Android ImageView width setting, highly adaptive

Recently encountered a demand, the requirement is not aware of the picture width and height of the case, let the picture in the specified width, while highly adaptive, in the network to find a bit, there are many solutions, and then for their own application, chose a modified smaller scheme, and finally proved that the effect is pretty good, recorded here, Hope to help people with the same needs.

First, you need to add android:adjustviewbounds= "true" to your ImageView layout

< ImageView             Android:id = "@+id/iv_custom_showdress_item_dress"             android:layout_width= "Fill_parent"            android:layout_height= "Wrap_ Content "            android:adjustviewbounds=" true "/>

Then, set the ImageView in the code. Maximum width and maximum height, because the Adjustviewbounds property only works if the maximum height and maximum width are set

WindowManager wm = (WindowManager) _context.getsystemservice (context.window_service);             int screenwidth = wm.getdefaultdisplay (). getwidth ();             = viewHolder.showDress.getLayoutParams ();             = screenwidth;             = layoutparams.wrap_content;            VIEWHOLDER.SHOWDRESS.SETLAYOUTPARAMS (LP);
