本文介绍了SlidingPanelLayout 在 android 中从右到左无法正常工作的处理方法，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 用于 filter 目的.面板工作正常，它从右侧出来并执行动画，但是当动画直接停止时转到左侧完整但我希望比例为 70% 意味着 右侧面板出现总屏幕的 70% 再次单击时，它会转到后部并显示完整的活动.
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.
当第一次动画停止时，侧面板在屏幕截图中转到左侧.但我想要右侧.
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:
但我想显示它写的一面，当再次点击它会向右转并再次隐藏.
but i want to display it write side and when click again it will go right side and hide again.
