我可以使用触摸事件的这个动画。

              if (event.getAction()==MotionEvent.ACTION_MOVE) {

                  x=event.getX();
                  RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(300, 60);
                  params.leftMargin = (int)x;

                  btnDeclinecall.setLayoutParams(params);

                           }

                return false;
            }

我用上面的codeS，但它不为我工作。

i use the above codes but it doesn't work for me

推荐答案

请参阅该code在 Android的锁屏滑块

供参考：这不是我的code，它是从Android的Froyo的来源$ C ​​$ C。 我也一直在使用code从上述位置创建滑块在我的应用程序，但是，这是正确的滑块，是因为你需要左边的滑块我不能张贴code。

FYI:This is not my code, it is from android froyo source code. I also had created the slider in my app using code from above location but that was right slider, So i cant post that code because you need left slider.

所以只要复制左边的滑块部分从上面的链接，并使用它了解甚少。

so just copy Left slider part from above link and use it with little understanding.

注：

上面的链接包含最优化$ C $下滑块（但它同时包含左，右滑块）。

Above link contain the best and optimized code for slider(But it contain both left and right slider).

所以不要浪费时间在其他地方，它可能看起来有点艰难的开始，但相信我只是试着去了解使用私人滑块mLeftSlider; 在上面的链接，这将导致你到你的目的地。

so don't waste time anywhere else, It may look little tough in starting but Trust me just try to understand use of private Slider mLeftSlider;in the above link and that will lead you to your destination.
