Android UI設計–新聞或資訊條數的實現

例如簡訊或者新聞的條數經常做在圖片之上，實現方式如下，可以根據不同的圖片大小進行調節

    private Bitmap generateNumberIcon(int resId, int newsCount){    Bitmap icon = BitmapFactory.decodeResource(getResources(), resId);    int iconSize = icon.getWidth();    Bitmap mBitmap = Bitmap.createBitmap(iconSize, iconSize, Config.ARGB_8888);    Canvas canvas = new Canvas(mBitmap);        Paint paint = new Paint();    paint.setDither(true);    paint.setFilterBitmap(true);    Rect src = new Rect(0, 0, iconSize, iconSize);    Rect dst = new Rect(0, 0,iconSize, iconSize);    canvas.drawBitmap(icon, src, dst, paint);    Paint countPaint = new Paint(Paint.ANTI_ALIAS_FLAG|Paint.DEV_KERN_TEXT_FLAG);    countPaint.setColor(getResources().getColor(R.color.red));    countPaint.setStyle(Paint.Style.STROKE);    countPaint.setTypeface(Typeface.DEFAULT_BOLD);        countPaint.setTextSize(iconSize*2/3f);    canvas.drawText(String.valueOf(newsCount),iconSize/4 , iconSize*5/6, countPaint);    return mBitmap;    }
