我想在activity中改变图片视图的宽高属性,但是我用了下面的方法后没有实现:
View card_view = getLayoutInflater().inflate(R.layout.card_details1,null);
coupon_img = (ImageView) card_view.findViewById(R.id.coupon_image);
// I tried this ////////
coupon_img.getLayoutParams().height = 20;
coupon_img.getLayoutParams().width = 20;
// I also tried this ////
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(100, 100);
coupon_img.setLayoutParams(layoutParams);
// also this one ////
coupon_img.setMaxHeight(10);
不知道为什么?应该怎么改才对呢?谢谢。
