Android自定义ToolBar并实现沉浸式的方法

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

<?xml version="1.0" encoding="utf-8"?>

<resources>

<style name="TextAppearance_TitleBar_Title" parent="TextAppearance.AppCompat.Toolbar.Title">

...

</style>

<style name="TextAppearance_TitleBar_subTitle" parent="TextAppearance.AppCompat.Toolbar.Subtitle">

....

</style>

</resources>

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

public class CustomToolBar extends Toolbar {

private TextView mCenterTitle;

private ImageView mCenterIcon; //中心icon

private TextView mLeftText;

private ImageButton mLeftIcon;

private TextView mSettingText;

//textView in left

public void setCenterTitleWithImgOnClickListener(OnClickListener listener) {

if (mCenterTitle != null) {

((View) mCenterTitle.getParent()).setOnClickListener(listener);

}

}

}

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

<?xml version="1.0" encoding="utf-8"?>

<layout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:binding="http://schemas.android.com/tools">

<data>

<variable

name="viewModel"

type="com.android.playandroid.viewmodel.LoginViewModel" />

</data>

<androidx.constraintlayout.widget.ConstraintLayout

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@color/bkg"

android:orientation="vertical">

<include

layout="@layout/title_layout"

app:layout_constraintLeft_toLeftOf="parent"

app:layout_constraintTop_toTopOf="parent" />

...

</androidx.constraintlayout.widget.ConstraintLayout>

</layout>

3)、代码中使用

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、点击事件:

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

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

<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。
