Threre is a unique resquirement for my project.
I need to create a custom scrollbar for a listview.
I can do this task by setting drawable for scrolllbar.But that does not fulfill my requirement.
There are arrows in scrollbar drawable image and when clicked on them,particular list item should get selected.
So I need to use custom scrollbar for this requirement.

The problem appears in Android 2.2. It seems cool because it can auto-hide.But I don't like it quite much because the bar is an indicator for "Whether there is more content not present on the widget". Hiding it maybe neat, but may get the users wrong sometimes. In ListView, I find it a fatal bug at all. When there is more content to show, no scrollbar present, AND when wipe the screen down-wards, no scroolbar appears. Only when use the traceball or Dpad to move focus, there appears the scrollbar. BUT THERE IS WORSE: when you wipe down-wards to move the scrollbar down, nothing happens! The touch feature is almost disabled here.

I want to place both components under single verticle scrollbar, means i do not want scrollbar only for listview, currently i am achieving following layout through placing things in tableview but i want functionality like listview items..
How can I autohide scrollbar in ListView? I thought there would be an autohide attribute for ListView but there isn't. What I want to do is scrollbar is hidden at first when I touch the listview, scrollbar appears 2~3 seconds after the touch off, scrollbar disappears again.
View 3 Replies View RelatedI want to hide a listview's scrollbar when the listview isn't scrolling and show it when scrolling. I know this can be done very easy by setting "android:fadeScrollbars" as an application style if the API is 5 or newer. But I want the feature to be available on all android devices. So I've implemented the "setOnScrollListener" method, and switched the scrollbar visibility using the setVerticalScrollBarEnabled method. This works great on G2. The problem is that on Motorola Milestone the SCROLL_STATE_IDLE event isn't received when the scrolling stops, and so the scrollbar remains visible.

The scrollbar appears at the side as expected, but how do I get the scrollbar to expand and become controllable in the same way it behaves in the Contact list? Ideally I'd like all the Contacts list functionality for my app - i.e. to allow me to control the scrollbar directly with a finger and to show the first letter of the list elements you're currently scrolled to.

I have a LinearLayout layout with a ListView in it. I've made the android:background of the LinearLayout (I've also tried it on the ListView) be an image that I would like for my background.
This works fine enough. However, when I start scrolling through the ListView, the background often disappears and becomes black. If I move it around some more I may be able to get it to appear again. It would seem that Android is drawing over, or perhaps painting what's behind my background onto the items.

I have a listview with a custom row layout I can't seem to working although it shouldn't be complex. I need of the list row to insist of:
Icon -- title text (bigger and bold) with a short multi line text under the title -- ImageButton
My problem in most of my tests is the icon to the right usually doesn't appear, I guess my center group grows and takes all the space of the button. My last failed attempt was with a Relative Layout, didn't have too much luck with a Linear Layout either.
Here is the row XML:

I am running a sqlite query and binding the returned data to a ListAdapter.

Here is the code from the andriod tutorial

We'll define a custom screen layout here (the one shown above), but typically, you could just use the standard ListActivity layout. setContentView(R.layout.custom_list_activity_view) ;
Query for all people contacts using the Contacts.People convenience class. Put a managed wrapper around the retrieved cursor so we don't have to worry about requerying or closing it as the activity changes state.

Now create a new list adapter bound to the cursor. SimpleListAdapter is designed for binding to a Cursor.
CODE:................
Specify the row template to use (here, two columns bound to the two retrieved cursor rows). mCursor, // Pass in the cursor to bind tonew String[]{People.NAME, People.COMPANY}, // Array of cursor columns to bind to. new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.

I have an ExpandableListView that I want to populate with my custom views of type NoteView. NoteView extends LinearLayout and contains two buttons and a checkbox. I have almost everything working, the NoteView's are being populated with backing data, the lists are getting filled, and the buttons are clickable and perform the required tasks.
The problem is the ExpandableListView no longer responds to click/longclick/keypress events at all (other than selecting list items with trackball/DPAD).
I replaced my custom view with a standard TextView and the touch events flowed normally again, so it is almost certainly something I am doing wrong with my custom view or some obscure ListView setting I am overlooking.

View 2 Replies View RelatedI think I've tried everything(made focusable:false!!) and I cant capture in anyway the selected checkbox on my list item. Even OnItemClickListener, doesn't respond to any click. How can I retrieve checked checkboxes in my list item? My list item included: image view, 4 textviews and the checkbox. Some code:
this is in my ListActivity class:
final String columns[] = new String[] { MyUsers.User._ID, MyUsers.User.MSG, MyUsers.User.LOCATION }; int[] to = new int[] { R.id.toptext, R.id.bottomtext,R.id.ChkBox, R.id.Location}; Uri myUri = Uri.parse("content://com.idan.datastorageprovider/users"); Cursor cursor = getContentResolver().query(myUri, columns, null, null, null); startManagingCursor(cursor); ListCursorAdapter myCursorAdapter=new ListCursorAdapter(this, R.layout.listitem, cursor, columns, to); this.setListAdapter(myCursorAdapter);
And this is my Custom Cursor adapter class:
public class ListCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public ListCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout;
} @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); return v;
} @Override public void bindView(View v, Context context, Cursor c) { TextView topText = (TextView) v.findViewById(R.id.toptext); if (topText != null) { topText.setText("");
} int nameCol = c.getColumnIndex(MyUsers.User.MSG); String name = c.getString(nameCol); TextView buttomTxt = (TextView) v.findViewById(R.id.bottomtext); if (buttomTxt != null) { buttomTxt.setText("Message: "+name); } nameCol = c.getColumnIndex(MyUsers.User.LOCATION);
name = c.getString(nameCol); TextView location = (TextView) v.findViewById(R.id.Location);
if (locationLinkTxt != null) { locationLinkTxt.setText(name);
}
I've tried many ways. many listeners, can't figure how to capture listener to my checkboxes. The data I am binding to the list items from the database, isn't concerned about the checkbox.. only the textviews. There isn't any connection between the database and the checkbox I have in the list's item.

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 a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);
Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };
Is it possible to apply a custom background to each Listview item via the list selector?
The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible.
I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place.
For reference, this is the selector I'm using to try and get this working:

And this is how I'm setting the selector:
