一個按鈕鏈接到一個ImageView與縮放

Question

我想做一個鏈接按鈕到一個ImageView，它的工作，但沒有縮放，在此之前，它只用於通過您的手機運行它時使用縮放當它沒有鏈接按鈕時，我有代碼，這是錯誤的！ eclipse中有沒有人有https://play.google.com/store/apps/details?id=uk.co.senab.photoview.sample？

我覺得你是在使用Here的代碼。爲什麼不使用代碼來更改佈局，而不是使用sites.java中的所有瘋狂內容。它有官方文件here。請仔細閱讀本文檔中的所有內容，如果問題仍然存在，請告訴我，以便我編輯此代碼以更改動畫布局。
