问题

I have added arraylist in arrayadapter which contains objects each consists of two elements/items, I have successfully set that adapter for setListAdapter, now i want to get those items in setOnItemClickListener of listview.

here is my code

   TweetListAdaptor adaptor = new TweetListAdaptor(this,R.layout.list_item, tweets);       
   setListAdapter(adaptor); 
   ListView lv = getListView();
   lv.setTextFilterEnabled(true);
   lv.setOnItemClickListener(new OnItemClickListener() 
   {
   public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
   {
     //here i want to get the items             
   }
 });

回答1:

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    int color = parent.getAdapter().getItem(position);
}

回答2:

public void onItemClick(AdapterView<?> parent, View view,int position, long id){
    something = tweets[position];
}

You want to get the items and do what with them?

For example, you can make a Toast message like this.

public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
    {
        Toast.makeText(getApplicationContext(), tweets[position], Toast.LENGTH_SHORT).show();

    }

Hope this helps.

and if you have the listview ready with all datas and want get a value of a objet only use:

ViewGroup row = (ViewGroup) listprod.getChildAt(0);
TextView tvTest = (TextView) row.findViewById(R.id.textnomprod);

Where my listview is "listprod" and i want get the value in the position 0, where textnomprod is my objet and im saving in my variable tvTest

回答5:

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {
        Windows clickedObject = adapter.get(position);
    }
}

Consider in the example above,

object used in the listview is named Windows,
the object of the item clicked in the listview is named clickedObject,
the arraylist used is called adapter.

Also, make sure to prefix your ArrayList with final.

I solved this problem by using its adapter that was set to it.

TweetListAdaptor adaptor = new TweetListAdaptor(this,R.layout.list_item, tweets);       
setListAdapter(adaptor); 
ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() 
{
    public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
   {    
        //here i want to get the items  
        adaptor.getItem(position);   // this is your object
    }
});

Just keep in mind that the adapter must be initialized and set to the ListView.

In this way, you can access the properties of the object you want.

getListView().getItemAtPosition(position) will return an Object in your TweetListAdaptor
