View 2 Replies View RelatedI have a ListView with an edit text and a button below it. When I click on a listView item the keyboard appears and push up the edit text and the button. I want the list to scroll to the selected item.
View 2 Replies View RelatedAn activity has a Button and a ListView. Initially, only the Button is visible. When the button is pressed, the ListView is displayed. When displayed, is it possible for me to show one particular item as selected/focussed?
A use case could be that suppose it is a list of language settings and when the list opens, the currently selected language must be shown as highlighted. If I know the index of the item, how to set it as focused on display?
I am an Android newbie trying to learn the UI side of things and it's doing my head in. Here's what I have right now:
CODE:.....
What I am struggling to figure out is how do I style the selected item? At the moment the selected item has a ghastly orange background which, under the rounded green rectangle, gives an orange outline effect.
I have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };
1) A ListView with many items (i.e. scrolling will occur at some point)
2) At the beginning, the selection is at the top (item #0)
3) User is scrolling down (i.e. we're not in touch mode)
4) For the first items, the selection is moving down without the list to scroll.
5) Once the selected item is reaching the middle of the list's viewport: the list starts to scroll-down.
6) Then, toward the end of the list: scrolling stops and the selection keeps moving down until the last item is reached.
It's a common feature in (keyboard-enabled) UI frameworks but I don't believe it's possible to achieve with Android, as for now... Right?
I have a ListActivity, and long-pressing on an item brings up a context menu. One item in the context menu is "delete", and that brings up a confirmation box (and AlertDialog). When the user presses OK in the confirmation dialog, I need to know the ID of the item that was originally selected, so that I can actually delete it.
The flow looks like this:
This event: Causes Android to call:
-----------------------------------------------------
Long press an item -> onCreateContextMenu()
Select context menu item -> onContextItemSelected()
call showDialog()-> onPrepareDialog()
user clicks OK -> onClick()
In onCreateContextMenu and onContextMenuSelected, I can get at the id of the selected item from the ContextMenuInfo. In onPrepareDialog, however, I no longer have access to that information. The rub is that onPrepareDialog needs this information to set up an onClick listener on its POSITIVE button.
I know that, during onContextMenuSelected, I can stash the selected item's ID away into a field of my activity. I have done that, and it works. But it's also really ugly. The statefulness that it introduces makes me uneasy. Has anybody else seen a better way to pass such information around than to use fields in the activity?
I have a listView of contacts that I got from the Android ContactManager sample. This list is showing up fine, but I can't figure out how to get info from the selected item, like "name" and "phone number".
I can get the selected position, but the result of the mContactList.getItemAtPosition(position) is a ContentResolver$CursorWrapperInner and that doesn't really make any sense to me. I can't get heads or tails from that.
Anyone know how I can get the name/id/phone number from the selected item in the listView?
Here is my code.

I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result.I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems.

I have an onListItemClick method in my ListActivity which captures and properly identifies the item selected in my ListView. What I am trying to do is change the text color or font of the item that is selected in the method, onListItemClick(ListView l, View v, int position, long id). Is there a way to access and change the text font and color using the ListView or View object from this method? I traversed the methods of each class and can't seem to find one that allows for that functionality.

View 1 Replies View RelatedI am a newbie coder and new to the SDK. I was just playing around with an app that i made. I wanted to know as to how to retrieve the item id of the selected item from the spinner when the spinner is re- populated.
For example, I created 2 spinners, if you selected item 0 from spinner1 then spinner2 will have a bunch of items and if you selected item 1 from spinner1 then spinner2 will have a different set of items. Now, my question is that when i select item 1 from spinner 1 then the items in spinner2 dont have different ids. So how do i differentiate from the two sets of data?
To illustrate,
User selected item 0 in spinner1 -> spinner2 gets data from array1 -> item 0 in spinner2 has id '0' and item text is "apple"
User selected item 1 in spinner1 -> spinner2 gets data from array2 -> item 0 in spinner2 has id '0' and item text is "oranges"
I know this sounds confusing but i hope the right people understood it..

View 2 Replies View RelatedI am creating a context menu in separate class from the listview, because the contextmenu will be access by several listviews in different classes. Whenever I long-click the listview, contextmenu pops up, but nothing happens when the options were chosen. Tried to look at logcat message and it said something like this:
Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@43c488f8
Any idea what really causing this problem? cause it works perfectly fine if i put the contextmenu on the same class as listview.

I 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.

I have a gallery that displays TextViews where the background of each view is the following code...
This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?
