World Wind Java开发之三显示状态栏信息

先来看下本篇博客索要达到的效果：

找到源码下的gov.nasa.worldwind.util下的StatusBar.java文件，可以看到状态栏显示的信息主要包括视点高度以及对应空间点三维坐标以及是否使用网络等信息。在后续的开发中采用离线模式，因此不需要联网，也不显示网络状态信息。代码依次如下面几幅图所示：

![Center 1][]![Center 2][]![Center 3][]![Center 4][]![Center 4][]![Center 5][]

修改完源代码后，将源代码文件导出为jar包，在我们的工程下引用即可。后面如果需要修改源代码，都按这种方式操作；具体操作步骤如下：

![Center 6][]![Center 7][]![Center 8][]![Center 9][]

需要说明的是导出的时候可以只勾选src文件夹也可以默认。导出后将worldWind2.0.jar文件拷贝到我们的工程目录下，添加应用即可。下面是所有源码：
