How to make 1st item focus in ListView by default whenever enter the list View screen?

In my list View ,i have to make 1st item to be focused.In my app i have done D-PAD implementation,If i found the initial focus ,i will navigate the focus by using D-PAD.
i tried with setSelection(position) this code is not working.
I found some strange behaviour of listview,by default it always focus -1 position.I dont know why?,please clarify this behaviour.
My list view items are get load from server.So,when i have to make setSelection() and how to check the setAdpter task completed or not?.
#Override
public final View getView(final int position, final View convertView, final ViewGroup parent) {
final LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.list_item_faq, parent,
false);
final TextView textView = (TextView) rowView
.findViewById(R.id.faqlist_text);
textView.setText("text");
textView.setMaxLines(2);
textView.setEllipsize(android.text.TextUtils.TruncateAt.END);
return rowView;
}
adapter.xml
<?xml version="1.0" encoding="utf-8"?>

Please suggest any idea to make 1st item Focus.

Is your yourListView focusable?
Do in onResume()
yourListView.postDelayed(new Runnable() {
#Override
public void run() {
yourListView.setSelection(0);
yourListView.getChildAt(0).requestFocus()
}
}, 500);

Try doing the following:
public void onStart() {
super.onStart();
onListItemClick(listView, findViewById(android.R.id.content), 1, 0);
}
public void setActivateOnItemClick(boolean activateOnItemClick) {
listView.setChoiceMode(activateOnItemClick ? ListView.CHOICE_MODE_SINGLE
: ListView.CHOICE_MODE_NONE);
}

You might need to give a little bit of delay before using set selection.
listView.postDelayed(new Runnable() {
#Override
public void run() {
listView.setSelection(0);
}
}, 500);

Try this
listView.getAdapter().getView(position, null, null).performClick();

if you already try list.setSelection(position) then try
list.setItemChecked(0, true);
I hope it works for you. but remember, update this in main thread or ui thread
UPDATE
also try this
list.setFocusable(true);
list.requestFocus();
UPDATE 1
When u get all list from data then call
adapter.notifyDataSetChanged();
list.setSelection(position);

Could you show me code getview method in Adapter?
I think you set static viewholder in Adapter.
You should delete if(convertView == null) condition.
Look like:
// if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(
R.layout.baseadapter_dropdown_layout, null);
holder.img = (ImageView) convertView.findViewById(R.id.imageView1);
convertView.setTag(R.layout.baseadapter_dropdown_layout, holder);
// } else {
// holder = (ViewHolder) convertView
// .getTag(R.layout.baseadapter_dropdown_layout);
// }

In the onResume() go for
mListView.setSelection(position);
or
mListView.setSelection(listview.getAdapter().getCount()-1);
also
mListView.requestFocus();
also try to manage null check before entering hard coded positions.

Use performItemClick. It will call the OnItemClickListener, if it is defined. This works in charm for me.
int setPosition = 0; // Your default position. Any value less than your list size.
int ignoreId = 0; // We ignore the row id of the item that was clicked.
yourListView.setItemChecked(setPosition, true);
yourListView.performItemClick(yourListView.getSelectedView(), setPosition, ignoreId);

There is no need to use post with listview you can simply use listView.setSelection(0) after adding the data into the list

CheckBox in ListView being reset when it leaves the screen

I have followed the tutorial here to create a custom ListView that shows items with category headers. I have modified the list_item_entry.xml to put a CheckBox in the item:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingRight="?android:attr/scrollbarSize" >
<CheckBox
android:id="#+id/option_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="6dp"
android:focusable="false"
android:clickable="false" />
<TextView
android:id="#+id/list_item_entry_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:ellipsize="marquee"
android:fadingEdge="horizontal" />
</LinearLayout>
My problem is that if I check some of the CheckBoxes then scroll them off the screen, when they come back they are unchecked. However listView.getCheckedItemPositions() still shows that the item is checked.
I'm pretty sure that my problem is with the getView() method in my custom ArrayAdapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final Item i = items.get(position);
if (i != null) {
if(i.isSection()){
SectionItem si = (SectionItem)i;
convertView = vi.inflate(R.layout.list_item_section, parent, false);
convertView.setOnClickListener(null);
convertView.setOnLongClickListener(null);
convertView.setLongClickable(false);
final TextView sectionView =
(TextView) convertView.findViewById(R.id.list_item_section_text);
sectionView.setText(si.getTitle());
}else{
EntryItem ei = (EntryItem)i;
convertView = vi.inflate(R.layout. list_item_entry, parent, false);
final TextView title =
(TextView) convertView.findViewById(R.id.list_item_entry_title);
if (title != null)
title.setText(ei.getTitle());
}
}
return convertView;
}
I think that I have two issues here, though I have no idea how to solve either:
Using vi.inflate every time is causing android to constantly create views which is bad (not sure about this). I tried to only inflate it if convertView == null but then sometimes convertView would be in the wrong format, ie. List_item_section when it should be List_item_entry. Is it fine to inflate it everytime?
I think that inflating the view each time is causing the CheckBoxes to be reset, although I may be wrong about this.
So how do I make it so the CheckBoxes will stay checked when the leave and return to the screen? And will this method fill Android's memory with Views if the the list is sufficiently long?
Update:
I liked #user3815165's answer because I didn't need to store the checked value for a sectionItem which doesn't have a checkbox. But as I mentioned in a comment, since the items list is not in the context of the Activity then the values of whether each EntryItem is checked or not persists when the view is destroyed and creates bugs.
So I decided to go with #Palash's answer, even though it stored data not needed (only a single boolean value for each SectionItem in the list). It works perfectly.

you need to maintain a status array of type boolean in your activity, pass that array into your list adapter and while setting the checkbox check status of that position, also you need to update that status array likewise on click event of checkbox.
try this you will get the desired output.
//While Setting the checkbox in adapter
if(bStatus[position]==false)
{
itemSet.chSelectItem.setChecked(false);
}else if(bStatus[position]==true)
{
itemSet.chSelectItem.setChecked(true);
}
In your main Activity
//initilize Arraylist in main Activity
boolean[] bStatus;
bStatus = new boolean[BeanArray.size()];
Arrays.fill(bStatus, false);
MyAdapter adapter = new MyAdapter(this, BeanArray, bStatus);
listView.setAdapter(adapter);

class Item{
boolean isSection;
String title;
boolean isOptionChecbox;
//your getter/setter
#Override
public String toString() {
return title;
}
}
you Adapter:
public class listAdapter extends ArrayAdapter<Item> {
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final Item i = items.get(position);
if(i.isSection()){
convertView = vi.inflate(R.layout.list_item_section, parent, false);
convertView.setOnClickListener(null);
convertView.setOnLongClickListener(null);
convertView.setLongClickable(false);
final TextView sectionView = (TextView) convertView.findViewById(R.id.list_item_section_text);
sectionView.setText(si.getTitle());
} else{
convertView = vi.inflate(R.layout. list_item_entry, parent, false);
final TextView title = (TextView) convertView.findViewById(R.id.list_item_entry_title);
if (title != null) title.setText(ei.getTitle());
CheckBox optionCheckbox = (CheckBox) convertView.findViewById(R.id.option_checkbox);
optionCheckbox.setChecked(ei.isOptionCheckbox());
optionCheckbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
item.setOptionCheckbox(b);
}
});
}
return convertView;
}
}

Hide items in a listview

I have tried to hide items in a custom list adapter. I can hide the visibility of the text but I cannot hide the whole list item. It still shows the dividers etc. I have tried:
tv.setVisibility(View.INVISIBLE);
tv.setVisibility(View.GONE);
convertView.setVisibility(View.INVISIBLE);
convertView.setVisibility(View.GONE);
When I use the convertView i get a null pointer exception.

You can set ContentView with No Element.
In getView() of Your Custom Adapter.
if(condition)
{
convertView=layoutInflater.inflate(R.layout.row_null,null);
return convertView;
}
else
{
convertView=layoutInflater.inflate(R.layout.row_content,null);
return convertView;
}
your XML row_null.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>

You have 3 ways to do this:
Remove the items from your list inside or outside the adapter.
Inside the adapter you can do it in the Constructor.
private List<String> list;
public MyAdapter(Context context, List<String> list) {
list.remove(0);
list.remove(1);
list.remove(<whateverPositionYouLike>);
this.list = list;
}
You need to figure out how many items you want to hide and need to build a similar logic.
#Override
public int getCount() {
// In this adapter, we are supposed to hide the first item of the list view
// Returning 0 if no of items are already 0
if(list.size() <=1)
return 0;
// if number of items are more than one, returning one item less
return list.size() - 1;
}
#Override
public Object getItem(int position) {
// skipping the position
return list.get(position + 1);
}
`
#Override
public View getView(final int position, View v, ViewGroup arg2) {
// this is important, as we are supposed to skip the first item of listview
final int localPosition = position +1;
ViewHolderItem holder;
if (v == null) {
holder = new ViewHolderItem();
v = inflater.inflate(R.layout.list_row, null);
v.setTag(holder);
} else {
holder = (ViewHolderItem) v.getTag();
}
return v;
}
`

You cannot in the way you are trying to, you'll need to use a custom Adapter and implement in there the logic for showing/not showing a line.

If you want to hide a row in a listview, you need to delete data in that position. For example if you use array adapter and want to hide the row on 5. position. You have to delete line from your array and the call notifyDatasetChanged() method.
(You can delete data from array by using tempArray)
or use this way
private List<String> items = new ArrayList<String>();
// make list a new array, clearing out all old values in it.
for(i=0; i<10; i++)
{
if((i != 5) && (i != 6)){
// if k = 5 or 6, dont add those items to the list
items.add(something[i]); /// whatever your list items are.
}
}
ArrayAdapter<String> itemList = new
ArrayAdapter<String>(this,R.layout.itemlistlayout);
setListAdapter(itemlist);

If you want to hide an entire item you need to build some logic into your getView() method to make it skip over various parts of your data.
lets say you have an ArrayAdapter and I want to hide the data that is at index 2. Your getView() method could look something like this.
#Override
public View getView(int pos, View convertView, ViewGroup, parent){
View mView = convertView;
//TODO: Check if convertView was null, and inflate
// or instantiate if needed.
//Now we are going to set the data
mTxt = mView.findViewById(R.id.mTxt);
if(pos >= 2){
//If position is 2 or above, we ignore it and take the next item.
mTxt.setText(this.getItem(pos + 1).toString());
}else{
//If position is below 2 then we take the current item.
mTxt.setText(this.getItem(pos).toString());
}
return mView;
}
Note that this example is generalized, it is not meant to be able to be dropped directly into your project. I had to make assumptions about some things which I don't know the truth on. You can use the same concept as I've shown here though and modify it to your situation to be able to "hide" rows in your ListView.

If you already have a custom list adapter you can just call notifyDataSetChanged() on the adapter and the adapter itself has of course to implement the logic to filter out the views for the rows you want to hide. These are the methods that come to my mind that need to reflect that logic:
#Override
public Object getItem(int position) {
return mItems.get(position);
}
#Override
public int getCount() {
return mItems.size();
}
#Override
public View getView(final int position, final View convertView, final ViewGroup parent) {
// here goes your logic to hide a row
Additionally you might have to change getItemId() as well.

I think I have a much easier / safer solution: you just have to "embed" your item in a Layout, and change the visibility of this parent layout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<!-- Embed ListView Item into a "parent" Layout -->
<LinearLayout
android:id="#+id/parentLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<!-- This is the normal content of your ListView Item -->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="World" />
</LinearLayout>
</LinearLayout>
Then in your code just do:
public View getView(int position, View view, ViewGroup parent) {
if (view == null) {
LayoutInflater li = mActivity.getLayoutInflater();
view = li.inflate(R.layout.my_listview_item, null);
}
LinearLayout parentLayout = (LinearLayout) view.findViewById(R.id.parentLayout);
if (shouldDisplayItem(position)) {
parentLayout.setVisibility(View.VISIBLE);
} else {
parentLayout.setVisibility(View.GONE);
}
return view;
}
This way you always use/reuse the same item, and just hide/show it.

Can I make one ListView item have a different Text Color?

I have the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:id="#+id/ListView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1.0"
android:textColor="#android:color/white"
android:dividerHeight="1px"
android:listSelector="#drawable/highlight_sel"
/>
</LinearLayout>
And the code:
private ListView lv1;
private String lv_arr[]={"Item 1","Item 2","Item 3","Item 4"};
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.newsmenu);
lv1=(ListView)findViewById(R.id.ListView01);
// By using setAdpater method in listview we an add string array in list.
lv1.setAdapter(
new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
lv_arr));
}
I want the text color of Item 2 (or 1 or 3 or 4) to appear dynamically as red (denoting a new item) or white (default). Is there a way to do this?
I already have a selector present, which is why I used ListView. I've search the Internet and this site, and I have not seen this question broached.
So is it possible?

Yes everything is possible. you need to write your own adapter implementation basically overriding the getView Method in the adapter. search google and stack you will find many tutorials on how to write an adapter.

Writing a special adapter to override getView in simple adapter is the way to change the text color alternating on the lines of your choice in a listview. I took the example which has been repeated many times on this website and added a way to change the text color. position mod length to select the color position can be replaced with any scheme you like. The text view "business" can be the first line of your layout like mine--or use the android.R.id.text1.
public class SpecialAdapter extends SimpleAdapter {
private int[] colors = new int[] { 0x30FF0000, 0x300000FF };
public SpecialAdapter(Context context, List<HashMap<String, String>> items, int resource, String[] from, int[] to) {
super(context, items, resource, from, to);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
int colorPos = position % colors.length;
//view.setBackgroundColor(colors[colorPos]); //old example
TextView tv1 = (TextView)view.findViewById(R.id.business); //new
tv1.setTextColor(colors[colorPos]); //new
return view;
}
}
Just use SpecialAdapter instead of SimpleAdapter in your app.

Here's an example of a getView method. Note that it's using a viewholder for efficiency. If you want to know more about that, let me know.
public View getView(int position, View convertView, ViewGroup parent) {
tempDeal = exampleBoxArrayList.get(position);
ViewHolder holder;
if (convertView == null) {
convertView = inflator.inflate(R.layout.list_item_example_box, null);
holder = new ViewHolder();
holder.divider = (RelativeLayout) convertView.findViewById(R.id.example_box_divider);
holder.merchantName = (TextView) convertView.findViewById(R.id.example_box_merchant_name);
holder.expireDate = (TextView) convertView.findViewById(R.id.example_box_expire_date);
holder.description = (TextView) convertView.findViewById(R.id.example_box_description);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if (tempDeal.isDivider()) {
holder.divider.setVisibility(View.VISIBLE);
} else {
holder.divider.setVisibility(View.GONE);
}
holder.merchantName.setText(tempDeal.getMerchantName());
holder.expireDate.setText(tempDeal.getExpiryDateString());
holder.description.setText(tempDeal.getPriceOption().getDescription());
return convertView;
}
As you can see, I call the isDivider() method on my custom object (this method looks at a boolean set on data load). This method is used to turn the visibility of part of the layout on or off.
Alternatively, you could load a completely new layout based on this same concept.

Multiple choice list with custom view?

I'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 TextViews and 1 CheckBox, somewhat similar to the List3 example. I tried creating a custom layout file row.xml like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<CheckBox
android:id="#+id/checkbox"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="fill_parent" />
<TextView
android:id="#+id/text_name"
android:textSize="13px"
android:textStyle="bold"
android:layout_toLeftOf="#id/checkbox"
android:layout_alignParentLeft="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/text_phone"
android:textSize="9px"
android:layout_toLeftOf="#id/checkbox"
android:layout_below="#id/text_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
Then in Activity's onCreate(), I do like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Query the contacts
mCursor = getContentResolver().query(Phones.CONTENT_URI, null, null, null, null);
startManagingCursor(mCursor);
ListAdapter adapter = new SimpleCursorAdapter(this,
R.layout.row,
mCursor,
new String[] { Phones.NAME, Phones.NUMBER},
new int[] { R.id.text_name, R.id.text_phone });
setListAdapter(adapter);
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
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? Many thanks.

You have to make your own RelativeLayout that implements the Checkable interface and have a reference to the CheckBox or to the CheckedTextView (or a list if it's multiple choice mode).
Look at this post:
http://www.marvinlabs.com/2010/10/29/custom-listview-ability-check-items/

The answer of Rahul Garg is good for the first time the list is loaded, if you want some rows to be checked depending on the model data, but after that you have to handle the check/uncheck events by yourself.
You can override the onListItemCLick() of the ListActivity to check/uncheck the rows
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
ViewGroup row = (ViewGroup)v;
CheckBox check = (CheckBox) row.findViewById(R.id.checkbox);
check.toggle();
}
If you do so, do not set the ListView to CHOICE_MODE_MULTIPLE, because it makes strange things when calling the function.
To retrieve the list of checked rows, you have to implement a method yourself, calling getCheckItemIds() on the ListView does not work:
ListView l = getListView();
int count = l.getCount();
for(int i=0; i<count; ++i) {
ViewGroup row = (ViewGroup)l.getChildAt(i);
CheckBox check = (Checked) row.findViewById(R.id.ck1);
if( check.isChecked() ) {
// do something
}
}

Each such view has a TextView and a
CheckBox.
No, it doesn't. It has a CheckedTextView.
So what do I need to do to make a
multiple choice list with my custom
view for each row?
Try making the CheckBox android:id value be "#android:id/text1" and see if that helps. That is the ID used by Android for the CheckedTextView in simple_list_item_multiple_choice.

The solution is to create a custom View that implements the Clickable interface.
public class OneLineCheckableListItem extends LinearLayout implements Checkable {
public OneLineCheckableListItem(Context context, AttributeSet attrs) {
super(context, attrs);
}
private boolean checked;
#Override
public boolean isChecked() {
return checked;
}
#Override
public void setChecked(boolean checked) {
this.checked = checked;
ImageView iv = (ImageView) findViewById(R.id.SelectImageView);
iv.setImageResource(checked ? R.drawable.button_up : R.drawable.button_down);
}
#Override
public void toggle() {
this.checked = !this.checked;
}
}
And create a custom layout for the list items using the new widget.
<?xml version="1.0" encoding="utf-8"?>
<ax.wordster.OneLineCheckableListItem xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:background="#drawable/selector_listitem"
android:orientation="horizontal" >
<ImageView
android:id="#+id/SelectImageView"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#drawable/button_friends_down" />
<TextView
android:id="#+id/ItemTextView"
android:layout_width="fill_parent"
android:layout_height="60dp"
android:gravity="center"
android:text="#string/___"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#color/text_item" />
</ax.wordster.OneLineCheckableListItem>
Then create a new custom Adapter using the layout above.

It is possible by some trick
in your ListActivtyClass in method
protected void onListItemClick(ListView l, View v, int position, long id) {
//just set
<your_model>.setSelected(true);
}
now in you custom Adapter
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(textViewResourceId, parent, false);
}
if (<your_model>.isSelected()) {
convertView.setBackgroundColor(Color.BLUE);
} else {
convertView.setBackgroundColor(Color.BLACK);
}
return convertView;
}
this way you can customize the view in adapter when the item is selected in the list.

Simple example how to get a custom layout to work as custom checkbox:
private class FriendsAdapter extends ArrayAdapter<WordsterUser> {
private Context context;
public FriendsAdapter(Context context) {
super(context, R.layout.listitem_oneline);
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final int pos = position;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rv = inflater.inflate(R.layout.listitem_oneline, parent, false);
rv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
boolean checked = friendsListView.isItemChecked(pos);
friendsListView.setItemChecked(pos, !checked);
}
});
WordsterUser u = getItem(position);
TextView itw = (TextView) rv.findViewById(R.id.ItemTextView);
itw.setText(u.userName + " (" + u.loginName + ")");
ImageView iv = (ImageView) rv.findViewById(R.id.SelectButton);
if (friendsListView.isItemChecked(position)) {
iv.setImageResource(R.drawable.downbutton);
} else {
iv.setImageResource(R.drawable.upbutton);
}
return rv;
}
}

I found it very useful this little code: http://alvinalexander.com/java/jwarehouse/apps-for-android/RingsExtended/src/com/example/android/rings_extended/CheckableRelativeLayout.java.shtml
It is a great addition to #ferdy182 's http://www.marvinlabs.com/2010/10/29/custom-listview-ability-check-items/ content.

Got the solution ... You can get the clicks on the views (like checkboxes in custom layouts of row) by adding listener to each of them in the adapter itself while you return the converted view in getView(). You may possibly have to pass a reference of list object if you intent to get any list specific info. like row id.

I want to confirm that the Pritam's answer is correct. You need an onClickListener on each list's item (define it in the adapter's getView()).
You can create a new onClickListener() for each item, or have the adapter implement onClickListener() - in this case the items must be tagged for the listener to know, which item it is operating on.
Relying on the list onItemClickListener() - as someone advised in another thread - will not work as the CheckBox will intercept the click event so the list will not get it.
And finally #Rahul and JVitella:
The situation is that the CheckBox on a list item must be clickable and checkable independently from the list item itself. Therefore the solution is as I just described above.
