Set Button Onclick In Listview Android

i have a listView with list item like this. i want to set an action at button 'Edit' and 'Delete'. this is my code. listitem.xml <

Solution 1:

Try to use BaseAdapter Instead of ListAdapter it will be easier

Here i'm giving sample code you can implement like this in your code,

publicclassBaseAdapContactextendsBaseAdapter {

List<String> liName;
Context con;

publicBaseAdapContact(List<String> liName, Context con) {
    this.liName = liName;
    this.con = con;
}

@OverridepublicintgetCount() { // TODO Auto-generated method stubreturn liName.size();
}

@Overridepublic Object getItem(int position) { 

    returnnull; 
}

@OverridepubliclonggetItemId(int position) { 

    return0; 
}

@Overridepublic View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflaterlif= (LayoutInflater) con
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = lif.inflate(R.layout.list_view, null);

    TextViewtxt_Name= (TextView) convertView.findViewById(R.id.txtName);
    Buttonbtn_Call= (Button) convertView.findViewById(R.id.btnCall);

    txt_Name.setText(liName.get(position));

    btn_Call.setOnClickListener(newOnClickListener() {

        @OverridepublicvoidonClick(View v) {

             //Here perform the action you want             
        }

    });

    return convertView;
}

}

Solution 2:

As per my aspect you should initialized your list in setUpView();

list = (ListView) findViewById(R.id.list);

Your app is crash at

  list.invalidateViews();
  list.setAdapter(adapter);

in onPostExecute(Void result) at this line list==null

Solution 3:

Where is your list adapter???

You should set onClickListner on a button inside your list adapter

Solution 4:

you should use interface to listen Click Event.

Here is example,

First, you need to create a interface in adapter.

publicinterfaceonListItemClickListener{
    voidonEditClick();
    voidonDeleteClick();
}

And then implement onListItemClickListener in your registerItem activity. It will need to implement two methods in your activity.

in click event from your adapter, for ex

btn_edit.setOnClickListener(newOnClickListener() {

    @OverridepublicvoidonClick(View v) {

         //you will contain Context from your parent activity//cast your context to listener coz it implement that listeneronListItemClickListenerlistener= (onListItemClickListener) mContext;

         // you can add parameter in method
         listener.onEditClick();
         //Done this will call your method in your activity.
    } 

}); 

Hope this will help you.
