当我尝试传递纬度和对数时，我收到了这个 ArrayIndexOutOfBoundsException

private String getId(String facebookUser,String lat, String expiryMinute, String messageId, String message, String referenceKey, String placeId) {

        lang = Utils.formatDouble(Constants.searchLocation.getLongitude());
        lat = Utils.formatDouble(Constants.searchLocation.getLatitude());
        String traceId = null;
        HttpClient client = new HttpClient();
        PostMethod post = null;
        try {

            NameValuePair[] params = null;
            NameValuePair param = new NameValuePair();

            if(Constants.isMessageForPosting){
                params = new NameValuePair[6];
                param.setName("gadget");
                param.setValue("gettraceid");
                params[0] = param;

                if(messageId == null || messageId.trim().isEmpty()){
                    messageId = "1";
                }
            }else{
                params = new NameValuePair[8];
                param.setName("gadget");
                param.setValue("getrequestid");
                params[0] = param;
                if(messageId == null || messageId.trim().isEmpty()){
                    messageId = "2";
                }
            }

            if(expiryMinute == null || expiryMinute.trim().isEmpty()){
                expiryMinute = "0";
            }

            param = new NameValuePair();
            param.setName("fbuserid");
            param.setValue(facebookUser);
            params[1] = param;


            param = new NameValuePair();
            param.setName("userid");
            param.setValue(Constants.USERID);
            params[2] = param;

            param.setName("expiryminute");
            param.setValue(expiryMinute);
            params[3] = param;

            param.setName("msgid");
            param.setValue(messageId);
            params[4] = param;

            param = new NameValuePair();
            param.setName("msg");
            param.setValue(message);
            params[5] = param;

            param = new NameValuePair();
            param.setName("lat");
            param.setValue(lat);
            params[9] = param;

            param = new NameValuePair();
            param.setName("lang");
            param.setValue(lang);
            params[10] = param;
        */  
            if(!Constants.isMessageForPosting){
                param = new NameValuePair();
                param.setName("referencekey");
                param.setValue(referenceKey);
                params[6] = param;

                param = new NameValuePair();
                param.setName("placeid");
                param.setValue(placeId);
                params[7] = param;
            }

            post.setQueryString(params);
        int statusCode = client.executeMethod(post);
            traceId = post.getResponseBodyAsString();

        } catch (Exception e) {
            Log.e(TAG, "For Facebook Trace Id:", e);

        } finally {
            post.releaseConnection();
            post = null;
        }
        return Id;
    }

问题是您使用 6 个元素或 8 个元素声明 params 变量。但稍后您正在访问第 8 和第 9 个元素，这是错误的。

解决方案：

您应该使用 10 个元素的静态数组大小或使用 ArrayList 类。
