集成X5WEBVIEW可以选择全屏模式为标准全屏还是x5全屏，而不设置默认为false。
首先看看标准全屏的基本设置，
if (webView.getX5WebViewExtension() != null) { ???????????Bundle data = new Bundle(); ???????????data.putBoolean("standardFullScreen", false);// true表示标准全屏，false表示X5全屏；不设置默认false， ???????????data.putBoolean("supportLiteWnd", false);// false：关闭小窗；true：开启小窗；不设置默认true， ???????????data.putInt("DefaultVideoScreen", 1);// 1：以页面内开始播放，2：以全屏开始播放；不设置默认：1 ???????????webView.getX5WebViewExtension().invokeMiscMethod("setVideoParams", data); ???????}如果使用的是标准全屏那么，显示页面如下：
可以看到典型的 可以横竖屏切换的按钮，锁屏的按钮，缓存和分享的按钮以及视频名标题。 这些内容在一些场景下是可能不希望看到显示的，比如缓存按钮，比如使用模板打开的页面分享出来是模板地址。
因此需要一种标准的全屏模式，而非x5全屏模式。
使用标准全屏模式代码如下：
if (webView.getX5WebViewExtension() != null) { ???????????Bundle data = new Bundle(); ???????????data.putBoolean("standardFullScreen", true);// true表示标准全屏，false表示X5全屏；不设置默认false， ???????????data.putBoolean("supportLiteWnd", false);// false：关闭小窗；true：开启小窗；不设置默认true， ???????????data.putInt("DefaultVideoScreen", 1);// 1：以页面内开始播放，2：以全屏开始播放；不设置默认：1 ???????????webView.getX5WebViewExtension().invokeMiscMethod("setVideoParams", data); ???????}需要在内部处理全屏的交互，在布局中增加代码如下：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
???android:layout_width="match_parent"
???android:layout_height="match_parent"
android:id="@+id/webViewLayout"
???android:orientation="vertical">
<!-- 视频全屏--> ???<FrameLayout ???????android:id="@+id/video_fullView" ???????android:layout_width="fill_parent" ???????android:layout_height="fill_parent" ???????android:background="@color/black" ???????android:visibility="gone"> ???????<TextView ???????????android:id="@+id/tv_touch" ???????????android:layout_width="150dp" ???????????android:layout_height="45dp" ???????????android:layout_gravity="right" ???????????android:layout_marginTop="20dp" ???????????android:background="@color/transparent" /> ???</FrameLayout>
</FrameLayout>
首先添加 一个webviewChromeClient，处理onShowCustomView、onHideCustomView两个方法的回调。在类中添加如下代码
private IX5WebChromeClient.CustomViewCallback xCustomViewCallback; ???private FrameLayout video_fullView;// 全屏时视频加载view ???private View xCustomView; ???private com.tencent.smtt.sdk.WebChromeClient xwebchromeclient = new com.tencent.smtt.sdk.WebChromeClient() { ???????@Override ???????public void onProgressChanged(com.tencent.smtt.sdk.WebView webView, int percent) { ???????????super.onProgressChanged(webView, percent); ???????????if (percent > 40) { ???????????????webView.setVisibility(View.VISIBLE); ???????????} ???????} ???????// 拦截全屏调用的方法 ???????@Override ???????public void onShowCustomView(View view, IX5WebChromeClient.CustomViewCallback callback) { ???????????super.onShowCustomView(view, callback); ???????????getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); ???????????Log.e("my","onShowCustomView----xCustomView:" + xCustomView); ???????????webView.setVisibility(View.INVISIBLE); ???????????// 如果一个视图已经存在，那么立刻终止并新建一个 ???????????if (xCustomView != null) { ???????????????callback.onCustomViewHidden(); ???????????????return; ???????????} ???????????view.setVisibility(View.VISIBLE); ???????????video_fullView.addView(view); ???????????xCustomView = view; ???????????xCustomView.setVisibility(View.VISIBLE); ???????????xCustomViewCallback = callback; ???????????video_fullView.setVisibility(View.VISIBLE); ???????} ???????@Override ???????public void onHideCustomView() { ???????????super.onHideCustomView(); ???????????Log.e("my","onHideCustomView----xCustomView:" + xCustomView); ???????????if (xCustomView == null){ ???????????????// 不是全屏播放状态 ???????????????return; ???????????} ???????????getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); ???????????xCustomView.setVisibility(View.GONE); ???????????video_fullView.removeView(xCustomView); ???????????xCustomView = null; ???????????video_fullView.setVisibility(View.GONE); ???????????xCustomViewCallback.onCustomViewHidden(); ???????????webView.setVisibility(View.VISIBLE); ???????} ???}; ???/** ????* 判断是否是全屏 ????* ????* @return ????*/ ???public boolean inCustomView() { ???????return (xCustomView != null); ???} ???/** ????* 全屏时按返加键执行退出全屏方法 ????*/ ???public void hideCustomView() { ???????xwebchromeclient.onHideCustomView(); ???????getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); ???}设置x5webview的webchrome，代码如下：
webView.setWebChromeClient(xwebchromeclient);
为了处理返回事件，还需要加上如下代码：
@Override ???public boolean onKeyDown(int keyCode, KeyEvent event) { ???if (inCustomView() && keyCode == KeyEvent.KEYCODE_BACK) { ???????????????hideCustomView(); ???????????????return ; ???????} ???return super.onKeyDown(keyCode, event); ???}这样就大功告成。
