imageView中的圆角

Question

这是我的xml布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="75dp"
    android:padding="3dp" >
    <ImageView
        android:id="@+id/img"
        android:layout_width="75dp"
        android:layout_height="75dp"
        android:scaleType="fitCenter" 

        />

    <TextView
        android:id="@+id/name"
        android:layout_width="208dp"
        android:layout_height="75dp"
        android:paddingLeft="15dp"
        android:paddingTop="15dp" />


    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="30dp"
        android:layout_gravity="center"
        android:src="@drawable/ash_arrow" />

</LinearLayout>

我怎样才能展现ImageView圆角？

Answer 1

使用以下代码.它可能会帮助你 -

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
    bitmap.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);

final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);
final float roundPx = 12;

paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);

return output;
}

将您的Bitmap图像传递给此方法,并将其作为圆角.
