忘了提及的ImageView包含由XML布局文件提供了另一种形象

forgot to mention that imageview contains another image provided by xml layout file

推荐答案

按照惯例，你应该使用 setImageResource（R.drawable.img1）; （或 setImageDrawable（getResources（）getDrawable（R.drawable.img1））; ）代替 setBackgroundResource的（R.drawable.img1）; 。

By convention, you should be using setImageResource(R.drawable.img1); (or setImageDrawable(getResources().getDrawable(R.drawable.img1));) instead of setBackgroundResource(R.drawable.img1);.
