SharedPreferences使用一

main.xml

<?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:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

</LinearLayout>

ActivityMain

package com.android;

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

public class ActivityMain extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        //保存数据到SharedPreferences
        SharedPreferences sharedPreferences = getSharedPreferences("test", Context.MODE_WORLD_READABLE);
        //获取编辑器对象
        Editor editor = sharedPreferences.edit();
        editor.putString("name", "android");
        editor.putInt("age", 2);
        //提交修改
        editor.commit();
        
        //获取SharedPreferences中保存的数据
        //SharedPreferences sharedPreferences = getSharedPreferences("test", Context.MODE_PRIVATE);
        //getString()第二个参数为缺省值，如果preference中不存在该key，将返回缺省值
        String name = sharedPreferences.getString("name", "");
        int age = sharedPreferences.getInt("age", 1);
        Toast.makeText(this, "name:"+name+",age:"+age, Toast.LENGTH_LONG).show();
        
        
        
        
        
    }
}

1.Context.MODE_PRIVATE指定该SharedPreferences数据只能被本应用程序读写

2.Context.MODE_WORLD_READABLE指定该SharedPreferences数据能被其他程序读，但不能写
3.Context.MODE_WORLD_WRITEABLE指定该SharedPrefernces数据能被其他程序读写
