无法将Palette中的元素添加到编辑器中，编辑器上没有任何内容，调色板似乎没问题。从新创建的项目打开main.xml布局文件时出现此消息：
The project target (Android 2.2) is still loading.
一旦完成该过程，布局将自动刷新。
另外，在错误日志中：

帮助？
答案 0 :(得分：2)
图形编辑器出错并且无法打开的原因似乎有很多，但我通过删除自定义设备配置修复了我的编辑器。
要在图形编辑器中执行此操作，请打开与编辑器中显示的设备相关的下拉列表。例如3.7in WVGA Nexus。 点击底部的“添加自定义...”选项。 在弹出中选择您的自定义设置并删除。重新打开图形编辑器后，它对我有用。
希望这有助于其他人。
