RxJava and Rxandroid Four (use of rxbinding)

Students who are unfamiliar with Rxjava can read the articles I wrote before.

RxJava and Rxandroid One (basic)
RxJava and Rxandroid II (use of Operators)
RxJava and Rxandroid III (Life cycle control and memory optimization)

Also recommend a few good articles, to help understand Rxjava
How the Android client uses the RxJava
Implement an Event Bus–rxbus with RxJava

Preface : Rxbinding is an open source library of Jake Wharton, which provides a set of Rxjava-based Binding APIs on the Android platform. The so-called binding is the API for registering binding objects such as setting Onclicklistener, setting Textwatcher.

second, the use of Androidstudio

The general package is used below

Compile ' com.jakewharton.rxbinding:rxbinding:0.4.0 '

Third, code example

• Button Anti-shake processing

   Button = (button) Findviewbyid (R.ID.BT); Rxview.clicks (Button). Throttlefirst (2, Timeunit.seconds)//Two seconds to take only one click event, anti-shake operation. Subscribe (n EW action1<void> () {@Override public void call (void aVoid) {to                 Ast.maketext (Mainactivity.this, "clicked", Toast.length_short). Show (); }             }) ;

• Long-press-time monitoring of the button

   button = (Button) findViewById( R.id.bt ) ; //监听长按时间 RxView.longClicks( button)      .subscribe(new Action1<Void>() {          @Override         public void call(Void aVoid) {         Toast.makeText(MainActivity.this, "long click  ！！", Toast.LENGTH_SHORT).show();         }     }) ;

• ListView Click events, long press event handling

  ListView = (ListView) Findviewbyid (R.id.listview);     list<string> list = new arraylist<> ();     for (int i = 0; i < i++) {List.add ("SSS" + i); } Final Arrayadapter<string> adapter = new Arrayadapter<string> (this, Android.     R.layout.simple_expandable_list_item_1); Adapter.addall (list); Listview.setadapter (adapter);         Item Click event Rxadapterview.itemclicks (ListView). Subscribe (New action1<integer> () {@Override public void Call (Integer integer) {toast.maketext (Listactivity.this, "item Click" + Integer, Toast.length             _short). Show (); }         }) ;         Item Long click Rxadapterview.itemlongclicks (ListView). Subscribe (New action1<integer> () {@Override public void Call (Integer integer) {toast.maketext (Listactivity.this, "Item long click" + Integer, T Oast.             Length_short). Show (); }         }) ;

-User Login screen, tick the consent privacy agreement, the login button will be highlighted  

button = (Button) findViewById( R.id.login_bt );checkBox = (CheckBox) findViewById( R.id.checkbox );RxCompoundButton.checkedChanges( checkBox )    .subscribe(new Action1<Boolean>() {        @Override        public void call(Boolean aBoolean) {            button.setEnabled( aBoolean );            button.setBackgroundResource( aBoolean ? R.color.button_yes : R.color.button_no );            }        }) ;```

• search, Keyword associative function. Debounce () sends an event without action within a certain amount of time.

   EditText = (editText) Findviewbyid (R.id.edittext); ListView = (ListView) Findviewbyid (R.id.listview); Final arrayadapter<string> adapter = new Arrayadapter<string> (this, Android. R.layout.simple_expandable_list_item_1); Listview.setadapter (adapter); Rxtextview.textchanges (EditText). Debounce (timeunit.milliseconds). Map (New Func1<char                     Sequence, string> () {@Override public String call (Charsequence charsequence) {                     Get the keyword String key = charsequence.tostring ();                 Return key; }}). Observeon (Schedulers.io ()). Map (new func1<string, list<string>> () {@Override public list<string> call (String keyWord) {//get li                    St List<string> dataList = new arraylist<string> (); if (! Textutils.isempty (KeyWord)) {for (String S:getdata ()) {if (s!)                                 = null) {if (S.contains (KeyWord)) {Datalist.add (s);                     }                             }                         }                     }                 return dataList; }}). Observeon (Androidschedulers.mainthread ()). Subscribe (New Action1<list<st                     Ring>> () {@Override public void call (list<string> strings) {                     Adapter.clear ();                     Adapter.addall (strings);                 Adapter.notifydatasetchanged (); }             }) ;

  Run effect
  

Summary :

• RxBindingIt is the 发布--订阅 mode used in the Android control of the click, text changes on. After the rxbinding has converted the tap listener to Observable, it is possible to extend it.

• RxBindingAnd rxlifecycle combined, you can control the life cycle of control monitoring. For rxlifecycle use, refer to Rxjava and Rxandroid III (lifecycle Control and memory optimization)

• This series of code examples are all on GitHub https://github.com/zyj1609wz/RxJava_RxAndroid
