优化fm.jiecao.jcvideoplayer_lib中视频横竖屏自动适配原视频方案：

仅优化关键代码部分，源码：

public void startWindowFullscreen() {Log.i(TAG, "startWindowFullscreen " + " [" + this.hashCode() + "] ");hideSupportActionBar(getContext());ViewGroup vp = (ViewGroup) (JCUtils.scanForActivity(getContext())).findViewById(Window.ID_ANDROID_CONTENT);View old = vp.findViewById(FULLSCREEN_ID);if (old != null) {vp.removeView(old);}if (textureViewContainer.getChildCount() > 0) {textureViewContainer.removeAllViews();}try {Constructor<JCVideoPlayer> constructor = (Constructor<JCVideoPlayer>) JCVideoPlayer.this.getClass().getConstructor(Context.class);JCVideoPlayer jcVideoPlayer = constructor.newInstance(getContext());jcVideoPlayer.setId(FULLSCREEN_ID);WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);int w = wm.getDefaultDisplay().getWidth();int h = wm.getDefaultDisplay().getHeight();FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(h, w);lp.setMargins((w - h) / 2, -(w - h) / 2, 0, 0);vp.addView(jcVideoPlayer, lp);jcVideoPlayer.setShowDownloadIcon(showDownloadIcon);if (needSumWatchVideoTimerLongFlag) {jcVideoPlayer.setUpWithWatchVideoTime(videoId, url, JCVideoPlayerStandard.SCREEN_WINDOW_FULLSCREEN, objects);} else {jcVideoPlayer.setUp(videoId, url, JCVideoPlayerStandard.SCREEN_WINDOW_FULLSCREEN, objects);}jcVideoPlayer.setUiWitStateAndScreen(currentState);jcVideoPlayer.addTextureView();jcVideoPlayer.setRotation(90);final Animation ra = AnimationUtils.loadAnimation(getContext(), R.anim.start_fullscreen);jcVideoPlayer.setAnimation(ra);JCVideoPlayerManager.setLastListener(this);JCVideoPlayerManager.setListener(jcVideoPlayer);downloadButton.setVisibility(showDownloadIcon ? VISIBLE : View.GONE);} catch (InstantiationException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}}

优化

详细方案

隐藏ActionBar: 在全屏模式下，通常需要隐藏ActionBar以提供更好的观看体验。

获取屏幕尺寸: 使用WindowManager获取当前设备的屏幕宽度和高度。

视频尺寸判断: 通过JCMediaManager获取当前视频的宽度和高度，并根据宽高比决定是横屏还是竖屏。

布局参数设置: 根据视频的宽高比，设置FrameLayout.LayoutParams以确保视频在全屏模式下正确显示。

旋转设置: 如果视频宽度大于高度，旋转90度以横屏显示；否则，保持竖屏。

添加视图和设置参数: 将新的JCVideoPlayer实例添加到视图中，并设置相关参数和动画。

异常处理: 捕获并处理可能的异常，以确保程序的健壮性。

代码：

public void startWindowFullscreen() {Log.i(TAG, "startWindowFullscreen " + " [" + this.hashCode() + "] ");// 隐藏支持的ActionBarhideSupportActionBar(getContext());// 获取当前Activity的内容视图ViewGroup vp = (ViewGroup) (JCUtils.scanForActivity(getContext())).findViewById(Window.ID_ANDROID_CONTENT);View old = vp.findViewById(FULLSCREEN_ID);if (old != null) {vp.removeView(old); // 移除旧的全屏视图}if (textureViewContainer.getChildCount() > 0) {textureViewContainer.removeAllViews(); // 移除TextureView容器中的所有视图}try {// 通过反射创建一个新的JCVideoPlayer实例Constructor<JCVideoPlayer> constructor = (Constructor<JCVideoPlayer>) JCVideoPlayer.this.getClass().getConstructor(Context.class);JCVideoPlayer jcVideoPlayer = constructor.newInstance(getContext());jcVideoPlayer.setId(FULLSCREEN_ID); // 设置全屏视图的ID// 获取屏幕的宽度和高度WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);int screenWidth = wm.getDefaultDisplay().getWidth();int screenHeight = wm.getDefaultDisplay().getHeight();// 获取视频的宽度和高度int videoWidth = JCMediaManager.instance().currentVideoWidth;int videoHeight = JCMediaManager.instance().currentVideoHeight;FrameLayout.LayoutParams lp;// 根据视频的宽高比设置布局参数和旋转角度if (videoWidth > videoHeight) {// 如果视频宽度大于高度，设置为横屏lp = new FrameLayout.LayoutParams(screenHeight, screenWidth);lp.setMargins((screenWidth - screenHeight) / 2, -(screenWidth - screenHeight) / 2, 0, 0);jcVideoPlayer.setRotation(90); // 旋转90度} else {// 如果视频高度大于或等于宽度，设置为竖屏lp = new FrameLayout.LayoutParams(screenWidth, screenHeight);jcVideoPlayer.setRotation(0); // 不旋转}// 将新的JCVideoPlayer添加到视图中vp.addView(jcVideoPlayer, lp);// 设置视频播放器的参数jcVideoPlayer.setUp(url, JCVideoPlayerStandard.SCREEN_WINDOW_FULLSCREEN, objects);jcVideoPlayer.setUiWitStateAndScreen(currentState); // 设置UI状态和屏幕jcVideoPlayer.addTextureView(); // 添加TextureView// 设置全屏动画final Animation ra = AnimationUtils.loadAnimation(getContext(), R.anim.start_fullscreen);jcVideoPlayer.setAnimation(ra);// 设置视频播放器管理器的监听器JCVideoPlayerManager.setLastListener(this);JCVideoPlayerManager.setListener(jcVideoPlayer);} catch (InstantiationException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}
