从图像视图 Android 中删除图像

问题描述

我正在尝试制作一个包含图像库的 ImageView.通过触摸用户请求加载下一张图片.如果在服务器中找不到下一张图片或加载需要时间，我需要旧图片为空.

I'm trying to make an ImageView that holds a gallery of images. By touching the user request to load the next image. If the next image isn't found in the server or takes time to load I need the old image to be empty.

setVisibility(View.GONE) 或 setVisibility(View.INVISIBLE) 对我不起作用，因为当隐形/消失时我停止了 onTouch() 检测(并且用户被锁定到当前图像).

setVisibility(View.GONE) or setVisibility(View.INVISIBLE) don't work for me because when invisible/gone I stop the onTouch() detecting (and the user is locked to current image).

如何让 ImageView 加载空位图或清除(删除)当前位图?

How can I make the ImageView to load a empty bitmap or clear (remove) current bitmap?

推荐答案

我一直在用

imageView.setImageDrawable(null);
