我已經跑了baoyz'庫的樣本,一切都很完美。現在我並沒有把所有的代碼都放在腦海裏。在「簡單活動」類中,找到菜單。 (欲瞭解更多信息,請看這裏的回購:https://github.com/baoyongzhang/SwipeMenuListView) 現在我想爲它設置一個敬酒當我點擊「打開」。默認情況下,當我點擊打開時,沒有任何反應。我想要它做的是顯示一條消息「工作」,以便我可以知道並進行下一步構建。 SimpleActivity.java: package com.baoyz.swipemenulistviewsample;如何將SwipeMenuListView中的Toast添加到「打開」項目中?

我還沒有做任何事情呢,我只是想知道在哪裏實施敬酒行動。 感謝
只能用於調試嗎?爲什麼不使用logcat呢? – shkschneider
