I have some class LoginActivity.java. In the onCreate method I retrieve ListView:
ListView list = (ListView)findViewById(R.id.snListView); then:
In addition there are login.xml layout - there are:
<ListView android:id="@+id/snListView" android:layout_width="match_parent" android:layout_height="match_parent" > </ListView> and sn_row.xml:
At the moment I have cell's height 100dp, I need that cell's height will depend on device, I mean I have here 5 cells showing at login screen in ListView and I need that these 5 rows will fit the ListView (cell's height = ListView's height/5).
Is it possible to control the height of a ListView's header view(s)? If I try containing my header view in a layout and set the height to say, 50 or 100, the height in the view seems to stay around 30.
I have three ListView widgets in the same LinearLayout. Something like this (I'm omitting XML elements that are not relevant in this example):
This forces the list to have a height of 360 dip. Of course, that will be its height even if there are few list items. So, my question is how can make the lists have an automatic height? What I want is that the ListView height takes the exact size of the sum of all its list items.
I am loading a listview dynamically. I have set a .9.png image as row background image. The main purpose of using .9.png image was to extend the height of the image dynamically according to the contents of the listview. But, the image is not getting extended. The contents which can be displayed within the height of the row are being displayed and the rest are being cut.

When I use a RelativeLayout with either fill_parent or wrap_content as height and an element which specifies: android:layout_alignParentBottom="true" it is ignored and it is aligned at the top. Setting the height of the RelativeLayout to an explicit value makes it work.
How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"
layout_height="fill_parent" seems to not do anything if you put them in a scrollview
A working example of what I want is the email app compose window
I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough
I want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:
The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?
I am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:
What I should do to have the height of the RelativeLayout follow the full length of the gridView?

I've written an application which involves a lot of simultaneous connections to different servers. I've noticed some big stability issues with this as sometimes the program crashes totally (not just ANR, but a segfault type thing). What's the recommended number of maximum simultaneous connections for speed and stability?
If i have implemented a database in an application. So what ever the tables i create in that database will be saved in /data/data/packagename/databasess My question is how many tables i can create or how much data can i insert. How to know capacity of the database.In which factors will it depends.
I am implementing notification handler which logs any changes in content provider and it notifies Broadcast Receiver using custom Intent on periodic basis.But problem here is from Provider to Receiver all the values passed through Bundle.
I've installed Last.fm onto my desire for streamed music but I've noticed that it only plays 3-4 songs on average before stopping. the screen goes black which I guess means that it's going into sleep mode.
Currently I'm implementing a REST client which shall parse the XML response messages. It is intended, later, to be running on an Android device. Thus, memory and processing speed is quite an issue. However there will be only one XML response at a time so processing or holding multiple XML documents at a time is not an issue.
As fas as I understood there are three ways of parsing XML with the Android SDK:
SAX XmlPullParser DOM
Reading about these different parsing methods I got that SAX is recommended for large XML files as it won't hold the complete tree in memory like DOM.
However, I'm asking myself what is large in terms of kilobytes, megabytes, ...? Is there a practical size up to which it does not really matter whether using SAX or DOM?
I am going to install first application in my android phone, but having some doubts related to Android Memory (Maximum size of APK).
Help me know and solve the problems:
What is maximum size of the apk that can be supported by the android ? When we install any apk file in real phone, where does application installed (in SD-card or other memory) ??
I have referred this link: http://groups.google.com/group/android-developers/browse_thread/thread/7965885da4d1a03a and also searched lot.
I came Across the search on the web that many people are facing the same issue What is the maximum size of Application supported by Android. I think this question also help to the people who are connected with Android application programming and development.
This time i am having 58Mb application from that 52.5MB Images and it runs on the my HTC Hero mobile but On Emulator, it shows an error:

What is the maximum size that android application can hold? I have one database(.sqlite extension) file with 147 mb, Is it possible to include that file in my app.?I tried to put it in my asset folder but while running it showing message like "No space left on device".
There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.
