直接上代码

public class CustomFullScreenWebViewClient extends WebChromeClient {WebView webView;Context context;/*** 视频全屏参数*/protected static final FrameLayout.LayoutParams COVER_SCREEN_PARAMS = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);private View customView;private FrameLayout fullscreenContainer;private WebChromeClient.CustomViewCallback customViewCallback;int mOriginalSystemUiVisibility;public CustomFullScreenWebViewClient(Context context, WebView webViewParam) {this.webView = webViewParam;this.context = context;}/*** 视频播放相关的方法*/@Overridepublic View getVideoLoadingProgressView() {FrameLayout frameLayout = new FrameLayout(context);frameLayout.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT));// 添加慢慢弹出来的动画效果AnimationSet animSet = new AnimationSet(true);AlphaAnimation fadeIn = new AlphaAnimation(0.0f, 1.0f);fadeIn.setDuration(800);animSet.addAnimation(fadeIn);return frameLayout;}@Overridepublic void onShowCustomView(View view, CustomViewCallback callback) {super.onShowCustomView(view, callback);showCustomView(view, callback);}@Overridepublic void onHideCustomView() {hideCustomView();}/*** 视频播放全屏**/private void showCustomView(View view, WebChromeClient.CustomViewCallback callback) {// if a view already exists then immediately terminate the new oneif (customView != null) {callback.onCustomViewHidden();return;}((Activity) context).getWindow().getDecorView();FrameLayout decor = (FrameLayout) ((Activity) context).getWindow().getDecorView();mOriginalSystemUiVisibility = decor.getSystemUiVisibility();fullscreenContainer = new FrameLayoutFullscreenHolder(context);fullscreenContainer.addView(view, COVER_SCREEN_PARAMS);decor.addView(fullscreenContainer, COVER_SCREEN_PARAMS);customView = view;setStatusBarVisibility(false);customViewCallback = callback;// 隐藏系统UIint uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;decor.setSystemUiVisibility(uiOptions);// 添加慢慢弹出来的动画效果AnimationSet animSet = new AnimationSet(true);AlphaAnimation fadeIn = new AlphaAnimation(0.0f, 1.0f);fadeIn.setDuration(800);animSet.addAnimation(fadeIn);view.startAnimation(animSet);}/*** 隐藏视频全屏*/private void hideCustomView() {FrameLayout decor = (FrameLayout) ((Activity) context).getWindow().getDecorView();// 恢复系统UI的可见性decor.setSystemUiVisibility(mOriginalSystemUiVisibility);if (customView == null) {return;}setStatusBarVisibility(true);StatusBarCompat.setStatusBarDarkFont((Activity) context, true); // 状态栏字体颜色decor.removeView(fullscreenContainer);fullscreenContainer = null;customView = null;// 通知全屏播放已结束customViewCallback.onCustomViewHidden();}/*** 全屏容器界面*/static class FrameLayoutFullscreenHolder extends FrameLayout {public FrameLayoutFullscreenHolder(Context ctx) {super(ctx);setBackgroundColor(ctx.getResources().getColor(android.R.color.black));}@Overridepublic boolean onTouchEvent(MotionEvent evt) {return true;}}private void setStatusBarVisibility(boolean visible) {int flag = visible ? 0 : WindowManager.LayoutParams.FLAG_FULLSCREEN;((Activity) context).getWindow().setFlags(flag, WindowManager.LayoutParams.FLAG_FULLSCREEN);}}
