listview with button

Question

Possible Duplicate:
Handling button event in each row of Listview issue

I am working on an android app. I am supposed to add a button in each row of ListView and when I click any button I need the button should be removed. However when I do so, button is removed but some other buttons in other positions also removed. Furthermore when i scroll down and up the ListView these buttons which I clicked and removed again appear in the list. Could you please show me an exact solution or a completed piece of code? Thank you...

public View getView(final int position, View convertView, ViewGroup parent) {

        if(convertView == null){
            // LayoutInflater class is used to instantiate layout XML file into its corresponding View objects.
            LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
            convertView = layoutInflater.inflate(R.layout.listxml, null);
        }


        rawTextView = (TextView) convertView.findViewById(R.id.textView1);
        rawTextView.setText("Text "+innerClassBookArray[position]);

        final LinearLayout lnr=(LinearLayout)convertView.findViewById(R.id.layoutforbtn);

         final Button btn = new Button(getBaseContext()); 
            btn.setText("MyButton"); 
            btn.setId(position);
            lnr.addView(btn); 

           btn.setOnClickListener(myOnBtnClickListener);

        return convertView;
    }   
      private OnClickListener myOnBtnClickListener = new OnClickListener() {
            @Override
            public void onClick(View v) {
                final int posit = bookListView.getPositionForView((View) v.getParent());
                Toast.makeText(getApplicationContext(), Integer.toString(posit), Toast.LENGTH_LONG).show();

            }
        };

use holder class and declare the view in it. – AkashG Jul 09 '12 at 08:21 — AkashG, Jul 09 '12 at 08:21

You can do it like this make a Array-list where every element as "0" (Arraylist<String> my=new ArrayList<String>(); Size of Arraylist should be according to the size of column in list view)and on button click set the "1" at the position of like my.set(position,"1"); and then notify the list view. also see if condition in the below code for example

 public View getView(final int position, View convertView, ViewGroup parent) {

            if(convertView == null){
                // LayoutInflater class is used to instantiate layout XML file into its corresponding View objects.
                LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
                convertView = layoutInflater.inflate(R.layout.listxml, null);
            }


            rawTextView = (TextView) convertView.findViewById(R.id.textView1);
            rawTextView.setText("Text "+innerClassBookArray[position]);
  Button button =(Button)findViewById(R.id.yourid);

      if(my.get(position).equals("1")){
    button.setVisiblity(View.INVISIBLE);
    }
            final LinearLayout lnr=(LinearLayout)convertView.findViewById(R.id.layoutforbtn);


               btn.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {

    my.set(position,"1");
    ((BaseAdapter)yourActivity.this.lv.getAdapter()).notifyDataSetChanged();
                }
            });


            return convertView;
        }   
I think this will definitely help you any question ask me

Here is the easy and nice tutorial for you. In this code when on click event try hiding the button

Btn01.setOnClickListener(new OnClickListener(){

 public void onClick(View v) {

//Toast.makeText(SearchUser.this, "Button 1 "+listview_arr[position], Toast.LENGTH_SHORT).show();
Btn01.setvisibility(view.Gone);
}
});

Try like this. Hope its helpful to you. Good Luck

i have already tried something like that. But some of other buttons also disappered and furthermore when i scroll down or up the list the buttons again appeared :( – Emilla Jul 09 '12 at 08:39
I am sure if you try that one you will definitely get your result. if not after button hideen call list.notifyDataSetChanged(); and also you must extends listactivity – Ram kiran Pachigolla Jul 09 '12 at 12:09
