Android的：如何检查自己是否达到/接近我的目标？ [英] Android: How to check that whether i reach/near my Destination?

问题描述

我发展，当你到达/目的地附近，接到通知像闹钟唤醒了你的应用程序。

这是任何方式，我是否连续检查用户的当前位置，当用户接近/到达目的地？

如果有可能比请给我品尝/教程，这样我可以很容易地实现它。

到现在为止，我实现低于code，表示通知。

 公共类ProximityReceiver扩展广播接收器{私有静态最终诠释ALARM_DURATION = 6000;
公共静态最后弦乐INTENT_NAME =com.xxx.xxx.intent.PROXIMITY;
私有静态最后长VIBRATION_PATTERN [];静态的 {
    长人[] =新长[6];
    [1] = 1000L;
    [2] = 500L;
    [3] = 1000L;
    [4] = 500L;
    [5] = 1000L;
    VIBRATION_PATTERN =人;
}@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{    MyMainApplication wakeappapplication =（MyMainApplication）上下文
            .getApplicationContext（）;    如果（wakeappapplication.getStatus（）。等于（WakeAppStatus.STARTED））{
        wakeappapplication.setStatus（WakeAppStatus.APPROACHING）;
        长L = 6000L + System.currentTimeMillis的（）;
        （（AlarmManager）context.getSystemService（报警））。setRepeating（0，

解决方案

您应该创建一个地理围栏，并把它添加到谷歌定位服务，当用户在一个特定的地理围栏进入或退出它，它会通知您（回调）。

I am developing an application that wakeup to you when you reach/near your destination and send you notification like Alarm.

Is it any way whether i check continuously user's current location and when user is near/reach destination?

If it is possible than please give me sample/tutorial so that i can implement it easily.

Till now,i implement below code that indicates "Notification".

public class ProximityReceiver extends BroadcastReceiver {

private static final int ALARM_DURATION = 6000;
public static final String INTENT_NAME = "com.xxx.xxx.intent.PROXIMITY";
private static final long VIBRATION_PATTERN[];

static {
    long al[] = new long[6];
    al[1] = 1000L;
    al[2] = 500L;
    al[3] = 1000L;
    al[4] = 500L;
    al[5] = 1000L;
    VIBRATION_PATTERN = al;
}

@Override
public void onReceive(Context context, Intent intent) {



    MyMainApplication wakeappapplication = (MyMainApplication) context
            .getApplicationContext();

    if (wakeappapplication.getStatus().equals(WakeAppStatus.STARTED)) {
        wakeappapplication.setStatus(WakeAppStatus.APPROACHING);
        long l = 6000L + System.currentTimeMillis();
        ((AlarmManager) context.getSystemService("alarm")).setRepeating(0,
                l, 6000L, wakeappapplication.getProximityPendingIntent());
    }

    NotificationManager notificationmanager = (NotificationManager) context
            .getSystemService("notification");

    notificationmanager.cancel("ProximityReceiver", 0);

    Notification notification = new Notification(
            R.drawable.ic_stat_notify_wakeapp,
            context.getString(R.string.text_wake_title),
            System.currentTimeMillis());

    PendingIntent pendingintent = PendingIntent.getActivity(context, 0,
            new Intent(context, MainWakeMeUpActivity.class), 0);

    notification.setLatestEventInfo(context,
            context.getString(R.string.text_wake_title),
            context.getString(R.string.text_wake_descr), pendingintent);

    android.net.Uri uri = wakeappapplication.getChosenRingtone();

    if (uri != null)
        notification.sound = uri;

    notification.vibrate = VIBRATION_PATTERN;

    if (wakeappapplication.isRaiseVolume())
        ((AudioManager) context.getSystemService("audio")).adjustVolume(1,
                0);

    notificationmanager.notify("ProximityReceiver", 0, notification);


}}

解决方案

You should create a geofence and add it to google location services it will notify you (callback) when a user enters in a particular geofence or exits it.
