simplecursoradapter

问题 I want to filter out some rows returned by a Cursor based on a specific condition (which I want to test after receiving the rows from the database, because it's not easy to add it to a WHERE clause in the SQL query). I found the following related questions: Filter rows from Cursor so they don't show up in ListView, Filtering a cursor the right way?, and How to hide specific rows of a Cursor in android. I want to implement exactly what those questions are asking. While the answers to those

问题 I was wondering how to set a number starting from 1 to n for my listview items. The column is not included in my sqllite database. I would like to use a custom simple cursor adapter that has a textview called labelNumber and set the number to 1 on the first call to newView and bindview and increment the value after each call. Is this the right approach or is there a better way. Obviously this is to help with the navigation of the list view to know your current position? Update- code is

问题 Please help. As I have stated in the title I am trying to make that individual elements of a row of a List adapter launch different actions depending on what the user click. It "kind of" works but it takes LONG for it to react to user clicks. What is it that I am doing wrong? Thanks in advance, So I tried the following code in @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); // Get the item that was clicked Cursor

问题 So I've got a ListView (using a ListActivity ) that I'm populating from a SQLiteDatabase . I'm trying to attach the ID (PK) of the row to the view, so that onListItemClick of each list item, I can do stuff with that ID. I've read that arbitrary data can be set to a View using setTag and retrieved with getTag (I haven't actually had this work successfully yet, so this may be the problem). Here's a pared down version of what I'm using (for simplicity/brevity): public class Favorites extends

问题 I have modified this example from the SDK pages to grab all the Contact Groups from the phone and display them. I cannot, however, figure out how to click one of them and then use the Groups._ID to do something else. Can someone teach me how to get a click/select listener on this list? MyListAdapter.java package com.example.simplelist; import android.app.ListActivity; import android.database.Cursor; import android.os.Bundle; import android.provider.Contacts.Groups; import android.widget

问题 My class extends SimpleCursorAdapter. In that class I try to get CallLog into ListView (with three TextViews (number, name and date) and two ImageViews (which represents incoming and outgoing calls). My code in OnCreate method: Cursor c = getContentResolver().query(android.provider.CallLog.Calls.CONTENT_URI, null, "TYPE IN (\"1\",\"2\")", null, "DATE DESC"); startManagingCursor(c); String[] from = new String[] {"number", "name" , "_ID" }; int[] to = new int[] {R.id.number, R.id.name, R.id

问题 I have looked through quite a few similar issues here on SO but none of which seem to solve mine. So I am trying to get a ListActivity to talk to SQLite using the SimpleCursorAdapter. I have run the code through the debugger and everything looks okay but my listView is empty. There is definately stuff in the DB and I have logged out what is in the cursor which has the right amount of columns at least. I'm fairly new to Android dev and I'm well aware that I might be missing something really

问题 I have made an application where i use a SimpleCursoradapter. String[] from = new String[] {"title","notes","image"}; int[] to = new int[] { R.id.esodaTextView, R.id.amountTextView, R.id.imageView1}; esodaAdapter = new SimpleCursorAdapter (this, R.layout.recipe_list_item, null, from, to); As you can see i show the three data at 2 TextViews (esodaTextView + amountTextView) and at one imageView. The question is how can i set a custom font (that is saved at assets folder) to these 2 TextViews

问题 Currently I am using code to give text suggestion. I would like to add another text and image. How do I do that? Currently, I am using the code below.I shows text but image is not displayed .How do I set the image ? public class AutoCompleteTextViewActivity extends Activity{ ImageLoader imageLoader; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder(
