如何修复Eclipse / Android安装？图形XML编辑器中的PNG加载问题

很长一段时间，我的Eclipse环境与Android插件运行顺利。在软件更新过程中应用的更新行的某个地方它已经崩溃了。开始发生的第一个问题是在为布局文件运行Android插件图形编辑器时丢失了“按钮”Form Widget图形。我在错误日志中收到以下相关错误：

!MESSAGE voice_recog.xml: android.webkit.WebView
!MESSAGE main_new.xml: Failed lot load /Developer/android-sdk-mac_x86-1.5_r3/platforms/android-11/data/res/drawable-hdpi/btn_default_normal.9.png
!STACK 0
javax.imageio.IIOException: Error reading PNG metadata

我将png文件放在我的硬盘上并从Finder启动了图像查看器。它显示没有错误。我不知道为什么IDE无法将其加载到图形编辑器中。如果您查看帖子末尾的详细错误日志转储，您将看到发生的异常是 java.io.EOFException （“由此引起：java.io.EOFException”）。 / p>

我注意到其中一个更新在我的硬盘上安装了Android-12，并且IDE正在寻找Android-11目录中的PNG。但是正如我之前所说，该文件确实存在于错误消息中显示的Android-11路径中。我只是指出这一点，以防它可能表明我的设置中存在其他一些问题。

注意：我尝试将图形布局编辑器切换到不同的设备，从“3.7英寸WVGA”切换到其他几个，我得到的PNG文件加载错误比以前更多（更多），还有ClassCast异常。我也尝试将Android平台从3.0切换到我的目标1.6，这也没有帮助。就好像现在有一些PNG文件加载代码破坏了。我希望不要完全重新安装Eclipse和ADT，特别是因为我最终可以回到同一个故障点，所以如果有人遇到这些问题并解决了它们，请回复。

以下是PNG文件原始失败加载的完整错误日志跟踪：

我通过在图形布局框的右上角从Android 3.0中取出Eclipse来解决这个问题。我将版本下载到Android 2.3.3，一旦完成加载这个版本，我就明白了。 “按钮”png加载得很好。
