我開始瀏覽Neko的教程,我想創建自己的特質。我一直在按照here的描述關注neko的文檔,但是它不斷產生錯誤。在Neko中產生NoSuchMethodException的deftrait
更具體:
; Clojure code
(ns main
(:use [neko.activity :only [defactivity set-content-view!]]
[neko.threading :only [on-ui]]
[neko.ui :only [make-ui config]]
[neko.ui.traits :only [deftrait]]))
(deftrait :on-text-change
{:attributes [:on-text-change]}
[^android.widget.TextView wdg, {:keys [on-text-change]}, opts]
(.addTextChangedListener wdg (reify android.text.TextWatcher
(afterTextChanged [this _])
(beforeTextChanged [this _ _ _ _])
(onTextChanged [this, s, start, before, count]
(on-text-change (.toString s) start before count)))))
(declare ^android.widget.LinearLayout mylayout)
(def main-layout [:linear-layout {:orientation :vertical, :id-holder true}
[:edit-text {:hint "Event name" :id ::name :on-text-change (fn [text _ _ _])}]
[:edit-text {:hint "Event location" :id ::location}]])
(defactivity MainActivity
:def a
:on-create
(fn [this bundle]
(on-ui
(set-content-view! a
(make-ui main-layout)))))
製作錯誤:
java.lang.NoSuchMethodException:找不到在主$ eval1159 $ fn__160.invoke參數主要$ fn__153)方法.SetOnTextChange (NO_SOURCE_FILE:4)
有沒有人遇到過類似的問題,或者知道我做錯了什麼? 在此先感謝您的任何建議。
謝謝你的快速和完美的答案。那就是訣竅。 – Nathan
