Android 解析服务器json数据

首先看下服务器数据

再看看运行效果

首先是布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main"    android:layout_width="match_parent" android:layout_height="match_parent"    tools:context="com.zking.mygetjson.MainActivity">    <ListView        android:layout_width="match_parent"        android:layout_height="match_parent"        android:id="@android:id/list"></ListView></LinearLayout>

Activity代码

package com.zking.mygetjson;import android.app.ListActivity;import android.net.Uri;import android.os.AsyncTask;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.LinearLayout;import android.widget.TextView;import com.google.gson.Gson;import com.google.gson.reflect.TypeToken;import com.zking.entity.BlogsType;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.StringBufferInputStream;import java.net.HttpURLConnection;import java.net.MalformedURLException;import java.net.URL;import java.util.ArrayList;import java.util.List;import java.util.StringTokenizer;public class MainActivity extends ListActivity {    private List<BlogsType> blogsTypes = new ArrayList<>();    private MyAdapter myAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        myAdapter = new MyAdapter();        setListAdapter(myAdapter);        new MyTask().execute();    }    private class MyTask extends AsyncTask{        @Override        protected Object doInBackground(Object[] params) {            try {                URL url = new URL(getString(R.string.server_name) + "/blogstype/getblogstype");                HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();                httpURLConnection.setRequestMethod("GET");                httpURLConnection.setConnectTimeout(5000);                InputStream is = httpURLConnection.getInputStream();                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is,"utf-8"));                StringBuffer buffer = new StringBuffer();                String s = null;                while ((s=bufferedReader.readLine())!=null){                    buffer.append(s);                }                blogsTypes = new Gson().fromJson(buffer.toString(),new TypeToken<List<BlogsType>>(){}.getType());            } catch (MalformedURLException e) {                e.printStackTrace();            } catch (IOException e) {                e.printStackTrace();            }            return null;        }        @Override        protected void onPostExecute(Object o) {            super.onPostExecute(o);            myAdapter.notifyDataSetChanged();        }    }    private class MyAdapter extends BaseAdapter{        @Override        public int getCount() {            return blogsTypes.size();        }        @Override        public Object getItem(int position) {            return blogsTypes.get(position);        }        @Override        public long getItemId(int position) {            return position;        }        @Override        public View getView(int position, View convertView, ViewGroup parent) {            LinearLayout linearLayout = new LinearLayout(MainActivity.this);            TextView textView = new TextView(MainActivity.this);            TextView textView1 = new TextView(MainActivity.this);            textView.setText(blogsTypes.get(position).getBtid()+"");            textView1.setText(blogsTypes.get(position).getBtname());            linearLayout.addView(textView);            linearLayout.addView(textView1);            return linearLayout;        }    }}

实体类

package com.zking.entity;/** * Created by Administrator on 2017/2/25. */public class BlogsType {    private int btid;    private String btname;    private String btintroduce;    private String btimage;    public int getBtid() {        return btid;    }    public void setBtid(int btid) {        this.btid = btid;    }    public String getBtname() {        return btname;    }    public void setBtname(String btname) {        this.btname = btname;    }    public String getBtintroduce() {        return btintroduce;    }    public void setBtintroduce(String btintroduce) {        this.btintroduce = btintroduce;    }    public String getBtimage() {        return btimage;    }    public void setBtimage(String btimage) {        this.btimage = btimage;    }}
