RxBinding2（一）基础库组件
RxBinding绑定View事件
通过RxBinding我们可以将View的事件转化为事件流，然后就可以采用RxJava发射事件流，操作符进行操作。

RxBinding2（二）MaterialDesign系列
RxBinding2（三）Support-V4库和RecyclerView
全部依赖库support支持：
//基础库
implementation 'com.jakewharton.rxbinding2:rxbinding:2.2.0'
implementation 'com.jakewharton.rxbinding2:rxbinding-design:2.2.0'
implementation 'com.jakewharton.rxbinding2:rxbinding-recyclerview-v7:2.2.0'
//V4,V7对应于android的V4，V7包组件
implementation 'com.jakewharton.rxbinding2:rxbinding-support-v4:2.2.0'
implementation 'com.jakewharton.rxbinding2:rxbinding-appcompat-v7:2.2.0'
//电视相关
implementation 'com.jakewharton.rxbinding2:rxbinding-leanback-v17:2.2.0'
每一个rxbinding2依赖库都以一个xxx-kotlin支持版本
settings.gragle中include ':app', ':rxbinding'
实战：
全部RxView事件，注意防内存泄漏，要么将订阅添加到CompositeDisposable，在onDestory中clear，要么采用RxLifecycle控制生命周期。
xxxEvent：因RxJava方法只有一个参数，所以xxxEvent里面封装了多个参数的情况。
handle：返回false则拦截事件，不发送事件
//基础库可以得到基础组件

举几个例子
//View被添加时触发
RxView.attaches(mView)
.subscribe(new Consumer<Object>() {
@Override
public void accept(Object o) {
}
});
//View被添加时触发Events中封装了view
RxView.attachEvents(mView)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer<ViewAttachEvent>() {
@Override
public void accept(ViewAttachEvent viewAttachEvent) throws Exception {
//viewAttachEvent里面封装了View
viewAttachEvent.getView();
}
});
//点击事件
RxView.clicks(mView)
.throttleFirst(1, TimeUnit.SECONDS)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer<Object>() {
@Override
public void accept(Object o) {
}
});
//被拖拽
RxView.drags(mView)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Consumer<DragEvent>() {
@Override
public void accept(DragEvent dragEvent) throws Exception {
//DragEvent封装了各种参数
dragEvent.describeContents();
dragEvent.getAction();

});
//组件布局参数发生改变
RxView.layoutChangeEvents(mView)
.subscribe(new Consumer<ViewLayoutChangeEvent>() {
@Override
public void accept(ViewLayoutChangeEvent viewLayoutChangeEvent) throws Exception {
//ViewLayoutChangeEvent封装的参数
viewLayoutChangeEvent.getBottom();
viewLayoutChangeEvent.getLeft();
