前言
ToolBar是Android 5.0推出的一個新的導(dǎo)航控件用于取代之前的ActionBar，由于其高度的可定制性、靈活性、具有Material Design風(fēng)格等優(yōu)點，越來越多的App也用上了ToolBar。
沉浸式狀態(tài)欄是從android Kitkat（Android 4.4）開始出現(xiàn)的,它可以被設(shè)置成與APP頂部相同的顏色，這就使得切換APP時，整個界面就好似切換到了與APP相同的風(fēng)格樣式一樣。
依賴包：
Toolbar, implementation 'androidx.appcompat:appcompat:1.1.0'
沉浸式, implementation 'com.gyf.immersionbar:immersionbar:3.0.0'
1、自定義Toolbar步驟：
1）、定義 /values/styles.xml
<?xml version="1.0" encoding="utf-8"?>
2）、自定義toolbar 繼承 androidx.appcompat.widget.Toolbar

}2、自定義Toolbar使用
1）、res/layout創(chuàng)建布局文件
2）、在布局中使用
...
3）、代碼中使用
a、初始化：
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、點擊事件：
mBinding.root.toolbar.setNavigationOnClickListener {
....
}
mBinding.root.toolbar.setSettingTextOnClickListener {
...
}4）、沉浸式，設(shè)置toolbar背景顏色、文字顏色，一般寫在基類
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，不必多說，可以實現(xiàn)類似這樣的效果
注意：
1、配置整個app的toolbar風(fēng)格，在/value/styles.xml文件修改代碼
2、修改了 toolbar的高度 ，怎么讓navigationIcon顯示在toolbar中心
只要設(shè)置如下，即可：android:minHeight="@dimen/toolbar_height"
3、toolbar布局文件位置
如果在commonlibrary目錄創(chuàng)建該文件，在app 下還需要復(fù)制一份，因為在app 使用toolbar，kotlin-android-extensions引用不到commonlibrary目錄下的布局文件。
看完這篇關(guān)于Android如何自定義ToolBar和實現(xiàn)沉浸式的文章，如果覺得文章內(nèi)容寫得不錯的話，可以把它分享出去給更多人看到。
