A Light Event Bus For Android. 轻量级事件发布/订阅框架,支持生命周期感知,支持粘性事件,支持绑定TAG,支持绑定View,可传递多个参数。
implementation ' com.github.Z-P-J:ZBus:1.0.0'
// 订阅自定义的Event类型事件
ZBus .with (LifecycleOwner )
.observe (Event .class )
.bindTag ("TAG" ) // 绑定TAG,可根据该TAG移除订阅
.bindView (tvText ) // 绑定View,当View销毁时自动取消订阅
.bindLifecycle (Owner , Lifecycle .Event .ON_PAUSE ) // 绑定Activity/Fragment生命周期
.doOnAttach (new Runnable () {
@ Override
public void run () {
// 开始监听
}
})
.doOnChange (new Consumer <Event >() {
@ Override
public void accept (Event event ) {
// 接收Event类型的信息
}
})
.doOnDetach (new Runnable () {
@ Override
public void run () {
// 移除监听
}
})
.subscribe ();
// 发送Event类型事件
ZBus .post (new Event ());
// 订阅Key事件
ZBus .with (lifecycleOwner )
.observe ("Key" )
.doOnChange (new Consumer <String >() {
@ Override
public void accept (String s ) throws Exception {
// 收到信息
}
})
.subscribe ();
// 发送Key事件
ZBus .post ("Key" );
3. 订阅和发送Key and Event类型事件
// 订阅者1:订阅Key1和Boolean类型事件
ZBus .with (lifecycleOwner )
.observe ("Key1" , Boolean .class )
.doOnChange (new SingleConsumer <Boolean >() {
@ Override
public void onAccept (Boolean event ) throws Exception {
// 收到event1
}
})
.subscribe ();
// 订阅者2:订阅Key2和Boolean类型事件
ZBus .with (lifecycleOwner )
.observe ("Key2" , Boolean .class )
.doOnChange (new SingleConsumer <Boolean >() {
@ Override
public void onAccept (Boolean event ) throws Exception {
// 收到event
}
})
.subscribe ();
// 订阅者3:订阅Key1和Integer类型事件
ZBus .with (lifecycleOwner )
.observe ("Key1" , Integer .class )
.doOnChange (new SingleConsumer <Integer >() {
@ Override
public void onAccept (Integer event ) throws Exception {
// 收到event
}
})
.subscribe ();
// 发送Key and Event事件
ZBus .post ("Key1" , true ); // 订阅者1将收到事件
ZBus .post ("Key2" , false ); // 订阅者2将收到事件
ZBus .post ("Key1" , 1 ); // 订阅者3将收到事件
// 当我们要同时传送两个参数时我们无需自定义新的Event类,可直接使用以下方法
ZBus .with (lifecycleOwner )
.observe ("Key" , Boolean .class , Integer .class )
.doOnChange (new ZBus .PairConsumer <Boolean , Integer >() {
@ Override
public void onAccept (Boolean b , Integer i ) {
// 收到信息: b=true and i=100
}
})
.subscribe ();
// 发送Key事件
ZBus .post ("Key" , true , 100 );
// 当我们要同时传送三个参数时我们无需自定义新的Event类,可直接使用以下方法
ZBus .with (lifecycleOwner )
.observe ("Key" , String .class , Boolean .class , Double .class )
.doOnChange (new ZBus .TripleConsumer <String , Boolean , Integer >() {
@ Override
public void onAccept (String s , Boolean b , Double d ) {
// 收到信息: s="msg" and b=false and d=100.0
}
})
.subscribe ();
// 发送数据
ZBus .post ("Key" , "msg" , false , 100.0 );
// 注意:若发送以下数据上面的订阅者将接收不到,第三个参数必须是Double类型才能接收到
ZBus .post ("Key" , "msg" , false , 100 );
/*
支持Sticky事件,ZBus.withSticky和ZBus.postSticky,其他用法同上
*/
// 订阅Sticky事件
ZBus .withSticky ()
.observe (...)
// 发送Sticky事件
ZBus .postSticky (...);
// 获取Sticky事件
ZBus .getStickyEvent ("key" );
ZBus .getStickyEvent (clazz );
ZBus .getStickyEvent ("key" , clazz );
// 移除Sticky事件
ZBus .removeStickyEvent ("key" );
ZBus .removeStickyEvent (clazz );
ZBus .removeStickyEvent ("key" , clazz );
ZBus .removeAllStickyEvents ();
/*
订阅者1、2和3都依赖于object1,订阅者4依赖于object2
*/
// 订阅者1
ZBus .with (object1 )
.observe ("Key1" , Event1 .class )
.bindTag ("TAG1" ) // 绑定TAG,可根据该TAG移除订阅
.bindView (bindView ) // 绑定View,当View销毁时自动取消订阅
.bindLifecycle (this , Lifecycle .Event .ON_PAUSE ) // 绑定Activity / Fragment的onPause生命周期
.bindLifecycle (this ) // 绑定Activity / Fragment生命周期,默认为onDestroy时移除取消订阅
.subscribe ();
// 订阅者2
ZBus .wtih (object1 )
.observe ("Key2" , Event1 .class )
.bindTag ("TAG2" )
.subscribe ();
// 订阅者3
ZBus .with (object1 )
.observe ("Key1" , Event2 .class )
.bindTag ("TAG3" )
.subscribe ();
// 订阅者4
ZBus .with (object2 )
.observe ("Key1" , Event2 .class )
.bindTag ("TAG3" )
.subscribe ();
// 移除bindView,当bindView调用onViewDetachedFromWindow时将自动取消订阅者1
view .removeView (bindView );
// 当Activity/Fragment onPause时将自动取消订阅者1
onPause ();
// 根据依赖的Object取消订阅
ZBus .removeObservers (object1 ); // 订阅者1、订阅者2和订阅者3都会被取消
ZBus .removeObservers (object2 ); // 只取消订阅者4
// 根据TAG取消订阅
ZBus .removeObservers ("TAG1" ); // 只取消订阅者1
ZBus .removeObservers ("TAG2" ); // 只取消订阅者2
ZBus .removeObservers ("TAG3" ); // 将取消订阅者3和订阅者4
// 根据Key取消订阅
ZBus .removeObservers ("Key1" ); // 将取消订阅者1、订阅者3和订阅者4
ZBus .removeObservers ("Key2" ); // 只取消订阅者2
