清除CircularImageView中的图像不起作用在CircularImageView中设置图像时出现StackoverFlowException

Question

我正在使用https://github.com/Pkmmte/CircularImageView来获取图片循环。我想在imageView中清除图像，如果已经设置的话。没有解决方案工作建议@ How to clear an ImageView in Android?。如果您使用过CirularImageView，我该如何清除图像？

编辑 编辑
我想我可以尝试在重置图像后显示空白的灰色视图但由于这不起作用，我正在编辑问题以告诉您实际问题。

这是：
我正在使用RecyclerView向朋友们展示。我的一个朋友列表没有他的图片所以我试图显示默认的头像是SVG图像。第一次当我向下滚动到他的视图时，它显示完美。当我第二次再次回滚给他时，它会抛出StackOverFlow异常。

mDefaultUserPhoto = MrVector.inflate(

            getResources(), R

                    .drawable.vector_default_user_photo);
}

circularIV.setImageDrawable(mDefaultUserPhoto); // This is what hits for every friend when scrolled and where the StackoverFlowException occured..

Answer 1

试试这个：

boolean checkDrawable = (ImageView.getDrawable() != null);
if(checkDrawable ) {
 // imageView has image
}
else {
// no image assigned in image view
}

Answer 2

尝试使用以下内容，

imageview.setImageResource(0);

或

imageView.setBackground(null);

Answer 3

建议的方法不起作用，因为您可以在CircleImageView的来源中看到开发人员对Bitmap中设置的onDraw进行了验证：

    @Override
public void onDraw(Canvas canvas) {
    // Don't draw anything without an image
    if(image == null)
        return;
    ...
    ...
}

因此，这意味着如果将null设置为位图，则不会执行此方法，并且仍将绘制旧位图。我的建议只是隐藏视图，使用circleImageView.setVisibility(View.GONE);或circleImageView.setVisibility(View.INVISIBLE);如果您希望视图占用布局建议的空间。

Answer 4

try this..


class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);

    }

    public ChimmerRoundedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);

    }

    public ChimmerRoundedImageView(Context context, AttributeSet attrs,
            int defStyle) {

        super(context, attrs, defStyle);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        float radius = 90.0f; // angle of round corners
        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);

    }
}

Answer 5

如果您的位图为空，则在onBindViewHolder()的{​​{1}}中创建一个包含空图片或默认图片的位图，然后将其设置为RecyclerView.Adapter

Answer 6

我找不到如何在CircularImageView中清除图像的方法，但可以找到StackOverflowException的原因。我使用Picasso作为缓存库，“不清除”缓存。所以转移到UniversalImageLoader，它工作正常，没有OutOfMemoryException或StackOverflowException。

如果你想坚持使用Picasso，那么你可能想要添加代码来清除缓存。这个linke有帮助 - ＆gt; Clear Cache memory of Picasso
