请问怎么集成到compose中使用
可以这样简单使用
AndroidView(
modifier = Modifier
.padding(padding)
.fillMaxSize(),
factory = {
LinearLayout(it).apply {
layoutParams = ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT
)
}
},
update = {
AgentWeb.with(activity.context as Activity)
.setAgentWebParent(
it,
LinearLayout.LayoutParams(-1, -1)
)
.useDefaultIndicator()
.setWebViewClient(LoginClient())
.createAgentWeb()
.ready()
.go(SSPaiUrl.LOGIN_URL).apply {
agentWebSettings.webSettings.javaScriptEnabled = true
agentWebSettings.webSettings.builtInZoomControls = true
agentWebSettings.webSettings.displayZoomControls = false
agentWebSettings.webSettings.useWideViewPort = true
}
}
)
那个所谓的activity，是LocalView.current，没有试过LocalContext.current。但是要是想深入使用的话，也许还要写很多状态管理之类的。
这是我使用的
