} // make new snackbar this.snackbar = Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG).show(); // chris banes example // Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG).setAction("Action", null).show(); } }); } @Override public void onPause() { super.onPause(); // dismiss when user clicks "home" if (this.snackbar != null) { this.snackbar.dismiss(); } }}Summary:I am using the SnackbarI am using the CoodinartorLayoutI am not using the DrawerLayoutGoogle Issues:http://code.google.com/p/android/issues/detail?id=175501http://code.google.com/p/android/issues/detail?id=103888Based on the android.support.v4.widget.ViewDragHelper.shouldInterceptTouchEvent(SourceFile:1014) at line in the Exception, I am guessing it has to do with the "dismissing" of the Snackbar?Maybe I should not dismiss the Snackbar in onPause? I used to do this with Toasts. 解决方案 One solution I found was to make sure it was not "swipe-able" by using findViewById(android.R.id.content). This solution basically "avoids" and prevents the error from happening.Snackbar.make(findViewById(android.R.id.content), "Hello!", Snackbar.LENGTH_LONG);Should be fixed in 23.2.1: https://stackoverflow.com/a/36004008/950427 这篇关于取消Snackbar/ViewDragHelper时发生ArrayIndexOutOfBoundsException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 1403页，肝出来的..
