Anyone please help to solve this problem. I want every time I click the different item resoponse.

CodePudding user response：

Your position lets you identify which item was clicked.

CodePudding user response：

do it like this. i.putExtra("modelkey", list.get(positin).key); because you didn't define the position of value from array-list which are related with the position listview.

    listview.setClickable(true);
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
                Intent i = new Intent(BloodReqActivity.this, BloodReqUpdate.class);
                i.putExtra("modelkey", list.get(position).key);
                view.getContext().startActivity(i);
    
            }
    
        });
