 <span style="font-size:18px;">1.添加全局myapplication:</span><pre name="code" class="java">public class MyApplication extends Application {
    public  static RequestQueue queue;
    @Override
    public void onCreate() {
        super.onCreate();
        queue= Volley.newRequestQueue(getApplicationContext());
    }

    public  static  RequestQueue  getHttpQueue(){
        return  queue;
    }
}

2.实现请求：

   private void Volley_Post() {
         String url="api接口";

        StringRequest  request=new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String s) {

                try {
                    try {
                        JSONObject  object=new JSONObject(s);
                      String reuslt=  object.getString("return");
                        Toast.makeText(RegisterActivity.this, reuslt, Toast.LENGTH_SHORT).show();

                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
                System.out.println(s);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {

            }
        }){
            @Override
            protected Map<String, String> getParams() throws AuthFailureError {
                HashMap<String,String> map=new HashMap<String,String>();
                map.put("username", etusername.getText().toString());
                map.put("password", etpwd.getText().toString());
                map.put("email", etemail.getText().toString());
                map.put("mobile", etphone.getText().toString());
                return map;
            }
        };
        MyApplication.getHttpQueue().add(request);      //加入到请求队列
        request.setTag("regPost");

    }
}
