Is it possible for my android application to dynamically adjust the no of column and no of row of my TableLayout based on orientation?
For example, when in landscape mode, the TableLayout is 3x2 and when
in portrait mode, the TableLayout is 2x3?
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' making a remote-app, so i need a varying number of buttons, grouped by tableviews and tablerows.i can create the fix ones (that must alwasy be available) at designtime via xml, making use of the layouts making all buttons fit on every resolution.but there are buttons i have to create at runtime.to make them behave the same way as the fixed ones, i need to assign the layout width, -height and -weight values.i was searching the whole documentation, but there it's alwas done in xml, no word about runtime / matching routines.

View 1 Replies View RelatedI have a two column TableLayout as the only child of a scroll view. The first column contains TextViews ('labels') and the second column contains EditText/Spinner/DateWidget etc ('values').
Even though I have have specified android:layout_width="fill_parent" for TableLayout, TableRow & all widgets (in 'values' column).
The screen looks perfect when the activity is created. However, when one types a really long value in the EditText, the 'values' column goes beyond the visible screen area.
I have an android application that shows a grid view that shows:
1
2
3
4
GridView gridview=(GridView)findViewById(R.id.GridView_test);
DataBaseHelper dbhelper=new DataBaseHelper(this);
ArrayList<String> test=new ArrayList<String>(5);
backlinksadapter.add("1");
backlinksadapter.add("2");
backlinksadapter.add("3");
backlinksadapter.add("4");
ArrayAdapter mAdapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, test);
gridview.setAdapter(mAdapter);
By the moment is working, but i would like to show foreach line of the grid, 2 columns with the values of a 2 dimensional array (something like the GridView in ASP.Net - as datasource -).
I would like to show:
1 | Person 1
2 | Person 2
3 | Person 3
4 | Person 4
Any idea?
Can someone please provide me a ListView row layout that will show text on the left (the full width of the screen) and just leave one right aligned column for a count on the right? Everything I try has the text overwrite the count column...

How to add items to a ListView in Android during runtime?
View 1 Replies View RelatedI'm trying to make a list that contains elements not necessarily occupying the entire width of the screen, but even if using android:layout_width="wrap_content" on my elements, they always behave as if their width value were set to "fill_parent" instead. If I set a fixed value for the width, e.g. "100px", that value is indeed used, but I just can't get wrap_content to work.
Example simple list item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="#707"> <TextView android:id="@+id/text1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:layout_alignParentRight="true"
android:background="#770" android:text="Text1" /> <TextView android:id="@+id/text2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentLeft="true" android:layout_below="@id/ text1"
android:background="#077" android:text="Text2" /> </RelativeLayout>
What am I missing here? How do I accomplish a list item with wrap_content behaviour, i.e., where the width of each RelativeLayout is adapted to the length of the strings in the contained text views?
I currently have a ListView being filled by a custom Adapter with content it gets from a JSON string on a web page. The ListView's row layout is a LinearLayout that has two things in it, one AdMob layout and one TextView. The AdMob layout's visibility is by default set to Gone.What I want to do make every 5th row's AdMob layout visible. The current way I am doing this is by Overriding getView in my custom adapter (something I already had programmer to get my rows to have alternating colours), within this I keep track of the position variable and see if I have moved down 5 rows yet. When I have I find the AdView object and set it to visible. This works fine for a while but for some reason as I scroll down more on my list the ads become every other instead of every five. This doesn't make any sense to me because I have set up logcat to tell me when it reaches my "make ad visible code" and according to that I should not be having double ads. Has this happened to anyone else before? I'm not quite sure how to handle this situation.

I am new to android development and have been tasked with developing an app. One of the screens will require there to be a list of people with some thumbnail information about them, similar to:
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
[code]....
This information will be stored in an SQLite DB. Now I can see that listView seems only to work with a single column. What is the best way to go about this?

View 2 Replies View Related1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.
However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)
I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".
Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?
2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:
I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...
I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

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?

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.
