java - 如何在android中获取一个地方的时区？

Question

我在显示时区时遇到问题。我需要显示时区和时间，如“12/11/2014 11:45 IST”。我可以显示时间。但我无法显示区域是 PST、EST 或 IST。我该怎么做？谁能帮帮我？

我的源代码是错误的。

    Calendar c = Calendar.getInstance();
    year = c.get(Calendar.YEAR);
    month = c.get(Calendar.MONTH);
    day = c.get(Calendar.DAY_OF_MONTH);
    hour = c.get(Calendar.HOUR_OF_DAY);
    minute = c.get(Calendar.MINUTE);

 public static String TimezoneUrl = "https://maps.googleapis.com/maps/api/timezone/json?";

 API_KEY="Your API service key";
 newurl = TimezoneUrl+"location="+myLatitude+","
 +myLongitude+"&timestamp="+System.currentTimeMillis() / 1000 + "&key=" + API_KEY;
 response = makeServiceCall(url, ServiceHandler.GET);

 jsonResponse = new JSONObject(response);
 timesone = jsonResponse.getString("timeZoneName");


 for (int i = 0; i < timesone.length(); i++) {
        if (Character.isUpperCase(timesone.charAt(i))) {
            char c = timesone.charAt(i);
            timezone = timezone + c;
    }
 }

  public String makeServiceCall(String url, int method) {
    return this.makeServiceCall(url, method, null);
 }


 public String makeServiceCall(String url, int method,
    List<NameValuePair> params) {
 try {
    // http client
    DefaultHttpClient httpClient = new DefaultHttpClient();

    //httpClient.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "Custom user agent");
    HttpEntity httpEntity = null;
    HttpResponse httpResponse = null;

    // Checking http request method type
     if (method == GET) {
        // appending params to url
        if (params != null) {
            String paramString = URLEncodedUtils    .format(params, "utf-8");
            url += "?" + paramString;
        }
        HttpGet httpGet = new HttpGet(url);

        httpResponse = httpClient.execute(httpGet);

    }
    httpEntity = httpResponse.getEntity();
    response = EntityUtils.toString(httpEntity);

} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

return response;

}

结果将按照您期望的时区为您提供 IST。
