android-listview

问题 So, right now I have a custom adapter class that takes in an array of Locations and adds them to a ListView. This is all fine and dandy, but I would like to add Locations to this listview after this initialization. For example, someone can "add a Location" and it will add it to this ListView. Here is my Main Activity: package com.example.listviewtest; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ListView; public class MainActivity

问题 I'm currently using a ListView to display a sort of items. I've implemented an action mode to select multiple items and to delete massively that works well in android 4.x. But when I tried with API version 8 or 9 (android 2.2.x/2.3.x), selection works internally as expected but row items are colored randomly. If user selects first row, internally first row is selected, but row number 4 is colored. When I click another row, this row and first one is colored. It's a strange behaviour which I

问题 My Problem, is that I don't even know what to search for. I want a ListView. This ListView has some Elements with a "sticky" state. If I scroll down the List on the device, I want that all ListElements with state "sticky", to be sticky ontop of the list (non-scrollable) till there is another one "pushing it away". The rest of the elements are supposed to scroll as normal. I've seen that kind of List in the Google Market. If you have a big screen you can see that list on the Detailview of any

问题 In Honeycomb the Loader APIs were introduced as the proper way to provide data to an application by doing the heavy lifting on a background thread. In my application I'm working to replace all my Cursor s with Loader s that return Cursor s. Since Cursor.requery() is depreciated now, it is recommended to just call restartLoader and allow the work to again be done on a background thread and then changeCursor when it returns in onLoadFinished . All of this works wonderfully except that the
