Question

我需要将图像与另一个图像重叠。以下是我的代码

int cards[] = {R.drawable.c1,R.drawable.c2,R.drawable.c3,R.drawable.c4,R.drawable.c5,R.drawable.c6,
            R.drawable.c7,R.drawable.c8,R.drawable.c9,R.drawable.c10,R.drawable.c11,R.drawable.c12,R.drawable.c13};

    ImageView[] Images = new ImageView[cards.length];
        for (int i = 0; i < cards.length; i++) {           
            Images[i] = new ImageView(this);

            Images[i].setImageBitmap(BitmapFactory.decodeResource(getResources(), cards[i]));
            Images[i].setId(i);
            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            if (i != 0) {                
                params.addRule(RelativeLayout.RIGHT_OF,Images[i - 1].getId());
              params.addRule(RelativeLayout.ALIGN_PARENT_TOP, Images[i - 1].getId());
              layout.addView(Images[i], params);
            } else {
                params.addRule(RelativeLayout.LEFT_OF,Images[0].getId());
                params.rightMargin=10;
                layout.addView(Images[i]);
            }

       }

有了这个，我无法显示第一张图像，剩余的图像显示但不与其他图像重叠。如何解决这个问题？

解决问题

ImageView[] Images = new ImageView[cards.length];
        for (int i = 0; i < cards.length; i++) {           
            Images[i] = new ImageView(this);

            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
            if (i != 0) {          
                 params.addRule(RelativeLayout.ALIGN_TOP, i-1);
                 params.addRule(RelativeLayout.ALIGN_LEFT,i-1);
                 params.leftMargin= 40;
                 Images[i].setImageBitmap(BitmapFactory.decodeResource(getResources(), cards[i]));
                 Images[i].setId(i);
                layout.addView(Images[i], params);
            } else {
                 Images[i].setImageBitmap(BitmapFactory.decodeResource(getResources(), cards[i]));
                 Images[i].setId(i);
                layout.addView(Images[i], params);
            }

        }

Answer 2

代码完全错误:)你知道RIGHT_OF和LEFT_OF是什么意思吗？只需删除所有if else部分，你应该看到所有te图像一个在另一个之上。顺便说一下，有更好的方法可以像在LayerDrawable类上一样在Android上堆叠图像。
