我在线性布局中有一个文本视图和图像视图。 Textview 位于顶部,imageview 位于底部。我使用下面的线条来实现线性布局的圆角。但 imageview 的角不是圆角的。我看到只有线性布局的顶角是圆角的。如何使 imageview 的底角圆角?(如果我删除图像视图,我会看到所有的角都是圆角的)
圆角.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#ffffff" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
</shape>
main.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="50dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="50dp"
android:background="@xml/rounded_corners"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="xxxxxxxx" />
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
android:src="@drawable/my_image_view" />
</LinearLayout>
screen shot :
你可以将图像的左下角和右下角变成圆角,如下所示:
code:
public static Bitmap getRoundCornerBitmap(Bitmap bitmap, int radius) {
int w = bitmap.getWidth();
int h = bitmap.getHeight();
Bitmap output = Bitmap.createBitmap(w, h, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
final RectF rectF = new RectF(0, 0, w, h);
canvas.drawRoundRect(rectF, radius, radius, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, null, rectF, paint);
/**
* here to define your corners, this is for left bottom and right bottom corners
*/
final Rect clipRect = new Rect(0, 0, w, h - radius);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC));
canvas.drawRect(clipRect, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, null, rectF, paint);
bitmap.recycle();
return output;
}
此方法可以为您提供左下角和右下角圆角的图像。
