webview播放视频之后，js弹框弹出失败，实际屏幕是暗色的，说明弹框已经弹出，怀疑是x5内核自己实现的全屏出现冲突，所以改为自己实现全屏播放处理

播放视频建议使用腾讯x5内核

 /**
     * 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 Context mContext;
    private WebView mWebView;
    private LoadingDialog mLoadingDialog;
    private boolean mShowLoading = true;
    private IWebView.OnErrorListener mOnErrorListener;
    private OnPageListener mOnPageListener;
    private View customView;
    private FrameLayout fullscreenContainer;
    private IX5WebChromeClient.CustomViewCallback mCustomViewCallback;
    private FrameLayout mRoot;

添加监听
 wv.setWebChromeClient(new WebChromeClient() {
 
             //消失全屏时自己处理
            @Override
            public void onHideCustomView() {

                KLog.d(Constant.TTAG, "处理全屏");
                if (customView == null) {
                    return;
                }
                KLog.d(Constant.TTAG, "处理全屏");
                FrameLayout decor = (FrameLayout) ((Activity) mContext).getWindow().getDecorView();

                if (fullscreenContainer != null) {
                    fullscreenContainer.removeAllViews();
                    decor.removeView(fullscreenContainer);
                }
                fullscreenContainer = null;
                customView = null;
                mCustomViewCallback.onCustomViewHidden();
                wv.setVisibility(View.VISIBLE);
            }

            //点击全屏时自己处理
            @Override
            public void onShowCustomView(View view, IX5WebChromeClient.CustomViewCallback customViewCallback) {

                KLog.d(Constant.TTAG, "处理全屏");

                if (customView != null) {
                    customViewCallback.onCustomViewHidden();
                    return;
                }

                FrameLayout decor = (FrameLayout) ((Activity) mContext).getWindow().getDecorView();
                fullscreenContainer = new FullscreenHolder(mContext);
                fullscreenContainer.addView(view, COVER_SCREEN_PARAMS);
                decor.addView(fullscreenContainer, COVER_SCREEN_PARAMS);
                customView = view;
                mCustomViewCallback = customViewCallback;
            }
        });
