Question

Really stupid question here, but could not find an answer googling.

I have a clickable textview.
How to retrieve the row’s number that is clicked??

Answer 1

The question isn’t that stupid because there is no built-in method, that I know of, to do this.

However you can use:

• getLineHeight() to determine how tall each line is in the TextView and
• MotionEvent#getY() in an OnTouchListener to calculate which line was clicked.

Basic example:

textView.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP) {
            float line = FloatMath.floor(event.getY() / textView.getLineHeight());
            Toast.makeText(getBaseContext(), "" + line, Toast.LENGTH_SHORT).show();
        }
        return false;
    }
});

From the getLineHeight() documentation:

Note that markup within the text can cause individual lines to be taller or shorter than this height, and the layout may contain additional first- or last-line padding.

So if you have modified any attribute listed above, you’ll need to account for that as well.
