難以理解爲什麼我的圖像視圖閃爍

我已經設置了兩行水平滑動動畫的四個圖像瀏覽，頂部圖像滑動到右側，底部向左滑動，我很想知道爲什麼我的圖像眨眼當他們動畫時，我會向任何有想法的人提供任何見解，謝謝！難以理解爲什麼我的圖像視圖閃爍

不看你的代碼：你使用雙緩衝？ –

我不熟悉doublebuffering – user1091368

後快速谷歌搜索我假設你建議它可能抵消閃爍 – user1091368

偶然發現瞭解決方案，在我SetImgPos功能...

layoutPositioner.bottomMargin = (int) offsetY - (y_Margin - theView.getHeight()); 
layoutPositioner.rightMargin = (int) offsetX - (x_Margin - theView.getWidth());

顯然太多我的應用程序也處理和其更改爲...

layoutPositioner.bottomMargin = (int) offsetY - (int) (y_Margin - height); 
layoutPositioner.rightMargin = (int) offsetX - (int) (x_Margin - width);

刪除了閃爍
