Anko Navigation Drawer

Easy implementation Navigation Drawer in Anko Layout support New Material Design, multi styles, custom icon/drawable navigation and custom font.

DEFAULT STYLE	NEW MATERIAL STYLE	GOOGLE KEEP STYLE

SETUP

1. Add gradle dependency

implementation 'com.utsman.kucingapes:ankodrawer:0.2.4'

//required anko libraries
implementation "org.jetbrains.anko:anko:$anko_version"
implementation "org.jetbrains.anko:anko-design:$anko_version"

2. Add drawer in onCreate

Implement AnDrawerClickListener on your activity class. Add after super.onCreate(savedInstanceState)

val drawer = AnDrawer(clickListener, colorDrawer)
frameLayout { anDrawerLayoutWithToolbar(drawer) }

Example

class MainActivity : AppCompatActivity(), AnDrawerClickListener {
    override fun onCreate(savedInstanceState: Bundle) {
        super.onCreate(savedInstanceState)
        
        // code your drawer
        val drawer = AnDrawer(this, R.color.colorPrimary)
        frameLayout { anDrawerLayoutWithToolbar(drawer) }
    }
}

3. Add MainUI class

• Don't apply MainUI with MainUI().setContentView(this)
• Extend MainUI with AnkoComponent<ViewGroup>

Example

class MainUi : AnkoComponent<ViewGroup> {
    override fun createView(ui: AnkoContext<ViewGroup>): View = with(ui) {
        coordinatorLayout {
            relativeLayout {
                textView("MAIN VIEW").lparams { centerInParent() }
            }.lparams(matchParent, matchParent)
        }
    }
}

Add after frameLayout { anDrawerLayoutWithToolbar(drawer) }

AnDrawerInit.setupMainView(this, MainUi())

Items Navigation

Simple

val item = AnDrawerItem("Title item")
drawer.addItems().add(item)

Divider

val divider = AnDrawerItem(AnDrawerItem.DIVIDER)
drawer.addItems().add(divider)

Optional

- Add icon (very recommended)

val item = AnDrawerItem("Title item").addIcon(R.drawable.ic_face)

- Add identifier (very recommended)

val item = AnDrawerItem("Title item").addIdentifier(1)

- Disable focus
When item disable focus, item can't be highlight on click, suitable with intent

val item = AnDrawerItem("Title item").setFocusable(false)

- Selected item
Select item on first launch app, need identifier on item

drawer.setSelectedItem(identifier)

Example

drawer.addItems().apply {
    val item1 = AnDrawerItem("Item 1")
        .addIcon(R.drawable.ic_emoticon)
        .addIdentifier(1)

    val item2 = AnDrawerItem("Item 2")
        .addIcon(R.drawable.ic_face)
        .addIdentifier(2)
        
    val divider = AnDrawerItem(AnDrawerItem.DIVIDER)
    
    add(divider)
    add(item1)
    add(item2)
    drawer.setSelectedItem(2)
}

Item Clicked

Override function onDrawerClick from AnDrawerClickListener and setup click listener with identifier item

override fun onDrawerClick(identifier: Int) {
    super.onDrawerClick(identifier)
    when (identifier) {
        1 -> toast("wah")
        2 -> toast("gile")
        3 -> toast("lu")
    }
}

Custom Toolbar (very recommended)

1. Change style parent to Theme.AppCompat.Light.NoActionBar in styles.xml

2. Add toolbar or themedToolbar from org.jetbrains.anko.appcompat.v7 in your MainUI class

class MainUi : AnkoComponent<ViewGroup> {
    override fun createView(ui: AnkoContext<ViewGroup>): View = with(ui) {
        coordinatorLayout {
        
            // toolbar
            themedToolbar(R.style.ThemeOverlay_AppCompat_Dark) {
                backgroundColorResource = R.color.colorPrimary
                id = R.id.toolbar
                title = context.getString(R.string.app_name)
            }.lparams(matchParent, dimenAttr(R.attr.actionBarSize))
            // end toolbar
            
            relativeLayout {
                textView("MAIN VIEW").lparams { centerInParent() }
            }.lparams(matchParent, matchParent)
        }
    }
}

And add customToolbar(activity, toolbar) after setupMainView

AnDrawerInit.setupMainView(this, MainUi())

// setup toolbar
AnDrawerInit.customToolbar(this, find(R.id.toolbar))

Without custom toolbar	with custom toolbar

Icon Navigation Toolbar

You can add custom toolbar with customToolbar(activity, toolbar, int_icon) or customToolbar(activity, toolbar, drawable)

• Add your own custom toolbar after setupMainView

AnDrawerInit.setupMainView(this, MainUi())
// your toolbar with custom icon
AnDrawerInit.customToolbar(this, find(R.id.toolbar), icon)

SPEC ICON
width = 24dp
height = 24dp

or for drawable
width = 30dp
height = 30dp

You can find material icon in https://material.io/tools/icons/, convert svg to xml in http://inloop.github.io/svg2android/

ICON DRAWABLE
I recommend use Picasso and Picasso Transformations for load and make it circle

In gradle

implementation 'com.squareup.picasso:picasso:2.71828'
implementation 'jp.wasabeef:picasso-transformations:2.2.1'

Add customToolbar in Target Picasso after setupMainView

AnDrawerInit.setupMainView(this, MainUi())
// get drawable and circle it using picasso
Picasso.get()
    .load(R.drawable.cat)
    .transform(CropCircleTransformation()) // transform to circle
    .into(object : Target {
        override fun onPrepareLoad(placeHolderDrawable: Drawable) {}

        override fun onBitmapFailed(e: Exception, errorDrawable: Drawable) {}

        override fun onBitmapLoaded(bitmap: Bitmap, from: Picasso.LoadedFrom) {
             
            // add drawable from bitmap
            val drawable = BitmapDrawable(resources, Bitmap.createScaledBitmap(bitmap, dip(30), dip(30), true))
            
            // add custom toolbar
            AnDrawerInit.customToolbar(this@MainActivity, find(R.id.toolbar), drawable)
            
        }

    })

With default icon	With custom icon	With drawable icon

Header Navigation (optional)

You need anko class header with extend AnkoComponent<ViewGroup>, and setup with

AnDrawerInit.setupHeader(this, HeaderUi())

Example HeaderUI

class HeaderUi : AnkoComponent<ViewGroup> {
    override fun createView(ui: AnkoContext<ViewGroup>): View = with(ui) {
        relativeLayout {
            lparams(matchParent, dip(200))
            backgroundColorResource = R.color.colorPrimary
            textView("CUSTOM HEADER") {
                textColorResource = android.R.color.white
                typeface = Typeface.DEFAULT_BOLD
                textSize = 20f
            }.lparams { centerInParent() }
        }
    }
}

Styles (optional)

Available style:

1. AnDrawerView.STYLE.DEFAULT
2. AnDrawerView.STYLE.NEW_MATERIAL
3. AnDrawerView.STYLE.GOOGLE_KEEP

Setup style

drawer.setNavigationStyle(AnDrawerView.STYLE.GOOGLE_KEEP)

Open and Close Drawer

AnDrawerInit.openDrawer(activity) // open drawer
AnDrawerInit.closeDrawer(activity) // close drawer 

Drawer StatusBar Color

drawer.setDrawerStatusBar(int_color)

Drawer Custom Font

drawer.setFont("fonts/GoogleSans-Medium.ttf") // font from assets

Example

Example class MainActivity.kt
