How To Position Dialog underneath a Button, Android Studio?

Question

How would I open my dialog so its in a set position below a Button widget?

This is what I have so far:

    public void showPopup(View v){

    mDialog.setContentView(R.layout.dialog_custom_workout_info);
    Window window = mDialog.getWindow();
    window.setLayout(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    window.setGravity(Gravity.CENTER_HORIZONTAL);
    window.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
    mDialog.getWindow().setDimAmount(0);
    mDialog.show();

}

The Dialog opens, but I can only use the gravity to center it, but I would like it opening at a set position relative to another widget ( in this case the widget is labelled "imageButton".

Thanks in advance!

There is an x,y available for position of the dialog, could you use some offset from the x,y of the button you want to position it under? I am sure there are other ways but if it works there is not much modification to your existing code

position of a control

            Dialog d = DialogAbout.create(this);
            Button b = findViewById(R.id.pick_button);
            // Absolute coordinates
            int[] location = new int[2];
            b.getLocationOnScreen(location);
            int x = location[0];
            int y = location[1];

           // Coordinates relative to parent
            int bx = b.getLeft();
            int by = b.getTop();

            Window window = d.getWindow();

            WindowManager.LayoutParams wlp = window.getAttributes();
            // set the new location [you will need to play with this]
            wlp.x = x;
            wlp.y = (y - b.getHeight());

            // add to your window
            window.setAttributes(wlp);

Thanks for the reply, would you be able to give me an example of how I would go about this? As I cannot seem to find an example online of how I would apply the position of the dialog relative to the button widget. – Ajay Taak Mar 11 '19 at 00:31

Just implemented this snippet of code you provided and played around with it, finally got the result I was looking for.. Thank you! – Ajay Taak Mar 12 '19 at 10:52
what is bx and by used for? – Yohanim Aug 05 '21 at 16:17
this is an old answer constraint layouts do this in a more modern and flexible way the coordinates are if you want the position relative to the parent – keepTrackOfYourStack Aug 06 '21 at 19:39
