WebView内部报空指针：解决方法是重写

WebChromeClient中的ge

getDefaultVideoPoster方法，返回默认图片就可以了

class MyWebChromClient extends WebChromeClient{
    @Override
    public Bitmap getDefaultVideoPoster() {
        try{
            //这个地方是加载h5的视频列表 默认图   点击前的视频图
            LogUtil.w("全网搜索","   加载视频默认图片");
            return BitmapFactory.decodeResource(getApplicationContext().getResources(),
                    R.drawable.icon_default);

        }catch(Exception e){
            LogUtil.w("全网搜索","   加载视频默认图片失败,,,,,,,,,,,,,");
            return super.getDefaultVideoPoster();
        }

    }
}
