问题 I'm retrieving a list of strings from a webservice and I want to list them up on a AutoCompleteTextField regardless of the built-in AutoCompleteTextField filters. How do I do that? is there a way to disable it's inner filtering easily (preferably without subclassing) I've loaded all my results into a ArrayAdapter , the problem is that some of them don't show up because of the filtering.

问题 I'm using an ArrayAdapter to add items to a custom ListView and showing the results in my Android app. The problem I'm having is that the ArrayAdapter seems to wait until all items are in it before it shows the view. That is to say, when I'm adding the items to the ArrayAdapter and I call notifyDataSetChanged, it does not update the ListView to show the added item. It waits until all items are added and GetView is called before showing the items. What I would like it to do is to show the item

问题 I want to know the difference between using BaseAdapter and ArrayAdapter . I have been achieving what I want through ArrayAdapters . Does it affect the performance of the ListView on the adapter interface in which it is implemented ? And, the last question is, can i achieve anything doing with ListView using any of these Adapters , or, there are certain cases where specific adapter only can be used? 回答1: Here is the difference: BaseAdapter is a very generic adapter that allows you to do

问题 I have a dynamic ListView which uses an ArrayAdapter . When a name is selected from a spinner, the name together with an icon showing whether they are male or female gets added to the ListView . Mostly everything is good (the name gets added to the list correctly, together with an icon). But the icon showing the sex gets added to the wrong item in the ListView . The name gets added to the bottom of the list, but the icon gets placed at the name at the top of the list. I don't know if it's the

问题 I have a array list like this: private ArrayList<Locations> Artist_Result = new ArrayList<Location>(); This Location class has two properties: id and location .

So I think I have to set display the

问题 I have made a ListView with an ArrayAdapter. It works. But I had to put the resource id for the item layout twice: in the adapter definition and in the getView, in the case when the View parameter is null. // --------------------------------------------here is the FIRST use lvShows.setAdapter(new ArrayAdapter<TvShow>(this, R.layout.show_row, allKnownShows) { @Override public View getView(int position, final View rowView, ViewGroup parent) { LinearLayout showView; if (rowView == null) { // ---

问题 When overriding the baseadapter on an android listview, you have to implement this method public View getView(int position, View convertView, ViewGroup parent) . The convertview is the view that was previously pushed off the list when scrolling, and it's given so that you can reuse that view instead of creating a new view. My question is, is it really necessary to reuse the view? I can understand reusing it if only a piece of the data is changed. But is the overhead of creating a view really
