hi everybody,

I wanted to draw components on canvas. Drawing colorful text on is completely done with layouts of android. In below picture, i have put some colorful text on bitmap through layout. But need to implement same on canvas. How to do this with canvas?

Thanks a lot of

Hi nisha,

Here's an example of drawing on the canvas of a bitmap. Once you have a bitmap, you can place it on the screen just like any other image, or send it or whatever. You can also use this same technique to draw in the ondraw method of a view.

Code: Select all

          public Bitmap buildUpdateTime(String time) { Bitmap myBitmap = Bitmap.createBitmap(160, 84, Bitmap.Config.ARGB_4444);;
              Canvas myCanvas = new Canvas(myBitmap);
              Paint paint = new Paint();
                                        //To use own font
              //Typeface clock = Typeface.createFromAsset(this.getAssets(),"Carre.ttf");
              paint.setAntiAlias(true);
              paint.setSubpixelText(true);
              paint.setTypeface(clock);
              paint.setStyle(Paint.Style.FILL);
              paint.setColor(Color.RED);
              paint.setTextSize(65);
              paint.setTextAlign(Align.CENTER);
              myCanvas.drawText(time, 80, 60, paint);
              return myBitmap;             
          }


Hope this helps.
