I'm trying to customize my buttons in my view a bit and give them my own look. Whenever I set a picture as a background so that the button looks different though, I seem to lose my cursor. I can use my trackball to go through the items still but when I come to one of my custom buttons the cursor does not show. I have the same problem with some TextViews that I made clickable.

I noticed the 4 big cursor keys on the side (landscape) and bottom (portrait) of the HTC Sense keyboard on the EVO. After playing with the HD2 that has the same layout, I prefer not having them there. It makes me have to reach farther with my right thumb to get to the spacebar and gives an unbalanced feel. I end up hitting the period by accident.
-Can the cursor keys be removed?
-If I install a 3rd party keyboard like Smart Keyboard or Better Keyboard (I've purchased both) on the EVO, will that get rid of the cursor keys?
The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.
View 10 Replies View RelatedI get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.
How do I merge these two informations?
I am looking after an alternative way now. As what I ideally want is:
Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure
Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList
Also this translated to TSQL it would look like
select * from contactsdata
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc
So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?
I have the android:cacheColorHint="#00000000" set on my ListView, which fixed this issue in one of my other lists in another activity, but it's not helping in this other list. I'm using the Light theme in my app, if that matters. I can't figure out what's going on. Long press brings up the context menu just fine, I just don't get the nice highlight of the row while pressing it.

View 4 Replies View RelatedI have a ListView set up in single-choice mode like this:
<ListView android:id="@id/android:list"android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#ff444444" android:layout_weight="1"
android:drawSelectorOnTop="false" android:choiceMode="singleChoice" android:scrollbars="vertical"
android:headerDividersEnabled="true"/>
When I press my finger on a choice, the selection changes from white text on light gray to black text on orange. But as soon as I lift my finger, the selection reverts to the original state. I'd like that chosen row to remain in the black-text-on-orange mode when I lift my finger so that the user knows what was selected in the list (my onClickListener has captured the selected row, of course). Is there a way I can tell the ListView that I want this behavior or something similar so the user knows what item has been selected?
I set setCursorVisible(false) on my EditText to get rid of the blinking cursor. Unfortunately, this also gets rid of highlighting. Why? How can I get rid of the cursor and not the highlighting?

I did find another article saying that I should set the selector to a transparent ColorDrawable, but the views in my GridView are still dimmed when I select them. I'm just using the GridView to display static objects (right now it's text, but I plan on switching it to simple images). None of these objects will be selected. Would it be better to just use a basic view and draw my images manually with quartz?
View 2 Replies View RelatedWhen viewing Web pages either in the built-in Web browser or in a WebView canvas, focusable items get the orange highlight ring as you navigate the page with the D-pad/trackball. A design team I am working with wishes to create some Web content, specifically for Android, where they handle their own focus highlighting via Javascript/CSS and wish to disable the built-in Android focus highlighting. In this case, the content is being viewed through a WebView, so I have some measure of control. I see some posts describing how to use ColorStateList, <selector>, and android:background to affect this sort of change, for a single View. How would one go about affecting this change for the contents of a WebView?

View 1 Replies View RelatedI have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?
How do I get the row ID from a Cursor?
View 2 Replies View RelatedI've got this piece of code where I count words in a dictionary and then I try to query them:
CODE:.............
The SELECT_BY_LENGTH is defined this way: private static final String SELECT_BY_LENGTH = "select word._id, word.word from word where length(word.word) between ? and ? ";
And the count works perfectly but the cursor.move(1) always returns false. I've tried to get the column count and responds with the correct count and the column names map too. I mean that the method getColumnIndex works too but I can't get any data from the cursor. All such methods fail. Am I doin' something wrong? I'm using android 1.5.
