Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.
Android has ListView component which is quite nice. The problem is that I created my own adapter to supply viewitems for each item displayed and I don't get anymore: Background color change when i scroll the items using up/down arrows. Background color change when I select an item. How do I do that?

View 10 Replies View RelatedI have an activity with a ListView check list and a spinner that controls the sort order of the items in that check list. One of the sort options is to move the checked items to the beginning of the list. I would like to allow users to check some items in the list, select the 'sort by checks' option, check some more items in the list, and select the 'sort by checks' option again. However, I don't see how to detect that second selection of the spinner's 'sort by checks' option.
I've tried using setOnItemSelectedListener, but it doesn't call the onItemSelected handler unless a different item is selected. And I've tried using setOnItemClickListener, but it seems that listener cannot be used with a spinner according to following run-time exception from logcat:
- - - D/AndroidRuntime( 987): Shutting down VM W/dalvikvm( 987): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime( 987): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 987): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.spinner/com.test.spinner.check_list}: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner.

Any tips on how to detect the selection of an already selected item in a spinner?

How can this be achieved?

I thought I knew how to catch list selection events in Android and then I regained consciousness. In my situation, I have a ListView that I populate with a custom view, all of the same class (let's call it the NewsChannel() class). NewsChannel consists of a LinearLayout of ImageViews and TextViews. When the list is displayed, the user may select a NewsChannel item in the list; I want to find out which list item was selected. Also, I registered an onClickListener to one of the TextViews and that works fine: when the text is clicked on, an activity is launched which is looking for the position of the NewsChannel item in the list. So, here's what my code looks like:
1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity {...
public void onCreate(Bundle icicle) { super.onCreate(icicle);
setContentView(R.layout.news_list_format); ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener()
{ public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text item_index = position;
Toast.makeText(getApplicationContext(), "item clicked = " + position,
Toast.LENGTH_SHORT).show(); }}); ...
2. The layout for the ListView associated with NewsListActivity:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/wpaper_tile" >
<ListView android:id="@id/android:list" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_alignParentTop="true"
android:dividerHeight="15dp" android:divider="@android:color/transparent"
android:cacheColorHint="@android:color/transparent" android:scrollbars="none" />
<FrameLayout android:layout_width="fill_parent" android:layout_height="55dp"
android:layout_centerHorizontal="true" android:layout_alignParentBottom="true"
android:background="#88000000"/>
<ImageView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true" android:src="@drawable/phonetop_bg" /> </RelativeLayout>
3. The NewsChannel layout:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:
android="http://schemas.android.com/apk/res/ android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<include layout="@layout/news_heading_format"
android:id="@+id/news_heading_header"/>
<ImageView android:id="@+id/news_channel_image" android:layout_width="88dp"
android:layout_height="66dp" android:layout_alignParentLeft="true"
android:layout_below="@id/news_heading_header" android:padding="10dp" />
<TextView android:id="@+id/news_channel_text" android:lines="4"
android:inputType="textMultiLine" android:layout_toRightOf="@id/news_channel_image"
android:layout_below="@id/news_heading_header" android:layout_width="fill_parent"
android:layout_height="wrap_content"/> </RelativeLayout>
When I run the app, the ItemClickListener is never called. However, if NewsChannel were of a simpler type, say, a single ImageView or TextView embedded in the layout, the callback does get called. Any idea what I'm doing wrong? My whole goal is simply to let the activity launched by NewsChannel (not shown) to find out which instance of NewsChannel it was launched from.
I have two questions:
1. How do you programmatically generate key strokes? I found some tutorials where it says to use IWindowManager, but that doesn't exist anymore in 1.5. (And WindowManager doesn't provide any function to generate key strokes)
2. How do you programmatically select one item from a ListView? Is it possible to do it with the index of the list item (it's position in the list)

I am to display the list and store the selected items in an array. But I am not able to get the correct items that were selected. Here whenever the user clicks an item, the array is getting updated, irrespective if the user is clicking the item to select it or deselect it. Could some one please help me solve this. I could actually perform an iteration to remove the odd numbered items in the array but I feel that would become an overload on the phone. Is there something for efficient. Please advise.

I am creating a group android SMS. Therefore, i need checkbox. But,my problem is i cant figure out how to get the selected contacts?

I kind of have a 2 part question here.
1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?
2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.
I'm displaying the contacts in a Multi-select "Ok, Cancel" dialog box. I've implemented Filterable for the adapter that displays the contacts in the dialog. The problem is, once i try and select(check) a contact while i'm using a type ahead, the check box in that particular position is checked and not the contact.
The initial screen goes like
After type-ahead,
When I hit backspace, the screen appears as,
This is my activity.

The adapter goes like,

I have a ListView. When I click on a ListItem, I set the background of the ListItem (it's view) to another color:

Here is my adapter:
CODE:......
The problem is, if I select multiple rows, then multiple rows have a colored background. I only want the clicked item to have a colored background. So if I click on row 2, I want it to turn red, then if I click row 1, I want row 2 to go back to normal, and row 1 to turn red.
I've been beating my head against the wall on this one for a minute now... did I find another bug like the list selector solid color one? When I set multichoice items for a dialog as seen below my list items have white background and white text, when I click or select an item I can see the text becomes black and the orange list selector shows as expected.... anyone know what's up?.............
