Android Webview中的视屏全屏功能实现

Webview中的视屏全屏的时候是会出现问题的，我们对其做如下的修改：

1. 设置webview的WebChromeClient

WebSettings webSettings = mWebview.getSettings();
mWebview.setWebChromeClient(new MyWebChromeClient());

2. 重写WebChromeClient的onShowCustomView和onHideCustomView方法

    class MyWebChromeClient extends WebChromeClient {
        private View myView = null;

        // 全屏
        @Override
        public void onShowCustomView(View view, CustomViewCallback callback) {
            super.onShowCustomView(view, callback);

            ViewGroup parent = (ViewGroup) mWebview.getParent();
            parent.removeView(mWebview);

            // 设置背景色为黑色
            view.setBackgroundColor(mActivity.getResources().getColor(R.color.black));
            parent.addView(view);
            myView = view;

            setFullScreen();
            titleBar.setVisibility(View.GONE);

        }

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

                ViewGroup parent = (ViewGroup) myView.getParent();
                parent.removeView(myView);
                parent.addView(mWebview);
                myView = null;

                titleBar.setVisibility(View.VISIBLE);
                quitFullScreen();
            }
        }
    }
     /**
     * 设置全屏
     */
    private void setFullScreen() {
        // 设置全屏的相关属性，获取当前的屏幕状态，然后设置全屏
        mActivity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }

    /**
     * 退出全屏
     */
    private void quitFullScreen() {
        // 声明当前屏幕状态的参数并获取
        final WindowManager.LayoutParams attrs = mActivity.getWindow().getAttributes();
        attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
        mActivity.getWindow().setAttributes(attrs);
        mActivity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
    }

以上。
