问题描述
当我将视图的背景设置为特定的NinePatch图像时，在Eclipse的 Graphical Layout 标签中遇到了这个奇怪的错误.
I get this strange error in Graphical Layout tab on eclipse when I set the background of my view to this specific NinePatch image.
仅当我要预览xhdpi或xxhdpi布局时才出现错误.在ldpi，mdpi和hdpi上，预览效果都很好.
I get the error only when I want to preview an xhdpi or xxhdpi layout. On ldpi, mdpi and hdpi it previews fine.
有什么想法吗?

推荐答案
图像太高.它会一遍又一遍地重复相同的像素，这完全是 九个补丁的作用.
The image is way too high. It repeats the same pixel over and over again, that is exactly what nine patches do.
如果它是一个渐变(从名称来看，很难说出图像)，请使用XML来创建它.它将看起来更好，并且几乎不需要存储.
If it's a gradient (judging from the name, hard to say with the image) use XML to create it. It will look a lot nicer and costs almost no storage.
至于原始错误，我的猜测是重复像素太多.但这只是一个猜测.
As for the original error, my guess is that it's just too many repeated pixels. But that's just a guess.
