Android项目中自定义顶部标题栏
思路及实现步骤
1.定义标题栏布局
2.自定义TitleActivity控制标题栏按钮监听
3.在TitleActivity中实现标题栏以下内容切换- 首先定义标题栏
- <?xml version="1.0" encoding="utf-8"?>
- <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:id="@+id/layout_titlebar"
- android:layout_width="match_parent"
- android:layout_height="52dp"
- android:background="#ed4255" >
- <TextView
- android:id="@+id/text_title"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:ellipsize="marquee"
- android:gravity="center_horizontal|center"
- android:singleLine="true"
- android:text="标题栏"
- android:textColor="#ffffffff"
- android:textSize="20dp" />
- <Button
- android:id="@+id/button_backward"
- android:layout_width="60dp"
- android:layout_height="match_parent"
- android:background="@drawable/title_button_selector"
- android:drawableLeft="@drawable/back_arrow"
- android:drawablePadding="6dp"
- android:ellipsize="end"
- android:gravity="center"
- android:onClick="onClick"
- android:paddingLeft="5dp"
- android:singleLine="true"
- android:text="返回"
- android:textColor="#ffffffff"
- android:textSize="18dp"
- android:visibility="invisible" />
- <Button
- android:id="@+id/button_forward"
- android:layout_width="60dp"
- android:layout_height="match_parent"
- android:layout_alignParentRight="true"
- android:background="@drawable/title_button_selector"
- android:drawablePadding="6dp"
- android:ellipsize="end"
- android:gravity="center"
- android:onClick="onClick"
- android:paddingLeft="5dp"
- android:singleLine="true"
- android:text="提交"
- android:textColor="#ffffffff"
- android:textSize="18dp"
- android:visibility="invisible" />
- </RelativeLayout>
- 定义控制标题栏按钮和标题栏以下内容的布局
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:orientation="vertical" >
- <!-- Title -->
- <include layout="@layout/layout_titlebar" />
- <FrameLayout
- android:id="@+id/layout_content"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:background="#fff" >
- </FrameLayout>
- </LinearLayout>
注:此处使用 <include> 标签引入标题栏,且下方有定义一个空的FrameLayout的布局。

定义TitleActivity控制按钮及布局

MainActivity中调用时直接 extends TitleActivity 使用之前在TitleActivity中定义的方法
