Android webview 退出时关闭声音 4.视频全屏 添加cookie

全屏问题，可以参考 http://bbs.csdn.net/topics/390839259，点击

webView = (WebView) findViewById(R.id.webView);
		videoview = (FrameLayout) findViewById(R.id.video_view);
		chromeClient = new WebChromeClient() {

			// 播放网络视频时全屏会被调用的方法
			@Override
			public void onShowCustomView(View view, CustomViewCallback callback) {
				if (islandport) {
					return;
				}
				setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
				// if (myCallback != null) {
				// myCallback.onCustomViewHidden();
				// myCallback = null;
				// return;
				// }
				webView.setVisibility(View.GONE);
				if (myView != null) {
					callback.onCustomViewHidden();
					return;
				}

				videoview.addView(view);
				myView = view;
				myCallback = callback;
				videoview.setVisibility(View.VISIBLE);
			}

			private View myView = null;
			private CustomViewCallback myCallback = null;

			public void onHideCustomView() {
				if (myView == null) {
					return;
				} else {
					// if (myCallback != null) {
					// myCallback.onCustomViewHidden();
					// myCallback = null;
					// }
					setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
					myView.setVisibility(View.GONE);
					videoview.removeView(myView);
					videoview.setVisibility(View.GONE);
					webView.setVisibility(View.VISIBLE);
					myCallback.onCustomViewHidden();
					myView = null;

				}
			}

			@Override
			public void onReceivedTitle(WebView view, String title) {
				// TODO Auto-generated method stub
				super.onReceivedTitle(view, title);
				if (showtitle) {
					setTitle(title);
				}
			}
		};
		WebSettings setting = webView.getSettings();
		setting.setBuiltInZoomControls(false);
		setting.setUseWideViewPort(true);
		setting.setLoadWithOverviewMode(true);
		setting.setCacheMode(WebSettings.LOAD_NO_CACHE);

		setting.setPluginState(PluginState.ON_DEMAND);
		// setting.setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN); //支持内容重新布局
		setting.setJavaScriptEnabled(true);
		setting.setJavaScriptCanOpenWindowsAutomatically(true);

　　注意旋转屏幕

android:configChanges="orientation|keyboardHidden|screenSize"

	/**
	 * 当横竖屏切换时会调用该方法

	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);

		if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
			islandport = true;
		} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
			islandport = false;
		}
	}
