My app starts with a blank listview with a Menu option to Add contacts to the ListView. Now, I want that my ListView gets saved every time I quit my App so that the next time I start my App, I see all the contacts from last time. I understand that Android lets you store and retrieve data. Just don't know how to move forward from here.
View 2 Replies View RelatedI am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item.I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array?What is the best way to do this?

View 4 Replies View RelatedIn my app I have nice ExpandableListView. I would like sometime, depending of situation, to expand some or all groups. I would also like to be able to remove/hide groups, expand all and basically have (visually) ExpandableListView without groups. I looked at all available methods for ExpandableListView and couldn't find any that would do what I want to do.

View 4 Replies View RelatedI try to query contacts in a specific group by GroupMembership. But It only works fine with system built-in group "Starred in Android".
My codes is like this:
private static String[] GRP_PROJECTION = new String[] { GroupMembership.PERSON_ID, GroupMembership.GROUP_ID };
Cursor groupCursor = context.getContentResolver(). query(GroupMembership.CONTENT_URI, GRP_PROJECTION, "group_id=" + filterGroup_id, null, null);
Log.d(TAG, "number = "+ getCount());
If filterGroup_id is system built-in group id(Starred in Android), log.d() shows the number of contacts in group. But if filterGroup_id is my self-defined group id, log.d() shows the contacts of person in my defined group is always ZERO! Even there is actually some contacts in my defined group. Is this a bug for SDK1.5 R2?
I have A game to which I recently added a global high score functionality which made a lot of people upset so I want to add the option of disabling it.
What I did was this: in my settings activity view, I added the following code...
What I want to do is to disable the entire "High score specific settings" layout when the user unchecks the enable high score tracking check box.
I tried disabling it by setting the setEnabled to false, but that didnt work at all...
Should I be using a viewgroup or something?
Is there a refresh method I should run to apply the change?

View 1 Replies View RelatedI'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter.
The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost -> LinearLayout -> TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"

How to add items to a ListView in Android during runtime?
View 1 Replies View RelatedI have a listview that's using a custom adapter. I want to dynamically show/remove items from the listview. I've tried everything inside the getView() method in my view adapter. I've tried doing setVisiblity(View.GONE) on the view I'm returning. And it infact doesn't draw the view, but it allocates space for the view and it's just a blank black space.
Is this even possible to set items in listview invisible?
I seem to be having a problem with Android ListView. I'm trying to delete the selected item from ListView. The delete method is working and will allow me to delete as many items from my list as needed, but whenever I scroll to the bottom of the list (after atleast 1 item has been deleted) I get an Error that closes the Application.
Here is my code:
CODE:.............................
I have some class LoginActivity.java. In the onCreate method I retrieve ListView:
ListView list = (ListView)findViewById(R.id.snListView); then:
list.setAdapter(adapter);
In addition there are login.xml layout - there are:
<ListView
android:id="@+id/snListView"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
and sn_row.xml:

At the moment I have cell's height 100dp, I need that cell's height will depend on device, I mean I have here 5 cells showing at login screen in ListView and I need that these 5 rows will fit the ListView (cell's height = ListView's height/5).
Im using a custom listView with a Title and a Subtitle where you can read a brief explanation of the item.
For each item on the list, im displaying an alertDialog to select an option (different for each case). When the option is selected, i want to change the Subtitle for the option selected by the user.
This is what i tried:
CODE:.....................
For the first item on the list it works fine, when i select an option, the subtitle get replaced by that option, but when i make a selection in the alertDialogs of the other 2 items, the option selected replaces the subtitle of the first item!
After the listview is already initialized, is it possible to add items to it during runtime?
View 3 Replies View RelatedCan somebody please give me an example code of removing all ListView items and replacing with new items. I tried replacing the adapter items.Still no results.
My code is:
at first I am calling
populateList(){
results -populated arraylist with strings
ArrayAdapter<String> adapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, results);
listview.setAdapter(adapter);
adapter.notifyDataSetChanged();
listview.setOnItemClickListener(this);
}
I want to set the onclicklistner on the each item to be displayed in ListVIew. The code I have written is:
package munish.android;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class List extends ListActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Use an existing ListAdapter that will map an array
// of strings to TextViews
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, mStrings));
getListView().setTextFilterEnabled(true);
} private String[] mStrings = {
"ImageView", "Grid View", "List View", "Map View", "Image Switcher", "Queso Jalapeno", "Queso Majorero", };
I'm trying to make a list that contains elements not necessarily occupying the entire width of the screen, but even if using android:layout_width="wrap_content" on my elements, they always behave as if their width value were set to "fill_parent" instead. If I set a fixed value for the width, e.g. "100px", that value is indeed used, but I just can't get wrap_content to work.
Example simple list item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="#707"> <TextView android:id="@+id/text1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:layout_alignParentRight="true"
android:background="#770" android:text="Text1" /> <TextView android:id="@+id/text2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentLeft="true" android:layout_below="@id/ text1"
android:background="#077" android:text="Text2" /> </RelativeLayout>
What am I missing here? How do I accomplish a list item with wrap_content behaviour, i.e., where the width of each RelativeLayout is adapted to the length of the strings in the contained text views?
Given a listview that shows checkboxes next to a list of people, I want to be able to get the names (in Strings for example) of the people who are checked. I have set my listview mode to allow for multiple checks.
getCheckedItemPositions()
Will get the positions but I can't figure out how to iterate over the listview to get the names. Also Eclipse tells me that getCheckItemIds is not a valid method for ListView.
I have to drag and drop items of ListView, which typically have an image and text. How can I implement this.
