SharedPreferences &布尔值 [英] SharedPreferences & boolean

问题描述

我试图在执行方法时将isPhysicalTheftEnabled"设置为 false，但这似乎不起作用.有人知道吗?

I'm trying to set the "isPhysicalTheftEnabled" to false when a method is executed, but this doesn't seem to work. Anyone have any idea?

        SharedPreferences sp = getSharedPreferences("isPhysicalTheftEnabled", MODE_WORLD_READABLE);
        SharedPreferences.Editor ed = sp.edit();
        ed.putBoolean("isPhysicalTheftEnabled", false);

推荐答案

尝试添加 ed.commit().

即:

SharedPreferences sp = getSharedPreferences("isPhysicalTheftEnabled", MODE_WORLD_READABLE);
SharedPreferences.Editor ed = sp.edit();
ed.putBoolean("isPhysicalTheftEnabled", false);
ed.commit();

SharedPreferences.Editor要求您提交您在 SharedPreferences 中所做的任何更改，以便应用更改.

SharedPreferences.Editors require that you commit anything you change in your SharedPreferences for the changes to apply.

关于您对 Ankit 回答的评论:

要根据保存到 SharedPreferences 的布尔值设置 CheckBox 的选中属性，您需要类似以下内容:

To set the checked property of your CheckBox based on the value of the boolean you saved to SharedPreferences, you need something like:

SharedPreferences sp = getSharedPreferences("isPhysicalTheftEnabled", MODE_WORLD_READABLE);
myCheckBox.setChecked(sp.getBoolean("isPhysicsTheftEnabled", [true/false]);

.. 为 .getBoolean() 的 def_value 选择 true 或 false (如果 SharedPreferences 找不到布尔值).

.. in which you pick either true or false for the def_value of .getBoolean() (if the SharedPreferences can't find the boolean).
