurrentMinute();

    Intent intent = new Intent(this, NotifyService.class);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    mPendingIntent = PendingIntent.getService(this, 0, intent, 0);

    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.SECOND , 0 );
    calendar.set(Calendar.MINUTE , 0 + minute);
    calendar.set(Calendar.HOUR , 0 + hour);
    calendar.set(Calendar.AM_PM , Calendar.PM);


    Toast.makeText(this, calendar.get(Calendar.MINUTE) + "    " + calendar.get(Calendar.HOUR), Toast.LENGTH_SHORT).show();

    //  * 60 * 60 * 24

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP , calendar.getTimeInMillis() , 1000 * 60 * 60 * 24 , mPendingIntent);

    // Toast.makeText(MyActivity.this , "Alarm Set" , Toast.LENGTH_SHORT).show();
}

这是我的通知类

public class NotifyService extends Service {
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {

    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationManager mNM = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    Intent intent = new Intent(this.getApplicationContext() , MyActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent ,0 );

    Notification mNotify = new Notification.Builder(this)
            .setContentTitle("Come Back!")
            .setContentText("Have you seen todays tip?")
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentIntent(pendingIntent)
            .setSound(sound)
            .build();

    mNM.notify( 1 , mNotify);

}

}

我的清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.androidy.notificationapp" >

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

您必须在清单中声明您的服务,否则无法启动。

此外,getCurrentHour()始终以24小时格式返回小时,无需知道用户是在AM还是PM中输入。

您可能还想考虑将服务中的所有工作从onCreate()移到onStartCommand(),因为只有当您的服务尚未存在时才会调用onCreate(),因为您可以似乎要阻止它(你也可以考虑做)。
