Android图片重叠效果绘制图片

如图所示,在友盟分享的时候需要图中所示的图片,但是里面的图片是四张图片拼接起来的,因为牌谱的颜色随时可能更换,所以图片是不固定的,花色也需要随时更换,上代码;

public Bitmap first() {
        // 防止出现Immutable bitmap passed to Canvas constructor错误
         Bitmap bitmap1 = BitmapFactory.decodeResource(getResources(),
                 R.drawable.chouma).copy(Bitmap.Config.ARGB_8888, true);
//        Bitmap bitmap1 = ((BitmapDrawable) getResources().getDrawable(
//                R.drawable.chouma)).getBitmap();

        Bitmap bitmaptest = ((BitmapDrawable) getResources().getDrawable(
                R.drawable.chouma)).getBitmap();


         Bitmap bitmap2 = ((BitmapDrawable) getResources().getDrawable(
          R.drawable.bh2)).getBitmap();

        Bitmap bitmapfirst = rotateBitmaps(bitmap2,10);
        Bitmap bitmaotest = rotateBitmap(bitmaptest,0);
       Bitmap backmap =  rotateBitmaps(bitmap1,-30);

        Bitmap bitmap3 = ((BitmapDrawable) getResources().getDrawable(
                R.drawable.fk1)).getBitmap();

        Bitmap bitmsecond = rotateBitmaps(bitmap3,-20);


         Bitmap newBitmap = null;
         newBitmap = Bitmap.createBitmap(backmap);
         Canvas canvas = new Canvas(newBitmap);
         Paint paint = new Paint();
         int w = backmap.getWidth();
         int h = backmap.getHeight();
         int w_2 = bitmapfirst.getWidth();
         int h_2 = bitmapfirst.getHeight();
        int w_3 = bitmsecond.getWidth();
        int h_3 = bitmsecond.getHeight();
        paint.setColor(Color.GRAY);
        paint.setAlpha(0);
//        Log.e("yinshi","bitmap1.getWidth()"+bitmap1.getWidth()/2+"bitmap1.getHeight()"+bitmap1.getHeight()/2);
        canvas.drawRect(0, 0, backmap.getWidth()/2, backmap.getHeight()/2, paint);
//        canvas.drawRect(0, 0, 0, 0, paint);
        paint = new Paint();
//        Log.e("yinshi","----Math.abs(w_2 - w_3) / 4----"+Math.abs(w_2 - w_3) / 4+"-----Math.abs(h - h_3) / 4---"+Math.abs(h - h_3) / 4);
        canvas.drawBitmap(bitmaotest,Math.abs(w - w_2)/2, 25, paint);
        canvas.drawBitmap(bitmsecond, Math.abs(w_2 - w_3) /2, -7, paint);
        canvas.drawBitmap(bitmapfirst, Math.abs(w - w_2), -6, paint);

          canvas.save(Canvas.ALL_SAVE_FLAG);     // 存储新合成的图片
//            canvas.translate(0,600);
          canvas.restore();
        return newBitmap;
    }

图中的花色我暂时是写死的,练习demo,花色是可以根据服务器的数据进行更换的

拼接图中花色的旋转动画效果

public static Bitmap rotateBitmap(Bitmap bitmap, int degrees) {
        if (degrees == 0 || null == bitmap) {
            return bitmap;
        }
        Matrix matrix = new Matrix();
//        Log.e("yinshi","bitmap.getWidth() / 2-----"+bitmap.getWidth() / 2+"----bitmap.getHeight() / 2---"+bitmap.getHeight() / 2);
//        matrix.preTranslate(1,1.5f);

        matrix.postRotate(degrees, bitmap.getWidth() / 3, bitmap.getHeight() / 3);
//        matrix.postTranslate(0,bitmap.getHeight());
//        matrix.preTranslate(0,bitmap.getHeight());
        matrix.setTranslate(0,200);
        Bitmap bmp = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
//        Log.e("yinshi","bitmap.getWidth()"+bitmap.getWidth()+"bitmap.getHeight()"+bitmap.getHeight());
        if (null != bitmap) {
            bitmap.recycle();
        }

        return bmp;
    }
