前言
ToolBar是Android 5.0推出的一个新的导航控件用于取代之前的ActionBar，由于其高度的可定制性、灵活性、具有Material Design风格等优点，越来越多的App也用上了ToolBar。
沉浸式状态栏是从android Kitkat（Android 4.4）开始出现的,它可以被设置成与APP顶部相同的颜色，这就使得切换APP时，整个界面就好似切换到了与APP相同的风格样式一样。
依赖包：
Toolbar, implementation 'androidx.appcompat:appcompat:1.1.0'
沉浸式, implementation 'com.gyf.immersionbar:immersionbar:3.0.0'
1、自定义Toolbar步骤：
1）、定义 /values/styles.xml

2）、自定义toolbar 继承 androidx.appcompat.widget.Toolbar

2、自定义Toolbar使用
1）、res/layout创建布局文件

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="wrap_content"> <com.ktx.view.CustomToolBar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?actionBarSize" android:background="@android:color/white" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" app:titleTextColor="@android:color/black" /></FrameLayout> |
2）、在布局中使用

3）、代码中使用
a、初始化：
|
1
2
3
|
mBinding.root.toolbar.setNavigationIcon(R.mipmap.register_close)mBinding.root.toolbar.setMyCenterTitle(getString(R.string.register), true)mBinding.root.toolbar.setMySettingText(getString(R.string.login)) |
b、点击事件：
|
1
2
3
4
5
6
7
8
|
mBinding.root.toolbar.setNavigationOnClickListener { .... } mBinding.root.toolbar.setSettingTextOnClickListener { ...} |
4）、沉浸式，设置toolbar背景颜色、文字颜色，一般写在基类
|
1

3

10
11
12
|
protected open fun initImmersionBar() { //在BaseActivity里初始化 mImmersionBar = ImmersionBar.with(this) if (toolbar != null) { mImmersionBar.titleBar(toolbar) } mImmersionBar.statusBarDarkFont(true) // mImmersionBar.keyboardEnable(true).navigationBarWithKitkatEnable(false).init() // mImmersionBar.init() ImmersionBar.with(this).init() } |
Google原生的效果，不必多说，可以实现类似这样的效果
注意：
1、配置整个app的toolbar风格，在/value/styles.xml文件修改代码
|
1
2
3
4
5
6
7
8
9
10
|
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <item name="colorPrimary">@android:color/white</item> <item name="colorPrimaryDark">@android:color/white</item> <item name="colorAccent">@android:color/white</item> ... </style> |
2、修改了 toolbar的高度 ，怎么让navigationIcon显示在toolbar中心?
只要设置如下，即可：android:minHeight="@dimen/toolbar_height"
3、toolbar布局文件位置
如果在commonlibrary目录创建该文件，在app 下还需要复制一份，因为在app 使用toolbar，kotlin-android-extensions引用不到commonlibrary目录下的布局文件。
