How can I make BottomSheetDialog match parent height (full screen)

Question

This is the layout that I use:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/layout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top|center_horizontal"
android:background="@color/white"
android:gravity="top|center_horizontal"
android:orientation="vertical">

    <TextView
        android:id="@+id/provisioningTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Phone Number" />

</LinearLayout>

This is my class that creates the Dialog:

open class DialogProvisioningData : BottomSheetDialog {
constructor(context: Context) : super(context)


private lateinit var mBehavior: BottomSheetBehavior<FrameLayout>

override fun setContentView(view: View) {
    super.setContentView(view)
    val bottomSheet = window.decorView.findViewById<View>(R.id.design_bottom_sheet) as FrameLayout
    mBehavior = BottomSheetBehavior.from(bottomSheet)
    mBehavior.peekHeight = Resources.getSystem().getDisplayMetrics().heightPixels
    mBehavior.state = BottomSheetBehavior.STATE_EXPANDED
}

override fun onStart() {
    super.onStart()
    mBehavior.peekHeight = Resources.getSystem().getDisplayMetrics().heightPixels
    mBehavior.state = BottomSheetBehavior.STATE_EXPANDED
}

companion object {
    fun newInstance(context: Context): DialogProvisioningData {
        val dialog = DialogProvisioningData(context)
        var layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater;
        val bottomSheet = layoutInflater.inflate(R.layout.dialog_provisioning, null)
        bottomSheet.layout.setOnClickListener({ dialog.cancel() })
        dialog.setOnShowListener { dialog ->
            val d = dialog as BottomSheetDialog

            val bottomSheet = d.findViewById<View>(R.id.design_bottom_sheet) as FrameLayout?
            BottomSheetBehavior.from(bottomSheet!!).state = BottomSheetBehavior.STATE_EXPANDED
        }
        dialog.setContentView(bottomSheet)
        dialog.show()
        return dialog
    }
}
}

What do I need to change for the BottomSheetDialog to actually be fullscreen? I've set the state to expanded, and peekHeight set to screen height

Answer 1

Don't use fullscreen BottomSheet. you can use from DialogFragment

for showing dialog :

  FragmentManager fragmentManager = getSupportFragmentManager();
    DialogFullscreenFragment newFragment = new DialogFullscreenFragment();
    FragmentTransaction transaction = fragmentManager.beginTransaction();
    transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
    transaction.add(android.R.id.content, newFragment).addToBackStack(null).commit();

DialogFullscreenFragment class:

public class DialogFullscreenFragment extends DialogFragment {


private View root_view;
private Slider slider;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    root_view = inflater.inflate(R.layout.dialog_event, container, false);


    return root_view;
}


@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    return dialog;
}

}

We can solve it by setting our view.minHeight like this :

class SortProductBottomSheet : BaseBottomSheet() {

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View = inflater.inflate(R.layout.dialog_blablabla, container, false)-

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        //THIS IS OUR LIFESAVER
        val dm = Resources.getSystem().displayMetrics
        val rect = dm.run { Rect(0, 0, heightPixels, widthPixels) }
        view.minimumHeight = rect.height()
    }

}
