intent.putExtra("tag",productIDListArr[position]);
intent.putExtra("email", email);
context.startActivity(intent);
}
});
return rowView;
}
}
But when I run the code, it actually calls customAdapter.java but right after calling getCount() from customAdapter Its not calling getView and the application terminates.
One more thing... how can I update more items into existing list?

You app may crash in getCount method when productIDListArr is null. So add if condition in your getCount method before returning count.
For example :
public int getCount(){
if(productIDListArr==null){
return 0;
}else{
return productIDListArr.length;
}
}
Tips : Create a class for holding your response data and pass the list of that model class to the adapter and each time when there is any change in your data update that list and call notify method of adapter.
For example :
Class Item{
public String productIDListArr;
public String productNameListArr;
public String productDescListArr;
public String productImagesArr;
public String productStarsArr;
}
ArrayList<Item> items=new ArrayList<Item>();
for (int i=0;i<len;i++)
{
objectInArray = jsonArray.getJSONObject(i);
Item item=new Item();
item.productIDListArr=(objectInArray.getString("productId"));
.......
}
CustomAdapter extend BaseAdapter{
ArrayList<Item> items;
public CustomAdapter(ArrayList<Item> items){
this.items=items;
}
public int getCount(){
return items==null?0:items.size()
}

when I load ListView contain zero record empty list view not showed
Any help will appreciate thanks

Well, i wrote simple it will help you
Override onContentChanged() method
Like below:
#Override
public void onContentChanged() {
super.onContentChanged();
// write you code here, when list view empty.
}

Change the following:
mListview.setEmptyView(getActivity().
findViewById(R.id.emptyElement));
mListview.setAdapter(mAdapter);
to
mListview.setAdapter(mAdapter);
mListview.setEmptyView(getActivity(). findViewById(R.id.emptyElement));
Bind the listview first and then set the empty view.

Place the
mListview.setEmptyView(getActivity(). findViewById(R.id.emptyElement));
below
mListview.setAdapter(mAdapter);

onListItemClick is not working for listview?

Hi onListItemClick for listview is not working. Here i am fetching datas from SQLite using AsyncTask and displaying it in a list view. And i wants to do some actions when a list in a listview has clicked. But the click is not happening. I had tried a lot for this. Please help me.

</LinearLayout>

Add below code to your TextView in the XML
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
and try again.
Another simple solution: add android:descendantFocusability="blocksDescendants" to the root viewgroup.

You should add android:focusable="false" for ListView row items to make ListView Clikable. Because the views in the row of ListView gain the focus so ListView is not focusable. So, in your case you can add android:focusable="false" to the TextViews of your ListView row.

I had the same symptoms, and it drove me crazy for a while. Adding android:focusable="false" for the list items as suggested above fixed the problem for me.
But the real issue was that I had set android:textIsSelectable="true" for my list items (in response to a Warning generated by Eclipse); setting android:textIsSelectable="false" fixed the problem for me, and I did not need the android:focusable="false" option at all.

The workaround I found avoid the
AdapterView.OnItemClickListener mMessageClickedHandler=new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
};
on the ListView, but exploit the Adapter constructor that takes a Context as parameter:
myCustomAdapter=new MyCustomAdapter(ActivityName.this,...)
Passing ActivityName.this is possible to cast the Context in the adapter's class as ActivityName in a safe way and use its methods working like callbacks:
((ActivityName)context).activityMethod()
Given that the getView() method of the Adapter class has a position parameter, is possible to pass this value to the activityMethod(int position) in order to know which list item has been pressed into the Activity where the ListView is.

Another solution.
if you have many child-control,and its to trouble to add android:focusable="false" to every child-control,you can add android:descendantFocusability="blocksDescendants" to its parent-control.try it.

I struggled with this for a while - none of the provided solutions worked for me. In the end I found that having a call to getListView() in my onViewCreated() method did the trick, although I have no idea why. This is for a Fragment rather than an Activity; not sure if this makes any difference.
public class NewsListFragment extends ListFragment {
private ListView listView;
...
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
newsListView = getListView();
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
// this now works as expected
}
}

I was also struggling with this issue and none of the suggested solutions worked. My problem was that I did an override for onViewCreated but didn't call super.onViewCreated(view, savedInstanceState);. Hopefully this will help someone else so they don't spend hours trying to figure out what's going on.

I struggled as I by mistake put android:inputType="textCapWords" with the textbox after removing it it is fixed

Only the line below worked for me:
android:descendantFocusability="blocksDescendants"
The whole list_view_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<!--android:focusableInTouchMode="false"-->
<!--android:focusable="false"-->
<!--android:clickable="false"-->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:descendantFocusability="blocksDescendants"
android:layout_height="wrap_content">
<CheckBox
android:id="#+id/checkBox_list_view_checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/checkBox_list_view_textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
The above is to be used in getView like:
convertView=LayoutInflater.from(getContext())
.inflate(R.layout.list_view_item, parent, false);
`

thanks in advance.....

hi nirav to get a onItem click of list u have to write onclickListener that i not found in your code try with that.

Instead of setting the clikclistener lv.setOnItemClickListener(new OnItemClickListener()
, can you use the override the method,
protected void onListItemClick(ListView l, View v, int position, long id) which is provided by the ListActivity

try this, its working for me..
public void onItemClick(AdapterView<?> parent,
View view1, int position, long id) {
// The action to be taken when item is clicked
}

SimpleAdapter adapter = new SimpleAdapter(this,
groupData,
R.layout.listitem,
new String[] {"name" , "id"},
new int[]{ R.id.txtItemName, R.id.txtid} );
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3){
//u get positon of list item from arg2
}
});

How to let a user add and remove items to a ListView?

I am trying to make it so that when a user clicks a button, it pops up a dialog with an EditText and an OK Button. When the user completes, the dialog, it should add the item they just typed in to the ListView. How do I do this?
I will need a large code example; this is my first application.

You'll want to follow the official notepad tutorial example. It's very comprehensive. It does 95% of what you want to do.
http://developer.android.com/resources/tutorials/notepad/index.html

Well here is a sample code. There is a button to add text in list and long press on list item will remove it.
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Add Item" />
<ListView
android:id="#+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
dialog_layout.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="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/edit_box"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:inputType="text" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"

<Button
android:id="#+id/button_ok"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="OK" />
<Button
android:id="#+id/button_cancel"
android:layout_width="0dp"
android:layout_height="wrap_content"
