Load normally ：
Insert picture description here

Treatment method ：

 webView.setWebChromeClient(new WebChromeClient() {
    

            @Override
            public Bitmap getDefaultVideoPoster() {
    
                //modified by kxqin on 2020/7/17  load h5 video , Solve the problem of gray background and black triangle playing key 
                try{
    
                    // Default return null,  Replace here with a transparent picture , Does not affect playback .
                    return Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888);
                }catch(Exception e){
    
                    return super.getDefaultVideoPoster();
                }
            }
 }

tips： Repeated settings will overwrite the old , Because it's always new WebChromeClient, So use it on the outermost layer , The use of base classes may be covered by an outer layer , The pit has been stepped on .
