Question

我想将英里换成米？和其他单位指标？我尝试了很多变种来改变价值，但它没有帮助我，请有人能做到吗？如果有必要我可以分享我的所有代码，对不起我的英语。

我的代码请帮忙。

Double speedInMilesPerHour = location.getSpeed()* 3.6; //inMeters
    requestParams.put("speed",  Integer.toString(speedInMilesPerHour.intValue()));

    try {
        requestParams.put("date", URLEncoder.encode(dateFormat.format(date), "UTF-8"));
    } catch (UnsupportedEncodingException e) {}

    requestParams.put("locationmethod", location.getProvider());

    if (totalDistanceInMeters > 0) {
        requestParams.put("distance", String.format("%.1f", totalDistanceInMeters / 1609)); // in miles,
    } else {
        requestParams.put("distance", "0.0"); // in miles
    }

    requestParams.put("username", sharedPreferences.getString("userName", ""));
    requestParams.put("phonenumber", sharedPreferences.getString("appID", "")); // uuid
    requestParams.put("sessionid", sharedPreferences.getString("sessionID", "")); // uuid

    Double accuracyInFeet = location.getAccuracy()* 3.28;
    requestParams.put("accuracy",  Integer.toString(accuracyInFeet.intValue()));

    Double altitudeInFeet = location.getAltitude() * 3.28;
    requestParams.put("extrainfo",  Integer.toString(altitudeInFeet.intValue()));

您可以编写适用于双打的简单转换方法：

    public static double metersToMiles(double meters) {
        return meters / 1609.3440057765;
    }

    public static double milesToMeters(double miles) {
        return 0.0006213711 * miles;
    }
