如何使用库JAR导入后现有项目

Question

创建画廊的应用程序，然后我想通过添加名为外部库添加在我的画廊缩放效果图片：ImageVIewZoom.jar 从这个链接： https://github.com/kilaka/ImageViewZoom 我只将不是所有ImageViewZoom项目的jar文件都添加到我的项目中。

我添加库这种方式如下：

1 - 我的库 - >右键 - >导入 - >文件系统 - > ImageViewZoom.jar

2- myProject的 - >右键 - >属性 - > Java Build Path - > Libraries - > Add Jar - > ImageViewZoom.jar。

现在jar文件已经在我的项目中如何在我的画廊类中使用或使用jar类，这样我最终在运行我的应用程序时，我的图像将具有缩放效果。

是新来的Android和第一次使用我的项目内外部库，

编辑： 请问我需要添加我的画廊类的内部或进口里面的一些代码，如果是的话怎么会是。

这是我的画廊类，实际上它不是我的代码，但我在这里创建了stackoverflow并使用它来形成无限的画廊。

任何帮助将高度赞赏.thanks很多

是的，这是正确的方式来增加的.jar库。你可以像使用普通java一样使用它（假设）。

ABCD a = new ABCD(); 
a.method(); 

就你而言，你的库有一个示例代码。 See here.
