我想下载一个图像(大小未知,但总是大致正方形)并显示它以使其水平填充屏幕,并垂直拉伸以保持图像的宽高比,在任何屏幕尺寸上.这是我的(非工作)代码.它水平拉伸图像,但不垂直,因此被压扁...
ImageView mainImageView = new ImageView(context);
mainImageView.setImageBitmap(mainImage); //downloaded from server
mainImageView.setScaleType(ScaleType.FIT_XY);
//mainImageView.setAdjustViewBounds(true);
//with this line enabled, just scales image down
addView(mainImageView,new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
