大概就这个样子

用到JSON解析和Volly发送Get请求两个知识点

关于Volly的用法请看我的这篇:

JSON解析请看

http://www.cnblogs.com/AceIsSunshineRain/p/5178305.html

JSON数据是这样

{
"resultcode":"200",
"reason":"Return Successd!",
"result":{
"province":"河南",
"city":"安阳",
"areacode":"0372",
"zip":"455000",
"company":"中国移动",
"card":"移动全球通卡"
},
"error_code":0
}

下面看代码

MyApplication:

public class MyApplication extends Application { private static RequestQueue mQueue; @Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
mQueue = Volley.newRequestQueue(getApplicationContext());
} public static RequestQueue getRequestQueue(){
return mQueue;
}}

MainActivity

public class MainActivity extends Activity { private TextView textView;
private Button button;
private EditText editText; @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.tv_show);
button = (Button) findViewById(R.id.button1);
editText = (EditText) findViewById(R.id.ed_query); }
public void start(View view) { sendStringGet();
} public void sendStringGet() {
String number = editText.getText().toString();
String url = "http://apis.juhe.cn/mobile/get?phone=" + number + "&key=f64ff5c4c517da17761f112d6c3c0da0";
StringRequest mRequest = new StringRequest(Method.GET, url, new Listener<String>() { private String province;
private String city;
private String company;
private String card; @Override
public void onResponse(String arg0) {
// TODO Auto-generated method stub
JSONObject jsonObject; try { jsonObject = new JSONObject(arg0);
Log.d("ace", arg0);
String resultcode =jsonObject.getString("resultcode");
Log.d("ace", resultcode);
String reason =jsonObject.getString("reason");
int error_code =jsonObject.getInt("error_code"); if (error_code == 0) {
JSONObject result = jsonObject.getJSONObject("result");
province = result.getString("province");
city = result.getString("city");
company = result.getString("company");
card = result.getString("card"); textView.setText("您输入的手机号码归属地是:" + "\n" + province + city + company + card + "\n" + "查询成功");
}else if (error_code == 201102){
textView.setText("您输入的号码有误");
}else if (error_code == 201101){
textView.setText("请输入号码亲~");
}else if (error_code == 201103){
textView.setText("亲~ace查不到啊!"); } } catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} }
}, new Response.ErrorListener(){ @Override
public void onErrorResponse(VolleyError arg0) {
Toast.makeText(MainActivity.this, arg0.toString(), Toast.LENGTH_LONG).show();
textView.setText(arg0.toString());
} });
MyApplication.getRequestQueue().add(mRequest);
}}
