android自定义标题栏的封装（功能比较完善）

注意：标题栏已经适配沉浸式状态栏

废话不多说直接上代码：

    public interface OnMoveClick {

        void onMoveClick(View img);

    }

    public interface OnDescribeClick {

        void onDescribeClick(View view);

    }

}

以上就是标题栏的全部代码，当然也有自定义属性如下：

   

   

   

   

   

   

       

       

       

       

       

       

   

当然是用起来也是相当简单的：

    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。
