我有一个ImageView,我想用它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imageview的背景.它可以工作,但我放在它上面的src图像ImageView是走出边界而不适应新的形状.

我该如何解决这个问题？

我最近从ImageView扩展到创建一个CircularImageView类,它使图像呈圆形,带有彩色边框.这是通过onDraw(canvas)方法绘制到传入的画布上完成的:

//load the bitmap
    loadBitmap();

    // init shader
    if(image !=null)
    {   
        shader = new BitmapShader(Bitmap.createScaledBitmap(image, viewWidth + (borderWidth * 2), viewHeight + (borderWidth * 2), true), Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
        paint.setShader(shader);

        int circleCenter = viewWidth / 2;

        // circleCenter is the x or y of the view's center
        // radius is the radius in pixels of the cirle to be drawn
        // paint contains the shader that will texture the shape
        canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter + borderWidth, paintBorder);
        canvas.drawCircle(circleCenter …
