适用于各种屏幕尺寸背景的缩放dpi位图

[英]Scaled dpi bitmaps for various screen sizes' backgrounds

原文 2016-03-17 17:23:39 3 1 android/ xml/ bitmap/ dpi

With Android's nine-patch generator ( http://romannurik.github.io/AndroidAssetStudio/nine-patches.html ), what resolution do you recommend for the base, xhdpi, to retrieve the other scaled dpi bitmaps if I wanted to fit a screen's background on devices ranging from Android wear to Nexus 5 to Android TV? 使用Android的9补丁生成器（ http://romannurik.github.io/AndroidAssetStudio/nine-patches.html ），如果我想适应一个分辨率为xhdpi的基本分辨率，建议为基础xhdpi检索其他比例的dpi位图从Android Wear到Nexus 5到Android TV的设备的屏幕背景？

Are there any alternative ways for this without hardcoding certain dimension-sized png files for particular device screens? 是否有其他方法可以不为特定设备屏幕硬编码某些尺寸大小的png文件？ Thanks! 谢谢！

The best alternative is to use xml drawable, it fits great on all displays. 最好的选择是使用xml drawable，它非常适合所有显示。 read more here: http://developer.android.com/guide/topics/resources/drawable-resource.html 在此处阅读更多信息： http : //developer.android.com/guide/topics/resources/drawable-resource.html

Also, if you plan to make you app for android 5 or later then drawable vector is another great choice: http://developer.android.com/reference/android/graphics/drawable/VectorDrawable.html 另外，如果您打算为Android 5或更高版本制作应用，则可绘制矢量是另一个不错的选择： http : //developer.android.com/reference/android/graphics/drawable/VectorDrawable.html

If non of these did the job for you I recommend you to make your resources for hdpi and xxhdpi, these tow should be scaled with no problems most of time. 如果这些都不适合您，我建议您将资源用于hdpi和xxhdpi，则这些丝束在大多数情况下都应毫无问题地进行扩展。
