我有一个 ImageView,我想用它来制作它rounded corners
.
我用这个:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="@null"/>
<stroke android:width="1dp"
android:color="#ff000000"/>
<corners android:radius="62px"/>
</shape>
并将此代码设置为我的图像视图的背景。
它可以工作,但是我放在的 src 图像ImageView
正在走出边界,无法适应新的形状。
我该如何解决这个问题?
试试这个:
public class CustomImageView extends ImageView {
public static float radius = 18.0f;
public CustomImageView(Context context) {
super(context);
}
public CustomImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onDraw(Canvas canvas) {
//float radius = 36.0f;
Path clipPath = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
clipPath.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(clipPath);
super.onDraw(canvas);
}
}
and
<your.pack.name.CustomImageView
android:id="@+id/selectIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:scaleType="centerCrop" />
CustomImageView iconImage = (CustomImageView )findViewById(R.id.selectIcon);
iconImage.setImageBitmap(bitmap);
or,
ImageView iv= new CustomImageView(this);
iv.setImageResource(R.drawable.pic);
