android-listview

问题 Im very new in android programming, and my task is to load up the items in my shared preference to a listview, and i just want to change the design of my listview, like changing its font color, font size and etc.. I have tried this solution but it doesn't work, please tell me where I did wrong. Thanks.. heres my code in loading the listview in a listactivity Map<String,?> datakeys = datapref.getAll(); for(Map.Entry<String,?> entry : datakeys.entrySet()){ Log.d("values123",entry.getKey() + ":

问题 i implemented Custom cursor adapter in my listview. but the listview is always null. Let me explain my codes: OfflineAdapter offlineadapter = new OfflineAdapter(ctx, null); listview.setAdapter(offlineadapter); There's nothing really to explain Here. Moving into my offlineadapter Class: public class OfflineAdapter extends CursorAdapter { public com.androidarabia.lazylist.ImageLoader imageLoader; @SuppressWarnings("deprecation") public OfflineAdapter(Context context, Cursor c) { super(context,

问题 I've been Googling like crazy for a while now, and I simply can't find any answers to the question: is it possible to implement the Android List scrolling, without using an actual list UI? I'm trying to make a grid of rectangles such as the kind you would find in a typical game app respond to finger movement in the same way that it does using Android lists (bounce on the bounds, the 'flick' effect, etc), but all of the approaches I've found involve over-complicated solutions involving

问题 I am designing a Gridview that has a TextView and ImageView inside each Item. I tried to find tutorials (updated and clear step by step ones) on how to make the ImageView clickable as well as the GridView Item itself (both would trigger different methods()). This is what I have so far: Activity.java String[] newList; for(int i=0; i < 6; i++ { newList[i] = "Item" + i; } GridView GV = (GridView) getActivity().findViewById(R.id.sexp_fav); GV.setAdapter(new GVAdapter(getActivity(), newList)); //

问题 I have another blocker as I study Android Development. This time my problem is when I wanted to "selectively" highlight a row in a ListView populated by data from an adapter. This ListView is actually within a dialog, and purpose is to show a list of friends, where user can multi-select and highlight it as he selects. The selected values by the way, is stored in an ArrayList "arr_FriendsShare" so that the next time he opens the listview, rows will be highlighted (via onScrollListener) for

问题 I've an app that is retrieving a date that is stored as a string as a millisecs from 1970, eg 1324657734883 . I have a ListView that displays this date asis. I'd like to display the joda DateTime from this field in the database. My view displays the listview and populates it by using startManagingCursor() so i don't think there is any way of converting the milisec format to a DateTime before it is populated to the listview . Is there a way around this or do i have to store a DateTime and if

问题 Not exactly sure what is going on here so I am hoping one of you can point me in the right direction. I have a ListView within a Tab frame and for some reason, it loads but crashes when I try to scroll. Here is all of the information I could gather Here is the Activity that goes into the frame... it parses an XML file into a priority queue, gets the attached intent information, and loads the desired page. public class QScoresFrameActivity extends ListActivity { private PriorityQueue<Score>

问题 You can see I have three cases on the MainActivty.java which is pointing on the same activity Ekantipur.java but in Ekantipur.java I have only one link. So when you click any of the three listview it will open the same links. So I want to open different links when you click on different listview items when different position in listview is clicked. I donot want to make different activity for that. This is just with three cases but I have around 20 links and I donot want to make 20 acitvity

问题 I am trying to build something similar to the Android Fragments tutorial: I have a ListView fragment on the left and a fragment that can display an item on the right. Now I am trying to auto-select the first item in the list as soon (or soon after) it has been loaded through the SimpleCursorAdapter (which I use through the LoaderManager)-- all using the Android support library. public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); mAdapter =

问题 I've tried several methods of deleting the record from a listview on item long click but, nothing happens, no errors, no delete nothing, just the toast shows up... Here is the code: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); overridePendingTransition(R.layout.push_left_in, R.layout.push_left_out); setContentView(R.layout.moje_ure); getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); datasource = new VnosiDataSource(this
