Android实战--解析稍复杂JSON数据DEMO

废话不多说，直接上代码，布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/mytext"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

.java:

package org.lxh.demo;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class Hello extends Activity {
    private TextView textView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); // 生命周期方法
        super.setContentView(R.layout.main); // 设置要使用的布局管理器
        this.textView = (TextView) findViewById(R.id.mytext);
        String str = "{"memberdata":[{"id":1,"name":"yayun","age":25},"
                + "{"id":2,"name":"qiangge","age":26}],"company":"NJUPT"}";
        StringBuffer buffer = new StringBuffer();
        Map<String, Object> resultMap = this.parseJson(str);
        buffer.append("单位名称：" + resultMap.get("company") + "n");
        @SuppressWarnings("unchecked")
        List<Map<String, Object>> all = (List<Map<String, Object>>) resultMap
                .get("memberdata");// 强制转换
        Iterator<Map<String, Object>> iter = all.iterator();
        while (iter.hasNext()) {
            Map<String, Object> map = iter.next();
            buffer.append("ID:" + map.get("id") + "姓名：" + map.get("name")
                    + "n");

        }
        this.textView.setText(buffer);

    }

    private Map<String, Object> parseJson(String data) {
        Map<String, Object> allMap = new HashMap<String, Object>();
        try {
            JSONObject allDataJsonObject = new JSONObject(data);
            allMap.put("company", allDataJsonObject.getString("company"));
            JSONArray array = allDataJsonObject.getJSONArray("memberdata");
            List<Map<String, Object>> all = new ArrayList<Map<String, Object>>();
            for (int i = 0; i < array.length(); i++) {
                Map<String, Object> map = new HashMap<String, Object>();
                JSONObject jsonObject = array.getJSONObject(i);
                map.put("id", jsonObject.getInt("id"));
                map.put("name", jsonObject.getString("name"));
                map.put("age", jsonObject.getInt("age"));
                all.add(map);
            }
            allMap.put("memberdata", all);// 将List<Map<String,
                                            // Object>>装入Map<String, Object>
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return allMap;
    }
}

运行实例效果如下：
