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,在错误日志上：

救命？

最佳答案 似乎有很多原因导致图形编辑器出现错误并且无法打开,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.单击底部的“添加自定义…”选项.在弹出窗口中选择自定义设置并删除它们.重新打开图形编辑器后,它对我有用.

希望这有助于其他人.
