Answer 1

Use following code. it worked for me

float rotation = 30.0f;

     Bitmap bitmap = your bitmap
     Rect rect = new Rect(100,100,bitmap.width, bitmap.height);
     Matrix matrix = new Matrix();
     float px = rect.exactCenterX();
     float py = rect.exactCenterY();
     matrix.postTranslate(-bitmap.getWidth()/2, -bitmap.getHeight()/2);
     matrix.postRotate(rotation);
     matrix.postTranslate(px, py);
     canvas.drawBitmap(bitmap, matrix, null);
     matrix.reset();
     invalidate();
