Android :: Make TweetDeck Droid App Like Column View?
Aug 21, 2010
The add/remove columns UI of TweetDeck android app is very promising. But I have no idea how to make one like that.
If I make it with HorizontalScrollView, and the children with layout_width set to "fill_parent" code...
I can't scroll horizontally and only see one view.
If I set the layout_width with number like this: layout_width="320sp" then the two columns sit next to each other and I can scroll horizontally.
Do you have any idea how TweetDeck makes theirs?

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).

What I want is a central column using Grid View, but everything I try does not work. It always aligns to the left. I have tried messing around with layout_gravity and gravity to no avail. I have a Grid View in a Linear Layout:
<Linear Layout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent".

This has got me all confused! I'm trying to return the max value from a column in my database but the return value is always the name of the column.
The query I use:
private static final String SELECTMAX = "SELECT MAX(?) FROM " + TABLE_NAME ;
The (test) function to return the max value:
CODE:............
The column i'm querying is an INTEGER type but the result 's' is always the column name and not the desired value.

I have an XML layout with some custom tabs, a heading, and a ProgressBar(main.xml). I wish to add another XML layout(home.xml) to the main.xml layout, as i wish to keep main.xml re-usable for other activity's layouts and simply add things to it as necessary.The problem: after inflating R.layout.home into rootLayout, it seems as though the ProgressBar contained in rootLayout is hidden underneath the content of home.xml.Is there a way to tell certain views(via XML) to float above other views when the layout is constructed in this way?if not, am i forced to use methods such as progressBar.bringToFront() to raise targeted views to the top?what alternatives do i have in z-ordering views when some layouts are constructed using inflation?

I 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 am making an android application that shows a list with users, I would like to add the image,name,status,and a button in every row of the list, just like in the androids 1.6 native caller-> favorites tab.Until know I have managed to add the image and name using an ListActivity but when I try to add the button the list becomes unselected.So I have 2 questions, first is the list mentioned above listviews or listactivities? also is this possible using listActivity? and second, what is the difference of the above mentioned classes?

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?

How can you specify a column span in an android's gridview?
I have a gridview that displays 3 images for each row. Sometimes, there are images that have to span 2 rows.
Is it possible to do that in Android?
or should I be using a different view?

So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function.
Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution.

I have a GridView of 9 rows of which the first one is sort of "header" row.As there are 8 more rows they flow beyond the end of screen and need to be scrolled down to.However this scrolling also causes the first row to go "off-screen".Was wondering if there is any way I can prevent the first row alone from being scrolled off?I dont want to make this a separate LinearLayout as it is part of a dynamic View (the GridView) that I create at runtime.

My app, among other things, downloads and displays images from the Internet. Some might be too large and trigge an OOM when ImageView.setImage() is called. Of course, this normally makes the application to crash. I've put catch (OutOfMemoryError e) around the method invocation. I know that catching errors is unusual, but in JSE applications it proved to work pretty good, especially when the problem was due to image manipulation that consumed all the memory. The Android app seemed to survive for a while, but then it blocked the computer. All buttons are irresponsive, even though the phone seems still alive (e.g. it's playing the audio notification that new email has been spotted). I tried holding the power button, it triggered the shut down menu, but touching a menu option didn't do anything. Only after a while, the phone became responsive again.
Now, it's reasonable that one can't display everything on a smartphone; I'm sure there's some inefficient memory management I'm doing (perhaps keeping too many images in memory); ok, I have to improve my code. Given that I'll do, how can I add some safety facility to avoid the most severe consequences? Making an irresponsive application it's a 100% sure way to make people to uninstall my app and give bad reviews. I'm thinking of a two-pronged safety approach: 1) whether it's possible to understand in advance whether an image is too large to be rendered by itself;
2) whether it's possible to recover from an OOM in any case.

I'm attempting to create a method that will allow me to retrieve a value from the last row of a database, and then insert it into an EditText field. (This is a value that the user will not change all that often, so it would be helpful if when they do set it, it stays set when they come back to it).
My method, based on a similar method I have for getting the total of a specific column, is as such. code...
If I run the program without this statement, it works fine and the value saves to the db. As soon as I try to run it with this, I get a force close. Any suggestions?
