android开发webview使用h5播放视频时横竖屏切换的解决方法

1.xml代码

<activity
    android:hardwareAccelerated="true"
    android:name=".WebViewActivity"
    android:configChanges="orientation|keyboardHidden|screenSize"
    android:screenOrientation="portrait" />

2.kotlin代码

webView.webChromeClient = object : WebChromeClient() {
    override fun onShowCustomView(view: View, callback: WebChromeClient.CustomViewCallback) {
        super.onShowCustomView(view, callback)
        showCustomView(view, callback)
    }
    override fun onHideCustomView() {
        super.onHideCustomView()
        hideCustomView()
    }
}

private fun setStatusBarVisibility(visible: Boolean) {
    val flag = if (visible) 0 else WindowManager.LayoutParams.FLAG_FULLSCREEN
    window.setFlags(flag, WindowManager.LayoutParams.FLAG_FULLSCREEN)
}

private var customView: View? = null
private var customViewCallback: WebChromeClient.CustomViewCallback? = null

private fun showCustomView(view: View, callback: IX5WebChromeClient.CustomViewCallback) {
    requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
    if (customView != null || view.parent != null) {
        callback.onCustomViewHidden()
        return
    }
    (window.decorView as FrameLayout).addView(view, FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT))
    customView = view
    setStatusBarVisibility(false)
    customViewCallback = callback
}

private fun hideCustomView() {
    requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
    if (customView == null) {
        return
    }
    setStatusBarVisibility(true)
    (window.decorView as FrameLayout).removeView(customView)
    customView = null
    customViewCallback?.onCustomViewHidden()
    webView.visibility = View.VISIBLE
}
