Auto Adjust Textview Android

Question

I finally found the code to resize the text based on the height of the textview.Source, but i am not getting how to pass the text in this function,my text is cmoing from another intent

public int getHeightOfMultiLineText(String text,int textSize, int maxWidth) {
        TextPaint paint = new TextPaint();
        paint.setTextSize(textSize);
        int index = 0;
        int linecount = 0;
        while(index < text.length()) {
            index += paint.breakText(text,index,text.length(),true,maxWidth,null);
            linecount++;
        }

        Rect bounds = new Rect();
        paint.getTextBounds("Yy", 0, 2, bounds);
        // obtain space between lines
        double lineSpacing = Math.max(0,((linecount - 1) * bounds.height()*0.25)); 

        return (int)Math.floor(lineSpacing + linecount * bounds.height());

    }

save the text in String and passed to getHeightofMultiLineText(ur_string_text,12,10); — KOTIOS, Jul 18 '13 at 05:51

Well you can get the text of TextView as String using urTextView.getText().toString()

TextView urTextView;
String text = urTextView.getText().toString();

int textSize = 100;
int maxHeight = 50;
while(getHeightOfMultiLineText(text,textSize,maxWidth) > maxHeight)
    textSize--;

This should work.

i am getting data like this tv.setText(receivingdata); how to pass to function – user2451541 Jul 18 '13 at 06:01
after receiving data, do `String text = tv.getText().toString();` and pass to function. – Ankit Aggarwal Jul 18 '13 at 06:04
then i have to remove tv.setText(receivingdata); – user2451541 Jul 18 '13 at 06:14
no, you won't have to. the text is set in the textview tv. All you have to do now is to use this text and change its size. So just add what I have posted, and then check. – Ankit Aggarwal Jul 18 '13 at 06:20
if i am fixed the textview size in xml suppose 50,then it is setting the text to 50 not checking the int textSize = 100;,i am calling this function in main()? – user2451541 Jul 18 '13 at 06:26
This function should be called onCreate()... what do you mean by main()... this is android coding – Ankit Aggarwal Jul 18 '13 at 06:28
