android – Get listview item position on button click

Questions:

This is my listview click event:

 lv1.setOnItemClickListener(new OnItemClickListener() {
       @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
                Object o = lv1.getItemAtPosition(position);
                ItemDetails obj_itemDetails = (ItemDetails)o;
                Toast.makeText(ListViewImagesActivity.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();

        }  
 });

And this is my button click event:

btnNxt = (Button) findViewById(R.id.btnNext);
 btnNxt.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View arg0) {
  //Here I need to get that position
});

Now I need to get the position of the clicked listview item..I have declared postion globally but that always gives me position 1.

Can anyone say me how do I get the positon ?

How to&Answers:

do you execute this

    btnNxt = (Button) findViewById(R.id.btnNext);
 btnNxt.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View arg0) {
  //Here I need to get that position
});

inside the getView method?
if so it’s very easy

     btnNxt = (Button) findViewById(R.id.btnNext);
     btnNxt.setTag(position);
     btnNxt.setOnClickListener(new OnClickListener() {
     @Override
     public void onClick(View arg0) {
      int position=(Integer)arg0.getTag();
    });

Answer:

I know I’m bit late with the answer, but what about this:

private OnClickListener myButtonClickListener = new OnClickListener() {
@Override
public void onClick(View v) {
    View parentRow = (View) v.getParent();
    ListView listView = (ListView) parentRow.getParent();
    final int position = listView.getPositionForView(parentRow);
  }
};

in this case you don’t need to set tags and so on.

Answer:

If you are using ViewHolder make sure you use setTag() like this.

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


        if (convertView == null) {
            holder = new ViewHolder();
            convertView = mLayoutInflater.inflate(R.layout.custom_row, parent, false);
            holder.btnNxt = (Button) convertView.findViewById(R.id.btnNext);
            holder.btnNxt.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
                    int position=(Integer)arg0.getTag();
                });
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
          holder.btnNxt.setTag(position);   // <---- setTag() here 

            return convertView;
        }

        private class ViewHolder {
            Button btnNxt;
        }
    }

If you setTag() before your setOnClickListener() line, you will have problem when you scroll your listview.

Answer:

declare a global variable and in onItemClick() method of lisview set the view position as variable’s value.
now use same variable in click method of button.

int global_position =0; // your global variable 

 lv1.setOnItemClickListener(new OnItemClickListener() {
       @Override
            public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
               global_position =position;
        }  
 });

btnNxt = (Button) findViewById(R.id.btnNext);
 btnNxt.setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View arg0) {
    Toast.makeText(<context>,""+global_position,500).show();
});

Answer:

// use “top” to get listview items top position

// Listview items top position

    int top;
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View lView, final int pos, long id) {
            top = lView.getTop();
            if (top < 1) top = 1;
        }
    });

// Or
// Listview items top position Under CustomAdapter’s getView method

    int top;
    final View finalConvertView = convertView;
    convertView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            top = finalConvertView.getTop();

            if (top < 1) top = 1;

        }
    });
