分享圖標（矢量）顯示設計，但不是在應用程序

Question

我已經使用矢量在卡片視圖中創建共享圖標。

在HolderClass

class CommasHolder extends RecyclerView.ViewHolder{ 
SimpleDraweeView commasImage; 
ImageButton shareButton; 

public CommasHolder(View cardView){ 
    super(cardView); 
    commasImage = (SimpleDraweeView) cardView.findViewById(R.id.cardview_image); 
    shareButton = (ImageButton) cardView.findViewById(R.id.share_button); 
} 
} 

佈局

<ImageButton 
     android:id="@+id/share_button" 
     android:layout_width="30dp" 
     android:layout_height="30dp" 
     android:layout_marginRight="10dp" 
     android:layout_gravity="bottom|end" 
     card_view:srcCompat="@drawable/ic_share_black_24dp"/> 

實現矢量

<vector xmlns:android="http://schemas.android.com/apk/res/android" 
    android:width="24dp" 
    android:height="24dp" 
    android:viewportWidth="24.0" 
    android:viewportHeight="24.0"> 
<path 
    android:fillColor="#FF000000" 
    android:pathData="M18,16.08c-0.76,0 -1.44,0.3 -1.96,0.77L8.91,12.7c0.05,-0.23 0.09,-0.46 0.09,-0.7s-0.04,-0.47 -0.09,-0.7l7.05,-4.11c0.54,0.5 1.25,0.81 2.04,0.81 1.66,0 3,-1.34 3,-3s-1.34,-3 -3,-3 -3,1.34 -3,3c0,0.24 0.04,0.47 0.09,0.7L8.04,9.81C7.5,9.31 6.79,9 6,9c-1.66,0 -3,1.34 -3,3s1.34,3 3,3c0.79,0 1.5,-0.31 2.04,-0.81l7.12,4.16c-0.05,0.21 -0.08,0.43 -0.08,0.65 0,1.61 1.31,2.92 2.92,2.92 1.61,0 2.92,-1.31 2.92,-2.92s-1.31,-2.92 -2.92,-2.92z"/>

你有沒有將此添加到您的搖籃文件

android { defaultConfig { 
vectorDrawables.useSupportLibrary = true 
} }
