Put a button over an ImageView

由 ＊爱你＆永不变心＊ 提交于 2019-11-27 14:36:18
问题 I'm newbie in Android. I would like to know if it's possible to put a button or another component over an ImageView. I've tried setting the image as a background image of a LinearLayout, but when I change between landscape and portrait mode, the image porportions are changed. Thanks a lot. 回答1: Don't put the image as a background, you don't have any control on how the image is scaled. Instead, create a RelativeLayout, and put an ImageView as one of the child, and you can place anything

Android ImageView ScaleType and item height

由 放肆的年华 提交于 2019-11-27 14:35:37
问题 Things looked quite simple first but in the end the result is not good. I have an image which has a width larger than screen's width. So I need to scale it down in my imageview. I looked over the ScaleType options and tried them all but none is ok. First "center" only displays the image centered on the layout, no scaling done. "fitCenter" scales the image to fit in my layout but has a major drawback: the height of the item remains as it would have the large image in it. Take a look at the

Android ScrollView adds extra padding on top and bottom of child imageview

由 南笙酒味 提交于 2019-11-27 13:01:51
问题 I have a problem with rendering a ScrollView. Essentially, the layout is fixed header and footer with a scrollview in the middle. The idea is that when the screen keyboard is activated for the content EditText the image can be scrolled if the height of the image is longer than the middle view. In testing the layout, I've found that on my Android phone (Xperia X10 Android 1.6) there is a whole heap of padding added to the top and bottom of the ImageView. I'd appreciate any suggestions as to
