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。
此刻我使用此代码
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;
}
不好的是,它实际上与我的smartfon的身高,体重和dpi有关。
当我使用5英寸屏幕和6英寸屏幕的智能手机时,它不同,无论不同的屏幕,这必须是相同的。
感谢帮助!
试试这段代码:
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;
}
