建立单独的 SharedPreferences 类文件

package com.example.myapplication.Preferences;

import android.content.Context; import android.content.SharedPreferences;

public class MyData {

private Context context; public MyData(Context context) { this.context = context; } public void save(){ SharedPreferences shp = context.getSharedPreferences("my_data",Context.MODE_PRIVATE); SharedPreferences.Editor edit = shp.edit(); edit.putString("name","张某"); edit.putInt("age",40); edit.apply(); } public String load(){ SharedPreferences shp = context.getSharedPreferences("my_data",Context.MODE_PRIVATE); return shp.getString("name","傻瓜"); }

}
