最近更新了微信版本到6.2，发现里面有个非常好的体验，就是在第二个页面Activity能手势向右滑动返回，在手势滑动的过程中能看到第一个页面，这种体验非常赞，这里高仿了一下。这里使用的是v4包里面的SlidingPaneLayout来手势滑动，在下一篇博文中将采用SlidingMenu来高仿，下面是SlidingPaneLayout高仿后的效果，效果还是蛮不错的。
最重要的是，每一个页面都是Activity，而非Fragment哦，使用Activity和正常的Activity一样
这里给出demo下载地址github
下面讲一下实现的原理，里面有几个难点需要说一下
- 手势滑动
- 在滑动过程中看到第一个页面内容
解决方案：
- 手势滑动借用了v4包里面的SlidingPaneLayout，因为这个SlidingPaneLayout效果和我们要实现的效果非常像，所以就想着通过这个来改造，SlidingPaneLayout帮我们已经处理好了手势事件
- 在滑动过程中看到下面的Activity页面就非常简单了，只要把我们当前的Activity样式设置成透明就OK了
下面一步一步来讲解实现原理：
首先第一步：因为我们有的页面需要滑动返回，有的页面不需要滑动返回，所以这里抽取了一个父类BaseSwipeBackActivity，在你项目里需要加手势滑动返回的Activity，你只要继承BaseSwipeBackActivity就可以了，不需要的不用继承它。
这里先看一下BaseSwipeBackActivity的源码实现：

随着手势滑动，慢慢的显示出菜单，因为整个Activity是透明的，左侧菜单也是透明的，这样就可以透过左侧菜单看到下面的Activity页面，当左侧菜单完全打开后，我们要结束掉这个Activity，这里监听了SlidingPaneLayout的public void onPanelOpened(View view)方法，这个方法的意思就是菜单打开后执行的操作，我这里重写了这个方法，看代码如下：
<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"> <span class="hljs-annotation" style="color: rgb(155, 133, 157); box-sizing: border-box;">@Override</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> <span class="hljs-title" style="box-sizing: border-box;">onPanelOpened</span>(View view) { <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//菜单打开后，我们结束掉这个Activity</span> finish(); <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">this</span>.overridePendingTransition(<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>, R.anim.slide_out_right); }</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>让菜单打开后结束掉这个Activity，这样就实现了手势滑动返回上一个页面
这样我们的BaseSwipeBackActivity就写好了，那怎么来用呢，这里我们创建一个NextActivity，继承之BaseSwipeBackActivity，其他的和普通的Activity都一样，看源码实现，其实非常简单：
