}

以上就是标题栏的全部代码，当然也有自定义属性如下：

<declare-styleable name="TitleBarView">

<attr name="is_immersion" format="boolean" />

<attr name="title" format="string" />

<attr name="describe" format="string" />

<attr name="img_move_src" format="reference" />

<attr name="img_finish_src" format="reference" />

<attr name="titlebar_style" format="integer">

<enum name="finish_title" value="0" />

<enum name="finish_title_text" value="1" />

<enum name="finish_title_move" value="2" />

<enum name="finish_title_text_move" value="3" />

<enum name="finish_title_move_text" value="4" />

<enum name="title" value="5" />

</attr>

</declare-styleable>

当然是用起来也是相当简单的：

<driver.daijia.com.driver.view.TitleBarView

android:layout_width="match_parent"

android:layout_height="?attr/actionBarSize"

app:img_finish_src="@mipmap/img_finish_white"

app:img_move_src="@mipmap/img_finish_white"

app:title="注册"

app:titlebar_style="finish_title_move_text" />

还有很多功能不一一演示了。

分享出来，希望能帮助很多同事，减少一部分工期时间，如果有漏洞或是性能问题，请与我联系，谢谢。
