Comment puis-je ajouter la méthode Round Corner pour bitmap dans mon imageview android?

Question

Gud Amis du matin. J'ai créé Imageview dans la rangée de listview. Je tournerai ma bitmap dans mon Imageview comme,

public View getView(final int position, View convertView, ViewGroup parent) { 
    View row = convertView; 
    UserHolder holder = null; 
    Log.d("main", "pos:" + "" + position); 

      if (row == null) { 
     LayoutInflater inflater = ((Activity) context).getLayoutInflater(); 
     row = inflater.inflate(layoutResourceId, parent, false); 
     holder = new UserHolder(); 
     holder.Name = (TextView) row.findViewById(R.id.name); 

     holder.Number = (TextView) row.findViewById(R.id.number); 

     holder.img=(ImageView) row.findViewById(R.id.image); 


     Typeface face=Typeface.createFromAsset(context.getAssets(),"helve.ttf"); 

     holder.Name.setTypeface(face); 
     //holder.Number.setTypeface(face); 

     //bit = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);  
     // 

     //holder.img.setImageBitmap(getRoundedCornerBitmap(bit, 40)); 

     row.setTag(holder); 
    } else { 
     holder = (UserHolder) row.getTag(); 
    } 
    User user = data.get(position); 

    holder.Name.setText(user.getName()); 
    //holder.img.setImageBitmap(user.getbi()); 
    holder.img.setImageBitmap(roundCornerImage(user.getbi(),50)); 
    //holder.img.setImageBitmap(roundCornerImage(BitmapFactory.decodeResource(user.getbi(), R.drawable.ic_launcher),60)); 
    holder.Number.setText(user.getNumber()); 




    // Give Different Back Ground To List View--------------------------------------------- 

    if ((position % 2) == 0) { 
     row.setBackgroundResource(R.drawable.list_dark); 
    } else { 
     row.setBackgroundResource(R.drawable.list_light); 
    } 




    Log.d("main", "pos:" + "" + position); 

    return row;

Maintenant, je veux mettre Bitmap Méthode Mon Cette imageview. avec mon code. Les méthodes que je veux ajouter sont ci-dessous.

public Bitmap roundCornerImage(Bitmap src, float round) { 
    // Source image size 
    int width = src.getWidth(); 
    int height = src.getHeight(); 
    // create result bitmap output 
    Bitmap result = Bitmap.createBitmap(width, height, Config.ARGB_8888); 
    // set canvas for painting 
    Canvas canvas = new Canvas(result); 
    canvas.drawARGB(0, 0, 0, 0); 

    // configure paint 
    final Paint paint = new Paint(); 
    paint.setAntiAlias(true); 
    //paint.setColor); 


    // configure rectangle for embedding 
    final Rect rect = new Rect(0, 0, width, height); 
    final RectF rectF = new RectF(rect); 

    // draw Round rectangle to canvas 
    canvas.drawRoundRect(rectF, round, round, paint); 

    // create Xfer mode 
    paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN)); 
    // draw source image to canvas 
    canvas.drawBitmap(src, rect, rect, paint); 

    // return final image 
    return result; 
}

Comment puis-je ajouter cette méthode dans mon code. Merci d'avance.

Answer 1

Essayez ci-dessous le code:

holder.img.setImageBitmap(roundCornerImage(user.getbi(),ANY CONSTANT VALUE TO MAKE YOUR IMAGEVIEW ROUND LIKE-1,2)); 

Answer 2

Vous pouvez Ussé cette méthode dans adaptor--

public Bitmap getRoundedRectBitmap(Bitmap scalebitmap, int pixels) { 
     Bitmap targetBitmap = null; 
     try { 

      int targetWidth = 150; 
      int targetHeight = 150; 
      targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight, 
        Bitmap.Config.ARGB_8888); 
      Canvas canvas = new Canvas(targetBitmap); 
      Path path = new Path(); 
      path.addCircle(
        ((float) targetWidth)/2, 
        ((float) targetHeight)/2, 
        (Math.min(((float) targetWidth), ((float) targetHeight))/2), 
        Path.Direction.CW); 
      Paint paint = new Paint(); 
      paint.setColor(Color.GRAY); 
      // paint.setStyle(Paint.Style.STROKE); 
      paint.setStyle(Paint.Style.FILL); 
      paint.setAntiAlias(true); 
      paint.setDither(true); 
      paint.setFilterBitmap(true); 
      canvas.drawOval(new RectF(0, 0, targetWidth, targetHeight), paint); 
      // paint.setColor(Color.TRANSPARENT); 
      canvas.clipPath(path); 
      Bitmap sourceBitmap = scalebitmap; 
      canvas.drawBitmap(
        sourceBitmap, 
        new Rect(0, 0, sourceBitmap.getWidth(), sourceBitmap 
          .getHeight()), new RectF(0, 0, targetWidth, 
          targetHeight), paint); 

     } catch (NullPointerException e) { 
      e.printStackTrace(); 
     } catch (OutOfMemoryError o) { 
      o.printStackTrace(); 
     } 
     return targetBitmap; 
    } 

Et vous pouvez écrire dans une méthode constante de classe et appeler cette méthode dans l'adaptateur comme // photo est l'image bitmap que vous voulez convertir en rond

Bitmap bitmapImage = Bitmap.createScaledBitmap(photo, 200, 200,true); 
    bitmap = imageprocessing.getRoundedRectBitmap(bitmapImage, 100);
