如何从自定义适配器数据的ListView?

更新时间:2022-10-19 13:43:40

onItemClick 您可以使用适配器视图参数

  NextRdv项目=(NextRdv)parent.getItemAtPosition(位置)

here is my problem :

I created a custom adapter for my ListView and I get information out of a List that I give to that adapter in order to let him fulfill my ListView. He does everything correctly. Now I'd like to implement an OnItemClickListener and to get the data from it. But in that list I have 4 TextViews ...

How can I retrieve the data ?

I already know how to get the id and position since I display them in a Toast.

Thanks a lot for your help !

Here is the custom Adapter :

public class NextRdvAdapter extends ArrayAdapter<NextRdv> {
private List<NextRdv> listNextRdv = new ArrayList<NextRdv>(); 
private Context context; 

public NextRdvAdapter(List<NextRdv> nextRdvList, Context ctx) {
    super(ctx, R.layout.list_next_rdv, nextRdvList);
    this.listNextRdv = nextRdvList; 
    this.context = ctx;
} 

public View getView(int position, View convertView, ViewGroup parent) {

    if (convertView == null) { // This a new view we inflate the new layout 
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        convertView = inflater.inflate(R.layout.list_next_rdv, parent, false); 
        } // Now we can fill the layout with the right values 

    TextView tvTimeStart = (TextView) convertView.findViewById(R.id.next_time_start); 
    TextView tvTimeEnd = (TextView) convertView.findViewById(R.id.next_time_end); 
    TextView tvEnterprise = (TextView) convertView.findViewById(R.id.next_enterprise_name); 
    TextView tvAddress = (TextView) convertView.findViewById(R.id.next_address); 
    NextRdv rdv = listNextRdv.get(position); 

    tvTimeStart.setText(rdv.getStartTime());
    tvTimeEnd.setText(rdv.getEndTime());
    tvEnterprise.setText(rdv.getEnterprise());
    tvAddress.setText(rdv.getAddress());


    return convertView; 
    }
}

Here is my Fragment that posess the ListView :

public class HomeFragment extends Fragment implements OnItemClickListener{

float density;

//Everything you need about this rdv
private ListView lvThisRdv;
private List<NextRdv> listThisRdv = new ArrayList<NextRdv>();
private NextRdvAdapter ThisRdvAdapter;  
private NextRdvListBouchon thisBouchon;

//Everything you need about next rdv
private ListView lvNextRdv;
private List<NextRdv> listNextRdv = new ArrayList<NextRdv>();
private NextRdvAdapter nextRdvAdapter;  
private NextRdvListBouchon bouchon;

public HomeFragment(){}

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

    View rootView = inflater.inflate(R.layout.fragment_home, container, false);


    lvThisRdv = (ListView)rootView.findViewById(R.id.listView_this_RDV);
    thisBouchon = new NextRdvListBouchon();
    listThisRdv = thisBouchon.getBouchonInc();
    ThisRdvAdapter = new NextRdvAdapter(listThisRdv, getActivity());
    lvThisRdv.setAdapter(ThisRdvAdapter);

    //Displaying the list of the next meetings
    lvNextRdv = (ListView)rootView.findViewById(R.id.listView_next_RDV);

    //Get test data
    bouchon = new NextRdvListBouchon();
    listNextRdv = bouchon.getBouchon();

    nextRdvAdapter = new NextRdvAdapter(listNextRdv, getActivity());
    lvNextRdv.setAdapter(nextRdvAdapter);

    lvNextRdv.setOnItemClickListener(new OnItemClickListener() {

          @Override
          public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {

              //
              Toast toast = Toast.makeText(getActivity(), "Pos : " +position+ " / id : " + id, Toast.LENGTH_SHORT);
              toast.show();
          }

    });

    return rootView;
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
        long id) {
}
}

inside onItemClick you can use the AdapterView argument,

NextRdv item = (NextRdv) parent.getItemAtPosition(position)
