I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

I have been getting opinions that I should have gone for table layout could someone please save me from doing the work from scratch. I really dont want to do everything again. Thanks and sorry for the posts. Trust me this problem is different than last one.
I would like to have my list activity to display 2 items(title, content) in a single row. I have almost 10 rows to display like that. And I want the width of the columns to be equally spread out. I tried with linear layout and table layout, but I could not bring the columns equally sized. I am using the following layout. kindly help me and advice me on this....

I have a simple grid with rows of items and columns of options on each item. Of course I can manually link OnClick actions to cell items through specific resource IDs:

What I'd prefer to to is use a ListView or a GridView and an Adapter. Is there a way to get cell id's from one of those? I was hoping that ListView setOnItemClickListener() would call me with the view id of a view within row 'position': onItemClick(AdapterView parent, View view, int position, long id) { ... }
But no go. Maybe a different approach?
Update:
I started with this:

I'd assumed that I couldn't go into my Adapter and set child view OnClickListeners. Bad assumption. When I went back at this I gave it a try:

How to align an image button bottom right. My code is as follows:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center_horizontal" android:background="@drawable/help"
Seeking help to design a layout as shown here:
http://docs.google.com/Doc?docid=0AQhgDtGvE2HgZGZ6cmtua185MTd0eGdyZmc&hl=en
The major challenge I face is aligning the components at desired positions. Please refer the three buttons(icons) and the way they are positioned.
Literally, going nuts, thinking how to position those exactly at the desired places.
Im messing with imageviews and I am able to align a single imageview in the center horizontally with android:layout_centerHorizontal="true"
Now my main problem is that I have X imageviews and when I align them all like that, and then use the android:layout_toRightOf="", they just start from the middle.
Why doesn't the following code align with the center?

I'm just about ready to Publish my application. I have a question about the Signing/Aligning of the application. In looking at the Android documentation they say to run "ant release" to compile the application in release mode. Then to sign and align the apk run "jarsigner" and "zipalign". I had used "android create project" to create my build.xml.
I modified it to run proguard. I find that when I run "ant release" it appears that signing is done as part of the process (I'm prompted for my keystore password) and the apk is zipaligned. I guess I'm confused that the documentation makes it 3 steps, "run ant release" then jarsign, then zipalign. BUT, my "ant release" seems to do everything. Is the documentation not upto date? Is it safe/acceptable to just run "ant release"?
I am having a problem in ScrollView. When i run my application on X10i it works fine but when i change the view to landscape half of the layout at the bottom (RelativeLayout) go down to the screen. Here is my Layout code. please suggest a general solution that will be applicable to all phones not only X10i. code...
View 2 Replies View RelatedIs it true that if you have a ViewGroup, say a RadioGroup, you can't align items outside the group to ones inside the group (using toRightOf, alignTop, etc.) That is, does toRightOf, toLeftOf and the rest only work with views at the same hierarchy level? I was trying to label some vertical radio buttons today and find I can only align to the RadioGroup and not the buttons inside the group.
If I remove the RadioGroup, then I can align things OK. There are lots of workarounds, of course, so I'm not stuck. Just thought I'd ask and document. And, BTW, where is the hot sh*t resource editor for Android so I can bang out screens quickly like the iphone guys, using a visual interface designer that knows all these silly interactions? The tools I've seen so far have been toys.
I am using relative layout to superimpose one smaller image on top of a larger one. I want the bottom-right corner of the smaller image to coincide with B-R corner of the larger image. Im using margin parameters in my layout xml (specifying measurement in dips) but this doesnt seem to work for all devices and resolutions - in some cases the small image is shifted by 4-5px from the border. Is it possible to specify the position of the smaller image without pixel values? Ie with gravity or something?

I want to design a table whose first column items remain fixed when user scrolls horizontally, but should scroll when the user scrolls vertically. Similarly the first row items remain fixed when user scrolls vertically, but should scroll when the user scrolls horizontally. Can this be achieved using a TableLayout? Or is there any other combination of widgets that I could use?
View 2 Replies View RelatedOne of my android apps performs the following specific SQLite query:
CODE:................
Now that works on some Android phones, but on a few of them it crashes with the following error:
CODE:..................
For some reason, "-1" is interpreted as a column rather than a number... that doesn't make much sense and when I read the SQLite query language I see no need to escape this number in parentheses. Could it be an issue of a different version of SQLite? Would adding parentheses this help any? Instead, I'll probably rewrite it using >= 0 but still I'd like to understand what's going on.
I'm having trouble with something that works in the Notepad example.
Here's the code from the NotepadCodeLab/Notepadv1Solution:
CODE:.................
This code seems to work fine. But just to be clear, I ran the adb utility and run sqlite3 I inspected the schema as follows:
CODE:...............
All seems good to me.
Now on to My App, which as far as I can see is basically the same with a few minor changes. I've simplified and simplified my code, but the problem persists.
CODE:..............
When I run my app, I get a RuntimeException and the following prints in LogCat from my Log.e() statement:
LogCat Message: java.lang.IllegalArgumentException: column '_id' does not exist
So, back to sqlite3 to see what's different about my schema:
CODE:.................
I don't see how I'm missing the '_id'.
Can anyone point out what I've done wrong?
One thing that's different between my app and the Notepad example is that I started by creating my application from scratch using the Eclipse wizard while the sample app comes already put together. Is
there some sort of environmental change I need to make for a new app to use a sqlite database?
I'm not big into UI programming so this may be an easy thing I overlooked. I am trying have a screen that shows 8 TextView in a 2 column x 4 row table. And, of course, I want the TextViews, that might have different lengths, to be centered. I tried this in a table layout, for obvious reasons but I feel like this is not the way to do it because it doesn't have much control where I put everything once it is in a row. Should I be using a different combinations of layouts or is there something I overlooked.

View 2 Replies View RelatedCan I add a column of data to the Contacts db, such as birthday, favorite color, whatever. Or does the platform/ framework make this difficult? If possible, would I do it through the contacts content provider?
View 4 Replies View RelatedI read that the different entries in different tables are linked via the _ID column in that table. For example a contact might have an _ID = 1 I get via
ContactsContract.Contacts._ID
And now I want to read the phone number of that contact using
CODE:.............
This works fine, but what I would expect is that if the _ID of the contact is 1 that the _ID of the phone number is as well one since they belong together, but they are not equal. So the question is how does Android match these entries?
This is an incredibly dumb question. So, apologies. But I can't find the answer anywhere and it's driving me nuts.
In DDMS, I have lost the tag column, i.e. the first part of the message from Log.d(tag, message). I can see time, log type, process id, and message - but not tag!
Anyone know how to get it back? I've tried right-clicking the columns, looking through the menus, etc - no joy.
