OnItemClickListener on a ListView inside a Fragmen

问题:

EDIT: SOLVED. If there's anything focusable in the XML of the items, it will break the touch of the list, in other words, android:focusable=false to all the checkboxes, switches or anything like that of ur list. And done =)

Ok so, here's my problem.

I wrote a app that uses tabs and fragments, and it all goes the way I want except for the thing that when I try to capture a onItemClick on a listView it does not even mark the row as touched/pressed/selected.

I've been reading a little bit about and many people have the same issue, but I did not found any responses that helped me at all.

I don't want to implement a ListFragment, in fact I don't even know how/why I should, and since all my code is already working, I don't know if implementing one will give me much more work to do, so, here it is:

Is it possible to implement a listener for a click on a listView, inside a fragment? and if it is, HOW?

PD: minSDK=14, tatgetSDK=15

Here's a code snippet that'll do what you want.

ListView lv;

//code to get the listView instance using findViewByID etc

lv.setOnItemClickListener(new OnItemClickListener()
{
    @Override public void onItemClick(AdapterView<?> arg0, View arg1,int position, long arg3)
    { 
        Toast.makeText(EnclosingActivity.this, "Stop Clicking me", Toast.LENGTH_SHORT).show();
    }
});

People usually trip on this, see if you have got this covered:

All clicks and call backs (eg: the menu/actionbar callbacks) are sent to the activity the fragment is bound to, so they must be in the activity class and not the fragment class.

Just put

android:focusable="false"
android:clickable="false"

in layout. For all textviews,buttons etc.

Two awesome solutions were this, if your extending ListFragment from a fragment, know that mListView.setOnItemClickListener wont be called before your activity is created, As @dheeraj-bhaskar implied. This solution ensured it is set when activity has been created

@Override
    public void onActivityCreated(Bundle savedInstanceState)
    {
        super.onActivityCreated(savedInstanceState);
        mListView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long rowId) {
                // Do the onItemClick action

                Log.d("ROWSELECT", "" + rowId);
            }
        });
    }

While looking at the source code for ListFragment, I came across this

    public class ListFragment extends Fragment {
        ...........................................
     ................................................

        final private AdapterView.OnItemClickListener mOnClickListener
                = new AdapterView.OnItemClickListener() 
{
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) 
{
                onListItemClick((ListView)parent, v, position, id);
            }
        };
       .................................................................
    ........................................................................

    public void onListItemClick(ListView l, View v, int position, long id) 
{
        }
}

An onItemClickListener object is attached and it calls onListItemClick() As such the other similar solution, which works in the exact same way is to override onListItemClick()

 @Override
        public void onListItemClick(ListView l, View v, int position, long rowId) {
            super.onListItemClick(l, v, position, id);
           // Do the onItemClick action

                    Log.d("ROWSELECT", "" + rowId);
        }

If you want to pass data from fragment to any activity on Listview click then you can modify your code like...

class HistoryFragment extends Fragment {  ListView historyListView;
public HistoryFragment() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View v= inflater.inflate(R.layout.fragment_history, container, false);
    historyListView= (ListView) v.findViewById(R.id.historyDataListView);

    sendRequest();  //it is my meathod to load the listview and set the adapter
    return  v;
}

public void onStart() {
    super.onStart();
    historyListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            Intent intent=new Intent(getActivity(), DisplayDetails.class);

            intent.putExtra("text", historyListView.getItemAtPosition((int) l).toString());
            startActivity(intent);
          //  Toast.makeText(getActivity(),"Hello.. "+historyListView.getItemAtPosition((int) l).toString(),Toast.LENGTH_LONG).show();
        }
    });
}}

Here is an overview of the workflow, create your ListView and it's corresponding Adapter(used to map your underlying data to the items in the ListView), set the adapter to the ListView, and then add an OnItemClickListener to it.

the button will affect the listener, try avoid using button and re compile, it should work
