一、官方介绍
HTML5 video support
HTML5 Video support In order to support inline HTML5 video in your application,
you need to have hardware acceleration turned on, and set a WebChromeClient.
For full screen support, implementations of onShowCustomView(View, WebChromeClient.CustomViewCallback)
and onHideCustomView() are required, getVideoLoadingProgressView() is optional.
- 打开硬件加速(3.0以上版本支持)
- set一个WebChromClient,实现onShowCustomView() 方法和onHideCustomView()方法
- 全屏支持
二、实现解决
- 打开硬件加速
- 在Manifest中,对应的Activity添加: android:hardwareAccelerated = “true”。
- 防止h5重新加载:Manifest中,对应的Activity添加: android:configChanges=“keyboardHidden|orientation|screenSize”
- 切换横屏时,屏幕的H5内容始终以竖屏显示:Manifest中,对应的Activity添加: android:screenOrientation=“portrait”
<activity
android:name=".uicomponent.WebViewActivity"
android:configChanges="orientation|screenSize|keyboardHidden" //防止h5重新加载
android:hardwareAccelerated="true" //硬件加速
android:screenOrientation="portrait" //当我们切换横竖屏的时候,屏幕的内容始终以竖屏显示,而不会根据屏幕的方向来显示内容
android:theme="@style/AppTheme.NoActionBar" />
-
WebView中设置WebChromClient实现接口onShowCustomView() 方法和onHideCustomView()方法, 实现后即显示全屏播放按钮,但是点击无反应,需要实现全屏支持。
-
全屏支持实现:WebView在点击全屏按钮后调用onShowCustomView方法,而全屏的视频会在其参数view中进行渲染。我们需要在Activity中写一个viewRoot,在onShowCustomView触发后,将其view传入viewRoot,且使APP横屏,达到全屏显示。
@SuppressLint("StaticFieldLeak")
private var mCustomView: View? = null //全屏渲染视频的View
private var webRoot: FrameLayout? = null// 显示全屏视频的布局
private var mCustomViewCallback: CustomViewCallback? = null
@SuppressLint("SourceLockedOrientationActivity")
override fun onShowCustomView(view: View?, callback: CustomViewCallback?) {
super.onShowCustomView(view, callback)
try {
if (mCustomView != null) { //当上一个view存在时,隐藏全屏
callback?.onCustomViewHidden()
return
}
mCustomView = view
webRoot?.addView(mCustomView)
mCustomViewCallback = callback
webView?.visibility = View.GONE
val actionBar = supportActionBar
actionBar?.hide()
requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
} catch (e: Exception) {
e.printStackTrace()
}
}
@SuppressLint("SourceLockedOrientationActivity")
override fun onHideCustomView() {
try {
webView?.visibility = View.VISIBLE
val actionBar = supportActionBar
actionBar?.show()
if (mCustomView == null) { //当上一个view不存在时,不处理
return
}
mCustomView?.visibility = View.GONE
webRoot?.removeView(mCustomView)
mCustomViewCallback?.onCustomViewHidden()
mCustomView = null
requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
} catch (e: Exception) {
e.printStackTrace()
}
super.onHideCustomView()
}
override fun onProgressChanged(view: WebView?, newProgress: Int) {
super.onProgressChanged(view, newProgress)
progressBar?.progress = newProgress
}
xml
<FrameLayout
android:id="@+id/web_root"
app:layout_constraintBottom_toTopOf="@id/v_bottom"
app:layout_constraintTop_toBottomOf="@id/v_top"
android:layout_width="match_parent"
android:layout_height="0dp">
<WebView
android:id="@+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ProgressBar
android:id="@+id/progress_bar"
style="?android:progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="1.5dp"
android:max="100"
android:progressDrawable="@drawable/webview_progress_bar_style" />
</FrameLayout>
