问题描述

我在 listfragment 中有一个带有自定义适配器的列表视图,并且还为列表视图设置了 onclicklistner.但是 Onclicklistner 不起作用.

I have a listview with custom adapter in listfragment and also set onclicklistner for listview. But Onclicklistner does not work.

这是我的代码:

public class BasicFragment extends ListFragment {

ListView lv;
MyCustomAdapter adapter;

@Override
public void onCreate(Bundle si) {
    super.onCreate(si);
}

@Override
public void onActivityCreated(Bundle b) {
    super.onActivityCreated(b);
}

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

    View view = inflater.inflate(R.layout.fragment_basic, container, false);
    lv = (ListView) view.findViewById(android.R.id.list);
    FetchedData DT = FetchedData.StaticDataTransfer();
    RecepiesProperties[] AryObjaz = DT.getData();
    getdata(AryObjaz);
    adapter = new MyCustomAdapter(getActivity(), R.layout.listview_layout,
            Dataset);
    lv.setAdapter(adapter);

    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            Toast t = Toast.makeText(getActivity(), "Message",
                    Toast.LENGTH_SHORT);
            t.show();
        }
    });

    return view;
}}

MyCustomAdapter.java

MyCustomAdapter.java

public class MyCustomAdapter extends ArrayAdapter<Recipes> {

Context context;
int layoutResourceId;
Recipes data[] = null;
Typeface typeface;
public ImageLoader imageLoader;

public MyCustomAdapter(Context context, int textViewResourceId,
        Recipes[] dataset) {
    super(context, textViewResourceId, dataset);
    this.layoutResourceId = textViewResourceId;
    this.context = context;
    this.data = dataset;
    imageLoader = new ImageLoader(context.getApplicationContext());
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;

    LayoutInflater inflater = ((Activity) context).getLayoutInflater();
    row = inflater.inflate(layoutResourceId, parent, false);
    RecipesHolder holder = new RecipesHolder();
    holder.imgIcon = (ImageView) row.findViewById(R.id.imageView1);
    holder.txtTitle = (TextView) row.findViewById(R.id.title);
    holder.category = (TextView) row.findViewById(R.id.category);
    holder.source = (TextView) row.findViewById(R.id.source);
    holder.country = (TextView) row.findViewById(R.id.country);
    holder.readytime = (TextView) row.findViewById(R.id.readytime);
    holder.tips = (Button) row.findViewById(R.id.tips);
    holder.fav = (Button) row.findViewById(R.id.fav);

    Recipes ap = data[position];

    imageLoader.DisplayImage(ap.getIMAGENAME240(), holder.imgIcon);
    holder.txtTitle.setText(ap.getNAME());
    holder.category.setText(ap.getCATEGORY());
    holder.source.setText(ap.getSOURCE());
    holder.country.setText(ap.getCOUNTRY());
    holder.readytime.setText(ap.getREADYTIME());

    return row;
}

static class RecipesHolder {
    ImageView imgIcon;
    TextView txtTitle;
    TextView category;
    TextView source;
    TextView country;
    TextView readytime;
    Button tips;
    Button fav;
}}

推荐答案

终于解决了listview中的所有控件(Buttons,textviews)都设置为focusable false的问题.

finally solved the issue when all the controls(Buttons,textviews) in listview set to focusable false.
