ListView實現點擊事件以及總結

差點嚇死我了，好不容易寫的博客沒有了，還好有自動保存功能，不然我真的是嗚嗚。。。

---恢復內容開始---

 

開學一個月了，終於可以看見自己的作品雛形了。

從一個小白到現在半年了，覺得日子過得比較充實，回頭看看滿是值得紀念的。大一的時候覺得大學就是一個讓人會變的頹廢的地方，除了睡覺恐怕都是在扣手機。很幸運的是我，在辦公室值班得到了加入工作室一起學習的機會。雖然剛開始入門的時候就像是一只無頭蒼蠅一樣亂撞。沒有任何的方向，雖然看似是在學習，但是卻沒有做出來任何的東西。一個學期過去了，除了會做一些簡單的頁面之外，連一個登錄的功能都沒有實現。曾經想過要放棄，覺得自己可能不是一個編程的料。但是一想到機會失去了就恐怕再也找不到這樣的優越的條件了。暑假就又重新把Android的基礎視頻又看了一遍，重新穩固了老師說的知識點，發現了以前沒有注意到的細節。雖然看視頻可能是一件浪費時間的學習途徑。但是我覺得這個途徑還是很有效的，因為除了可以獲得課本知識以外還可以聽一些課本上沒有講到過得東西。暑假的時候一次偶然的機會，在寫博客的時候，收到了一個消息。讓加入一個IT交流群，抱着試試的態度可以認識到幾個大神的心態加入了其中，也許真的是太幸運了。真的讓我遇到了這樣的幾個人。雖然不是Android開發，但是在他們的幫助下，覺得IT的大門一點點向我打開了。一個暑假讓我覺得自己成長了，以前是一遇到問題就去找別人解決，現在終於可以自己學會試着解決一些問題了。我把這個群分享給大家，期待可以有更多的人從中受益。

順便分享一點我在群里面的心得，如果你是一個女生就換一個比較女生化點的頭像，這樣的話你會發現會有很多人主動跟你解決問題的。這群里面的群主是特別厲害的任務之一，基本上我遇到問題在他的指點就會迎刃而解的。現在的我已經打算加入到這個神奇的行業當中了。

2016年還有兩個月就要結束了，我想我的那個目標可以快實現了。我要加油!

不說了，開始粘代碼嘍：布局文件我就不粘了，實在是太多了。我相信你們一定看着界面會做出來的。

這個類我就不粘代碼了，設計一些信息，就截圖了，相信你能看的懂。
