本文介绍了SlidingPanelLayout在android中从右到左效果不佳的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在从右到左创建 SlidingPanelLayout 以实现 filter 的目的。面板可以很好地从右侧出来并进行动画处理，但是当动画停止时，它直接移到左侧，但是我希望该比率为70％，这意味着右侧面板显示了总屏幕的70％，当再次单击它时
I am creating SlidingPanelLayout from right to left for the filter purpose.The panel work fine it come out from right side and does animation but when Animation is stop it directly go to left side full but I want the ratio is 70% means right side panel came out 70% of the total screen and when click again it goes to hind and full Activity is display.
第一次停止动画时，侧面板位于屏幕截图的左侧，但我希望它位于右侧。
When first time Animation is stop the side panel goes to left side in the screenshot .But I want it right side.
屏幕截图：
但是我要显示它的写面，当再次单击时它将在右边再次隐藏。
but i want to display it write side and when click again it will go right side and hide again.
