Scrollview - Scroll codeTo not working properly

Question

Well, according to the title, I’m having trouble solving a problem in my code, the line to textView that Scrollview brings through scrollTo code. When I press the button he does not show me the line I wish:

btbuscar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

int indexOfCriteria = (fullText[0].indexOf(criteria));
int lineNumber = (TEXT.getLayout().getLineForOffset(indexOfCriteria));
myscroll.scrollTo(0, TEXT.getLayout().getLineTop(lineNumber));});

And by pressing the button it does not leave the searched attribute in the correct line.

From now on I thank those who can collaborate.
