Android UI 之自定义标题栏 + 沉浸式状态栏
本文出自：http://blog.csdn.net/dt235201314/article/details/77161904
一丶效果图
二丶技术点
1.标题栏UI统一，自定义
2.沉浸式标题栏，StatusBarUtil开源工具类
开源地址：https://github.com/laobie/StatusBarUtil
详解文章：https://juejin.im/post/5989ded56fb9a03c3b6c8bde
3.适配问题
三丶主要解决问题
1.标题栏状态栏同色
2.我的页面图片全屏展现
四丶自定义后的使用代码
AndroidManifest
android:theme="@style/AppTheme.NoActionBar">
.xml
android:id="@+id/title_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:title_left_text=""
app:title_left_text_drawable_left="@mipmap/blue_back_icon"
app:title_name="Android基础"/> title_view = (TitleView) findViewById(R.id.title_view); title_view.setContainerBackgroundColor(this,R.color.gray2,0xffefefef); title_view.setLeftToBack(this);这样就OK啦
五丶核心代码
1.自定义TiTleView（返回键，返回提醒文字，标题，右边图片，右边文字）
/** * 标题栏View */ public class TitleView extends RelativeLayout { /** * 容器 */ private View mContainer; /** * 居中标题 -- 当显示居中标题时不显示左侧标题 */ public TextView mTitleCenterTV; /** * 左侧返回按钮 */ public ImageView mLeftButtonIV;

自定义xml控制属性
styleable（这样就可以在xml属性里设置）
name="TitleAttr"> name="title_name" format="reference|string" /> name="title_color" format="color" /> name="title_left_text" format="reference|string" /> name="title_left_text_color" format="color" /> name="title_left_image" format="reference" /> name="title_right_visiable" format="boolean" /> name="title_name_gravity"> name="left" value="3" /> name="center" value="17" /> name="right" value="5" /> name="title_left_back" format="boolean" /> name="title_right_image" format="reference" /> name="title_right_text" format="reference|string" /> name="title_right_text_color" format="color" /> name="title_right_image_two" format="reference" /> name="title_right_text_two" format="reference|string" /> name="title_height" format="dimension" /> name="title_right_text_drawable_right" format="reference" /> name="title_right_text_drawable_left" format="reference" /> name="title_right_text_two_drawable_right" format="reference" /> name="title_right_text_two_drawable_left" format="reference" /> name="title_left_text_drawable_right" format="reference" /> name="title_left_text_drawable_left" format="reference" />
2.StatusBarUtil
这个直接开源库里拿来用（注意要copy部分资源文件）

StatusBarUtil.setTranslucentForImageView(HomeActivity.this, 0, null);注意点，适配问题
Title上填充一个View，防止标题栏置顶
当版本为v19，填充状态栏高度25dp
当版本为v21以上状态栏填充0
android:id="@+id/fake_status_bar"
android:layout_width="match_parent"
android:layout_height="@dimen/statusbar_view_height"
android:background="@android:color/transparent"/>
android:id="@+id/title_bar"
android:layout_width="match_parent"
android:layout_below="@+id/fake_status_bar"
android:layout_height="@dimen/title_bar_height"
android:textColor="@color/black33"
android:text="我的"
android:textSize="18sp"
android:gravity="center"
android:background="@android:color/transparent"/> 标题栏，状态栏同色
写在TitleView的方法
/** * 设置标题栏颜色,状态栏颜色 * @param color1 * @param color2 */ public void setContainerBackgroundColor(Activity activity,int color1,int color2) { mContainer.findViewById(R.id.title_bar).setBackgroundColor(getResources().getColor(color1)); StatusBarUtil.setColor(activity,color2,0); }注意点，第二个颜色值要设置透明
title_view.setContainerBackgroundColor(this,R.color.gray2,0xffefefef);六丶总结
1.状态栏设置相关知识，StatusBarUtil使用
2.自定义xml设置属性学习
3.有关v19,v21资源文件适配
