When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?

Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.

The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

'android.R.id.list' that is not a ListView class in ListFragment

I am new to android development. I have created a List View for displaying items in custom formats. I have given code below that I've used in eclipse. But I'm receiving an error while running the application, "Content has view with id attribute 'android.R.id.list' that is not a ListView class in ListFragment".
This is Activity
import android.app.ListFragment;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class CalllogActivity extends ListFragment implements AdapterView.OnItemClickListener{
private CLAdapter adapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_list, container, false);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(), R.array.CallLogs, R.layout.layout_calllogs);
ListView lstDetails= (ListView) getView().findViewById(R.id.lstDtls);
adapter=new CLAdapter(this);
lstDetails.setAdapter(adapter);
lstDetails.setOnItemClickListener(this);
}
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i,
long l) {
Toast.makeText(getActivity(), "Item " + i, Toast.LENGTH_SHORT).show();
}
class CLAdapter extends BaseAdapter{
private Context context;
String[] CallLogNames;
String[] CallNo;
int[] images;
String[] CallDateTime;
public CLAdapter(Context context){
this.context=context;
CallLogNames = context.getResources().getStringArray(R.array.CallLogs);
}
public CLAdapter(CalllogActivity calllogActivity) {
CallLogNames = context.getResources().getStringArray(R.array.CallLogs);
}
#Override
public int getCount() {
return CallLogNames.length;
}
#Override
public Object getItem(int position) {
return CallLogNames[position];
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row=null;
if(convertView==null)
{
LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.layout_calllogs, parent, false);
}
else
{
row=convertView;
}
TextView txtName=(TextView) row.findViewById(R.id.txtName);
ImageView imgPhoto=(ImageView) row.findViewById(R.id.imgContact);
TextView txtNo = (TextView) row.findViewById(R.id.txtNo);
TextView txtDateTime = (TextView)row.findViewById(R.id.txtDateTime);
txtName.setText(CallLogNames[position]);
//txtNo.setText(CallLogNames[position]);
//txtDateTime.setText(CallLogNames[position]);
//imgPhoto.setImageResource(images[position]);
return row;
}
}
}
This is the Fragment XML Code
<?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" >
<ListView
android:id="#+id/lstDtls"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
</LinearLayout>
This is the custom layout I've created for showing in the List
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imgContact"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:adjustViewBounds="true"
android:maxHeight="60dp"
android:maxWidth="60dp"
android:src="#drawable/unknown_contact" />
<TextView
android:id="#+id/txtName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginLeft="12dp"
android:layout_marginTop="10dp"
android:layout_toRightOf="#+id/imgContact"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/txtNo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imgContact"
android:layout_alignRight="#+id/txtName"
android:layout_marginBottom="5dp"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/txtDateTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/txtName"
android:layout_alignBottom="#+id/txtName"
android:layout_alignParentRight="true"
android:layout_marginRight="18dp"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>

When you want to use ListFragment or ListActivity list in your layout has to use predefined id:
android:id="#android:id/list"
In your code you can retrieve this list by using
ListView listview = (ListView)findViewById(android.R.id.list);
ListFragment and ListActivity have hard coded this value and do not work if they cannot find list to use.

Try to change Id of listView
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
then use R.id.list not android.R.id.list

To add onto this, it's worth noting that in the ListFragment spec it mentions that the listview named 'list' must have either the sibling android.R.id.empty, or not be empty. My issue was that the listview was both empty and didn't have the empty sibling.
The fix was to add a textview named empty,
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/list">
</ListView>
<TextView
android:id="#android:id/empty"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TextView>

Image not displayed in listview

Went through many demos and was not able to figure out how to get the imageview work in list view.
Tried the code however the image is not visible in listview. Other details are working fine in the list view
Please help.
Following is the code
The mainactivity has tabhost. Under the second tab listview is present.
listdata is the data that i need in the list.
MyBaseAdapter is for the adapter needed to load data in listview.

Kindly help me out.
Thanks in anticipation.

Can you please paste your activity_main.xml? Moreso, it is preferable you use actionbar tabs.

Just changed position of layout and it stopped working
Clean and rebuild. Likely your resource ids in binary XML files and R.java are out of sync.
Now that you've included logcat, java.lang.ClassCastException: android.widget.ImageView cannot be cast to android.widget.TextView in detail() are also indicative of this - the resource ids you're passing to the method are valid TextViews but at least in one case it is referring to an ImageView in binary XML.

the mistake is in MyBaseAdapter.java
simple mistake, parameters mismatched.
insted of
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(resId);
iv.setImageResource(resId);
return iv;
}
we need to change it to
private ImageView idetail(View v,int resId,int icon)
{
ImageView iv=(ImageView) v.findViewById(R.id.icon);
iv.setImageResource(icon);
return iv;
}

In ProductAdapter, the getCount() method returns the number of items owned by the Adapter associated with this ListView. So, it should return the maximum number of items that the listview will display i.e. the size of the list you are using as a data source : mproductList.size()
The getView() method is not getting called because this function is returning 0 in your code.

Only took a fast glance, but getCount() should return the number of items
in the adapter, and therefore mproductList.size()
