Android :: OnClick() Event On An Item Of ListView Custom Row Layout
Nov 15, 2010I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.
Now, I would want something like this-
User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks)
I get to know the position of the row whose ImageView was clicked.
I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill).
Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.
I have provided an attribute in the Row XML like this-
CODE:..................
And in my code, I have a method like this:
CODE:..............
I can get the parent row (perhaps) but am not sure how to go further from here.
Deleting Item From ListView Layout And SharedPreferences
Sep 14, 2013How to delete an item from a ListView.
I have a layout which includes the listview, an edittext and a button. On button click, the edittext's string is added to the listview. Clicking on a listview item opens a dialog which asks for confirmation to delete that item. When confirmation is received, the item appears to delete. But when the delete button is clicked on another item, the item deletes, but the previous item reappears in its spot. From my limited understanding, I assume that the item doesn't delete from the SharedPreferences, and so when they are loaded again, the item reappears. I've tried clearing the SharedPreferences before saving after delete, but this didn't work (though I could've been doing it wrong).
I've included the whole class incase to test it out in IDE. I understand there are a lot of unneeded objects and the code is quite messy which is a result of me screwing around with the code to try and get this to work. Though everything works as it should, aside from deletion.

Android :: Cannot Display Image Correctly Using Custom Item Layout In ListView
Apr 22, 2010I am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.
This is the item layout I made (post_item.xml):
CODE:........................
I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.
I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).
When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).
I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.
Here is my code for the Adapter:
CODE:..............
And this is the code to prepare the items:
CODE:.........................
Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?

Feb 20, 2010This seems like a simple problem to me, but I can't figure it out. I have a fullscreen layout that displays differently if the screen is taller (854 instead of 800 pixels). I've tried putting the xml into layout-notlong-hdpiand layout-long-dpi respectively, but both my WVGA and FWVGA emulators go for the "long" version (as described in the doc).
Is there any way to distinguish between the two besides using the deprecated -800x480/-854x480 qualifiers?
Android :: Populating Custom Layout From Xml Resource
Aug 8, 2010I have created a custom list item layout just like in this article http://developer.android.com/resources/articles/layout-tricks-efficie....
Each list item has icon, title and summary.
I would like to declare an xml resource that would provide data for that list. Just like you use <string-array> to populate the list using ArrayAdapter<String>.
The simple ArrayAdapter<String> can be populated from:

I need each <item> to have icon, title and summary. Somewhat similar to:

Android :: Using Resource Values As Layout Attributes - Config.xml
Mar 28, 2010Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations.
Given the config.xml:
<resources>
<string name="config_somePadding">50dip</string>
</resources>
How would I reference this to use as the layout_height in a layout xml file?
@string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.
In the sdk, they use an integer for animation duration. They reference it like this: android:duration="@android:integer/config_longAnimTime". Is there a way to use values that aren't integers in the layout_height attribute?
