How to make DialogFragment width to Fill_Parent

This is the solution I figured out to handle this issue:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);    
    dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);

    return dialog;
}

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

    Dialog dialog = getDialog();
    if (dialog != null) {
       dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
       dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    }
}

Edit:

You can use the code below in onCrateView method of Fragment before return the inflated view.

getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
