要实现的就是这个样子，输入后加号变成发送，但具体实现时发现普通办法并不能让软键盘和输入框还有window和谐相处，相信遇到的人一定深有体会，相机相册那个view显示时会闪烁，然后各种问题，恩，只能另外寻找办法...

        if (linRoot != null)

    }
}

核心就是onLayoutChange监听，与点击事件一起协调控制软键盘、输入框、相机选项view的显示，linRoot是根布局，至于为什么不用getWindow？这个自己试试就知道了，最后记得回收监听，哦，manifest！

<activity
    android:name="com.vct.im.PrivateChatActivity"
    android:screenOrientation="portrait"
    android:theme="@style/Theme.AppCompat.Light.DarkActionBar"
    android:windowSoftInputMode="stateHidden" />

只stateHidden就可以了，会挤压window的adjustPan什么的，不要。
