原问题描述:我想在activity中改变图片视图的宽高属性,但是我用了一个方法后没有实现,应该要怎么实现呢?
解决方案:
在这段代码中,创建了一个新的实例并且设置了尺寸:
// SET THE IMAGEVIEW DIMENSIONSint dimens = 120;float density = activity.getResources().getDisplayMetrics().density;int finalDimens = (int)(dimens * density);LinearLayout.LayoutParams imgvwDimens = new LinearLayout.LayoutParams(finalDimens, finalDimens);imgAlbumPhoto.setLayoutParams(imgvwDimens);// SET SCALETYPEimgAlbumPhoto.setScaleType(ScaleType.CENTER_CROP);// SET THE MARGINint dimensMargin = 5;float densityMargin = activity.getResources().getDisplayMetrics().density;int finalDimensMargin = (int)(dimensMargin * densityMargin);LinearLayout.LayoutParams imgvwMargin = new LinearLayout.LayoutParams(finalDimens, finalDimens);imgvwMargin.setMargins(finalDimensMargin, finalDimensMargin, finalDimensMargin, finalDimensMargin);
改变已存在的ImageView尺寸,使用这个:
coupon_img.setLayoutParams(new LayoutParams(100, 100));
