getSharedPreferences简单实用

SharedPreferences user = getSharedPreferences("User", MODE_PRIVATE);
        int anInt = user.getInt("selectcolor", 0);
        if (anInt != 0) {
            rlBackground.setBackgroundColor(anInt);
        }

//接收值

 SharedPreferences user = getSharedPreferences("User", MODE_PRIVATE);
                SharedPreferences.Editor edit = user.edit();
                edit.putInt("selectcolor", "保存的数据");
                edit.commit();

//保存值
