1、StringRequest用法
主要分为3步:
(1)、实例化一个RequestQueue对象
(2)、设置StringRequest对象参数,并将StringRequest对象加入RequestQueue队列
(3)、执行start()方法
public class StringActivity extends Activity { private TextView mTvShow; private RequestQueue requestQueue; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_string); initView(); } public void initView(){ mTvShow = (TextView) findViewById(R.id.tv_string); requestQueue = Volley.newRequestQueue(getBaseContext()); requestQueue.add(stringRequest); requestQueue.start(); } /** StringRequest请求,默认为GET*/ public StringRequest stringRequest = new StringRequest("http://www.baidu.com", new Listener<String>() { @Override public void onResponse(String response) { // TODO Auto-generated method stub Toast.makeText(getBaseContext(), response, Toast.LENGTH_SHORT).show(); } }, new ErrorListener(){ @Override public void onErrorResponse(VolleyError error) { // TODO Auto-generated method stub Log.e("StringRequest", error.toString()); } }); /** StringRequest的Post请求,但是需要重写匿名类getParams()*/ StringRequest stringRequest1 = new StringRequest(Method.POST, "http://www.baidu.com", new Listener<String>() { @Override public void onResponse(String response) { // TODO Auto-generated method stub mTvShow.setText(response); } }, new ErrorListener(){ @Override public void onErrorResponse(VolleyError error) { // TODO Auto-generated method stub Log.e("StringRequest", error.toString()); } }){ // 需要重写获取参数的函数 protected Map<String,String> getParams() throws AuthFailureError { Map<String, String> map = new HashMap<String, String>(); map.put("wd", "开始吗"); map.put("rsv_spt", "不开始啦"); return map; }; }; }
2、不要忘记加入网络访问权限
<uses-permission android:name="android.permission.INTERNET"/>
