SharedPreferences类提供了一种简单的文件存储功能，像程序的配置文件可以通过它来实现。

源代码：

    package com.test.sharedpreferences;

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.TextView;

public class test_sharedpreferences extends Activity 
{
	SharedPreferences file;
	SharedPreferences.Editor editor;
	TextView text;
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        //获得配置文件
        file = getSharedPreferences("test_config", 0);
        editor = file.edit();
        
        //写入配置：Id:10000 Name:Jdh
        editor.putInt("Id", 10000);
        editor.putString("Name", "Jdh");
        editor.commit();
        
        //读取配置
        int id = 0;
        id = file.getInt("Id", 0);
        String str;
        str = file.getString("Name", null);
        
        text = (TextView)findViewById(R.id.textView1);
        text.setText("Id:" + id + " Name:" + str);  
    }
}
