问题描述

我的活动中有两个按钮(button1，button2). botton1是'Enabled'(true)，而另一个不是.

I have two buttons(button1, button2) in my activty. botton1 is 'Enabled'(true) , while the other one isn't.

当我单击button1时，button2变为启用".我想在此状态下记录此活动，以供我的应用程序下次使用.

When I click on button1, button2 becomes 'Enabled'. I want to record this activity in this state for the next utilization of my application.

推荐答案

您可以将状态保存在sharedPrefrences中，请尝试

You can save state in sharedPrefrences, try this

SharedPreferences prefs = getSharedPreferences("Your preference name here", MODE_PRIVATE) 


b1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                b2.setEnabled(true);
                prefs.edit().putBoolean("b2enabled", true).commit();//saving State here
            }
        });

现在您要在其中使用此状态的地方，只需简单地获取状态即可.

And now where you want to use this state simple get the state as.

Boolean b2state= prefs.getBoolean("b2enabled", false); //false is the default value

如果要启用或禁用结果按钮

And if you want to enable or disable button on result do

if (b2state){
b2.enabled(true);
}
else{
b2.enabled(false);
}
