Question

每当我点击listview中的项目时，任何人都知道如何在其他片段细节中显示细节项目？以及如何设置它们？谁有这方面的例子？

在listview中只显示： - Nama，gambar1，tipe，mainmuscle，othermuscle，alat，详情评级我要展示的片段： -Nama，gambar1，tipe，mainmuscle，othermuscle，alat，rating， deskripsi，gambar2，gambar3，gambar4

这里是我的代码：

Fragment.java

    public class AbdominalFragment extends Fragment {
    // Log tag
    private static final String TAG = AbdominalFragment.class.getSimpleName();

    // Movies json url
    private static final String url = "http.......";
    private ProgressDialog pDialog;
    private List<Exercise> exerciseList = new ArrayList<Exercise>();
    private ListView listView;
    private CustomListAdapter adapter;

    public AbdominalFragment() {
        // Required empty public constructor
    }

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

    }

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

    private void hidePDialog() {
        if (pDialog != null) {
            pDialog.dismiss();
            pDialog = null;
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.activity_list, container, false);
        // Inflate the layout for this fragment

        final ListView listView = (ListView) rootView.findViewById(R.id.list);
        adapter = new CustomListAdapter(getActivity(), exerciseList);
        listView.setAdapter(adapter);

        pDialog = new ProgressDialog(getActivity());
        // Showing progress dialog before making http request
        pDialog.setMessage("Loading...");
        pDialog.show();

        if(exerciseList.isEmpty()) {
            // Creating volley request obj
            JsonArrayRequest exerciseReq = new JsonArrayRequest(url,
                    new Response.Listener<JSONArray>() {
                        @Override
                        public void onResponse(JSONArray response) {
                            Log.d(TAG, response.toString());
                            hidePDialog();

                            exerciseList.clear();

                            // Parsing json
                            for (int i = 0; i < response.length(); i++) {
                                try {

                                    JSONObject obj = response.getJSONObject(i);
                                    Exercise exercise = new Exercise();
                                    if (obj.getString("tipe").equals("abdominal")) {
                                        exercise.setNama(obj.getString("nama"));
                                        exercise.setGambar1(obj.getString("gambar1"));
                                        exercise.setTipe(obj.getString("tipe"));
                                        exercise.setMainmuscle(obj.getString("mainmuscle"));
                                        exercise.setAlat(obj.getString("alat"));
                                        exercise.setTipe(obj.getString("othermuscle"));
                                        exercise.setRating(obj.getDouble("rating"));


                                        // adding exercise to exercise array
                                        exerciseList.add(exercise);
                                    }
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }

                            }

                            // notifying list adapter about data changes
                            // so that it renders the list view with updated data
                            adapter.notifyDataSetChanged();
                        }
                    }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    VolleyLog.d(TAG, "Error: " + error.getMessage());
                    hidePDialog();

                }
            });

            // Adding request to request queue
            AppController.getInstance().addToRequestQueue(exerciseReq);
        }else{
            hidePDialog();
        }
        return rootView;
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
    }

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

Answer 1

listView.setOnItemClickListener(this);

制作片段implements AdapterView.OnItemClickListener

public class AbdominalFragment extends Fragment implements AdapterView.OnItemClickListener

现在 onClick

@Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
           // Create custom dialog object
            final Dialog dialog = new Dialog(context);
            // Include dialog.xml file
            dialog.setContentView(R.layout.dialog); // layout of your dialog
            // Set dialog title
            dialog.setTitle("Detail");

            // set values for custom dialog components - text, image and button
            TextView text = (TextView) dialog.findViewById(R.id.textDialog);
            text.setText(exerciseList.get(position).getNama());
            // similar add statements for other details 
            dialog.show();

    }

对话框 dialog.xml

的布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >


    <TextView
        android:id="@+id/textDialog"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF"
        android:layout_toRightOf="@+id/imageDialog"/>


</RelativeLayout>

Answer 2

在onCreate()：

中试试

ListView list = (ListView) rootView.findViewById(R.id.listView);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View viewClicked,int position, long id) {
            ArrayList clickedItem = exerciseList.get(position);
            //Here you can hadle your Views....
        }
});

Answer 3

我的建议是使用interface从ListView的OnItemClickListener发送回调到包含AbdominalFragment的活动的回调。

并且根据您的活动可以用细节片段替换AbdominalFragment。

有关与活动的沟通，请参阅以下链接

Answer 4

您可以扩展Listfragment并覆盖onListItemClicked方法。

像这样，

public class AbdominalFragment extends ListFragment {

String[] MONTHS = { "jan", "feb", "march", "april", "may", "june", "july",
        "august", "sep", "octo", "nov", "dec" };

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(
            inflater.getContext(), android.R.layout.simple_list_item_1,
            MONTHS);

    setListAdapter(adapter);

    return super.onCreateView(inflater, container, savedInstanceState);
}

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    // TODO Auto-generated method stub
    super.onListItemClick(l, v, position, id);

    Toast.makeText(getActivity(), "selected month :" + MONTHS[position],
            Toast.LENGTH_LONG).show();
}

}
