ArcLayout는

Question

은 내가이 주제에 발견

<com.github.florent37.arclayout.ArcLayout 
       android:layout_width="match_parent" 
       android:layout_height="200dp" 
       app:arc_height="20dp" 
       app:arc_cropDirection="cropOutside" 
       app:arc_position="bottom"> 

       <LinearLayout 
        android:orientation="vertical" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:gravity="center" 
        android:background="#fff"> 
       </LinearLayout> 
      </com.github.florent37.arclayout.ArcLayout> 

하지만 내 레이아웃 pixelize 레이아웃을 호 위해 https://github.com/florent37/ArcLayout를 사용 pixelize : https://github.com/florent37/ArcLayout/issues/8

을하지만 난 코드 아래 사용 방법을 이해 해달라고 :

@override 
protected void dispatchDraw(Canvas canvas) { 
paint.setAntiAlias(true); 
paint.setColor(Color.WHITE); 
int saveCount = canvas.saveLayer(0, 0, getWidth(), getHeight(), null, Canvas.ALL_SAVE_FLAG); 
super.dispatchDraw(canvas); 
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.MULTIPLY)); 
canvas.drawPath(clipPath, paint); 
canvas.restoreToCount(saveCount); 
paint.setXfermode(null); 
}

프로젝트에서이 파일로 이동하십시오 : https://github.com/florent37/ArcLayout/blob/master/arclayout/src/main/java/com/github/florent37/arclayout/ArcLayout.java

dispatchDraw 코드를 문제의 코드로 업데이트하십시오.
