导读：自定义GSON类 1 public class GsonRequestT extends RequestT { 2 private final Gson mGson = new Gson(); 3 final ClassT mClazz; 4 final ListenerT mListener; 5 final MapString,String mHeaders; 6 7 public GsonRequest(String url,ClassT clazz,List

自定义GSON类

 
    
  
public class GsonRequest<T> extends Request<T> {
   private final Gson mGson = new Gson();
   final Class<T> mClazz;
   final Listener<T> mListener;
   final Map<String,String> mHeaders;

   public GsonRequest(String url,Class<T> clazz,Listener<T> listener,ErrorListener errorListener) {
       this(Method.GET,url,clazz,null,listener,errorListener);
   }

   public GsonRequest(int method,String url,Map<String,String> headers,12             Listener<T> listener,128); line-height:1.5!important">13         super(method,128); line-height:1.5!important">14         this.mClazz = clazz;
       this.mHeaders = headers;
       this.mListener = listener;
   }

   @Override
   public Map<String,String> getHeaders() throws AuthFailureError {
       return mHeaders != null ? mHeaders : super.getHeaders();
   }

   @Override
   protected void deliverResponse(T response) {
       mListener.onResponse(response);
   }

   @Override
   protected Response<T> parseNetworkResponse(NetworkResponse response) {
       try {
           String json = new String(response.data,HttpHeaderParser.parseCharset(response.headers));
           return Response.success(mGson.fromJson(json,mClazz),128); line-height:1.5!important">34                     HttpHeaderParser.parseCacheHeaders(response));
       } catch (UnsupportedEncodingException e) {
           return Response.error(new ParseError(e));
       } catch (JsonSyntaxException e) {
           39         }
   }
} 
    
  

自定义FastJson类

class FastJsonRequest<T> extends Request<T> { 5 6 public FastJsonRequest(String url,128); line-height:1.5!important"> 7 8 } 9 10 public FastJsonRequest(11 Listener<T> listener,128); line-height:1.5!important">12 16 } 17 18 @Override 19 20 21 } 22 23 @Override 24 25 mListener.onResponse(response); 26 } 27 28 @Override 29 30 31 String json = 32 return Response.success(JSON.parSEObject(json,128); line-height:1.5!important">33 HttpHeaderParser.parseCacheHeaders(response)); 34 } 35 36 } 37 } 38 }

class MainActivity extends Activity { private Context context; private String url="http://www.weather.com.cn/data/sk/101010100.html"; private TextView text; 5 6 @Override void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); 9 setContentView(R.layout.activity_main); 10 context=this; 11 text=(TextView)this.findViewById(R.id.txttitle); 12 RequestQueue mQueue = Volley.newRequestQueue(context); 13 FastJsonRequest<Weather> fastJson=new FastJsonRequest<Weather>(url,Weather.class,128); line-height:1.5!important">14 new Response.Listener<Weather>() { 15 16 @Override 17 void onResponse(Weather weather) { 18 // TODO Auto-generated method stub 19 WeatherInfo weatherInfo = weather.getWeatherinfo(); 20 text.setText(weatherInfo.getCity()); 21 } 22 },255); line-height:1.5!important">new Response.ErrorListener() { 24 @Override 25 void onErrorResponse(VolleyError arg0) { 26 27 28 } 29 }); 30 mQueue.add(fastJson); 31 32 GsonRequest<Weather> gsonRequest=new GsonRequest<Weather>(url,128); line-height:1.5!important">33 34 35 @Override 36 37 38 WeatherInfo weatherInfo = weather.getWeatherinfo(); 39 text.setText(text.getText()+weatherInfo.getTime()); 40 } 41 },128); line-height:1.5!important">42 43 @Override 44 45 46 47 } 48 }); 49 mQueue.add(gsonRequest); 50 51 52 } 53 }

Model类

class Weather { private WeatherInfo weatherinfo; 3 public WeatherInfo getWeatherinfo() { 5 return weatherinfo; 6 } 7 8 void setWeatherinfo(WeatherInfo weatherinfo) { 9 this.weatherinfo = weatherinfo; 10 } 11 }

class WeatherInfo { private String city; private String temp; 5 private String time; public String getCity() { return city; 11 12 void setCity(String city) { this.city = city; 14 } 15 16 public String getTemp() { 17 return temp; 18 } 19 void setTemp(String temp) { this.temp = temp; 22 } 23 public String getTime() { 25 return time; 26 } 27 28 void setTime(String time) { 29 this.time = time; 30 } 31 }
