从ListView到TextView（解析）

Question

With support, I have managed to retrieve list and images from parse, however, I want to be able to retrieve string that can be displayed in a textview as oppose to listview because there is no reason using a list when I am just retrieving one item. Furthermore, I have issues with the listview being scrollable on touch, so I guess it would be better if it was just a textview.

Below is the code that retrieves listview, I want to be able to display that information in a textview instead. In this case, I am trying to retrieve information from the ActivityName column of parse for the user that satisfies various conditions set.

ParseQuery<ParseUser> query = ParseUser.getQuery();

        // query.whereEqualTo("ActivityName",userActivitySelectionName);

        query.whereNotEqualTo("objectId", ParseUser.getCurrentUser()
                .getObjectId());
        // users with Gender = currentUser.Looking_Gender
        query.whereEqualTo("Gender", userLookingGender);
        // users with Looking_Gender = currentUser.Gender
        query.whereEqualTo("Looking_Gender", userGender);
        query.setLimit(1);
        query.whereEqualTo("ActivityName", activityName);
        // query.whereGreaterThanOrEqualTo("Age", minimumAge);
        // query.whereLessThanOrEqualTo("Age", maximumAge);
        query.orderByDescending("Name");

        Log.d(Constants.LOG, "");



        query.findInBackground(new FindCallback<ParseUser>() {



            public void done(List<ParseUser> userlistactivityname, ParseException e) {
                if (e == null) {
                    for (int i = 0; i < userlistactivityname.size(); i++) {
                        names.add(userlistactivityname.get(i).get("ActivityName").toString());
                    }
                    usersListActivityname = (ListView) getActivity().findViewById(
                            R.id.userlistactivityname);
                    namesArrayAdapter = new ArrayAdapter<String>(getActivity()
                            .getApplicationContext(), R.layout.user_list_item,
                            names);
                    usersListActivityname.setScrollContainer(false);
                    usersListActivityname.setClickable(false);

                    usersListActivityname.setAdapter(namesArrayAdapter);



                } else {

                }
                }
            });

Below is the XML

<ListView
        android:id="@+id/userlistactivityname"
        android:layout_width="220dp"
        android:layout_height="50dp"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="7dp"
        android:layout_toLeftOf="@+id/imageView2"
        android:divider="@null" >
    </ListView>

Update:

 query2.findInBackground(new FindCallback<ParseUser>() {



            public void done(List<ParseUser> userlistactivityname, ParseException e) {
                if (e == null) {
                    TextView text=(TextView)getActivity().findViewById(R.id.userlistactivityname);
                    text.get("ActivityName").setText();



                } else {

                }
                }
            });

XML

<TextView
        android:id="@+id/userlistactivityname"
        android:layout_width="220dp"
        android:layout_height="50dp"
        android:cacheColorHint="@android:color/transparent"
        android:layout_below="@+id/textView1"
        android:layout_toLeftOf="@+id/imageView2"
        android:divider="@null" >
    </TextView>

Update: textview cannot be cast to android.widget.listview

query2.findInBackground(new FindCallback<ParseUser>() {



            public void done(List<ParseUser> userlistactivityname, ParseException e) {
                if (e == null) {
                     for (int i = 0; i < userlistactivityname.size(); i++) {
                         mUserActivityNameRetrieved = (TextView) getActivity().findViewById(R.id.userlistactivityname);


                         mUserActivityNameRetrieved.setText(userlistactivityname.get(i).get("ActivityName").toString());                     }


                } else {

                }
                }
            });

Answer 1

Just make your ListView a TextView, then when you databind the TextView in Java, called the .setText() method on the TextView. Also, since you're setting the limit of your query to 1, you don't need to order your query. The line query.orderByDescending("Name"); is unnecessary
