Android-Volley详解

（一）网络数据请求

　　①使用GET的请求方式的第一种方法

private void Volley_Get() {
        String url = "http://112.124.118.133:9065/ssgApp/getClassifyone";
        StringRequest request = new StringRequest(Method.GET, url,
                new Listener<String>() {

                    @Override
                    public void onResponse(String arg0) {
                        Toast.makeText(MainActivity.this, arg0,
                                Toast.LENGTH_LONG).show();

                    }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError arg0) {
                        Toast.makeText(MainActivity.this, arg0.toString(),
                                Toast.LENGTH_LONG).show();

                    }
                });
　　//请求对象设置setTag标签
        request.setTag("abcGet");
        MyApplication.getHttpQueue().add(request);

    }

 

 

②使用GET请求方式的第二种方法

private void Volley_Get() {
        String url = "http://112.124.118.133:9065/ssgApp/getClassifyone";
　　　　JsonObjectRequest request = new JsonObjectRequest(Method.GET, url, url,
　　　　　　　　　　　　new Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject arg0) {
                        Toast.makeText(MainActivity.this, arg0.toString(),
                                Toast.LENGTH_LONG).show();

                    }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError arg0) {
                        Toast.makeText(MainActivity.this, arg0.toString(),
                                Toast.LENGTH_LONG).show();

                    }
                });
        request.setTag("abcGet");
        MyApplication.getHttpQueue().add(request);

    }
