View 1 Replies View RelatedI have a TextView with location data that I want to Linkify. When link will be clicked an Intent should be fired that will start Maps. How should I achieve this effect?
UPDATE:
I have something like "My street 9, My city". Now I want to have all this text to appear like a link and have intent fired with URI: geo:0,0?q=My+street+9,+My+city
Using just Linkify.ALL doesn't work.
I have seen examples implementing a custom Filter. The Android developer docs talk about implementing a Filterable interface. Does anyone have any advice and/or sample code on the best way to implement filtering in a ListView ?

I have a Custom Cursor Adapter. It shows a list of installed applications with an icon, name and checkbox on each line item. I cache the list of applications in a database for faster retrieve and to store the state of the checkbox. However, I can't store the application icon in the db because sqlite doesn't support blobs. They list works rather well except that it is "janky" as described by Brad Fitzpatrick at Google IO (https://wave.google.com/wave/waveref/ googlewave.com/w+3kgmObZwO ). I'm trying to make my app non-janky by following the tutorial here: [url]... but I'm having trouble.
The reason my list is janky is because I look up each icon as you scroll down the list. drawable = pm.getApplicationIcon(c.getString(c.getColumnIndex(SmartLockDbAdapter.KEY_PACKAGE)));
getApplicationIcon takes too long to return to make for a smooth scrolling list. I would like to perform the action in the background with an AsyncTask but because bindView gets called repeatedly in a short time span, my icons end up with the wrong list item. I need help.
I've posted my whole ListActivity below in hopes that it helps other people. It's much harder to find an example of a working CursorAdapter then it is an ArrayAdapter.

I have a listview with a custom arrayadapter that handles about 15 strings. The style of each row alternates (between labels and values for those labels--for example row 1 could be "email address" and row 2 would be the actual email address). I'm changing the style of each row to alternate like this in the arrayadapter's getView() method. So if the item at the current position is a label, I'll change the styling from the default row style (which is what the values have applied to them). When the listview first loads, the styling is perfect and just how I want it to be. If I scroll the list slowly up or down, it stays that way. However, if I scroll the list fast up and down, the styling of the value rows starts changing to that of the label ones until all of the rows have the styling of a label row. I've used custom adapters on other listviews in the app with no problems like this. Found out that it also changes all of the rows to the label styling on portrait->landscape orientation changes. Doesn't do this on landscape->portrait changes. Below is the adapter I'm using.
public class DetailsAdapter extends ArrayAdapter<String> { private TextView text = null; private String item = null;
public DetailsAdapter(Context context, int resource, int textViewResourceId, String[] objects) { super(context, resource, textViewResourceId, objects);
} @Override public View getView(int position, View convertView, ViewGroup parent) { text = (TextView) super.getView(position, convertView, parent); item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { text.setBackgroundColor(0xFF575757); text.setTextSize(15);
text.setTypeface(null, Typeface.BOLD); text.setPadding(8, 5, 0, 5);
} else { text.setPadding(15, 15, 0, 15); } return text;
} @Override public boolean isEnabled(int position) { item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { return false;
} else { return true; } } }
I'm making a custom adapter so that I can display a list of items with icons which looks like the menu that comes up when you long click the home screen. For some reason though the list items are not clickable. The can be navigated to with the D-pad but they cannot be clicked in any way. I thought maybe the problem was with the AlertDialog I was using so I replaced a working adapter I had elsewhere but I have the same issue there. My adapter looks like this:
ArrayList<IconListItem> mItems; LayoutInflater mInflater;
public IconListAdapter(Context context, ArrayList<IconListItem> items) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mItems = items;
} public IconListAdapter(Context context) {
this(context, new ArrayList<IconListItem>());
} public void add(IconListItem item) { mItems.add(item);
notifyDataSetChanged(); return item;
} public void remove(IconListItem item) { mItems.remove(item); notifyDataSetChanged();
} @Override public int getCount() { return mItems.size();
} @Override public IconListItem getItem(int position) { return mItems.get(position);
} @Override public long getItemId(int position) { return position;
} @Override public View getView(int position, View convertView, ViewGroup parent) { View view;
if(convertView == null){ view = mInflater.inflate(R.layout.two_line_icon_list_item, null);
} else { view = convertView; } IconListItem item = mItems.get(position);
TextView lineOne = (TextView) view.findViewById(R.id.firstLine);
TextView lineTwo = (TextView) view.findViewById(R.id.secondLine);
ImageView iconImage = (ImageView) view.findViewById(R.id.icon);
lineOne.setVisibility(View.VISIBLE); lineTwo.setVisibility(View.VISIBLE);
iconImage.setVisibility(View.VISIBLE); lineOne.setText(item.getText());
if (item.getSubtext() == null) lineTwo.setVisibility(View.GONE);
else lineTwo.setText(item.getSubtext());
if (item.getIcon() == null) iconImage.setVisibility(View.GONE);
else iconImage.setImageDrawable(item.getIcon());
return view; }
And the XML it's inflating:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="6dip" >
<ImageView android:id="@+id/icon" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_marginRight="6dip" />
<LinearLayout android:orientation="vertical" android:layout_width="wrap_content"
android:layout_weight="1" android:layout_height="fill_parent" >
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1"android:gravity="center_vertical"
android:id="@+id/firstLine" android:ellipsize="marquee" android:inputType="text" />
<TextView android:layout_width="wrap_content" android:layout_height="0dip"
android:layout_weight="1" android:ellipsize="marquee"
android:id="@+id/secondLine" android:inputType="text" />
</LinearLayout> </LinearLayout>
When I say they are not clickable, I mean that they items do not highlight in orange when I press them nor does onItemClick ever get called. In my code I have this, a different adapter for another purpose and it works perfectly
this.foos= foos; fa = new FooAdapter(this.foos); fooList.setAdapter(fa);
// View the details for an item when it is selected
fooList.setOnItemClickListener(new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MyActivity.this, MyOtherActivity.class);
i.putExtra("foo", ((fooAdapter)arg0.getAdapter()).getItem(arg2));
i.putExtra("list_position", arg2);
MyActivity.this.startActivityForResult(i, 0);
} } );
But when I swap out the first 3 lines for
IconListAdapter ila = new IconListAdapter(this);
ila.add(0, "Test 1", android.R.drawable.ic_menu_mylocation);
ila.add(0, "Test 2", android.R.drawable.ic_menu_edit);
ila.add(0, "Test 3", android.R.drawable.ic_menu_search);
groupList.setAdapter(ila);
I t stops working.
I have implemented a custom adapter the extends from the BaseAdapter and implements the getView method. It works fine except for one thing, not once do I get the convert View (a parameter to the getView method) that is not null (that can be reused).

I have a listView using a custom adapter. Each row contains a button and some other Views. I want to be able to click either on the button, or on the row itself (to edit the item of the list that is clicked).
Setting an onItemClickListener in the activity won't work because of this problem
I think I have to set an onClickListener in the getView() method of my adapter for it to work properly.
I would like to use my activity's onClickListener, in order to use a startActivityForResult() when the row is clicked, in order to have something returned to my activity when the item edition activity is over.
How can I do that?
I have a custom list adapter contains a layout with controls in it. I was wondering how I can get each individual controls id? I am planning on changing the color of some textviews. code...
View 1 Replies View RelatedI 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;
} }
I developed a List View with a custom adapter (which extends Array Adapter). The problem is that i can't selected or highlighted items. Is there a attribute to fix in the list View Layout or something else?
View 22 Replies View Relatedmade a custom list adapter extending the Base adapter. Each item in the list has an imagebutton, 2 textviews and a button. I tried to add the context menu to the list so as to display some options for an item in the list. registerForContextMenu(getListView()); I used a MenuInflater object to inflate the context menu xml file. But on clicking the items in the list nothing shows up or the usual highlighting of the item of list on click isn't shown. Is it that the context menu doesn't work for custom list views? Any help would be much appreciated.
View 1 Replies View RelatedI've got a schedule Class, which is simply a custom ViewGroup (with custom onMeasure() and onLayout()), which enables me to place childs(=events) with LayoutParams for column/row start and column/row end. The number of childs and their LayoutParams depend on database entries.
Now I'm trying to add childs (events) from my database. I'd have to use a Cursor Adapter, so my schedule Class has to extend ListView, right? I tried that but the newView() method of the adapter is never called. Why not? My custom ListView doesn't ask the adapter for childs, no childs are added. I also can't add the childs by hand calling schedule.addView() if I extend from AdapterView.
How can I add events to the schedule with the data from the cursor?
I'd like to make a list adapter that formats views like this:

When creating a custom account and/or sync adapter, raw_contacts that belong to your custom account can be created. But it looks like that they then cannot be edited with the Contact app! Is this a known limitation, or a problem in my code?
