Question

我有一个parse.com应用程序，当我点击列表项时，我想要它，它会将文本输出，当我再次单击它时，它会将文本恢复正常。有关如何做到这一点的任何想法？谢谢！

public class AgendaActivity extends Activity {

    //First Call ArrayList
    private ArrayList<String> assignments;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        assignments = new ArrayList<String>();
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, assignments);
        setListAdapter(adapter);

        agendaList();
    }

   //Query List
    public void agendaList(){
        ParseQuery<ParseObject> query = ParseQuery.getQuery("Agenda");
        query.whereEqualTo("userId", ParseUser.getCurrentUser());
        query.findInBackground(new FindCallback<ParseObject>() {
            //Show up in list
            @Override
            public void done(List<ParseObject> parseObjects, ParseException e) {
                if (e == null) {
                    // If there are results, update the list of posts
                    // and notify the adapter
                    assignments.clear();
                    //Gets all data from parse
                    for (ParseObject post : parseObjects) {
                        assignments.add(post.getString("name") + "\n" + "Date Due: " +
                                post.getString("dueDate") + "\n" + "Class: " + post.getString("class"));

                    }

                    ((ArrayAdapter<String>)getListAdapter()).notifyDataSetChanged();
                } else {
                    //Error Logging
                    Log.d("Post retrieval", "Error: " + e.getMessage());
                }
            }
        });
    }

使用它！

tv是textView。

tv.setPaintFlags(tv.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG); //this strikes through the text

另外，对于非打击使用此，

tv.setPaintFlags( tv.getPaintFlags() & (~ Paint.STRIKE_THRU_TEXT_FLAG));

在适配器类的getView方法中使用它。

另外，建议您可以浏览ParseQueryAdapter列出从Parse获取的对象。
