安卓端咨询一个webview的问题

需求希望打开的H5页面撑满又不能遮挡状态栏，我在onShow的时候获 currentWebview.setStyle({
// position:'static',
top: safeAreaTop,
height: sysInfo.safeArea.height, // 动态调整高度
})，跳转到其他页面通过原生导航栏返回到这个页面后top就消失了。但打印出来top是存在的
"contentAdjust":false,"name":"2","animationAlphaBGColor":"#FFFFFF","background":"#FFFFFF","debugRefresh":{"isTab":false,"arguments":"{\"path\":\"pages/ai/index\",\"query\":\"\"}"},"bounce":"vertical","rpxCalcMaxDeviceWidth":750,"backgroundColorTop":"#FFFFFF","backgroundColorBottom":"#FFFFFF","webviewBGTransparent":true,"uniPageUrl":{"path":"pages/ai/index","query":""},"locale":"zh-Hans-CN","top":40,"height":781}
有人遇到过类似的情况吗
