问题描述
研究已经无果而终，因为所有其他引用这个错误似乎是可靠的重复;我无法始终如一地重复这个错误：
Research has been fruitless because all other references to this error seem to be reliably repeatable; I'm unable to consistently repeat this error:

正如我上文所述，这个错误不会发生所有的时间的。它似乎发生有关（但不完全）的2-3倍，那么2-3奔跑穿过没有问题。
As I stated above, this error does not occur all the time. It seems to happen about (but not exactly) 2-3 times, then 2-3 runs go through without a problem.
下面是我的资源文件：

这里是我的Java。请注意，我甚至尝试硬编码的宽度和高度为我ViewTarget，但仍然得到不一致的错误。我也试过在我的资源文件中创建占位TextViews，但仍然没有去。
And here is my java. Please notice that I even tried hard-coding a width and height for my ViewTarget, but still get inconsistent errors. I also tried creating placeholder TextViews in my resources file, but still no go.

我是pretty的肯定这是一些时间问题了Android的方式引出对象，但我没有知识就知道为什么他们正确地在某些运行，但不能在其他人绘制的。
I'm pretty sure this is some timing issue with the way android draws out objects, but I don't have the knowledge to know why they're drawn correctly on some runs but not on others.
请不要，除非你确定它已经被其他地方的要求相对于扎普这个问题的的间歇的问题： - ）
Please don't zap this question unless you're sure that it has been asked elsewhere with respect to an intermittent problem :-)
任何帮助是AP preciated。
Any help is appreciated.
推荐答案
这是一个已知的问题：的 Github的问题时，<一个href="https://github.com/amlcurran/ShowcaseView/blob/392e7c345a4bfd2b67058a66759f7889c2d9d601/library/src/main/java/com/github/amlcurran/showcaseview/ShowcaseView.java#L183"相对=nofollow> updateBitmap（）称为为时尚早。
这个问题源于<一个href="https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/graphics/java/android/graphics/Bitmap.java"相对=nofollow> Bitmap.createBitmap（）方法的宽度或高度等于0
一种解决方法是推迟ShowcaseView创造更多：
This is a known issue : Github issues when updateBitmap() is called too early.
This issue comes from Bitmap.createBitmap() method either width or height equals to 0.
A workaround is to delay the ShowcaseView creation more:
someView.post(new Runnable() {
@Override
public void run() {
// display ShowcaseView here
}
});
您也可以从库改变updateBitmap（）方法不创建位图，如果视图宽度或高度是错误的。
You could also change the updateBitmap() method from the library to not create the bitmap if the view width or height is wrong.
