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...
下面是Activity

} }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！
<!--私聊--> <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。
