ImageButton點擊失效

我在如今這個項目開發的過程當中,遇到了ImageButton點擊失效的問題,百思不得其解,甚至開始懷疑人生了,終於發現問題的緣由,先上佈局代碼.

點擊失效的是ID爲share_btn_share的ImageButton,正常看這個頁面沒有任何問題,ImageButton按照正常的setOnClickListener卻沒法響應點擊,注意頂部是一個自定義的TitleView的符合控件,實現Toolbar的做用.內部也有ImageButton,在我重命名這個TitleView的ImageButton的時候,我發現上面佈局裏的ImageButton在Activity裏findViewById的id也被修改了!這說明TitleView內部的ImageButton和佈局裏的ImageButton的Id重複了,致使Android Studio沒法準確找到響應點擊的ImageButton
