I am new to Android.. I have a textview with size 250dp.. I am trying to calculate the text width inside it.. But I could not find any API that returns the actual content width.. Can someone help how it can be done. Thanks in advance.

  • @alex.. Do you mean getMeasuredWidth() returns the actual content width? – user4582135 Feb 20 '15 at 03:51

You can use the Paint object held by the TextView to measure the width of the text contents:

CharSequence text = textView.getText();
float width = textView.getPaint().measureText(text, 0, text.length());

There is also a version that measures the full bounds (left/right/top/bottom) of the text contents:

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

//bounds now contains the rect of the actual text string
int width = bounds.getWidth();

The Devunwired answer is completely right.

However, it's useful the reader to know that the text width measure in pixels don't need to be linked with any real content of a TextView or EditText and isn't restricted to the view widht, so one can simulate if a determinated text fits well in the view before set the view with a text.

Besides, if one uses the whole string you don't need to specify a initial index and a final index (exclusive).

So one can write

float width = textView.getPaint().measureText("my favorite fruit is a banana");

It works smoothly

There is no API for this.first you have to find the text size and find lenth of string.finally multipl both you will get width of text in textview.
