What is the difference between the three drawable folders in the res folder in the project hierarchy? If I have an image to put into a folder, which folder do I put it in?

推荐答案

我要采取猜测，三可绘制文件夹是绘制-LDPI ，绘制-MDPI 和绘制 - 华电国际。在这种情况下，如果你坚持与所有这些文件夹，你需要把每一个图像，大小相匹配的指示屏幕像素密度。 // WWW：这是在href="http://developer.android.com/guide/practices/screens_support.html">在线文档的blog帖子。你可以找到一个集显示使用不同的绘制资源样本项目基于屏幕像素密度这里

I am going to take a guess that "the three drawable folders" are drawable-ldpi, drawable-mdpi, and drawable-hdpi. In that case, if you stick with all of those folders, you need to put one image in each, sized to match the indicated screen density. This is discussed in the online documentation as well as this blog post. You can find a set of sample projects showing use of different drawable resources based on screen density here.

如果你是刚刚开始在Android开发，你可以摆脱所有这三个目录，并创建一个绘制目录，把你的图片在那里。但是，最终的高质量的应用程序，你会想在不同的设备/仿真器具有不同的屏幕密度测试你的图片，并可能有不同的图像的每个密度来提高你的应用程序的外观。

If you are just starting out in Android development, you can get rid of all three of those directories and create a single drawable directory, putting your image in there. Eventually, though, for a quality application, you will want to test your images on different devices/emulators with different screen densities, and possibly have different images for each density to improve the look of your app.
