这个不行 因为:
2~
i.setImageURI(mUrls[position]);
i.setScaleType(ImageView.ScaleType.FIT_XY);
i.setLayoutParams(new Gallery.LayoutParams(260, 210));可以得到制定URL的image
并且在界面里可以显示
而用1~代码
i.buildDrawingCache();
Bitmap bitmap = i.getDrawingCache();已转化为bitmap
在用i.setImageBitmap(bitmap)
就显示不出来了
顺便提一下 打算通过选择的image转化为bitmap在另一个gallery中显示谢谢大家帮忙 散分是必须的!
