android - converting text string to image -

i converting text string image in android application. following various posts on so, have written code. doesn't display image. there wrong code?

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);        et = (edittext) findviewbyid(r.id.edittext1);      iv = (imageview) findviewbyid(r.id.imageview1);      btn = (button) findviewbyid(r.id.button1);        btn.setonclicklistener(new onclicklistener(){          @override         public void onclick(view v) {             // todo auto-generated method stub              string text = et.gettext().tostring();               byte[] data = null;             try {                 data = text.getbytes("utf-8");             } catch (unsupportedencodingexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }              final string base64 = base64.encodetostring(data, base64.default);             bitmap bit = stringtobitmap(base64);             iv.setimagebitmap(bit);          }      });  }   public bitmap stringtobitmap(string encodedstring){      try{        byte [] encodebyte=base64.decode(encodedstring,base64.default);        bitmap bitmap=bitmapfactory.decodebytearray(encodebyte, 0, encodebyte.length);        return bitmap;      }catch(exception e){        e.getmessage();        return null;      }       } 

try convert byte[] image:

bitmap bit = bitmapfactory.decodebytearray(data, 0, data.length); 

there's no reason why should encode byte array base64 decode back.

although real question is: in edittext? image converted string, or text you're trying display?

if it's image, above work.

if not, wrong approach , sounds need do, foamyguy said in comments, draw text onto imageview's canvas: https://stackoverflow.com/a/10923478/1426565

although, if have text, why not display in textview , customize textview display how want (ie. font size, color, background, etc)? better approach. if you're unsure of how use textview, check out: http://developer.android.com/reference/android/widget/textview.html
