问题描述
我是Android的新手，我已经完成了一个以像素艺术为特色的游戏。我打算从小像素化的png文件中放大我的图像（图像视图和绘制到画布的位图）。问题是，我似乎无法禁用抗锯齿，无论我尝试什么方法。图像总是模糊不清。
我的所有图片都在一个'drawable'文件夹中。
我在xml的ImageView中尝试了android：antialias =false。
I'm new to Android, and I've finished a game which was meant to feature pixel art. I was going to scale up my images (imageviews and bitmaps drawn to canvas) from small pixelated png files. The thing is, I could not seem to disable anti-aliasing whatever method I tried. The image was always blurred.All my images are in one 'drawable' folder.I tried android:antialias="false" within the ImageView in the xml.
尝试了这里描述的方法：

在将位图绘制到画布上时尝试更改绘画（paint.setAntiAlias（false））。
Tried the method described here: http://www.41post.com/4241/programming/android-disabling-anti-aliasing-for-pixel-art\Tried changing the paint (paint.setAntiAlias(false)) when drawing the bitmap onto a canvas.
甚至尝试将ImageView链接到xml位图drawable with antialias =false
And even tried linking the ImageView to a xml bitmap drawable with antialias="false"
我错过了什么吗？最后，我不得不忍着留下一些模糊图像并将大图像作为大图像并且不在xml文件中调整大小。
Am I missing something? In the end I had to just settle with leaving some images blurry and having the big images as big images and not resizing in the xml file.
推荐答案
从中，看起来像 Paint＃setFilterBitmap（）始终处于启用状态，并且在启用硬件加速时无法禁用。尝试检查您的应用是否正在使用硬件加速。
From the Hardware Acceleration Guide, it looks like Paint#setFilterBitmap() is always enabled and cannot be disabled when hardware acceleration is enabled. Try checking to see if your app is using hardware acceleration.
我在启用使用主机GPU选项时在模拟器中看到了类似的行为，并发现可以通过使用 Paint＃setFilterBitmap（true）强制没有抗锯齿行为的设备具有该行为。虽然没有禁用主机GPU选项，但我无法禁用模拟器中的行为。
I've seen similar behavior in the emulator when enabling the "Use host GPU" option, and found that a device that didn't have the anti-aliasing behavior could be forced to have that behavior by using Paint#setFilterBitmap(true). I was not able to disable the behavior in the emulator though without disabling the host GPU option.
