如何检查位置是否在 API 18 及更低版本上处于打开状态且优先级高

Question

试过这个：

String locationProviders = Settings.Secure.getString(getActivity().getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
Log.d(TAG_MAP, locationProviders);

输出为：GPS，网络

API 18 及更低版本的手机是否没有HIGH_ACCURACY优先级？

Answer 1

我假设您想知道使用 API 级别 19 中已弃用的 Settings.Secure.LOCATION_PROVIDERS_ALLOWED 与使用 API 级别 19 中引入的 Settings.Secure.LOCATION_MODE 有何不同。

使用 Settings.Secure.LOCATION_MODE ，您有这些值（您可能已经知道这一点）：

LOCATION_MODE_HIGH_ACCURACY， LOCATION_MODE_SENSORS_ONLY， LOCATION_MODE_BATTERY_SAVING或LOCATION_MODE_OFF

您可以通过以下方式将这些值映射到Settings.Secure.LOCATION_PROVIDERS_ALLOWED：

LOCATION_MODE_HIGH_ACCURACY ： "GPS，网络"

LOCATION_MODE_SENSORS_ONLY ： "全球定位系统"

LOCATION_MODE_BATTERY_SAVING："网络"

LOCATION_MODE_OFF ： "

请注意，在代码中，最好引用常量LocationManager.GPS_PROVIDER和LocationManager.NETWORK_PROVIDER，而不仅仅是"gps"和"network"。

使用此答案作为参考，您可以执行以下操作：

public static int getLocationMode(Context context) {
    int locationMode = 0;
    String locationProviders;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        try {
            locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
        } catch (SettingNotFoundException e) {
            e.printStackTrace();
        }

    } else {
        locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if (TextUtils.isEmpty(locationProviders)) {
          locationMode = Settings.Secure.LOCATION_MODE_OFF;
        }
        else if (locationProviders.contains(LocationManager.GPS_PROVIDER) && locationProviders.contains(LocationManager.NETWORK_PROVIDER)) {
          locationMode = Settings.Secure.LOCATION_MODE_HIGH_ACCURACY;
        }
        else if (locationProviders.contains(LocationManager.GPS_PROVIDER)) {
           locationMode = Settings.Secure.LOCATION_MODE_SENSORS_ONLY;
        }
        else if (locationProviders.contains(LocationManager.NETWORK_PROVIDER)) {
           locationMode = Settings.Secure.LOCATION_MODE_BATTERY_SAVING;
        }
    }
    return locationMode;
} 

Answer 2

您可以使用

此功能。我在 API 21 和 API 16 上进行了测试

public static boolean checkHighAccuracyLocationMode(Context context) {
    int locationMode = 0;
    String locationProviders;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
        //Equal or higher than API 19/KitKat
        try {
            locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
            if (locationMode == Settings.Secure.LOCATION_MODE_HIGH_ACCURACY){
                return true;
            }
        } catch (Settings.SettingNotFoundException e) {
            e.printStackTrace();
        }
    }else{
        //Lower than API 19
        locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
        if (locationProviders.contains(LocationManager.GPS_PROVIDER) && locationProviders.contains(LocationManager.NETWORK_PROVIDER)){
            return true;
        }
    }
    return false;
}

请记住，HIGH_ACCURACY模式意味着用户启用了 GPS 和网络提供商。否则，此函数将返回 false。

Answer 3

试试这个Settings.Secure.LOCATION_MODE

String gpsStatus = android.provider.Settings.Secure.getString(mContext.getContentResolver(), Settings.Secure.LOCATION_MODE);

您可以使用此检查

if (Build.VERSION.SDK_INT >= 21 &&
        ActivityCompat.checkSelfPermission(mContext, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
        ActivityCompat.checkSelfPermission(mContext, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    Log.e("gpsStatus", "LOCATION PERMISSION NOT GRANTED");
} else {
    Log.d("gpsStatus", "LOCATION PERMISSION GRANTED");
    if (gpsStatus.indexOf("gps", 0) < 3) {
        Log.d("gpsCheck", "DEVICE LOCATION PERMISSION IS GRANTED");
     
    } else {
        Log.e("gpsCheck", "DEVICE LOCATION PERMISSION NOT GRANTED");
    }
}
