How to get object value from listview adapter position

Question

How to get value from adapter position, i have code in below:

CategoriesXmlParser categoryXmlParser = new CategoriesXmlParser();
List<HashMap<String, Object>> categories = null;

try {
  categories = categoryXmlParser.parse(reader);
} catch (Exception e) {
  Log.d("Exception", e.toString());
}

String[] from = { "name", "image" };
int[] to = { R.id.nama_category, R.id.logo_category };

final SimpleAdapter adapter = new SimpleAdapter(getBaseContext(),
                    categories, R.layout.per_item_category, from, to);

mListView.setOnItemClickListener(new OnItemClickListener() {
  public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
    Object obj = mListView.getAdapter().getItem(position);
    String value = obj.toString();
    Log.d("MyLog", "Value is: "+value);
    String name = // how code to get name value.
  }
});

If I look log it on logcat in the MyLog I get as:

Value is: {position=12, image_path=http://192.168.103.121/xml/icon.png, link=http://192.168.103.121/xml/category.php?kat_id=13, name=Category 13}

So my question, I want to get value from name and stored to variable String name, I want to get just "Category 13" in String name. Because I want to passing it to another activity.

Well, what object type do you fill your adapter with? You can simply cast the result of getItem() to that and then use whatever accessors you implemented to retrieve the value for the name field. – Kerns

Answer 1

Looks like you made ​​the object with hashmap, such blablabla.put("name", "value")?? If yes. Try this:

mListView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
        Object obj = mListView.getAdapter().getItem(position);
        String value = obj.toString();
        Log.d("MyLog", "Value is: "+value);
        String name = // how code to get name value.
    }
});

Change to:

mListView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        HashMap<String, Object> obj = (HashMap<String, Object>) adapter.getItem(position);
            String name = (String) obj.get("name");
            Log.d("Yourtag", name);
    }
});

listID.setOnItemClickListener(new AdapterView.OnItemClickListener() 
                {

                    @Override
                    public void onItemClick(AdapterView<?> parent, View v,
                            int position, long id) {
                        // TODO Auto-generated method stub

                        Object obj=listID.getAdapter().getItem(position);
                        String str=obj.toString();

                    Toast.makeText(MainActivity.this, "Item is= "+str, Toast.LENGTH_LONG).show();
                    }
                });

You can also get the adapter data via AdapterView<?> parent

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    //setHasOptionsMenu(true);
    listView.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

            final Filedata mnotes = (Filedata) parent
                    .getItemAtPosition(position);
           Toast.makeText(getActivity(), Filedata.getName(),Toast.LENGTH_SHORT).show();
});
}

This is what i did:-

lvHomePage.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                   @Override
                   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                       Transaction selectedFromList =(Transaction)parent.getAdapter().getItem(position);
                       Log.d("val:",selectedFromList.getDate());
                       Log.d("val:",selectedFromList.getMobile_no());
                   }
               });

HashMap<String, Object> sdsa = (HashMap<String, Object>) adapter.getItem(position); Log.e("IndentNo", (String) sdsa.get("IndentNo")); Log.e("IndentId", (String) sdsa.get("IndentId"));

                }
