Android button.setWidth() not doing anything

Issue

I have a inputMethodService that controls a soft keyboard. Here is the relevant part of the

@Override
public View onCreateInputView() {
    LayoutInflater lInflate = getLayoutInflater();
    Resources res = getResources();


    LinearLayout inputView = (LinearLayout) lInflate.inflate(R.layout.copypasta, null);

    Button tab_navySeal = (Button) inputView.findViewById(R.id.tab_navySeal);
    Button tab_thatsome = (Button) inputView.findViewById(R.id.tab_thatsome);
    Button tab_thethingis = (Button) inputView.findViewById(R.id.tab_thethinggis);
    Button tab_identify = (Button) inputView.findViewById(R.id.tab_identify);
    Button tab_othercopypasta = (Button) inputView.findViewById(R.id.tab_otherpasta); 


    int sW = res.getDisplayMetrics().widthPixels;

    int bWidth = sW/5;
    Log.i("DEBUG_TAG", Integer.toString(bWidth));
    if(bWidth > 100) {
        tab_navySeal.setWidth(bWidth);
        tab_identify.setWidth(bWidth);
        tab_thatsome.setWidth(bWidth);
        tab_thethingis.setWidth(bWidth);
        tab_othercopypasta.setWidth(bWidth);

    }

    return inputView;
}

The purpose of this code is so that if the screen is large enough the buttons will each be 1/5 of the screen's width. Otherwise if the screen is small, the buttons will just be 100dp (which is fine since they are wrapped in a HorizontalScrollView).

However nothing is actually happening when I open the softkeyboard.

Here is an image of the problem:

The buttons at the top should each be 1/5 of the screen instead of being 100dp wide. Incase this matters, the width of each button is set to 100dp in XML (even though I don't think it matters, because programmatically setting the widths should override the XML).

Solution

You can try setting LayoutParams with the new width like this -

tab_navySeal.setLayoutParams (new LayoutParams(bWidth, LayoutParams.WRAP_CONTENT);
