I have a listview in which there should be different divider height between different rows. So, how can we set the divider height dynamically?
Suppose, I have 10 rows and there should be a divider height of 5 between first 2 rows and then there should be a divider height of 1 between next 5 rows and so on.

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.

I want when a user clicks a row, that row grows to show more items with an scale animation, but I can't find how can I do that.
First: I don't know how can I change a height row at runtime. I've tried making the items visible, but this didn't work even if I inflate with another XML layout.
Second: If I achieve the first one, I think I could make the scale animation.

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).
I have three ListView widgets in the same LinearLayout. Something like this (I'm omitting XML elements that are not relevant in this example):
CODE:..............
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.
Im using a custom listView with a Title and a Subtitle where you can read a brief explanation of the item.
For each item on the list, im displaying an alertDialog to select an option (different for each case). When the option is selected, i want to change the Subtitle for the option selected by the user.
This is what i tried:
CODE:.....................
For the first item on the list it works fine, when i select an option, the subtitle get replaced by that option, but when i make a selection in the alertDialogs of the other 2 items, the option selected replaces the subtitle of the first item!
I wanted to change the divider height dynamically. From whatever I have searched it seems that it is possible through setting divider as part of each item in listview. But I am not very clear with this. So, can someone be more specific as how can one make the divider as part of item in listview?
View 3 Replies View RelatedI can't seem to get a customized divider, using a Drawable I've defined, to work when using a ListActivity and not creating a custom ListView. It almost seems like when the VM creates its own ListView for me, with the ListActivity, it uses a theme with the default divider provided; and if I try to provide one, no dividers appear in the ListView at all.
I know that I can create a custom ListView using XML and define android:divider on that ListView, and this does recognize my custom divider Drawable. But I would prefer to just let the ListActivity create its own ListView, if I can figure out how to get my own divider working on it.
Here's the code I'm using now:

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.
Can I modify android.R.layout.simple_list_item_1? For eg., I want to change the text color of the textview inside the listview dynamically. For this, I need to get to the textview and change its color.. How can I do that?

I want to simply set the height of an EditText component to be 50% of the user's screen height.
I'm creating the initial layout from an xml file (main.xml), loaded in the Activity's onCreate(Bundle). From the xml configuration, I understand how to set the EditText height to a literal value, e.g., android:layout_height="150dip", and from the onCreate(Bundle), I understand that I can call setHeight(int) on the EditText component, but the call to setHeight(int) appears to be ignored, and if I don't have the layout_height setting out of the xml, then I get an exception when my app is starting, complaining that the height value is required (and the app dies).
Is there a way to set the height from the xml based on the user's screen height? In other words, within the xml, is it possible to retrieve the user's screen height and use it to calculate a value for a component?
(I'm placing the EditText in a LinearLayout with vertical orientation.)

View 1 Replies View RelatedI have an ExpandableListView (ELV) with the groups having LinearLayout. I have set the height of the group to some value (38dip in this case, equivalent to two lines of text). If the group heading is long and would take more than 2 lines, it is not shown properly in the ELV item - some part of the view gets scrolled. On the other hand, if I change android:layout_height to "wrap_content" in the LinearLayout, the groups always show all the lines. But the line widths are variable, i.e., short titles show up with only 1 line and long titles show up with 2, 3 or 4 lines. That looks ugly. I would like to implement the height to be something like max("38dip", "wrap_content"). Is there a way to do this?
Even programmatically, I do not seem to be getting the actual height of the group if I set android:layout_height to "wrap_content". Any suggestions there?
