專案實戰：一、json解析資料的框架
這是json解析資料的工具類 到時候直接呼叫這個工具類 進行解析資料
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.util.Log;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
/**

public class NetWorkUtils {

try {

//打開了連線
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
int responseCode = urlConnection.getResponseCode();
