Show marker inside a resource drawable which obtained from url
Here is the map page I have, which shows all the users of my App. Also the images(markers) are obtained from the URL given from my server. These markers has to put inside a Drawable(a circle like image as shown). I created a circle like Bitmap from the url using Canvas.
public Drawable showMe(String url)
{
Bitmap bitmap=null;
try {
URL newurl = new URL(url);
bitmap = BitmapFactory.decodeStream(newurl.openConnection().getInputStream());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
bitmap=getBitmap(url);
Paint paint = new Paint();
paint.setFilterBitmap(true);
int targetWidth = 30;
int targetHeight = 30;
Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight,Bitmap.Config.ARGB_8888);
RectF rectf = new RectF(0, 0, 30, 30);
Canvas canvas = new Canvas(targetBitmap);
Path path = new Path();
path.addRoundRect(rectf, targetWidth, targetHeight, Path.Direction.CW);
canvas.clipPath(path);
canvas.drawBitmap( bitmap, new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight()),
new Rect(0, 0, targetWidth, targetHeight), paint);
Matrix matrix = new Matrix();
matrix.postScale(1f, 1f);
Bitmap resizedBitmap = Bitmap.createBitmap(targetBitmap, 0, 0, 30, 30, matrix, true);
Bitmap bitmap_circle=mergeBitmaps(resizedBitmap);
BitmapDrawable bd = new BitmapDrawable(bitmap_circle);
return bd;
}
The above function will create the final drawable for the marker.Also the mergeBitmaps() function merge the both the resource drawable and the bit map together..
public Bitmap mergeBitmaps(Bitmap manBitmap){
try{
Bitmap markerBitmap = BitmapFactory.decodeResource( this.getResources(), R.drawable.circle_bg);
Bitmap bmOverlay = Bitmap.createBitmap(markerBitmap.getWidth(), markerBitmap.getHeight(), markerBitmap.getConfig());
Canvas canvas = new Canvas(bmOverlay);
Matrix matrix = new Matrix();
matrix.postScale(1f, 1f);
canvas.drawBitmap(markerBitmap, matrix, null);
canvas.drawBitmap(manBitmap, 5, 5, null);
return bmOverlay;
}
catch(Exception ex){
ex.printStackTrace();
return null;
}
}
But the problem is, this bitmap is not best fit inside the background Drawable in order to get a feeling that both together will give a single image.
Can anyone help me ?
change
canvas.drawBitmap(manBitmap, 5, 5, null);
to smtg like
canvas.drawBitmap(manBitmap, (markerBitmap.getWidth()-manbitmap.getWidth())/2,
(markerBitmap.getHeight()-manbitmap.getHeight())/2, null);
