亮点是使用外部文件修改了触摸屏的触摸位置,导入动画效果nineoldandroids的jar包
其中需要注意的是布局文件中的android:name
<code class="language-html" hljs=""><relativelayout android:background="@drawable/qq" android:layout_height="match_parent" android:layout_width="match_parent"></relativelayout></code><b><code class="language-html" hljs=""><fragment android:id="@+id/id_left_menu" android:layout_gravity="left" android:layout_height="match_parent" android:layout_width="200dp" android:name="com.zhy.demo_zhy_17_drawerlayout.MenuLeftFragment" android:tag="LEFT"><fragment android:id="@+id/id_right_menu" android:layout_gravity="right" android:layout_height="match_parent" android:layout_width="100dp" android:name="com.zhy.demo_zhy_17_drawerlayout.MenuRightFragment" android:tag="RIGHT"></fragment></fragment></code></button>

效果图
简单讲解
1、为了模拟QQ的右侧菜单需要点击才能出现,所以在初始化DrawerLayout的时候,使用了mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT);意思是只有编程才能将其弹出,
双向滑动(...)
,电脑资料
《双向滑动(...)》(https://www.unjs.com)。然后在弹出以后,需要让手势可以滑动回去,所以在OpenRightMenu中又编写了:
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED,Gravity.RIGHT); UNLOCK了一下。
最后在onDrawerClosed回调中,继续设置mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED,Gravity.RIGHT);
2、动画效果
动画用了nineoldandroids,关于动画各种偏移量、缩放比例的计算请参考Android 高仿 QQ5.0 侧滑菜单效果 自定义控件来袭 基本是一致的,唯一的不同的地方,给Content设置了ViewHelper.setTranslationX(mContent, mMenu.getMeasuredWidth() * (1 - scale));让Content在菜单的右侧,默认情况下Menu在菜单之上,所以我们根据菜单划出的距离给Content设置X方向的偏移量。
好了,其实看到可以这么做,基本上任何的侧滑菜单效果都能写出来了。有兴趣的话,可以拿DrawerLayout实现这篇博客的所有效果:Android 实现形态各异的双向侧滑菜单 自定义控件来袭 。
3、setDrawerListener
通过代码也能看出来,可以使用setDrawerListener监听菜单的打开与关闭等等。这里对于当前操作是哪个菜单的判断是通过TAG判断的,我觉得使用gravity应该也能判断出来~~
