Bottom Drawer

Easy way to make Bottom Sheet with animation

Usage

To customize Bottom Drawer you need to define a new style with extending BottomDialogTheme

You can use the following properties in your BottomDrawer Theme.

Properties Type Default
should_draw_under_status_bar boolean false
should_draw_content_under_handle_view boolean false
bottom_sheet_corner_radius dimension 10dp
bottom_sheet_extra_padding dimension 4dp
bottom_drawer_background color WHITE

It will be something like:

<style name="CustomTheme" parent="BottomDialogTheme">
      <item name="bottom_sheet_extra_padding">4dp</item>
      <item name="should_draw_under_status_bar">true</item>
</style>

You can make your own HandleView and implement TranslationUpdater interface for getting callbacks. Or you can use defined handle views by library like PlainHandleView or PullHandleView (check sample app).

After customizing theme and choosing handle view, you need to override configureBottomDrawer method and pass theme, handle view to BottomDrawerFragment.

So the following example will make Google Tasks fragment like on main preview:

class GoogleTaskExampleDialog : BottomDrawerFragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        super.onCreateView(inflater, container, savedInstanceState)
        return inflater.inflate(R.layout.your_layout, container, false)
    }

    override fun configureBottomDrawer(): BottomDrawerDialog {
        return BottomDrawerDialog.build(context!!) {
            theme = R.style.Plain
            //configure handle view
            handleView = PlainHandleView(context).apply {
                val widthHandle =
                    resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_width)
                val heightHandle =
                    resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_height)
                val params =
                    FrameLayout.LayoutParams(widthHandle, heightHandle, Gravity.CENTER_HORIZONTAL)

                params.topMargin =
                    resources.getDimensionPixelSize(R.dimen.bottom_sheet_handle_top_margin)

                layoutParams = params
            }
        }
    }
}

You also can change color and corner by code in BottomDrawerFragment:

changeCornerRadius(radius: Float)
changeBackgroundColor(color: Int)

Integration

This library is available on jitpack, so you need to add this repository to your root build.gradle:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add the dependency:

dependencies {
    implementation 'com.github.HeyAlex:BottomDrawer:v1.0.0'
}

Samples

You can find more samples in app module, to understand functionality of library.
