I'll implement typical case of Android, using RxAndroid. (+o+) 7 | 8 | 9 | ## environment 10 | 11 | Will change rapidly... 12 | 13 | - Groovy 2.4.0-beta-3 14 | - rxandroid 0.23.0 15 | - multidex 1.0.0 16 | - swissknife 1.1.4 17 | - greenbot/EventBus 2.4.0 18 | - retrofit 1.8.0 19 | 20 | 21 | ## Form Validation 22 | 23 | 24 | ### require 25 | 26 | emailとpasswordを入力するフォームがある。submitボタンを押した時、それぞれのフォームの空チェックを行い、エラーの場合送信を中止し、エラー表示を行う。 27 | 28 | ![](./art/form_validation.png) 29 | 30 | ### implement 31 | 32 | まずは空チェックをして結果を返すObservableを生成するクラスを作る。 33 | `notEmpty()`はsubscribeされた時に、指定したTextViewが`empty`だとfalse, `!empty`だとtrueを送出するObservable。 success, failureを引数に受け取っているが、これは個別のバリデーション結果に対してアクションを起こしたい場合に指定する。 34 | 35 | ```groovy 36 | @CompileStatic 37 | class FormValidator { 38 | 39 | def static Observable notEmpty(TextView textView, 40 | Action0 success, 41 | Action0 failure) { 42 | return rx.Observable.create({ Subscriber subscriber -> 43 | if (TextUtils.isEmpty(textView.getText())) { 44 | if (failure != null) { 45 | failure.call() 46 | } 47 | subscriber.onNext(false) 48 | } else { 49 | if (success != null) { 50 | success.call() 51 | } 52 | subscriber.onNext(true) 53 | } 54 | subscriber.onCompleted() 55 | } as Observable.OnSubscribe) 56 | } 57 | } 58 | ``` 59 | 60 | `FormValidator`を使ってvalidation対象のEditTextからObservableを作る。それをconcatでつなげる。concatして作ったObservableに`reduce()`と`filter()`をかける。`reduce()`はconcatでつなげたObservableの結果を&して、全てのvalidationが通ったかを表すBooleanを送出する。`filter()`は`reduce()`の結果をそのまま返す。この時falseだったら後続の処理が呼ばれない。 61 | RxAndroidの`ViewObservable.clicks()`を使ってクリックイベントをもらい、その中でをsubscribeする。subscribeする時に渡すAction1が呼び出される時は全てのvalidtionがtrueで通過している状態になる。 62 | 63 | ```groovy 64 | @InjectView(R.id.edit_email) 65 | EditText email; 66 | 67 | @InjectView(R.id.text_email_error) 68 | TextView emailError; 69 | 70 | @InjectView(R.id.edit_password) 71 | EditText password; 72 | 73 | @InjectView(R.id.text_password_error) 74 | TextView passwordError; 75 | 76 | @InjectView(R.id.buttom_submit) 77 | Button submit; 78 | 79 | @Override 80 | protected void onCreate(Bundle savedInstanceState) { 81 | super.onCreate(savedInstanceState); 82 | setContentView(R.layout.activity_form_validation); 83 | 84 | def validators = prepareValidation() 85 | .reduce({ a, b -> a && b }) 86 | .filter({ a -> a }) 87 | 88 | ViewObservable 89 | .clicks(submit) 90 | .subscribe( 91 | { event -> 92 | //クリックイベントがくる度に 93 | //validatorsをsubscribeする 94 | validators.subscribe({ _ -> 95 | submit() 96 | }) 97 | }) 98 | } 99 | 100 | def Observable prepareValidation() { 101 | 102 | //emailをvalidationするObservableを作る 103 | Observable emailEmptyValidator = FormValidator 104 | .notEmpty(email, 105 | hideError(emailError), 106 | showError(emailError, "*Enter your e-mail address.")) 107 | 108 | //passwordをvalidationするObservableを作る 109 | Observable passwordEmptyValidator = FormValidator 110 | .notEmpty(password, 111 | hideError(passwordError), 112 | showError(passwordError, "*Enter your password.")) 113 | 114 | //concatで２つのObservableをつなげて返す 115 | return Observable.concat(emailEmptyValidator, passwordEmptyValidator) 116 | } 117 | ``` 118 | 119 | 補助的なメソッド達。 120 | Support methods. 121 | 122 | 123 | ```groovy 124 | def static Action0 hideError(TextView errorView) { 125 | return { 126 | errorView.setVisibility(View.GONE) 127 | } as Action0 128 | } 129 | 130 | def static Action0 showError(TextView errorView, String message) { 131 | return { 132 | errorView.setText(message) 133 | errorView.setVisibility(View.VISIBLE) 134 | } as Action0 135 | } 136 | ``` 137 | 138 | バリデーションの種類はFormValidatorにメソッドを追加していけばよい。それらをconcatで繋げればいくらでもバリデーションの処理を追加できる。FormValidatorは画面の実装とは独立しているので使いまわせる。 139 | 140 | ## Form validation 2 141 | 142 | ### require 143 | 144 | emailとpasswordを入力するフォームがある。emailとpasswordがinvalidな間、submitをdisabledにする。 145 | validationは以下の通り 146 | 147 | __email__ 148 | 149 | - 空ではない 150 | 151 | __password__ 152 | 153 | - 空ではない 154 | 155 | ### implement 156 | 157 | FormValidatorに`watchNotEmpty()`を追加する。`ViewObservable.text()`を使って指定したTextView(EditText)の内容の変化を監視する。`map`してOnTextChangeEventのTextViewの中身を空チェックするObservableを返却する。 158 | 159 | ```groovy 160 | class FormValidator { 161 | //... 162 | 163 | def static Observable watchNotEmpty(TextView textView, boolean emitInitialValue) { 164 | return ViewObservable.text(textView, emitInitialValue). 165 | map({ OnTextChangeEvent event -> 166 | return !TextUtils.isEmpty(event.text) 167 | }) 168 | } 169 | } 170 | ``` 171 | 172 | `FormValidator.watchNotEmpty()`を使ってバリデーションを実行するObservableを作成する。`Observable.combineLatest()`を使って２つのObservableを合成する。合成した結果を使って`submit`(Button)のenable/disableをセットする。 173 | 174 | ```groovy 175 | @InjectView(R.id.edit_email) 176 | EditText email; 177 | 178 | @InjectView(R.id.edit_password) 179 | EditText password; 180 | 181 | @InjectView(R.id.buttom_submit) 182 | Button submit; 183 | 184 | @Override 185 | protected void onCreate(Bundle savedInstanceState) { 186 | super.onCreate(savedInstanceState); 187 | setContentView(R.layout.activity_form_validation2); 188 | 189 | def emailEmptyObservable = FormValidator.watchNotEmpty(email, true); 190 | def passwordEmptyObservable = FormValidator.watchNotEmpty(password, true); 191 | 192 | Observable.combineLatest(emailEmptyObservable, passwordEmptyObservable, 193 | { a, b -> 194 | return a && b 195 | } as Func2) 196 | .subscribe( 197 | { Boolean isValid -> 198 | submit.setEnabled(isValid) 199 | }) 200 | 201 | ViewObservable 202 | .clicks(submit) 203 | .subscribe( 204 | { _ -> 205 | submit() 206 | }) 207 | } 208 | ``` 209 | 210 | `Observable.concat()`ではなく`Observable.combineLatest()`を使っている。concatは渡したObservableがonComplete()を呼び出さないと次のObservableの結果を送出し始めない。combineLatestは指定したObservableの両方の値がonNext()で出揃ったらFunc2が実行される。 211 | 212 |
