1 清单文件中的WebView添加下面两行的代码

android:hardwareAccelerated="true"android:configChanges="orientation|keyboardHidden"复制代码

2 加入下面的代码，并且调用方法

MyChromeClient chromeClient = new MyChromeClient();webView.setWebChromeClient(chromeClient);复制代码

3 WebView外面套一层

                        
                         
                     
    复制代码

3 重写WebView的返回键

@Override    public boolean onKeyDown(int keyCode, KeyEvent event) {        if (event.getAction() == KeyEvent.ACTION_DOWN) {            switch (keyCode) {                case KeyEvent.KEYCODE_BACK:                    if (webView != null) {                        //关闭视频View                        chromeClient.onHideCustomView();                    } else {                        //WebView返回:goBack()                    }                    return true;            }        }        return super.onKeyDown(keyCode, event);    }复制代码

源码

private View myView = null;private WebChromeClient.CustomViewCallback myCallBack = null; public class MyChromeClient extends WebChromeClient {        @Override        public void onShowCustomView(View view, CustomViewCallback callback) {            if (myView != null) {                callback.onCustomViewHidden();                return;            }            webViewFrameLayout.removeView(webView);            webViewFrameLayout.addView(view);            myView = view;            myCallBack = callback;        }        @Override        public void onHideCustomView() {            if (myView == null) {                return;            }            webViewFrameLayout.removeView(myView);            myView = null;            webViewFrameLayout.addView(webView);            myCallBack.onCustomViewHidden();        }        @Override        public boolean onConsoleMessage(ConsoleMessage consoleMessage) {            // TODO Auto-generated method stub            return super.onConsoleMessage(consoleMessage);        }    }复制代码
