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：
