Android :: Override Filter In Droid's ArrayAdapter?
Apr 19, 2010
I have an ArrayAdapter wrapped around an ArrayList of custom objects. I'd like to write a custom filter for that adapter so that when I call getListAdapter().getFilter().filter("abc") the list will get filtered by an arbitrary transformation of "abc".
I thought I would just try to override ArrayAdapter.getFilter(), but that requires I re-implement the private ArrayAdapter.ArrayFilter which requires access to a bunch of ArrayAdapter's private instances.
What's the simplest way to do this?

Anyone know of any apps that will allow a parent to set a content filter on the Eris so a kid can't access adult themed websites (porn etc)? The subject came up at work and it sounded like something worth looking in to, but the best I could find was a content filter service from Verizon (for free) but it seems that it also prevents Google Navigator, Facebook and YouTube from working properly (they all load just fine, but crazy error codes come up which prevent you from getting any further). Also of note: this only works when using the 3G service, as WiFi has no problems accessing Nav, FB and YT.

I'm running into difficulties overriding an ArrayAdapter to be displayed in a ListActivity. The ArrayAdapter is filled asynchronously. What I'm trying to do is add a special "sentinel" object that sits at the beginning of the list to show the progress of the computation. Ultimately this may be a progress bar, but right now I am just using a TextView as a placeholder. The problem is that the sentinel seems to get inserted multiple times into the list - not just once at the beginning. It *seems* to be appearing once per "page" of list data (so if 8 list items fit on the screen, my sentinel appears as the 1st, then 9th, then the 17th, etc..), but that interpretation may not be accurate. While maybe not how ArrayAdapters were intended to be extended, I thought something like this should work by simply overriding getView() to show my custom TextView for index.

I have a strange problem with one of my ListActivity. I have overrided the default ArrayAdapter in order to customize my list. I have then filled the adapter with an ArrayList.
If I insert an element on the list and then call notifyDataSetChanged() on the adapter everything works fine.
But if I insert an element at the END of the list and then call notifyDataSetChanged(), the new element doesn't appear ...
And finally if I override getCount() on my adapter like this :

I need some simple databinding for a Spinner. I want to display 2 items for each dropdownitem.
So when the user clicks the spinner I get a list like code...
I understand this can be done when using a Cursor, according to the databinding info on android dev. Like code...
However, I don't get my data from a database, so I don't use a cursor, I use a ArrayAdapter. Unfortunately it looks like there is no support for databinding with this adapter.
Is there a way to do this?

I am using an ArrayAdapter<CharSequence> to populate the items to list in a android.widget.Spinner. That works all fine. But now I want to keep the list of items dynamic, i.e. I want to be able to add/remove items from the selection list at runtime. However, when I call adapter.add(item) or adapter.remove(item) I always get a UnsupportedOperationException, even though the Javadocs of the ArrayAdapter class describe these two methods as to be usable for exactly that intended purpose.

I need a gallery to be able to hold up to thirty custom views. These views need to added or removed whenever, they also need to be able to be display in a display bow beneath the gallery. How do I do this?I looked at the doc file for arrayadapter but it requires me to use a reference Id for each view I add, but each view is all java coded. Should I just use setId upon creation of the view and just throw that id into the array adapter, or is there a way to create one without using resource id's?

I have a ListView that has some minor visual preferences that are set in a PreferenceScreen. These preferences are simple booleans to show or not to show some specific TextViews on each item in my ListView.
Anyhow, when these preferences are changed, I need to notify my ArrayAdapter that the data has changed in order to get the list redrawn. However, doing this via an OnSharedPreferenceChangeListener wouldn't really be optimal because there are several preferences that you can change, that would cause an unnecessary amount of updates to the ArrayAdapter.
So, to the question: How can I identify when my ListActivity has occurred on the screen after closing my PreferenceActivity, which I then could use to check for changes in the preferences, and only then notify the ArrayAdapter.
The ArrayAdapter being an inner class of my ListActivity, which is set as a ListAdapter.

I read the Avoiding Memory Leaks article with interest, and am concerned about danging references to the context object. I have a class like the following.
CODE:.........
Is it a problem to have a reference to a LayoutInflater object, since it must be using the context object somehow? Is there a better design pattern for what I'm trying to do here? (Use the context only to initially inflate the XML; from then on just use the View that's passed in to getView)

I have an ArrayAdapter powering a ListView. I would like to change the data behind the ArrayAdapter and update the ListView's. Sounds like notifyDataSetChanged(); would be exactly what I am looking for, but it updates the entire ListView, and I would prefer to update on a row-by-row basis.
Is there a way to do this with ArrayAdapter, or do I need to manage my data some other way if I want this functionality?

Currently my ListView is filling up with the given String[] but I wanted to alternate some styles on the ListView items. Something weird is happening (I'm surely missing something obvious); The ListView Index is not fixed and the styles are not alternating as supposed. My Code is the following:
import android.app.ListActivity;
import android.content.Context;
import android.graphics.Color;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;..................

I have a ListActivity based on an ArrayAdapter with setTextFilterEnabled set to true. This works fine on a device with a physical keyboard. When I start typing something on the keyboard, the items get filtered.My question is how to get the same behavior on a device with no physical keyboard?

I want to add some views in each row of list view. When I add text view and image view in getView() of ArrayAdapter,it works. But after I add other kind of views (like Check Box and Image Button...), I can't select the list row touching down screen directly, I only can select by key down, up and ok.
