How to change the width of an EditText object programmatically?

Question

I'd like to change the width of an EditText object programmatically without creating the view with xml before.

public class TableFragment extends Fragment{

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState){
    View view = inflater.inflate(R.layout.fragment_table, container, false);

    DisplayMetrics displayMetrics = new DisplayMetrics();
    getActivity().getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    int dHeight = displayMetrics.heightPixels;
    int dWidth = displayMetrics.widthPixels;

    TableLayout tableLayout = view.findViewById(R.id.tableLayout);
    EditText editTextSpieler1 = new EditText(getActivity());
    LayoutParams layoutparams = new LayoutParams(
            dWidth/4,
            WRAP_CONTENT);
    editTextSpieler1.setHint("Name");
    editTextSpieler1.setLayoutParams(layoutparams);
    tableLayout.addView(editTextSpieler1);

    return view;
}}

When creating the EditText view with xml and creating the object with findViewById setting the width works just fine. Yet when I start up the app with the code shown above, the EditText object's width is 100% of the display width.(instead of 25%)

Thanks in advance.

Solution:

tableLayout.addView(editTextSpieler1);
editTextSpieler1.getLayoutParams().width=((int)dWidth/4);

Chnaging the width of the view after it's being addded worked.

You can use

editTextSpieler1.getLayoutParams().width=((int)dWidth/4);

or

editTextSpieler1.getLayoutParams().width=200;

Same result, still at 100% width – May 09 '18 at 10:40
still not working, may the Fragment cause these problems? – May 09 '18 at 10:52

That helped. I apologize, I didn't understand that the width cannot be changed before the view is added :P – May 09 '18 at 11:04

Try the following:

int width = 100;
int height = 50;
LayoutParams params = new LayoutParams(width, height);
EditText mEditText = new EditText(this);
mEditText.setLayoutParams(params);

The height changed, but not the width, still at 100% display width. I also can't use "this" since this is a fragment. – May 09 '18 at 10:48
double check if the width is hard coded somewhere in the XML – Thorvald May 09 '18 at 15:36
