Android轉換不起作用

Question

我想在TitleScreenActivity和MainActivity中離開時在android中播放transitionSet。問題是：它只播放淡入淡出的動畫，但不播放其他兩張幻燈片。

這裏是我的代碼：

transition_menu.xml

<?xml version="1.0" encoding="utf-8"?> 
     <transitionSet xmlns:android="http://schemas.android.com/apk/res/android" 
      android:transitionOrdering="together" 
      android:duration="500" 
      > 
      <fade xmlns:android="http://schemas.android.com/apk/res/android"> 
       <targets> 
        <target android:excludeId="@android:id/statusBarBackground"/> 
        <target android:excludeId="@android:id/navigationBarBackground"/> 
       </targets> 
      </fade> 

      <slide android:slideEdge="top"> 
       <targets> 
        <target android:targetId="@id/toolbar"/> 
       </targets> 
      </slide> 

      <slide android:slideEdge="bottom"> 
       <targets> 
        <target android:targetId="@id/bottomSheet"/> 
       </targets> 
      </slide> 
     </transitionSet>

Answer 1

我實際上已經開始工作了。我只是從我的MainActivity的CoordinatorLayout中刪除了標籤

android:background="@color/colorPrimary" 

。我不知道爲什麼，但它現在起作用。

Answer 2

爲了使用窗口活動轉換，您必須使用windowActivityTransitions標誌。您也可以從Theme.AppCompat繼承API 21+繼承自Theme.Material。

您一直在使用的標誌windowContentTransitions告訴系統您打算使用TransitionManager在場景之間切換。
