優化fm.jiecao.jcvideoplayer_lib中視頻橫豎屏自動適配原視頻方案：

僅優化關鍵代碼部分，源碼：

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();}}

優化

詳細方案

• 隱藏ActionBar: 在全屏模式下，通常需要隱藏ActionBar以提供更好的觀看體驗。

• 獲取屏幕尺寸: 使用WindowManager獲取當前設備的屏幕寬度和高度。

• 視頻尺寸判斷:?通過JCMediaManager獲取當前視頻的寬度和高度，并根據寬高比決定是橫屏還是豎屏。

• 布局參數設置: 根據視頻的寬高比，設置FrameLayout.LayoutParams以確保視頻在全屏模式下正確顯示。

• 旋轉設置: 如果視頻寬度大于高度，旋轉90度以橫屏顯示；否則，保持豎屏。

• 添加視圖和設置參數: 將新的JCVideoPlayer實例添加到視圖中，并設置相關參數和動畫。

• 異常處理: 捕獲并處理可能的異常，以確保程序的健壯性。
