Can not click on listView

[Hardik Trivedi]

Hi,

I am facing a strange problem.I made a custom array Adapter which displays thing in list view.This works fine but when I click on list items. I am not able to click them.

The following is a bit of a code which I did for that.

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.list_mail_1);
        
        mailList = new ArrayList<Mails>();
        this.m_adapter = new MailAdapter(this, R.layout.list_mail_2, mailList);
        setListAdapter(this.m_adapter);
        getListView().setClickable(true);
        getListView().setFocusable(true);
        getListView().setFocusableInTouchMode(true);
        getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);

@Override
    protected void onListItemClick(ListView l,View v,int pos,long id)
    {
    	super.onListItemClick(l, v, pos, id);
    	Mails mail=new Mails();
    	mail=mailList.get(pos);
    	Log.v(TAG,":::::::::"+mail.getSub());
    }

Sorry I am not giving the full code,because it will become clumsy.

please help..

hi try to use setOnItemClickListener event
for example---

dgame.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {

---------------------
}
});

Do you have focusable items in your rows of your ListView?

Since you have used Choice Mode, Use setOnItemSelectedListener

ArrayAdapter works fine.
There is some other problem in setting the listener.
