View 2 Replies View RelatedI'm developing an application which has an listview. I'm currently creating the list item view dynamically from code (linearlayout, which includes 2 textviews and 1 imageview), but i'd like to use an XML resource for this. I read it is resource intensive when getting this view using findViewById within a loop. I thought of using a custom adapter for this, but am not sure on how to include lazy loading of the image then.

View 2 Replies View RelatedI'm using BaseExpandableListAdapter, and there is a drop-down button (looks like an arrow) on the left side for each parent item to indicate that you can expand that item to view child items. The question is: How can I change the properties of that drop-down button such as its position? I basically want to move it a bit lower in each parent item.

View 1 Replies View RelatedI am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item.I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array?What is the best way to do this?

View 1 Replies View RelatedHow to load data in expandable List Adapter through Scroll .
Means I want to add data as per Scrolling in Run time.
I am looking to find out how to assign an image to a imageview in each child of an expandable list.
If anyone has any information or links to find out how to do this. code...
is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start.
I am playing around with this example.
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList2.html
I cannot figure out how to attach a listener to the children elements so that I can trigger some action when the user taps on the phone number.
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).
View 1 Replies View RelatedI am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.
I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

View 13 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I just got my droid 2. All set up and rolling. However, I am adding shortcuts to my contacts on my desktop (ala the d1) by pressing and holding the screen, then Shortcuts > Contact. I scroll to the contact and select it. and it adds them to the home screen. Unfortunately, it adds them with the WRONG icon. It IS an existing icon for a user just not the user I am selecting. Also: It is only when I add it to the home screen as a shortcut when it gets jacked. Anyone else seeing this or have a solution? Also, I use google to sync all my contacts. I use Gmail to set the icons. There is only a certain size which can be used. but on the D2, the same contact icons/images seem to be blown out. Like I COULD use a bigger size image, bug I dont think that Google allows it? Anyone know what size contact image the 2 can handle and a way to use that image through Gmail? So far, moving from a D1 to a D2Im not completely impressed. but it is faster and works well. except for this issue. And the moto blur crap. Also to note... when using the (HORRIBLE) motorola contact widget the icon/image IS correct. but cmon, is this widget even useful? How many people have only one number? And I need a 4x4 widget for one contact... mobile, home, text, email, etc.. BS. Really the function on the D1 of adding a shortcut to a contact is much better. add em, click the icon, then it asks you what you want to do (text, call, email, talk, etc)... the D2 still does this but you have to go into Contacts and click on the person first before getting the options.
View 1 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.
