I can not find the ListView, But When I chang the LinearLayout to TableLayout, the ListView show up.
I use the following main.xml for my app.

I want to have 2 buttons at the top, previous and next and my listview with custom adapter below it. Few days ago I had only my ListView showing, going over the buttons. Now I seem to be stuck on the other side, where my listview doesn't show while my buttons do.
My activity extends on ListActivity and uses this code to fill it with a customadapter.

I tried using "lv.addHeaderView(previous);" but that only gave me vague ClassCastExceptions about LayoutParams.
I think my problem is currently in my main.xml, as the Layout tab in Eclipse of it won't show the ListView either. It knows its there as it shows up in the outline tab, but the visual representation doesn't give it a red outline when I select it.
For completeness, my custom_list (aka row) layout xml:

I have an issues, I want to show 20 items in the list.
But there is a catch: if the user scrolls down to the bottom of the list, there will be an item that says: "Show more items", and when the users click on it, more items will be added to the list.
My question is how is poosible to have a last item, that has a different style and looks different: and does different things,(I think this is used in QuickSearchbox)
Here is my Arrival.Java. May i know why isn't there any data being shown on my ListView?

View 1 Replies View RelatedI have a listview of items (songs on the sd card). The user has an option to load all the songs on the sd card to into a current playlist -- those songs are what is displayed in the listview. Because this can take few seconds to load if they have a lot of songs on the card, I want to display a progress dialog to just tell the user "One moment..." until the list refresh is done.
I launch a thread to do this. I've done this successfully on another app I have (which just updates a database in the background but doesn't update any display), but this one fails with this error message, "Can't create handler inside thread that has not called Looper.prepare()". I chopped down the activity and pasted it below. What am I doing wrong here? I have just a vague idea of what might be happening.
By the way, everything works when I take out the threaded stuff, it just looks like the app freezes for a couple seconds.

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?
How can i set the number of items to show in a list without to scroll?
Example: I have a list with 10 items.
I want that only 3 items appears and that I have to scroll to see the rest of the items.
I'm developing an Android application.Is there any way to show a message on a ListView only with it's empty?I'm using a custom ArrayAdapter, so I have to create a specific object with the text I want to show.I'm wondering if there is a specific field on ListView to setup a message when it's empty.

View 3 Replies View RelatedI have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.
View 2 Replies View RelatedI use this code in my getView:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listrow, null);
}
Order o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
ImageView thumb = (ImageView) v.findViewById(R.id.icon);
if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());
}
}
return v;}
The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.
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 populate a ListView from the result of a Sqlite query; one of the fields is the image file name that i would like to show as image into a listview.
How can i do to show the image file?
I use
SimpleCursorAdapter(this, R.layout.list_name,cur,new String[] {"fields_list"}, new int[] { R.id.list...});

I realize there's hundreds of ways, but a clean and simple example would be appreciated.
Currently I have a list view within it each row has a checkbox attached. I would like that once any checkbox is checked, at the bottom of the screen a view displays, and once none of the checkboxes are checked, the view automatically disappeared. Possible to do this?

I have a SQLite database with two tables- BOOK and AUTHOR. I execute a query on the DB that uses a join and results in a cursor that looks like this. code...
New authors and books can be added to the database at any time, and I also need the user to be able to remove books, hence the [ ] checkboxes.
So i have two row layouts, row_author.xml & row_book.xml. I detect when I need to show a row_author subheading by seeing when the current author has changed compared to the previous row. But I have realized that the rendering of an Author Row will then move the cursor forward one row and jump over their first book.
Can anyone suggest a good approach to presenting data like this? Is there a much better way to do this?
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.
I have a problem with ListView, it seems a bug, setting a textsize for textview of a ListView, not all separator line are shown! (ListView doesn't show all item separator)...

I have prepared a little testcase for this issue: [url]
I have written a ListView with a text and image clubbed together in a row. I wanted to add a button on top of listview, then the entire content of listview should be seen. Button is named as "More", when someone clicks it i will be updating the listcontent. That is the main theme.
My java file.
CODE:.....
* Demonstrates how to write an efficient list adapter. The adapter used in this example binds
* to an ImageView and to a TextView for each row in the list.
*
* To work efficiently the adapter implemented here uses two techniques:
* - It reuses the convertView passed to getView() to avoid inflating View when it is not necessary
* - It uses the ViewHolder pattern to avoid calling findViewById() when it is not necessary
*
* The ViewHolder pattern consists in storing a data structure in the tag of the view returned by
* getView(). This data structures contains references to the views we want to bind data to, thus
* avoiding calls to findViewById() every time getView() is invoked.

I have a problem that some other people on this list (and other android sites) also have/had, but was unable to find a solution. I have a ListView with a custom view for the row which looks like this: <RelativeLayout><ToggleButton/><TextView/></RelativeLayout>
Its basically a list of songs that i show. What i want to achieve:
If the user clicks on the ToggleButton the song should be played. If the user clicks somewhere else on the row, the details intent of the song should be launched.
So I want to have two events on every row, event1: the button click, event2: click somewhere except on the button.
Right now i have a custom adapter where i call .setOnClickListener() on the button. Now the button works (event1 works), the song is played, but the rest of the row is not clickable (event2 does not work). If i remove the call to setOnClickListener() the row is clickable (event1 works) and the details are displayed as suppossed, but the button is not working. (event1 does not work)
There are apps out there, that have buttons in lists so this must be possible. Could someone please tell me how to have more than one click event on a lists row?
I am new to android. I would like to add two normal buttons in the List (ListView).
Could you please provide me any example of source code so that i can understand.
I have Button and TextView in my ListView , and I would add listener on button but I can't do it.
Actually I have in my adapter :
CODE:.........
The OnClick works but, I would like to display alerts on my activity and I can't do it :/ I don't know how to lie my activity and my adapter.
How can i set the button to show a different image after it's been tapped? Either a different image, or maybe some kind of highlighting that shows the button was tapped.

The ListView in each item is GONE by default and is set to VISIBLE when the button is clicked. Everything seems to work fine with the exception that when the ListView is long enough to scroll, it is just kind of truncated. http://img38.imageshack.us/img38/3269/listviewproblem.png
Is this a problem with the maximum height of an individual list item? Is there a way to force the list item to expand and force the child listview to expand to show all children?

View 2 Replies View RelatedI am trying to bind a list view to a List. This works ok when I create an activity that extends ListActivity and I have a text view in my layout file (i.e. the activity is binding to the default listview in the activity). However, what I would like to do is have a ListView that contains an image button (to further perform the deeltion of the row) and the text view to illustrate the name of the item being bound.
The layout file
The activity class
I have played around and cant seem to get it to work, as soon as I add a ListView / image button to the layout file my code crashes. I've also found a few examples through google, but none seem to work!
