Question

我正在尝试根据Parse的信息在文本视图中显示文本。例如，在这种情况下，我试图显示用户的活动名称。以下是代码

 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 {

            }
            }
        });

布局

<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>

Answer 1

我不确定我是否理解你的问题。您是否尝试过以这种方式设置TextView文本？

text.setText("ActivityName");

Answer 2

那样的东西？

text.setText(userlistactivityname.get(0).get("ActivityName"))

在Textview上显示Parse的信息
