使用Android studio在build.gradle添加以下信息就可以获取支持库,当然了,如果你没有下载到该支持库会提示你下载。compile 'com.mcxiaoke.volley:library:1.0.19'
在一个Application中创建一个请求队列,调用通过((Myapp) getApplication()).requestQueue.add(request);public RequestQueue requestQueue;@Overridepublic void onCreate() { super.onCreate(); requestQueue = Volley.newRequestQueue(getApplicationContext());}有多种请求队列,这里就不再叙述,主要写一个自定义的请求队列public class ObjectRequestextends Request { private final Response.Listener surcess; private final Class cls; public ObjectRequest(int method, String url, Response.ErrorListener listener, Response.Listener surcess, Class cls) { super(method, url, listener); this.surcess = surcess; this.cls = cls; } @Override protected Response parseNetworkResponse(NetworkResponse response) { String result = null; try { //设置响应后返回值的编码,与服务器请求头的一致 result = new String(response.data, HttpHeaderParser.parseCharset(response.headers)); //解析 Gson gson = new Gson(); T t = gson.fromJson(result, cls); return Response.success(t, HttpHeaderParser.parseCacheHeaders(response)); } catch (UnsupportedEncodingException e) { return Response.error(new VolleyError(e)); } } /** * @param response */ @Override protected void deliverResponse(Object response) { if (surcess != null) {//Response.Listener 响应的监听为空。。 surcess.onResponse(response); } }}--Zero
