ace布置小作业: 制作一个简单的电话号码归属地查询软件:JSON解析和Volly发送get请求

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);
    }
