    paint.setAntiAlias(true);
    paint.setFilterBitmap(true);

    canvas.drawARGB(0,0);
    paint.setColor(Color.parseColor("#BAB399"));
    canvas.drawCircle(sbmp.getWidth() / 2+0.7f,sbmp.getHeight() / 2+0.7f,sbmp.getWidth() / 2+0.1f,paint);
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
    canvas.drawBitmap(sbmp,rect,paint);


            return output;
}

我的xml代码是：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:orientation="horizontal" >

        <com.example.scaletypedemo.RoundedImageView
            android:layout_marginLeft="30dp"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:layout_centerInParent="true"
            android:scaleType="centerCrop"
            android:src="@drawable/a"
            android:adjustViewBounds="true" />

         <ImageView
                android:layout_marginLeft="50dp"
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:scaleType="centerCrop"
                android:src="@drawable/a" />

    </LinearLayout>

</RelativeLayout>

所以,问题是,如果我使用ImageView,显示的图像不会被拉伸但是如果我使用相同的图像并将其显示在RoundedImageView中并保持所有属性相同;图像被拉伸,如下面的屏幕截图所示：

请帮助防止RoundedImageView中显示的图像拉伸………..我在这一点上非常困难.

编辑：应用正红的解决方案后,它解决了拉伸问题,但后来没有显示完整的一轮.

提前致谢！！！
