A new way to improve navigation in your app
Its really easy integrate to your project
Important: library was migrated from JCenter to MavenCentral
It means that it may be necessary to add mavenCentral repository to your repositories list
allprojects {
repositories {
// your repositories
mavenCentral()
}
}- Maven
<dependency>
<groupId>com.github.st235</groupId>
<artifactId>expandablebottombar</artifactId>
<version>X.X</version>
<type>pom</type>
</dependency>
- Gradle
implementation 'com.github.st235:expandablebottombar:X.X'
- Ivy
<dependency org='com.github.st235' name='expandablebottombar' rev='X.X'>
<artifact name='expandablebottombar' ext='pom' ></artifact>
</dependency>
P.S.: Check out latest version code in badge at the top of this page.
Really simple as I wrote earlier
Firstly, you should declare your view in xml file
<github.com.st235.lib_expandablebottombar.ExpandableBottomBar
android:id="@+id/expandable_bottom_bar"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="20dp"
app:exb_backgroundCornerRadius="25dp"
app:exb_backgroundColor="#2e2e2e"
app:exb_itemInactiveColor="#fff"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />Then you should add menu items to your navigation menu
To access menu call bottomBar.menu on your navigation view
val bottomBar: ExpandableBottomBar = findViewById(R.id.expandable_bottom_bar)
val menu = bottomBar.menu
menu.add(
MenuItemDescriptor.Builder(
this,
R.id.icon_home,
R.drawable.ic_home,
R.string.text,
Color.GRAY
)
.build()
)
bottomBar.onItemSelectedListener = { view, menuItem ->
/**
* handle menu item clicks here,
* but clicks on already selected item will not affect this callback
*/
}
bottomBar.onItemReselectedListener = { view, menuItem ->
/**
* handle here all the click in already selected items
*/
}If your menu is constantly, you may specify it from xml
Firstly, you should declare menu items in xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/home"
android:title="@string/text"
android:icon="@drawable/ic_home"
app:exb_color="#FF8888" />
<item
android:id="@+id/settings"
android:title="@string/text4"
android:icon="@drawable/ic_settings"
app:exb_color="@color/colorSettings" />
<item
android:id="@+id/bookmarks"
android:title="@string/text3"
android:icon="@drawable/ic_bookmarks"
app:exb_color="#fa2" />
</menu>each item tag has following attributes:
| property | type | description |
|---|---|---|
| id | reference | an id of menu item |
| exb_color | reference/color | color of element, it may be color reference or color |
| icon | reference | icon reference (vector drawables supported) |
| title | reference/text | item title |
| exb_badgeColor | color | notification badge background color. It will override the color from layout attribute |
| exb_badgeTextColor | color | notification badge text color. It will override the color from layout attribute |
Just like any Android menu 😉
Then you should reference this xml file at the view attributes
<github.com.st235.lib_expandablebottombar.ExpandableBottomBar
android:id="@+id/expandable_bottom_bar"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="20dp"
app:exb_backgroundCornerRadius="25dp"
app:exb_itemInactiveColor="#fff"
app:exb_items="@menu/bottom_bar"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent" />| property | type | description |
|---|---|---|
| exb_elevation | dimen | component elevation (important: api 21+) |
| exb_backgroundColor | color | bottom bar background color |
| exb_transitionDuration | integer | time between one item collapsed and another item expanded |
| exb_backgroundCornerRadius | dimen | bottom bar background corners radius |
| exb_itemInactiveColor | color | item menu color, when its inactive |
| exb_itemBackgroundCornerRadius | dimen | item background corner radius |
| exb_itemStyle | enum: normal, outline, stroke | controls the style of items. normal = items are filled with solid color; outline = no fill, only border; stroke = fill + border |
| exb_itemBackgroundOpacity | float | item background opacity (important: final color alpha calculates by next formulae alpha = opacity * 255) |
| exb_item_vertical_margin | dimen | top & bottom item margins |
| exb_item_horizontal_margin | dimen | left & right item margins |
| exb_item_vertical_padding | dimen | top & bottom item padding |
| exb_item_horizontal_padding | dimen | left & right item padding |
| exb_items | reference | xml supported menu format |
| exb_notificationBadgeBackgroundColor | color | notification badge background color. Will be applied to all menu items |
| exb_notificationBadgeTextColor | color | notification badge text color. Will be applied to all menu items |
/**
* Returns notification object
*/
val menu = bottomBar.menu
val notification = menu.findItemById(i.itemId).notification() // itemId is R.id.action_id
notification.show() // shows simple dot-notification
notification.show("string literal") // shows notification with counter. Counter could not exceed the 4 symbols length
notification.clear() // removes notification badge from menu itemUsually Drawer or BottomNavigationView attached to navigation controller with NavigationUI.setupWithNavController(view, navController), but this system is not applicable
to customview components. That's why ExpandableBottomBar offers it's own ExpandableBottomBarNavigationUI
To attach ExpandableBottomBar to your navigation components you should use the same approach
ExpandableBottomBarNavigationUI.setupWithNavController(bottomNavigation, navigationController)Do you waiting for Coordinator Layout support - and it is already here! Fabs and Snackbars aligned by bottom bar! Hooray 🎉
Available without registration and SMS, starting from 0.8 version. Seriously, everything is already working out of the box - nothing needs to be done.
But... if you need to support hiding the menu by list/grid scroll - then you are really lucky!
This functionality is very simple to implement. You need to redeclare custom Coordinator Layout Behavoir to ExpandableBottomBarScrollableBehavior.
<github.com.st235.lib_expandablebottombar.ExpandableBottomBar
android:id="@+id/expandable_bottom_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:layout_behavior="github.com.st235.lib_expandablebottombar.behavior.ExpandableBottomBarScrollableBehavior"
app:items="@menu/bottom_bar" />Really easy ;D
After integration this behavior should looks like:
