ListView in ScrollView - small bug

I'd like to have a listview in scrollview. This method is doing it almost perfect: https://stackoverflow.com/a/3495908/2811653 There is a bug when I enter more text in a row than fits in one line: 1: http://abload.de/img/screenshot_2013-10-311jq5t.jpg 2: http://abload.de/img/screenshot_2013-10-31lvrad.jpg Scrolling down to the button works fine BUT as you see in the second screenshot the P is not displayed correctly :-( In the Utility class the height is not calculated correctly when I fill the first row of listview like that.

After a tremendous amount of time searching in here, and everywhere else I am hopeless to find a solution. So here is my problem. I have created a list-view and on top of that I added a search-bar. When I use the search-bar, to filter the results... when I click on item 7, instead of opening the specific clicked activity i.e. 7, it always starts from the first one. I am looking forward to your help guys; because I need it! akhil batlawala public class Group extends ListActivity { // ArrayList thats going to hold the search results ArrayList<HashMap<String, Object>> searchResults; // ArrayList

Android - Getting database ID from ListView selection

随声附和 提交于 2019-12-02 08:34:44
I have a ListView lv which uses a Cursor c from an SQL database to populate it. When an item is selected however, I need to get the ID of the row. How can I do this? I assume that you are using a SimpleCursorAdapter (or similar), so I would use the OnItemClickListener : listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // id references the SQLiteDatabase _id column } }); Here's how it worked out for me. In an other class, I have created a method of List type and added the column id & the name

Advice needed with context menu

我是研究僧i 提交于 2019-12-02 07:55:00
I have a XML layout which has two edit text fields, one for "title" and the the other for "story". When the user enters his data in these text fields and presses the back button the entry gets saved in a list view as the title set. The list view is present in an activity say A1. Now A1 extends Activity. Whenever an item in the list is "long clicked" a context menu appears with edit, delete and read buttons. If the edit button is pressed I need to open another activity which can edit the data entered in the text fields corresponding to the item clicked. Also I'd be needing the id and the

Clear Android ListView

问题 I have a ListView. I want to dynamically change the contents of the listview.I used "adapter.notifyDataSetChanged();" to change the contents.
