當按下按鈕時更改XML佈局

Question

我試圖在按下按鈕時更改滾動視圖內部的線性佈局的xml佈局/內容。當按下按鈕或使用setVisibility時，我不想調用新的Activity。

到目前爲止，屏幕的10％被預留爲一個導航欄外殼2個按鈕。下面是一個內部呈線性佈局的滾動視圖，其內部將是內容。當按下「下一個」按鈕時，我希望在線性佈局內更改內容。 這是一個參考應用程序，旨在保存50頁以上的信息。

Answer 1

您可以使用FragmentPager

Answer 2

你不說爲什麼你不希望使用setVisivility()，但我的第一個建議是使用基於可見或不可見一個FrameLayout並設置不同的看法按鈕按下。另一個想法是使用ViewFlipper。
