Answer 1

您可以在显示权限对话框之前检查位置权限和位置服务。

检查位置权限

public static boolean isLocationPermissionAvailable(Context context) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
        return true;
    }

    return (context.checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
}

检查位置服务是否启用

public static boolean isLocationEnabled(Context context) {
    // Check if Current Device's SDK Version is Kitkat (Android 4.4 = API 19) & above
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        int locationMode = 0;
        try {
            locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
        } catch (Settings.SettingNotFoundException e) {
            e.printStackTrace();
        }

        return locationMode != Settings.Secure.LOCATION_MODE_OFF;

    } else {
        LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) &&
                locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
    }
}
