在onFilterTouchEventForSecurity上获取NullPointerException

Question

我已经构建了应用程序,我集成了YouTube API,它工作正常,没有任何崩溃,但在Fabric我检查了一些崩溃的问候ipf.onFilterTouchEventForSecurity.以下是崩溃的完整日志:

我无法重现它，但您可以尝试以下几种方法：

如果可能的话，尝试添加文档中建议的android:filterTouchesWhenObscured=false透明剂：

指定当视图窗口被另一个可见窗口遮挡时是否过滤触摸。设置为 true 时，每当视图窗口上方出现 Toast、对话框或其他窗口时，视图都不会接收触摸。有关更多详细信息，请参阅查看安全文档。

可以是布尔值，例如“true”或“false”。

否则，您可以尝试覆盖根视图的调度方法并在那里放置一个 try catch，如果需要，您可以将其用作自定义组件。

@Override
void dispatchTouchEvent(MotionEvent event){
    try{
        super.dispatchTouchEvent(event);
    }
    catch (Exception e){
        e.printStackTrace();
    }
}
