RxJava 和 RxAndroid 四（RxBinding的使用）

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( 600 , TimeUnit.MILLISECONDS ) .map(new Func1<CharSequence, 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 list 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<String>>() { @Override public void call(List<String> strings) { adapter.clear(); adapter.addAll( strings ); adapter.notifyDataSetChanged(); } }) ;
