How to set max width for BottomSheetDialogFragment

Question

I'm using the BottomSheetDialogFragment for my modal bottom sheet and would like to set a maximum width so that on tablets/large screens the BottomSheet doesn't occupy the entire width of the screen. How do I approach solving this? Thanks!

Relevant code & resources

fragment_bottomsheet.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    style="@style/BottomSheetStyle">

    <GridLayout
        android:id="@+id/bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:alignmentMode="alignBounds"
        android:columnOrderPreserved="false"
        android:columnCount="3"
        android:paddingTop="16dp"
        android:paddingBottom="8dp"
        android:paddingRight="8dp"
        android:paddingLeft="8dp"
        app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/image1"
            android:text="Open"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/image2"
            android:text="Save"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/image3"
            android:text="Send"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/image4"
            android:text="Upload"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/image5"
            android:text="Share"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:drawableTop="@drawable/iamge6"
            android:text="More"/>

    </GridLayout>

</android.support.design.widget.CoordinatorLayout>

res/values/styles.xml:

<style name="BottomSheetStyle">
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_gravity">center_horizontal</item>
</style>

res/values-w600dp/styles.xml:

<style name="BottomSheetStyle">
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_width">640dp</item>
    <item name="android:layout_gravity">center_horizontal</item>
</style>

This works for me on BottomSheetDialogFragment. I was able to set the max width with this:

dialog.maxWidth = Resources.getSystem().displayMetrics.widthPixels

You can set this in the onCreateDialog function. This example sets the width of the bottom sheet to the width of the display.

Hope this helps!

If you want to do it purely in xml, you can set a style and use android:maxWidth

For example:

<LinearLayout
   android:id="@+id/bottom_sheet"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:orientation="vertical"
   android:background="@color/white"
   app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
   style="@style/styleWithFixedWidth"
 >

and in styles.xml

<style name="styleWithFixedWidth">
  <item name="android:maxWidth">550dp</item>
</style>

A variation of the OP's answer that takes into consideration device's pixel density and orientation:

public final class MyBottomSheetDialogFragment extends BottomSheetDialogFragment {
    ...

    private static int dpToPx(int dp) {
        // https://developer.android.com/guide/practices/screens_support.html#dips-pels
        float density = Resources.getSystem().getDisplayMetrics().density;
        return (int) ((dp * density) + 0.5f);
    }

    @Override
    public void onResume() {
        super.onResume();

        Configuration configuration = getActivity().getResources().getConfiguration();
        if (configuration.orientation == Configuration.ORIENTATION_LANDSCAPE &&
                configuration.screenWidthDp > 450) {
            // you can go more fancy and vary the bottom sheet width depending on the screen width
            // see recommendations on https://material.io/components/sheets-bottom#specs
            getDialog().getWindow().setLayout(ViewUtils.dpToPx(450), -1);
        }
    }
}

As you mention, BottomSheetDialogFragment does not seem to respect "wrap_content" (it always matches parent on width, even if all the views it contains have a width of "wrap_content"). I found that the best workaround for me was to utilize OnGlobalLayoutListener to listen for the appropriate time to adjust the width. Example:

 @Override
public void setupDialog(final Dialog dialog, int style) {
    super.setupDialog(dialog, style);
    View v = View.inflate(getActivity(), R.layout.my_bottom_sheet, null);
    View viewWithGreatestWidth = v.findViewById(R.id.my_super_wide_view);
    // Your view setup code goes here ....

    if(getResources().getBoolean(R.bool.isTablet)) {
        v.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                    v.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                } else {
                    v.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                }

                // Can also just use your own preset "max width" value here;
                // This code just lets you fake "wrap_content" value
                getDialog().getWindow().setLayout(viewWithGreatestWidth.getMeasuredWidth(), WindowManager.LayoutParams.WRAP_CONTENT);
            }
        });
    }

    dialog.setContentView(v);
}

I found a solution which works for me:

@Override
public void onResume() {
    super.onResume();

    // Resize bottom sheet dialog so it doesn't span the entire width past a particular measurement
    WindowManager wm = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();
    DisplayMetrics metrics = new DisplayMetrics();
    display.getMetrics(metrics);
    int width = metrics.widthPixels < 1280 ? metrics.widthPixels : 1280;
    int height = -1; // MATCH_PARENT
    getDialog().getWindow().setLayout(width, height);
}

Essentially this allows me to dynamically specify dimensions for my BottomSheet based on display.
