SharedPreFerences如何存取以及读取

SharedPreFerences 储存数据分为四步
1.新建sharedPreFerences对象
2.通过sharedPreFerences.editor()创建editor对象
3.储存数据，通过editor.putString()、editor.putInt()方法储存，括号内是以键值对的形式存在例如editor.putString(“name”,”小明”)
4.提交数据 editor.commit();
附上一段简单的代码👇

SharedPreferences sharedPreferences=getSharedPreferences("sp",MODE_PRIVATE);
        SharedPreferences.Editor editor=sharedPreferences.edit();
        editor.putString("name","张三");        editor.commit();

读取sp

SharedPreferences sharedPreferences=getSharedPreferences("sp",MODE_PRIVATE);
SharedPreferences.Editoreditor=sh aredPreferences.edit();editor.putString("name","张三");
editor.commit();sp_tv.setText(sharedPreferences.getString("name",""));
