最近项目中有些人使用xml存储了一些区域级联信息 (类型于山东 -(济南市,青岛市(崂山,四方)))这样的信息.使用 的是吧xml数据存储到sharepreference 感觉不是很好,费力不讨好

于是想到了json

确实,有些东西不必用到数据库 使用json和xml就可以了.个人偏好json

package com.example.testjsonandxml;

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

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

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		String json = getString(R.string.json);

		DataStoreUtil.put(this,"json",json);

		JSONObject jsonObject;
		try {
			jsonObject = new JSONObject(json);
			TextView textView = new TextView(this);
			textView.setText(jsonObject.getString("name"));
			textView.append(jsonObject.getString("price"));

			textView.append("来自SharePreference:"+new JSONObject(DataStoreUtil.getString(
					MainActivity.this,"json")).getString("mktprice"));
			setContentView(textView);
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main,menu);
		return true;
	}

}
