The sample code is written in RxJava + RxLifecycle + Data-Binding mode.

Example:

The implementation method is as follows:

1. import dependent Libraries

① RxJava: Reactive Extensions for the JVM

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

② RxLifecycle

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

③ Data-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 countdown

Public final class RxHelper {private RxHelper () {throw new AssertionError ();}/*** countdown */public static Observable <Integer> countdown (int time) {if (time <0) {time = 0;} final int countTime = time; return Observable. interval (0, 1, TimeUnit. SECONDS ). map (new Func1 <Long, Integer> () {@ Override public Integer call (Long increaseTime) {return countTime-increaseTime. intValue ();}}). take (countTime + 1 ). subscribeOn (Schedulers. io ()). unsubscribeOn (Schedulers. io ()). subscribeOn (AndroidSchedulers. mainThread ()). observeOn (AndroidSchedulers. mainThread ());}}

 

③ Custom method: Implement Asynchronous Loading

Private void init () {RxHelper. countdown (5 ). compose (this. <Integer> bindToLife ()). subscribe (new Subscriber <Integer> () {@ Override public void onCompleted () {doSkip () ;}@ Override public void onError (Throwable e) {doSkip ();} @ Override public void onNext (Integer integer) {mBinding. sbSkip. setText ("Skip" + integer );}});}

 

④ Custom method: Achieve redirection

private void doSkip() {    if (!mIsSkip) {        mIsSkip = true;        finish();        startActivity(new Intent(SplashActivity.this, MainActivity.class));        overridePendingTransition(R.anim.hold, R.anim.zoom_in_exit);    }}

 

⑤ Set the topic style to full screen

<style name="SplashTheme" parent="Theme.AppCompat.Light.NoActionBar">    <item name="colorPrimary">@color/colorPrimary</item>    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>    <item name="colorAccent">@color/colorAccent</item>    <item name="android:windowFullscreen">true</item></style>
