重写parseNetworkResponse方法获取session：

RequestQueue mQueue  = Volley.newRequestQueue(getApplicationContext());;
            StringRequest stringRequest = new StringRequest(Request.Method.POST,url, new Response.Listener<String>() {
                @Override
                public void onResponse(String s) {
    
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError volleyError) {
                    //打印错误信息
                    Log.e("TAG", volleyError.getMessage(), volleyError);
                }
            }){
                @Override
                protected Response<String> parseNetworkResponse(NetworkResponse response) {
                    //获取session
                    new ConnectViaSession().getSession(response);
                    return super.parseNetworkResponse(response);
                }
                
            };

重写getHeaders方法发送session：

RequestQueue mQueue  = Volley.newRequestQueue(getApplicationContext());;
            StringRequest stringRequest = new StringRequest(Request.Method.POST,url, new Response.Listener<String>() {
                @Override
                public void onResponse(String s) {
    
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError volleyError) {
                    //打印错误信息
                    Log.e("TAG", volleyError.getMessage(), volleyError);
                }
            }){
                //设置session
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    String sesseionid = new ConnectViaSession().GetSession();
                    if (!sesseionid.equals("")) {
                        HashMap<String, String> headers = new HashMap<String, String>();
                        headers.put("cookie", sesseionid);
                        return headers;
                    }else {
                        return super.getHeaders();
                    }
                }
            };
            mQueue.add(stringRequest);

保持session：

package com.example.cuboo.myapplication.DataFromNetApi;
    
    import android.content.Context;
    import android.content.SharedPreferences;
    
    import com.android.volley.AuthFailureError;
    import com.android.volley.NetworkResponse;
    
    import java.util.HashMap;
    import java.util.Map;
    
    /**

     */
    
    public class ConnectViaSession {
    
        private static final String CooKie = "cookie_";
        private String mHeader;
        private Map<String, String> getHeader=new HashMap<String, String>();
        private String rawCookies;
        private String SesstionID;
        private Context context;
    
        public ConnectViaSession(Context context){
            this.context = context;
        }
        public void getSession(NetworkResponse response){
            //获取头部信息
            mHeader = response.headers.toString();
            //获取cookie头部信息
            getHeader = response.headers;
            rawCookies = getHeader.get("Set-Cookie");
            //;分隔获取sessionid
            SesstionID = rawCookies.substring(0,rawCookies.indexOf(";"));
            //使用SharedPreferences本地存储
            SaveSession(SesstionID);
        }
    
        //本地保存session
        public void SaveSession(String sessionid){
            SharedPreferences preferences =  context.
                    getSharedPreferences("ConnectViaSession.class", Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = preferences.edit();
            editor.putString(CooKie,sessionid);
            editor.commit();
        }
    
        //从本地获取session
        public String GetSession(){
            SharedPreferences preferences =  context
                    .getSharedPreferences("ConnectViaSession.class", Context.MODE_PRIVATE);
            return preferences.getString(CooKie,"");
        }
    }
