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ActionBar
    hideSupportActionBar(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();
    }
