Android項目中自訂頂部標題列

下面給大家詳細介紹android中自訂頂部標題列的思路及實現方式

 

先來圖：

 

思路及實現步驟

 

1.定義標題列布局

2.自訂TitleActivity控制標題列按鈕監聽

3.在TitleActivity中實現標題列以下內容切換

 

首先定義標題列

 

 

 

 

定義控制標題列按鈕和標題列以下內容的布局

 

 

            <framelayout android:background="#fff" android:id="@+id/layout_content" android:layout_height="match_parent" android:layout_width="match_parent">    </framelayout>

註：此處使用 標籤引入標題列，且下方有定義一個空的FrameLayout的布局。

 

 

 

定義TitleActivity控制按鈕及布局

MainActivity中調用時直接 extends TitleActivity 使用之前在TitleActivity中定義的方法
