The sample code is written in RxJava + rxlifecycle + data-binding mode

Example diagram:

Words do not say much, the implementation of the following way:

1. Importing dependent libraries

①rxjava:reactive Extensions for the JVM

Compile ' io.reactivex:rxjava:1.2.9 ' compile ' io.reactivex:rxandroid:1.2.1 '

②rxlifecycle

Compile ' com.trello:rxlifecycle:1.0 ' compile ' com.trello:rxlifecycle-components:1.0 '

③data-binding

dataBinding {    enabled = true}

2. Code writing (key code)

① Custom Interface View

 Public Interface Baseview {    <T> lifecycletransformer<t> bindtolife ();}

② Create a helper class for the countdown operation

 Public Final classRxhelper {PrivateRxhelper () {Throw NewAssertionerror (); }    /*** Countdown*/     Public StaticObservable<integer> Countdown (intTime ) {        if(Time < 0) { time= 0; }        Final intCounttime =Time ; returnObservable.interval (0, 1, Timeunit.seconds). Map (NewFunc1<long, integer>() {@Override PublicInteger Call (Long increasetime) {returnCounttime-Increasetime.intvalue (); }}). Take (Counttime+ 1). Subscribeon (Schedulers.io ()). Unsubscribeon (Schedulers.io ()). Subscrib    EOn (Androidschedulers.mainthread ()). Observeon (Androidschedulers.mainthread ()); }}

③ Custom Method: Implementing Asynchronous loading

Private voidinit () {Rxhelper.countdown (5). Compose ( This.<integer>Bindtolife ()). Subscribe (NewSubscriber<integer>() {@Override Public voidoncompleted () {doskip (); } @Override Public voidOnError (Throwable e) {doskip (); } @Override Public voidonNext (Integer integer) {mBinding.sbSkip.setText ("Skip" +integer); }            });}

④ Custom method: Implement Jump

Private void Doskip () {    if (!  Misskip) {        true;        Finish ();        StartActivity (new Intent (splashactivity.  this, mainactivity. class ));        Overridependingtransition (R.anim.hold, r.anim.zoom_in_exit);}    }

⑤ set theme styles to fullscreen

<stylename= "Splashtheme"Parent= "Theme.AppCompat.Light.NoActionBar">    <Itemname= "Colorprimary">@color/colorprimary</Item>    <Itemname= "Colorprimarydark">@color/colorprimarydark</Item>    <Itemname= "Coloraccent">@color/coloraccent</Item>    <Itemname= "Android:windowfullscreen">True</Item></style>
