【转】android ImageView 宽度设定，高度自适应

http://www.cnblogs.com/bcbr/articles/4268276.html

需求是，imageview 宽度充满屏幕，高度自适应

首先，需要给你的ImageView 

imageView.setAdjustViewBounds(true);

imageView.setScaleType(ScaleType.FIT_XY);

LayoutParams params = new LayoutParams(screenWidth, LayoutParams.WRAP_CONTENT);

imageView.setLayoutParams(params);

设置了setMaxWidth setMaxHeight后setAdjustViewBounds才有效

imageView.setMaxWidth(screenWidth);

imageView.setMaxHeight(screenWidth * 10);
