Answer 1

option 1. add following code in oncreate in activity

 getDialog().getWindow()
         .setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

or you can Create a custom style for Dialog

then use that style in dialog fragment

@Override public void onCreate(@Nullable Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setStyle(DialogFragment.STYLE_NORMAL, R.style.CustomDialog);
}

@Override public void onStart() {
  super.onStart();
  getDialog().getWindow()
    .setLayout(WindowManager.LayoutParams.MATCH_PARENT,
        WindowManager.LayoutParams.MATCH_PARENT);
}

SampleDialogFragment sampleDialogFragment = new SampleDialogFragment();
SampleDialogFragment.show(getActivity().getSupportFragmentManager(), "sometag");

OR you try the following code in style will help you

@null

Solution 2: dialog.window.setLayout

class TestDialog : DialogFragment() {

    override fun onStart() {
        super.onStart()

        dialog?.window?.setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT)
    }

}
