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

<com.example.jinboy.codertodeveloperbytcler.java_demo.appdemo.ui.view.TitleView
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"/>

activity

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;
/**
* 左侧返回按钮
*/
public TextView mLeftBackTv;
/**
* 右侧图片
*/
public ImageView mRightButtonIV;
/**
* 右侧文字
*/
public TextView mRightButtonTV;

/**
* 右侧第二个图片按钮
*/
public ImageView mRightTwoIv;
/**

*/

自定义xml控制属性

styleable（这样就可以在xml属性里设置）

<!-- 标题属性 -->

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

<View
android:id="@+id/fake_status_bar"
android:layout_width="match_parent"
android:layout_height="@dimen/statusbar_view_height"
android:background="@android:color/transparent"/>

<TextView
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
