列表item大小会自己变

### Environment
- [x] Autosize Version: 1.2.1
- [x] Target Android Version: 28
- [x] Device Model: 华为p10 plus
- [x] Device Resolution: 1920* 1080
- [x] Design Size On AndroidManifest: 1280*720
机型无关，其它手机也会出现

### Bug Description:

看了答疑，在adapter的onBindHodlder方法中调用了
AutoSize.autoConvertDensityOfGlobal(activity)
但是还是出现了item布局时大时小的问题。
图片中的两个item，内容一模一样的，但是展示却不一样。返回到桌面，过十几秒再进入APP，复现概率大。

### Others:

Start by reproducing the inconsistent item sizing on Android 8.0/API 28 with AndroidAutoSize 1.2.1, using the adapter's onBindHodlder call to AutoSize.autoConvertDensityOfGlobal(activity) as the initial entry point. Compare identical items across re-entry to the app; done means the same item layout renders consistently, with the cause confirmed rather than only observed.
