在 CircularImageView 中清除图像不起作用 |在 CircularImageView 中设置图像时出现 StackoverFlowException

Question

我正在使用https://github.com/Pkmmte/CircularImageView 获取图片通知。如果已经设置，我想清除 imageView 中的图像。没有任何解决方案建议@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
我想我可以在重置图像后尝试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你实际问题。

这里是：
我正在使用 RecyclerView 向朋友展示。我的一个朋友列表没有他的照片，所以我尝试显示默认头像，即 SVG 图像。当我第一次向下滚动到他的视图时，它完美地显示出来。当我第二次再次滚动回他时，它会引发 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

尝试以下方法，

imageview.setImageResource(0);

或

imageView.setBackground(null);

Answer 3

建议的方法不起作用，因为正如您在CircleImageView 的来源中看到的那样，开发人员对onDraw 中设置的Bitmap 进行了验证：

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

所以，这意味着如果你将null设置为位图，这个方法将不会被执行，仍然会绘制旧的位图。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

在RecyclerView.Adapter 的onBindViewHolder() 中，如果您的位图为空，则使用空图像或默认图像创建一个位图，然后将其设置为CircularImageVeiw

   if(bitmap==null){
        //Creating empty bitmap
        bitmap= Bitmap.createBitmap(100,100, Bitmap.Config.ARGB_8888);
    }
   viewHolder.imageView.setImageBitmap(bitmap);

Answer 6

我找不到如何清除 CircularImageView 中的图像的方法，但可以找到 StackOverflowException 的原因。我使用毕加索作为“不清除”缓存的缓存库。所以转移到 UniversalImageLoader 工作正常，没有 OutOfMemoryException 或 StackOverflowException。

如果您想坚持使用毕加索，那么您可能需要添加代码以清除缓存。这个链接有帮助-> Clear Cache memory of Picasso
