机器人 - 如何让每10米位置更新？ [英] android - how to get location update on every 10 meters?

问题描述

在我的应用程序必须对各10米的速度运行更新的具体数据。
对于读音字使用的LocationManager得到更新，但我没有得到正确的答案。

我用下面的code：还增加了权限粗，细，互联网。

  locationManager.requestLocationUpdates（getProviderName（），10000，
            10，LocationListener的）;私人字符串getProviderName（）{
    的LocationManager的LocationManager =（的LocationManager）本
            .getSystemService（Context.LOCATION_SERVICE）;    标准标准=新标准（）;
    criteria.setPowerRequirement（Criteria.POWER_LOW）;
    // criteria.setAccuracy（Criteria.ACCURACY_FINE）;
    criteria.setSpeed​​Required（真）;
    criteria.setAltitudeRequired（真）;
    criteria.setBearingRequired（真）;
    criteria.setCostAllowed（假）;
    criteria.setAccuracy（Criteria.ACCURACY_MEDIUM）;
    criteria.setSpeed​​Accuracy（Criteria.ACCURACY_MEDIUM）;
    criteria.setBearingAccuracy（Criteria.ACCURACY_MEDIUM）;    返回locationManager.getBestProvider（标准，真正的）;
}
 

这是条件说的LocationManager每10秒更新覆盖或不10米？我对吗？

解决方案

  //的最小距离改变米的更新
私有静态最后长MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; //10米//毫秒更新之间的最短时间
私有静态最后长MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1分钟locationManager.requestLocationUpdates（
                            LocationManager.NETWORK_PROVIDER，
                            MIN_TIME_BW_UPDATES，
                            MIN_DISTANCE_CHANGE_FOR_UPDATES，这一点）;
 

in my application i have to update specific data on travelling of each 10 meters. For that i m using LocationManager to get updates , but i am not getting correct answers.

I have used following code : Also added Permissions coarse, fine , internet .

locationManager.requestLocationUpdates(getProviderName(), 10000,
            10, locationListener);

private String getProviderName() {
    LocationManager locationManager = (LocationManager) this
            .getSystemService(Context.LOCATION_SERVICE);

    Criteria criteria = new Criteria();
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    // criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setSpeedRequired(true);
    criteria.setAltitudeRequired(true);
    criteria.setBearingRequired(true);
    criteria.setCostAllowed(false);
    criteria.setAccuracy(Criteria.ACCURACY_MEDIUM);
    criteria.setSpeedAccuracy(Criteria.ACCURACY_MEDIUM);
    criteria.setBearingAccuracy(Criteria.ACCURACY_MEDIUM);

    return locationManager.getBestProvider(criteria, true);
}

Is this condition says LocationManager to update on every 10 seconds for 10 meters covered or not? am i right?

解决方案

// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters

// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute

locationManager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER,
                            MIN_TIME_BW_UPDATES,
                            MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
