在我的几个应用程序中实现新的Snackbar之后,我收到以下错误：

// make new snackbar
this.snackbar = Snackbar.make(view,"Here's a Snackbar",Snackbar.LENGTH_LONG).show();

概要：
我正在使用Snackbar
我正在使用CoodinartorLayout
>我没有使用DrawerLayout

基于异常行中的android.support.v4.widget.ViewDragHelper.shouldInterceptTouchEvent(SourceFile：1014),我猜测它与Snackbar的“解雇”有关？
也许我不应该在OnPause中解雇Snackbar？我曾经用烤面包机做这个.
解决方法
我发现一个解决方案是通过使用findViewById(android.R.id.content)来确保它不是“可刷卡”的.该解决方案基本上“避免”并防止错误发生.
Snackbar.make(findViewById(android.R.id.content),"Hello!",Snackbar.LENGTH_LONG);
应在23.2.1：https://stackoverflow.com/a/36004008/950427中修正
