    Here is my method that draws a rectangle with rounded upper and lower right corners, you need to remove the rounding of the upper one and it will work as it should.

    /** Path в поле, чтобы не было инициализации в onDraw(). */ private final Path eventPath = new Path(); /** Радиус закругления. */ private int eventRadius = 3; private void drawRoundRect(float left, float top, float right, float bottom, Paint paint, Canvas canvas) { eventPath.moveTo(left, top); eventPath.lineTo(right, top); eventPath.lineTo(right, bottom); eventPath.lineTo(left + eventRadius, bottom); eventPath.quadTo(left, bottom, left, bottom - eventRadius); eventPath.lineTo(left, top + eventRadius); eventPath.quadTo(left, top, left + eventRadius, top); canvas.drawPath(eventPath, paint); eventPath.reset(); }
    • Something seems to me that your code will not work. Let me take off my view and you will look. I just have everything through rect - Ivan
    • and what's the difference if drawn on Canvas ? Throw off. - georgehardcore
    • Do you own the last rectangle rounds? - Ivan
    • where does the rectangle? - georgehardcore
    • I am doing an epg. So in the figure these are rectangles drawrect - Ivan

    Cardview should be used in the CardView :

     <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" app:cardCornerRadius="10dp" > <!-- blah-blah--> </android.support.v7.widget.CardView>

    The radius of the corner is set by the app:cardCornerRadius attribute app:cardCornerRadius

    • It's not that anyway. If I place my view in CardView, my obtuse angles go beyond the rounded CardView — Ivan

    • If you draw programmatically (and judging by the chat it is), then naturally it will not work like that. I advise you not to engage in antipattern, but to draw the layout as it should be in XML - then everything will be ok. CardView itself will act as a rectangle - Barmaley
