我在滚动ExoPlayer videoView列表的时候得到了ANR，这个ANR仅在MotoG4设备上生成（我测试了15个以上不同操作系统的设备，我在Moto G4 OS 7.0上发现了这个ANR）。
ANR in com.it.myapp.debug (com.it.myapp.debug/com.it.myapp.activity.ExploreActivity)
PID: 24035
Reason: Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 58. Wait queue head age: 5509.1ms.)
Load: 5.6 / 4.82 / 4.17
CPU usage from 223502ms to 0ms ago
问题出在哪里？为什么会这样？
