Custom FragmentDialog with round corners and not 100% screen width

Question

I am creating a custom fragment dialog with round corners and with layout that would not fill the screen width (I would prefer if it just wrapped its content).

this is my rounded_dialog.xml in drawable folder, which is called by my Custom ThemeWithCorners as a background for the dialog. I also tried to set it as background to the linear layout which creates its content but nothing works.

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" 
>
<solid android:color="@android:color/white"/>
<corners android:radius="20dp"
/>
</shape>

and this is how i call the dialog:

final String FTAG = "TAG_FRAGMENT_DIALOG_CALENDAR";
    dialog = (CalendarDialog) fm.findFragmentByTag(FTAG);
    ft = fm.beginTransaction();
    if (dialog != null)
    {
        ft.remove(dialog);
    }
    dialog = CalendarDialog.newInstance(this);      
    dialog.setCancelable(true);

    ft.add(dialog, FTAG);
    ft.show(dialog);
    ft.commit();

In onCreate method of the dialog I set the style and theme:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NO_TITLE, R.style.ThemeWithCorners);      
}

This is the onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
getDialog().setCanceledOnTouchOutside(true);
v = (MyCalendar)inflater.inflate(R.layout.calendar_dialog, container, true)
    return v;
}

I also tried to add this to onCreateDialog method as other answers on SO suggested but did not work either:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    Dialog d =  super.onCreateDialog(savedInstanceState);
    LayoutParams lp=d.getWindow().getAttributes();
    d.getWindow().setBackgroundDrawable(new ColorDrawable(0));
    lp.width=-2;lp.height=-2;lp.gravity=Gravity.CENTER;
    lp.dimAmount=0;            
    lp.flags=LayoutParams.FLAG_LAYOUT_NO_LIMITS | LayoutParams.FLAG_NOT_TOUCH_MODAL;

    return d;
}

So to sum it up, I want round corners, not 100% width of the screen, it preferably should wrap its content. Please, please, I need some help, I am really desperate about this, I´v ebeen trying it for days!

Answer 1

Well, I just found a solution, I am not really happy with it though.

I set the background (rounded_dialog.xml) for the dialog like this:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent"/>
<corners android:radius="10dp" />
<padding android:left="10dp" android:right="10dp"/>
</shape>

Then I set this to my dialog in its ´onCreateView´ method this way below. The rounded corners are not really necessary in this piece of code as the background is transparent, but the padding is important, because the dialog is still in fact as wide as the screen, but the padding makes it look like it is not.

getDialog().getWindow().setBackgroundDrawableResource(R.drawable.rounded_dialog);

And in the end I set background of the dialog´s components to another custom drawable which makes the corners round. I have a LinearLayout with RelativeLayout at the top and TextView at the bottom, so I set @null to the parent LinearLayout and set two different custom drawables to the two parts, one of which has rounded bottomCorners and the other one topCorners.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" 
android:background="@drawable/title_round"  
>

<RelativeLayout
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"        
    android:orientation="horizontal" 
    android:background="@drawable/blue_title_round_top"
    android:paddingTop="4dp"
    android:paddingBottom="4dp"
    >
<TextView 
    android:id="@+id/calendarHint"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/rounded_bottom"
    android:layout_gravity="center"
    android:gravity="center"
        />
</LinearLayout>

I believe there is a more proper solution to this as this is correct just visually, not really functionally, but enough correct for this case.
