我正在尝试为我的一个 View ( fragment 内)内的按钮 (R.id.buy_button) 设置/覆盖 onclick 方法。应用程序不返回错误。但是它不会触发 onclick 方法。我不确定是我的实现有误还是我的按钮配置不正确。任何帮助/意见/指导将不胜感激。

我的 onCreateView 在这里:

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

    View view = inflater.inflate(R.layout.list_item, container, false);
    Button b = (Button) view.findViewById(R.id.buy_button);
    b.setOnClickListener(this);

    return inflater.inflate(R.layout.fragment_item_list, container, false);
}

我的整个 fragment 代码:

public static class AlbumsFragment extends ListFragment implements View.OnClickListener {
        private static final String ARG_SECTION_NUMBER = "section_number";

        public AlbumsFragment() {
        }

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

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

            ListView listView = getListView();
            List<Album> albums = null;

            albums = Album.listAll(Album.class);
            Log.i("ALBUMS", albums.toString());
            ArrayAdapter<Album> adapter =
                    new ArrayAdapter<Album>(getActivity(), R.layout.list_item, R.id.textView,  albums);
            if (!albums.equals("")) {
                listView.setAdapter(adapter);
            }
        }

        @Override
        public void onAttach(Activity activity) {
            super.onAttach(activity);
            ((MainActivity) activity).onSectionAttached(
                    getArguments().getInt(ARG_SECTION_NUMBER));
        }

        @Override
        public void onDestroy() {
            super.onDestroy();
        }

        @Override
        public void onDetach() {
            super.onDetach();
        }

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

            View view = inflater.inflate(R.layout.list_item, container, false);
            Button b = (Button) view.findViewById(R.id.buy_button);
            b.setOnClickListener(this);

            return inflater.inflate(R.layout.fragment_item_list, container, false);
        }

        public void gotoPurchaseWeb() {
            Context context = getActivity().getApplicationContext();
            Intent intent = new Intent(context, PurchaseSong.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(intent);
        }

        public static AlbumsFragment newInstance(int sectionNumber) {
            AlbumsFragment fragment = new AlbumsFragment();
            Bundle args = new Bundle();
            args.putInt(ARG_SECTION_NUMBER, sectionNumber);
            fragment.setArguments(args);

            return fragment;
        }

        @Override
        public void onClick(View v) {
            switch (v.getId()) {
                case R.id.buy_button:
                    Context context = getActivity().getApplicationContext();
                    Intent intent = new Intent(context, PurchaseSong.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(intent);
                    break;
            }
        }
    }

最佳答案

您应该在 Fragment 内的 onCreateView 回调函数中返回您的 View ，而不是返回 View 的新膨胀实例。

return inflater.inflate(R.layout.fragment_item_list, container, false);

改为使用:

return view;

关于android - fragment 内的按钮 onclick 不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23490880/
