安卓：按钮图像绘制可扩展用于其他屏幕尺寸？ [英] Android: Button image drawable scalable for other screen sizes?

问题描述

我有一个按钮，我加载了绘制。图像比按钮的方式更大，所以我38像素（实际调整大小不是code或XML）调整图像以38。现在，当我加载图像，然后它看起来不错。我担心的是不同的屏幕尺寸，如果屏幕比较小，我的按钮变小，可绘制会越过其边界值吗？我怎样才能解决这个问题非常感谢

I have a button that I am loading a drawable for. The image was way bigger than the button so I resized the image to 38 by 38 pixels (actual resize not code or xml). Now, when I load the image then it looks good. I am worried about different screen sizes, if the screen is smaller and my button becomes smaller, the drawable will cross its boundries right? How can I fix it thanks a lot

PS：我读了Android最佳实践页面，但我不知道是否有比大小不同的3种不同的文件夹复制相同的图像以外的方法

PS: I read the android best practices page but I was wondering if there is a method other than replicating the same image in 3 different folders with different sizes

推荐答案

我猜你已经从阅读的最佳实践知道这一点，但也许你可以使用9片图像。它不适合所有的情况，但如果你有，你只是想延长的边缘图像，这是要走的路。

I guess you already know this from reading the best practices, but perhaps you could use a 9-patch image. It does not suit all situations, but if you have an image that you simply want to extend the edges of, it is the way to go.

如果您不能使用9补丁的具体类型的图像，试试你在模拟器几个不同屏幕尺寸的图像你担心它之前:)。我的经验是可绘制将默认扩展相当不错的。

If you can't use 9-patch for the specific type of image, try your image on a couple of different screen sizes in the emulator before you get worried about it :). My experience is that drawables will scale quite well by default.
