错误:添加到 LayerDrawable 的可绘制对象无效!Drawable 已经属于另一个所有者,但不公开一个常量状态。
今天突然注意到这个错误,不知道是不是因为我刚刚将我的测试设备更新到了Android 8.0。错误消息清楚地表明在浮动操作按钮上设置波纹效果有问题,按下按钮时确实没有波纹效果。但是,我不确定是什么导致了这个问题。实际上,完全相同的错误连续抛出两次。任何帮助将非常感激!该应用程序的其余部分仍然正常运行,但该错误确实困扰着我。
ps minSdkVersion 是22,targetSdkVersion 和compiledSdkVersion 是27
在 MyActivity 中,第 117 行是数据绑定和设置内容视图。
ActivityMyBinding binding = DataBindingUtil.setContentView(
this, R.layout.activity_my);
这是完整的堆栈跟踪:
W/LayerDrawable: Invalid drawable added to LayerDrawable! Drawable already belongs to another owner but does not expose a constant state.
