Android :: Multi Column Custom List View / With Editable Edit Text At End Of List View
Nov 3, 2010I am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).
View 1 Replies View RelatedAndroid :: Multiple Choice List With Custom View
Apr 16, 2010I've seen example com.example.android.apis.view.List11 from ApiDemos. In that example, each row takes the view android.R.simple_list_item_multiple_choice. Each such view has a TextView and a CheckBox.
Now I want each view to have 2 TextView's and 1 CheckBox, somewhat similar to the List3 example. I tried creating a custom layout file row.xml like this:
CODE:...............
Then in Activity.onCreate(), I do like this:
CODE:..................
The result kind of looks like what I want, but it looks like the list doesn't know which item of it is selected. Also, I need to click exactly on the checkbox. In the List11 example, I only need to click on the item row.
So what do I need to do to make a multiple choice list with my custom view for each row?

View 3 Replies View RelatedAndroid :: Best Way To Create A Custom View For Every List Item?
Nov 4, 2010As I am reviewing and prototyping my android project, I noticed that there is a view that has a list of items that are very customized. I have figured out most of my tools that I plan to use but I need some advice.
I have a list of items which can contain photos, some text to the right, an image to the bottom and more text below that. Very confusing I know. Each of these might be present for an item. The only thing that will always be there is the title.
So my question - what is the best way to create each custom list item view? I am thinking I have to use this getView to create each view. But when creating each view, is it best to 1) create a view dynamically and adding an image, for example, if it exists, or 2) create an xml file with all possible elements and hide them depending on the item?
Android :: Filtered List View With Custom Adapter Not Updated
Mar 25, 2010I have a ListView with a custom Adapter that extends ArrayAdapter. It's ArrayAdapter of Type Artist. (There are about 1200 artists in my list). Artist is a very small class that has a name and an id. The Artist Class has toString() overridden to return just the name. I have an EditText. The EditText has an TextChangeListener where I call .getFilter().filter(chars, callback) on my adapter. In the Filter.Filterlistener().onComplete() callback i print the count and it looks really good. As i type the count decreases. So it seams everything works as advertised, but the List stays the same. I tried to call artistAdapter.notifyDataSetChanged() to force the list to redraw, but nothing happens. [see 2.)]. I am tinkering around for days now! I am desperate. Hopefully someone can have a look on my code and tell me what I am doing wrong! How can I force the list to be redrawn?
Here is what I have done:
1.) Defined a ListView and an EditText like this:
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_search_text"
android:layout_width="fill_parent"
android:layout_height="35dip"
android:layout_below="@id/header">
</EditText>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_search"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</ListView>
2.) Setup my ListView in the Activities onCreate():
private ListView listView = null;
private ArtistAdapter artistAdapter = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_artists);
artistAdapter = new ArtistAdapter(this, R.layout.row, list); // 'list' is an ArrayList<Artist>
listView = (ListView) findViewById(R.id.list_search);
listView.setAdapter(artistAdapter);
listView.setFastScrollEnabled(true);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View v, int position, long id) {
// do something } });
EditText txtSearch = (EditText) findViewById(R.id.list_search_text); txtSearch.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable arg0) { }
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
public void onTextChanged(CharSequence chars, int start, int before, int count) {
artistAdapter.getFilter().filter(chars, new Filter.FilterListener() {
public void onFilterComplete(int count) {
Log.d(Config.LOG_TAG, "filter complete! count: " + count);
artistAdapter.notifyDataSetChanged();
}});
}});
}
3.) This is my ArtistAdapter in short. I added an remove() and add() method:
public class ArtistAdapter extends ArrayAdapter<Artist> implements SectionIndexer {
private List<Artist> items;
/* other stuff like overridden getView, getPositionForSection,
getSectionForPosition and so on */
@Override
public void remove(Artist object) {
super.remove(object);
items.remove(object);
}
@Override
public void add(Artist object) {
super.add(object);
items.add(object);
} }
4.) My artist has also the toString() overridden:
public class Artist implements Comparable<Artist> {
public String uid;
public String name;
public Artist(String id, String name) {
this.uid = id;
this.name = name; }
public int compareTo(Artist another) {
return this.name.compareToIgnoreCase(another.name);
}
@Override
public String toString() {
return this.name;
} }

Aug 2, 2010I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException.

Android :: Graphically Represent Multiple List Selections / Dynamically Change List Item View
Apr 23, 2010I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

Android :: Combining Map View And List View In Application
Aug 4, 2010I am working on an application where I need to display some locations on a map and in a list view where the user should be able to toggle between these views(activities?). I want the toggle button(s) to be in my custom titlebar like in the images (if they are attached). What is the best practice for this? Tab view seems like a solution but can I customize the tab buttons? Should the map and list be in different activities or the same? Now I have two different activities one extending MapActivity and one extending ListActivity but no way to toggle between them. Is it possible to load activities into a FrameLayout?
