Use ViewPagers in Bottom Sheets and Bottom Sheet Dialogs!

Example

This repository features an example app that demonstrates nested ViewPagers inside a bottom sheet:

Example App

Use for your project

Add the maven repo url to your build.gradle:

repositories {
    maven { url "https://raw.github.com/laenger/maven-releases/master/releases" }
}

Add the library to the dependencies:

dependencies {
    compile "biz.laenger.android:vpbs:0.0.5"
}

Use ViewPagerBottomSheetBehavior for your bottom sheet view:

app:layout_behavior="@string/view_pager_bottom_sheet_behavior"

Setup any nested ViewPager inside the bottom sheet:

BottomSheetUtils.setupViewPager(bottomSheetViewPager)

(This also works when the ViewPager is the bottom sheet view and for further nested ViewPagers)

Use with Bottom Sheet Dialogs

Use ViewPagerBottomSheetDialogFragment as super-class and setup any ViewPager as follows:

public class DialogFragment extends ViewPagerBottomSheetDialogFragment {
    @Override
    public void setupDialog(Dialog dialog, int style) {
        super.setupDialog(dialog, style);
        final View contentView = View.inflate(getContext(), R.layout.dialog_bottom_sheet, null);

        ViewPager viewPager = (ViewPager) contentView.findViewById(R.id.viewpager);
        // ...
        BottomSheetUtils.setupViewPager(viewPager);

        dialog.setContentView(contentView);
    }
}

Example App

How does this work?

ViewPagerBottomSheetBehavior is essentially identical to the original BottomSheetBehavior from the Design Support Library but adds important details: ViewPagers are now properly handled when finding the scrolling child, and this reference can be updated on ViewPager page changes.
