我知道这个问题不是由于代码引起的，但我需要防止崩溃.

I know that this issue is not because of code but I need to prevent crashing.

以下是我面临问题的设备列表:

推荐答案

我无法复制它，但是您可以尝试以下几种操作:

I am not able to reproduce it but there are several things you can try:

如果可能，请尝试将android:filterTouchesWhenObscured=false作为纯文本添加 ="https://developer.android.com/reference/android/R.attr.html#filterTouchesWhenObscured" rel ="nofollow noreferrer">文档:

If possible try adding android:filterTouchesWhenObscured=false as pellucide suggested from the docs:

指定当视图的窗口被遮盖时是否过滤触摸 在另一个可见的窗口旁边.设置为true时，视图将不会接收 每当烤面包，对话框或其他窗口出现在菜单上方时，触摸 视图的窗口.有关更多信息，请参阅View安全性文档. 详细信息.

Specifies whether to filter touches when the view's window is obscured by another visible window. When set to true, the view will not receive touches whenever a toast, dialog or other window appears above the view's window. Refer to the View security documentation for more details.

可能是布尔值，例如"true"或"false".

May be a boolean value, such as "true" or "false".

否则，您可以尝试覆盖根视图的分发方法 并在其中放置try catch，您可以将其用作

Otherwise, you can try overriding the dispatch method of your root view and place a try catch there, you can use it as a custom Component if needed.

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