如何通过android java的可切换选项卡更改活动布局
在我的android应用程序中，我有两个如何通过android java的可切换选项卡更改活动布局,java,android,android-layout,tabs,Java,Android,Android Layout,Tabs,在我的android应用程序中，我有两个.xaml布局，如activity_1和activity_2，我想通过两个可切换选项卡更改这些布局的活动，因为在这之后我想添加更多选项卡：下面是我的活动： package com.example.hakslogin; import android.support.v4.view.PagerAdapter; import android.support.v4.view.PagerTitleStrip; import android.support.v4.vi
