I want to add editText on click on button in listview.
i have created adapter for this to add edittext to listview.
but problem is only one edittext is in Listview. i want to create more than one when click on button.
Please help
Your ListView is (should be) backed by some sort of Adapter, which in turn, should be wrapping a Collection of data objects, perhaps a List or String[].
Upon click of the button, you should add the data to the Collection that is wrapped by the Adapter, and then notify the Adapter with notifyDataSetChanged()
There's a good tutorial at http://www.vogella.com/tutorials/AndroidListView/article.html

I am using using a ListView which has two Buttons and a EditText in it, button1 will change the edit text to "Clicked!" and button2 will delete the row whose button been clicked.
I am not finding any way how to do it from ActivityMain.
If you have a custom list view with a custom adapter, you can handle onclick listeners of buttons from within the adapter itself by first getting the view and then like
Button btn1 = (Button) yourview.findviewbyid(R.id.btnxx);
Note yourview.findviewbyid
You have to do a Adapter for your ListView. For first you should use RecyclerView instead of ListView. Make your own custom Adapter and use for example ArrayList to keep your items. Then if you would like to delete something you will have to remove it from ArrayList and call notifyDataSetChanged().
Here is the toutorial how to do it: https://developer.android.com/guide/topics/ui/layout/recyclerview
I have a listView with a edittext in all the rows of the listView and i want get all the changed editText values when i clicked to a button which is in same layout but is not part of the listView.
Please help me.
If you built your Adapter properly, your EditTexts will be recycled, so you won't have one EditText for all of your items. Instead, you should be saving the data to the backing array every time an EditText is updated (using a listener). When the user clicks on the button you should read the data from the backing array, not the actual ListView views.
I have two listviews with custom adapters. The first listview contains names of lists. When I click on the name of a list, the second listview have to be populated with the contents of the clicked list. I need to read the contents of the list from a local SQLite database that's located in assets, but that's not important. Assume that I have array of the contents. I know how to do this if I have to populate them on button click, but I don't know to do it this way. Both listviews are in the same activity.
by using onItemClickListener of listview u can do this.
on onitemclickListener of first listview u set adapter for the second listview
u can do this using one customadapetr and u can write separate customadapter for both
listview.
if u post some sample code i will try to give more specific answer
I have a list with checkboxes, what I need to know, is there anyway that when i click on the checkbox ONLY it will be checked and when i click on the list item i want to trigger a function but not to select the checkbox.
in other words, If I tap on any row , the check box should NOT be check unless I click on it directly.
here is my list:
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice , items));
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
I implemented this a while back, the thing to do is to use multiple layouts, one containing checkbox, another containing the text of the list item, and wrap it a relative layout, and add this as a row for each list item, i.e. use it to populate and create your row dynamically.
Now set an onClickListener for this list and within that block of code listen for identity of which view is getting the click and do different things.
^basically what the other commenter said. I personally think the easiest thing to do would first be get your layout perfect for a single list item, then make a scrollview, put a linearlayout in the scrollview, and populate the linearlayout with the individual list items using a loop. Set onClickListeners and such in the loop, or use a single onClickListener with different tags or ids for the list items...
I have an add button, a textbox called edittext, and a listview. When I click the add button data currently in edittext should move to list view. How can I make this happen?
set ArrayAdapter<String> for your
ListView
use insert method of
ArrayAdapter for move string from
EditText to ListView
http://developer.android.com/reference/android/widget/ArrayAdapter.html
"edittext should move to list view".. do you mean focus to be moved to listview OR Editext must disappear and listview must appear?
To handle focus you could use setFocusable() http://developer.android.com/guide/topics/ui/ui-events.html#HandlingFocus
For second option, you could hide widgets in event handlers.
#GSree it is very clear that user569553 wants that when he/she clicks on add button tha data of edittext feild should move to list.
so simply get data using getText() method and the go through this link.
best explanation i have ever found about implementation of getView() and listview.

If you're using an in-build list adapter such as ArrayAdapter or SimpleAdapter, then all you need to is add the data from EditText.getText() to your data collection, create a NEW list adapter, then when you call setListAdapter() the listview will be refreshed with your new item added.
