Why setImeOptions doesn't work? Same for setTextSize

Question

My code:

TextView tv = new TextView(this);
final EditText newPositionName = new EditText(this);

newPositionName.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
newPositionName.setBackgroundColor(Color.TRANSPARENT);

I can't understand why setImeOptions doesn't work! setBackgroundColor works fine. Same for setTextSize. I've:

private Vector<TextView> ranking = new Vector<TextView>();
...
for(int i = 0; i < 5; i++){
    ranking.add(new TextView(this));
    ranking.lastElement().setTextSize(30);
}

But text size doesn't change.

As pointed out here: setImeOptions: why the "Done" button does not show on the soft keyboard? calling setSingleLine() on the TextEdit will enable the functionality.
