一、toolbar的使用
1、xml添加toolbar
使用默认高度：android:layout_height=“?attr/actionBarSize”
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/Theme.Toolbar.AppBarOverlay"
app:layout_constraintTop_toTopOf="parent">
<androidx.appcompat.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/Theme.Toolbar.PopupOverlay" />
</com.google.android.material.appbar.AppBarLayout>2、主题
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="Theme.Test" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">@color/purple_500</item>
<item name="colorPrimaryVariant">@color/purple_700</item>
<item name="colorOnPrimary">@color/white</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>
<item name="colorOnSecondary">@color/black</item>
<!-- Status bar color. -->
<item name="android:statusBarColor">?attr/colorPrimaryVariant</item>
<!-- Customize your theme here. -->
</style>
<!-- 关键代码 上面Theme.Test是原本的主题 -->
<style name="Theme.Test.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="Theme.Toolbar.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="Theme.Toolbar.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>3、activity代码
supportActionBar?.setDisplayHomeAsUpEnabled(true)//显示箭头
附加：绑定
buildFeatures {
viewBinding true
}
二、右上角setting
1、activity里面添加
override fun onCreateOptionsMenu(menu: Menu): Boolean {
// Inflate the menu; this adds items to the action bar if it is present.
menuInflater.inflate(R.menu.menu_main, menu)
return true
}2、menu文件夹
menu_main.xml代码：
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.oneway.demo.toolbar.MainActivity">
<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="设置"
app:showAsAction="never" />
<item
android:id="@+id/action_exit"
android:orderInCategory="100"
android:title="退出"
app:showAsAction="never" />
</menu>一 二 的代码地址为：
三、FloatingActionButton悬浮按钮
用CoordinatorLayout展示效果最好
在xml里添加：
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_marginEnd="16dp"
android:layout_marginBottom="16dp"
app:srcCompat="@android:drawable/ic_dialog_email"
/>点击事件
binding.fab.setOnClickListener { view ->
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show()
}四、插件状态栏的使用
1、状态栏工具类（BarUtils、Utils）的使用
效果图：
调用代码：
在onCreate代码里，super.onCreate(savedInstanceState)的前面调用
BarUtils.setStatusBarColor(this, Color.TRANSPARENT)
BarUtils.setStatusBarLightMode(this, true)BarUtils：

}2、插件状态栏的使用
状态栏的变色等操作，推荐使用依赖包：
// 基础依赖包，必须要依赖
implementation 'com.gyf.immersionbar:immersionbar:3.0.0'
// fragment快速实现（可选）
implementation 'com.gyf.immersionbar:immersionbar-components:3.0.0'
// kotlin扩展（可选）
implementation 'com.gyf.immersionbar:immersionbar-ktx:3.0.0'详细介绍可以看：
https://github.com/gyf-dev/ImmersionBar
1、设置状态栏的背景颜色
kotlin用法：
immersionBar {
statusBarColor(R.color.colorPrimary)
}2、设置状态栏的字体颜色（亮色和深色）
kotlin用法：
immersionBar {
statusBarDarkFont(true) //状态栏字体是深色，不写默认为亮色
}五、封装自定义的toolbar（推荐）
非常推荐使用：封装的Title标题栏 ，比Toolbar更好用，当然没有Toolbar那么强大，不过通常的功能均能更好的满足，不满足的再用Toolbar就行了
TitleBar的返回键：返回事件已经做统一处理
class TitleLayout(context: Context, attrs: AttributeSet) : ConstraintLayout(context, attrs) {
private var mBinding: LayoutTitleBinding
init {
// 自定义TitleLayout的相关属性
val typedArray = context.obtainStyledAttributes(attrs, R.styleable.TitleLayout)
val titleBackgroundColor = typedArray.getColor(
R.styleable.TitleLayout_titleBackgroundColor,
ContextCompat.getColor(context, R.color.purple_500)
)
val backIconRes =
typedArray.getResourceId(R.styleable.TitleLayout_backIconRes, R.drawable.ic_back)
val isShowBack = typedArray.getBoolean(R.styleable.TitleLayout_isShowBack, true)
val titleTextColor = typedArray.getColor(
R.styleable.TitleLayout_titleTextColor,
ContextCompat.getColor(context, R.color._ffffff)
)
val titleTextSize = typedArray.getDimensionPixelSize(
R.styleable.TitleLayout_titleTextSize,
ScreenUtil.sp2px(context, 20f)
)
val titleText = typedArray.getString(R.styleable.TitleLayout_titleText)
typedArray.recycle()
// 自定义TitleLayout的布局
mBinding = DataBindingUtil.inflate(
LayoutInflater.from(context),
R.layout.layout_title,
this,
true
)
// 设置TitleLayout的背景色
mBinding.clTitleBar.setBackgroundColor(titleBackgroundColor)
// TitleBar的返回键
mBinding.ivBack.apply {
visibility = if (isShowBack) View.VISIBLE else View.GONE
setImageResource(backIconRes)
setOnClickListener { (context as Activity).onBackPressed() }
}
// TitleBar的标题文本
mBinding.tvTitleText.apply {
setTextColor(titleTextColor)
setTextSize(TypedValue.COMPLEX_UNIT_PX, titleTextSize.toFloat())
text = titleText
