Android：从两个位图创建图像，位图下的位图

我想要的：使用两个位图创建图像，在第一个位图下放置第二个位图。

此时我使用此代码

public static Bitmap combineImages(Bitmap background, Bitmap foreground, float disFromTheTopPercent) {

        int width = background.getWidth(), height = background.getHeight();
        Bitmap cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas comboImage = new Canvas(cs);
        background = Bitmap.createScaledBitmap(background, width, height, true);
        comboImage.drawBitmap(background, 0, 0, null);

        int top = (int) (disFromTheTopPercent * height);
        int left = 0;

        comboImage.drawBitmap(foreground, left, top, null);

        return cs;
    }

糟糕的是，它实际上与我的smartfon的身高、体重和dpi有关

当我将smartfone与5英寸屏幕和6英寸屏幕一起使用时，它是不同的，无论屏幕如何，它都必须看起来相同

谢谢你的帮助

请尝试以下代码：

public static Bitmap combineImages(Bitmap c, Bitmap s) {
    Bitmap cs;
    int width, height;

    width = s.getWidth();
    height = c.getHeight() + s.getHeight();

    cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

    Canvas comboImage = new Canvas(cs);

    comboImage.drawBitmap(c, 0f, 0f, null);
    comboImage.drawBitmap(s, 0f, c.getHeight(), null);

    return cs;
}
