android-listview

问题 I have a Listview with two adapters. They receive an Array with some data and when scrolled to bottom of the listview more data is loaded into the Array and here the listview should add the new data. Question: How can I make the listview reflect the new data and why isn't it updated when I call adAdapter.notifyDataSetChanged(); ? Fragments inner class where I download data & update UI in onPostExecute: @Override protected void onPostExecute(String result) { super.onPostExecute(result);

问题 I have a problem with setting the click event in a list view item. This is how the list is shown in the default situation: This is how it looks when I press the red image (the red turns to blue): and this is when I press the list item: As you can see, the red image turns to blue also, Even though I didn't pressed the button. What I want is that when I press the list item there is no change to the red image, and it remains the same. I tried to add android:drawSelectorOnTop="true" to xml file

So my point is, is there any way to get the status inside the ListView activity or ArrayAdapter so that I can make the changes

问题 I have a ListView with rows that contain ImageButtons (shown as 'O' below): [<-------TextView-------> O O O] [<-------TextView-------> O O O] I am finding that the first row has intermittent behaviour. At first it appeared that the image button onclicklisteners were not being called for just the top row. What I have found is that the onclicklisteners for the buttons do get called, but the clicks seem to be queued/buffered until I click on the row itself. I will happily post some code if
