    For some reason the solution of Midverse Engineer does not give me always correct results (at least on some Android versions). The solution of Sherif elKhatib works, but has the side effect of changing MeasuredWidth and Height. This could lead to incorrect positioning of the textView.

    My solution:

    width = textView.getPaint().measureText(text);
    metrics = textView.getPaint().getFontMetrics();
    height = metrics.bottom - metrics.top;

    Using the TextView inner Paing class is not so hot when you have multiple lines of text and different paddings. So stop trying to reinvent the wheel. Use getMeasuredHeight and getMeasuredWidth methods after calling measure(UNSPECIFIED, UNSPECIFIED). Just don't forget to get the new values inside the post, otherwise mostly you'll get a wrong result.

    tv.setText(state.s);
    tv.measure(UNSPECIFIED,UNSPECIFIED);
    tv.post(new Runnable() {
        @Override
        public void run() {
           Log.d("tv","Height = "+tv.getMeasuredHeight());
           Log.d("tv","Width  = "+tv.getMeasuredWidth());
        }
    });

    If your textview is called TV

    TV.setText("bla");
    TV.measure(0, 0);       //must call measure!
    TV.getMeasuredHeight(); //get height
    TV.getMeasuredWidth();  //get width

    Rect bounds = new Rect();
    
    textView.getPaint().getTextBounds(textView.getText().toString(), 0, textView.getText().length(), bounds);
    

    bounds.width() will give you the accurate width of the text in the Text View.
