I.e. instead of just looping through one array element at a time, but to loop through selected pairs instead (e.g. 3 elements, and then to do something to those 3). there are many ways to do it. one would be $arr = array(1,2,3,4,5,6,7,8,9); $new = array_chunk($arr,3); foreach ($new as $chunk) { print_r($chunk);// 3 elements to … Read more
In your activity, where you defined your listview you write listview.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?>adapter,View v, int position){ ItemClicked item = adapter.getItemAtPosition(position); Intent intent = new Intent(Activity.this,destinationActivity.class); //based on item add info to intent startActivity(intent); } }); in your adapter’s getItem you write public ItemClicked getItem(int position){ return items.get(position); }

That’s really all there is to it. There is nothing unpredictable about either collection, although … Read more
