I have dynamic listview activity it transfer the item to another activity that have edit text(name,phone,table) and another dynamic listview under that.
the each item have edit text it should send with each item.

my problem is how to call the data from edit text to add it with the each item
for example the item name is :"Cheese Pizza" i want it "2 Cheese Pizza"

if (item_ids.length() == 0)
return false;
else
item_ids.deleteCharAt(item_ids.length() - 1);
Log.d("OrderPreview", item_ids.toString());
item_names = new StringBuilder();
for (int i = 0; i < orderItems.size(); i++) {

Write a method in your adapter to add new items in existing list of items.
and call that method in your async task when you are getting new dataset from your services/APIs.. Do not forget to put notifyDataSetChanged() in that method inside adapter.

you are adding hash map in the array list but in the adapter you are trying to get data from the hash map, instead of that you need to take value from arraylist which will return hashmap object and from that object you need to get value for your keys.
hope this will help.
I have a custom baseadapter that creates comment boxes. Everything works great on it until I want to add data. When I try to add the data it deletes the previous data and adds the new data. How do I make it so it keeps all the data? Is my Add method incorrect? Here is my baseadapter,

Setting the adapter:
final CreateCommentLists mycmlist = new CreateCommentLists(comments, usernames, numbers, DashboardActivity.this);
lstComments = (ListView)findViewById(android.R.id.list);
lstComments.setAdapter(mycmlist);
This is what how I call the add method,
mycmlist.add(comments,usernames,numbers);
mycmlist.notifyDataSetChanged();
In your add method you're setting the arrays to new values listComments = comments; That's replacing your old data with the new data.
You could use System.arrayCopy() to resize your listArrays to the new size and append the new items. A much less tedious approach, however, would be to store your arrays as List<String>, allowing you to add more items without worrying about resizing lists.
The result would look something like this...
public class CommentsAdapter extends BaseAdapter
{
private LayoutInflater inflater;
private List<String> comments;
private List<String> numbers;
private List<String> usernames;
public CommentsAdapter(Context context)
{
inflater = LayoutInflater.from(context);
comments = new ArrayList<String>();
numbers = new ArrayList<String>();
usernames = new ArrayList<String>();
}
public void add(String[] comments, String[] numbers, String[] usernames)
{
this.comments.addAll(Arrays.asList(comments));
this.numbers.addAll(Arrays.asList(numbers));
this.usernames.addAll(Arrays.asList(usernames));
notifyDataSetChanged();
}
#Override
public int getCount()
{
if (comments == null)
return 0;
return comments.size();
}
#Override
public String getItem(int position)
{
return comments.get(position);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
if (convertView == null)
{
convertView = inflater.inflate(R.layout.list_item, parent, false);
convertView.setTag(new ViewHolder(convertView));
}
ViewHolder holder = (ViewHolder) convertView.getTag();
holder.commentView.setText(comments.get(position));
//Other view bind logic here...
return convertView;
}
private static class ViewHolder
{
public TextView commentView;
public TextView numbersView;
public TextView usernamesView;
public Button usernameButton;
public Button numberButton;
public ViewHolder(View v)
{
commentView = (TextView) v.findViewById(R.id.listComment);
numbersView = (TextView) v.findViewById(R.id.listNumber);
usernamesView = (TextView) v.findViewById(R.id.listPostedBy);
usernameButton = (Button) v.findViewById(R.id.listUsernameButton);
numberButton = (Button) v.findViewById(R.id.listNumberButton);
}
}
}
I also highly recommend reading this page on the Android Developer's site: http://developer.android.com/training/improving-layouts/smooth-scrolling.html
Your current adapter implementation is very inefficient, and that page should help you iron out some kinks.
You probably need to add the String[] array to the existing one, instead of replacing it.
Add this function which joins two arrays (Sadly there is no already-implemented method for Java):
String[] concat(String[] A, String[] B) {
String[] C= new String[A.length + B.length];
System.arraycopy(A, 0, C, 0, A.length);
System.arraycopy(B, 0, C, A.length, B.length);
return C;
}
Credits: Sun Forum
And then change the add method to this:
public void add(String[] comments, String[] usernames,
String[] numbers) {
listComments = concat(listComments, comments);
listUsernames = concat(listUsernames, usernames);
listNumbers = concat(listNumbers, numbers);
}
And you had a typo in your code. In the add method, the listUsernames and listNumbers should be swapped I think.. I fixed it for you.
I have list with a check box in it and when i tick the check box by scrolling the list i get the values into an array.
But now the problem is i have a search box to search and tick.but when i search i get the element which is last ticked into array.
here is my code.

I have an application with three textviews and one checkbox in each row of a listview.what I want that on a click of a button I will be able to get the state of each checkbox and the row corresponding to (isChecked) checkboxes get deleted.one more thing my checkboxes are hardcoded in an xml file.I have searched a lot but couldn't find anything specific.thanks in advance.HERE IS MY CODE...

Try this:
Inside your getView(...) method...
final CheckBox lChk = ((CheckBox) pConvertView.findViewById(R.id.myChkBoxID));
private List<lisInfo> m_lisInfo = new ArrayList<lisInfo>();
lChk.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// Populate the listInfo with check box status
m_lisInfo.get(lPosition).setChkBoxStatus((isChecked));
}
});
public class lisInfo{
private boolean chkBoxStatus;
public boolean isChkBoxStatus() {
return chkBoxStatus;
}
public void setChkBoxStatus(boolean chkBoxStatus) {
this.chkBoxStatus = chkBoxStatus;
}
}
Now iterate the listInfo wherever required to get the check boxes statuses in the list view
maintain an array of boolean inside adapter . set listener on ckeckbox in getview which will swipe values of array on check/uncheck .
now make this array accesible in activity where on button
click()
{
for(int i=0;i<array.size;i++)
{
if(array[i])
adapter.deelet(item i);
//modify syntax
}
}
