问题 I want to make a UI element like a GridView , I want it's complete functionality but want it to be horizontally scrollable rather than vertically.

问题 I am working on a small Android app. Part of what I need for this android app is to have a grid that is both horizontally and vertically scroll-able. However, the leftmost column needs to be frozen (always on screen, and not part of the horizontal scrolling). Similarly, the top header row needs to be frozen (not part of the vertical scrolling) This picture will hopefully describe this clearly if the above doesn't make too much sense: Key : White: Do not scroll at all Blue: scroll vertically

问题 I have a GridView implemented and activated the mGridView.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL); mode. Now I have the possibility to select multiple items from my grid when I perform a long click on one item. I want to achieve this behavior on a normal, short click. Is this possible? 回答1: First, I'd suggest to think if this user scenario is what you have been looking for.

问题 I need help to add a space inside a GridView at the bottom of it. This Space should be below the last Element of the GridView, inside of it. This space shouldn't work like a margin to the next element, it should be only visible, when the user scrolles to the bottom of the GridView. The reason for this is an ad banner which partly covers the bottom of the GridView. Besides this obstruction, the user should still be able to see the whole content of the GridView, that's why the space at the
