Android :: ListView Items Won't Show Focus When Touched
Jun 20, 2010
I've got a ListView that works just great, except for this minor annoyance. I can use the trackball/dpad to move up and down my list, and the background changes according to which row has focus. But when I touch the row (click or long click), there's no background change letting me know what's been focused. I've tried setting 'focusable' and 'focusable in touch mode' to true on the rows, but it still doesn't work.
Just in case it matters somehow:
I am setting onClickListeners for each row. The row is comprised of LinearLayouts, TextViews, and a single ImageView. Focusable/clickable is 'true' for each row. Have not specified values for these on the ListView.
Trackable does act funny. I can only move between rows after touching inside the ListView. If I scroll trackball above the first item, it's impossible for me to scroll back into the list.

I'm building a list that is sorted alphabetically. The list should show a divider containing the Letter that the following icons belong to.
I'm using a Cursoradapter that contains the already sorted result from the database. I plan on adding the divider to the list item and set it to visible if the shown letter changes. How do I know that I have a new Letter? Is there a better way then going forward or backward in the cursor and check if the item I show is the end or beginning of a new group?

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.
However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).
1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.
2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?
3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

The context: I want to have a ListView that wouldn't receive focus (e.g. won't highlight row when user touches it). Yet each row widget has it's own OnClickListener.
Here's what I specify in layout xml:

I am trying to apply a selector to a ListView to make it easy for those without touch screens to navigate my app. The thing is, by applying the selector to the ListView, it only seems to apply the background colors to the entire list, not the items inside of it. Code...

I have an activity with ListView and buttons below:
CODE:.................
ListView row contains delete button:
CODE:.................
In Adapter, Button onClickListener is set, also there are dummies to make list non-selectable:
CODE:..............
What I want is:
Always show buttons in the bottom of screen after list (no matter how long it is, there should be scroll if it's too long) ListView should not be selectable, I don't want row selection row delete button should be selectable (focusable) with touch and with trackball
And everything works except I can't focus row delete button with trackball (although it's working with touch).

A few days ago I was trying to fix this issue: I have a header (three ImageButton's) and a ListView. If I use the dpad, pressing DOWN to focus the ListView, the ListView shows as selected the seventh or eighth row, not the first one.
What I need to do is that the first element of the ListView get the focus (or selection) when I use the dpad, from another screen component, but instead, the seventh or eighth is selected.
I had minSdkVersion=3 in my manifest. When I changed it to minSdkVersion=4 it worked as expected (first row selected). Don't know why, but there is a difference between both.

I've set the row (view) being used in a ListView as non-focusable along with non-clickable and have set the listview's focusable flag to false as well. However, I still get the yellow highlight when I use the scroll-ball on my device. How can I disable the yellow highlight and use my own special view/color instead upon focus?

I'm showing an input box using AlertDialog. The EditText inside the dialog itself is automatically focused when I call AlertDialog.show(), but the soft keyboard is not automatically shown. How do I make the soft keyboard automatically show when the dialog is shown? (and there is no physical/hardware keyboard). Similar to how when I press the Search button to invoke the global search, the soft keyboard is automatically shown.

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"............

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?

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:

I have some EditViews in the rows of a ListView.This works just fine except when the soft keyboard raises and lowers.When I touch the EditView within the ListView with the soft keyboard down, focus jumps to the EditView, then the keyboard comes up, removes focus from the EditView and sets focus to the ListView, resulting in an odd user experience with the focus no-where visible.Touching the EditViews with the keyboard already showing works as you would expect.The problem seems to be with the soft keyboard lowering and raising and the ListView getting confused about where focus should be placed.
