android webView无法全屏播放视频

使用：webview.setWebChromeClient(new MyWebChromeClient());

/**处理观看视频点击全屏、退出全屏操作
 *
 * 主要通过重写 onShowCustomView 和onHideCustomView,首先通过onShowCustomView中的内容view加入到全屏时的view中
 * ,然后再把webview从view中移除.然后在退出全屏时,在onHideCustomView中把webview加回到父view中,并且移除和隐藏全屏的view.

class MyWebChromeClient extends WebChromeClient {
    private View myView = null;

    @Override
    public void onProgressChanged(WebView view, int newProgress) {
        if (newProgress == 100) {
            progressBar1.setVisibility(View.GONE);//加载完网页进度条消失
        } else {
            progressBar1.setVisibility(View.VISIBLE);//开始加载网页时显示进度条
            progressBar1.setProgress(newProgress);//设置进度值
        }
    }

    // 全屏
    @Override
    public void onShowCustomView(View view, CustomViewCallback callback) {
        super.onShowCustomView(view, callback);
        ViewGroup parent = (ViewGroup) webview.getParent();
        parent.removeView(webview);

        videoView.addView(view);
        videoView.setVisibility(View.VISIBLE);
        myView = view;
        setFullScreen();
    }

    // 退出全屏
    @Override
    public void onHideCustomView() {
        super.onHideCustomView();
        if (myView != null) {
            videoView.removeAllViews();

            myView = null;
            quitFullScreen();
        }
    }

private void setFullScreen() {
