我想在android中连接2个图像。例子,

在此处输入图像描述

在此处输入图像描述

我希望他们是这样的, 在此处输入图像描述

我已经通过硬编码完成了。首先我找到绿色图像的左上角,然后找到绿色边的最左下角。我使用触摸事件的 event.gerRawX() 和 event.getRawY() 参数来完成。现在我知道这两点之间的 x 和 y 距离。我也为红色做类似的事情。现在,当绿色块靠近红色时,我只计算红色块的左上点是否靠近绿色块的左下角。如果是这样,我将绿色的/红色的一个翻译成另一个。但是对于相同尺寸的平板电脑或具有不同分辨率的手机,这种硬编码计算应该会失败。我只想知道如何概括解决方案。谢谢。

编辑:我尝试连接两个图像的 GameActivity 和 ImageInfo 类。我实际上有 6 个这样的图像。我想要连接它们。像图像 1 将连接到图像 2 和图像 2 到 3,依此类推。

游戏活动类

鉴于您提供的图像,以通用方式连接它们很简单,因为图像具有相同的宽度并且它们具有透明背景,这是这个想法:

1-您需要两个图像之间的重叠距离,您可以从底部或顶部图像计算

在此处输入图像描述

下图中的绿线应等于上图中的红线

底部图像

鉴于您的图像具有透明背景,您可以轻松计算此距离,我将在此处使用底部图像。

这个想法是检查底部位图的最后一列中的每个像素(即宽度 - 1),并在遇到不透明像素时停止。

 private int getOverlapDistance(Bitmap bottomBitmap) {
    int height = bottomBitmap.getHeight();
    int width = bottomBitmap.getWidth();
    int distance = 0;
    for (int i = 0; i < height; i++) {
        if (Color.alpha(bottomBitmap.getPixel(width - 1, i)) != 0) {
            distance = (i + 1);
            break;
        }
    }
    return distance;
}

要连接它们,您可以执行以下操作(假设您ImageView将顶部和底部图像分开):

bitmap = ((BitmapDrawable) bottomImage.getDrawable()).getBitmap();
int overlapDistance = getOverlapDistance(bitmap);
bottomImage.setTop(topImage.getBottom() - overlapDistance);

实际上我用一个简单的活动尝试了这个并且它正在工作,这是连接两个图像之前和之后的样子:

连接前的图像

connect我只是在单击按钮时执行上面的代码

连接后
