问题 I have designed a listview by inflating each row using inflater and I have changed color of convertView's elements on their click events. But after scrolling the list the elements loss these changes. How can I "preserve" their state and represent them?

问题 I have a ListView that contains multiple ListView items. The ListView items Layout contains an ImageView. I use this ImageView as a button. When the button is clicked it changes the ImageView from a gray image to a green image. But when I scroll the ImageView out of visible view and then back to it, it returns to its original color. When the ImageView is created it can be either green or gray, it depends on a JSON array. So if an image is green and clicked it turns to gray. Then when its out
