[英]Display All Activities, Fragments in one Frame Layout using Android
我正在使用DrawerLayout
的Slider Menu
,它是主要的Activity。 它包含Frame Layout
。
主頁是Home,它將在Frame Layout
打開,並且是Fragment
。 一切正常。 現在,“主頁”包含2個按鈕,我將根據單擊的Button
打開不同的“ Activity
。
它會打開新的Activity
但我想在其中有Home的同一Frame Layout中打開它,以便可以在All Activity
擴展Slider菜單。
如何實施呢?
