Android :: Getting Checked Items From ListView Of Checkboxes

May 6, 2010

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.

Android :: Unwanted State Changes Of CheckBoxes In ListView

Apr 30, 2010

I am facing a very mysterious Problem. I am using a ListView with CheckBoxes that can be clicked to select people. The row layout is the following:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <CheckBox android:focusable="false" android:onClick="onSelectPerson" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_marginRight="5dip" android:layout_marginLeft="5dip"/> <TextView android:id="@+id/person_name" android:text="test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize="18dip" android:layout_marginLeft="5dip"/> </LinearLayout>

As long as the amount of rows doesen't exceed the screen size (-> no scrolling) everything works just fine. But as soon as I have more rows then the screen size (-> some rows are hidden and have to be scrolled to). I have a very mysterious phenomenon: If I check the top row and scroll down some of the previously hidden rows are randomly checked too. If I scroll up again, again some of the before hidden rows are randomly vhecked (the CheckBox I clicked in first place may or may not still be checked). Also the registered onSelectPerson callback is only called for the CheckBoxes I really click. The other CheckBoxes just change their state to "checked" without calling the callback method. I have the same phenomenom on the Archos IT 5 and the Nexus One. This must have something to do with the ListView implementation but I can't quite figure out what the problem is.

Android :: Checked In Text / ListView Not Working

Aug 14, 2010

I have a ListView that just contains a CheckedTextView. I have a very simple CursorAdapter that populates CheckedTextViews. When I click on an item, I can see that I am responding to the correct row, store the value in my model and the CheckedText gets checked. However, when I scroll down and then back up again, while I see that the model contains the correct value (in #bindView), calling #setChecked on the CheckedTextView has no effect. Ie All items are unchecked. Code...

Android :: Check A Particular Item In A Checked ListView?

I am using a ListView in which only one item can be checked at a time.

This is my custom list_row.xml :

When the list is displayed, I want to have, say the 5th item, in the list as Checked. How can I go about doing this? I know CheckedTextView has a function called setChecked(), but how can I get my 5th item from the list to apply this function on it?

Android :: Wrong Item Checked When Filtering ListView

Mar 21, 2010

The problem is that when I filter the list the entries switch position in the list view. Take for example three entries: 'A', 'B' and 'C' where 'C' is checked beforehand (i.e. the entry at position 3 in the list). When I type a 'C' on the keyboard, only the 'C' entry is displayed (as intended). Now 'C' is not checked anymore, since the entry has moved from the checked position 3 to the unchecked position 1 in the list.This behavior leads to some not very welcome effects in the app. Is there a way to "move the selection with the filtering", i.e. bind the checked state to the entry and not to its initial position in the list? Or do I need to find a new approach?

Android :: Setting Initially Checked CheckedTextViews In ListView For ChoiceMode - MultipleChoice

Aug 9, 2010

I am having a really difficult time trying to work with android's ListView multipleChoice mode. Here is what I am trying to do:

I have a "players" button in a game setup screen. When this is clicked it opens another activity with a multipleChoice ListView of all the players in the database in CheckedTextViews. I have this working properly and when you click on a player they will be added or removed from the game via a query to the game_players table.

The problem I am having is in setting up the ListView so that the players that have already been added to the game get checked initially when the activity opens.

I have tried to do this by iterating over the entire list in the ListView activity but this doesn't work because the Views that are not currently visible can't be accessed to check.

So now I'm trying to do this in my extended SimpleCursorAdapter in bindView but I can't even get this simple code to work:

CODE:.........

It correctly sets the player's name with setText(), but I can't get any of the boxes to check in bindView. Is there somewhere else I should be doing this or am I just doing it incorrectly?

Android :: ListView Checked State Wrongly Shared Between 2 Views When Reorienting Screen

Apr 25, 2009

I have TabActivity that uses 2 other ListActivities for the tabs. Both underlying ListViews are set to CHOICE_MODE_MULTIPLE. When I run the following sequence of events, I get a strange result: 1) Setup one activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 2) Reorient the screen (open the keyboard) 3) Setup the second activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 4) Switch back to the first tab

At this point, I can see in Eclipse that although (of course) each ListView is a distinct object, the internal variable used to store the checked state of items, called mCheckStates, is the SAME OBJECT REFERENCE in each of the ListViews.

Clearly this is an issue, since the two views should not share the checked state of items between them.

If I skip step #2, this does not occur

Here is a bit more detail:

After Step 1: ListView1 is object reference @1, ListView1.mCheckStates is object reference @2

After Step 2: ListView1 is object reference @3, ListView1.mCheckStates is object reference @4 (the reorientation recreates the views)

After Step 3: ListView2 is object reference @5, ListView1.mCheckStates is object reference @2 <-- note the reuse of this reference from step #1, not sure how/why

After Step 4: ListView1 is object reference @3 (unchanged), ListView1.mCheckStates is object reference @2 (changed) <-- same as ListView2.mCheckStates

Android :: ListView Items Not Responding To Tap

May 28, 2010

I'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"
android:orientation="vertical"
android:layout_width="fill_parent"............

Android :: Possible To Set Items In Listview Invisible?

Jul 20, 2010

I 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?

Android :: Controlling Width Of ListView Items

May 26, 2009

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?
