Question

您好我是Android新手。我想将我的数据库链接到自动完成文本视图。我可以看到向下滚动列表，我可以从中选择我的文本。但我用来检索所选文本的getText（）方法不起作用。我只得到我在文本框中键入的内容，因此我无法从数据库中检索。请帮助我...给我的代码的片段

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item, getAllCountries());
        final AutoCompleteTextView input_text = (AutoCompleteTextView)findViewById(R.id.Language);
         input_text.setAdapter(adapter);
        Linkify.addLinks(input_text, Linkify.ALL);
        Button button1=(Button)findViewById(R.id.button1);
        final Editable name1=input_text.getText();

.
.
.
public String[] getAllCountries()
    {  
         Cursor cursor = db.rawQuery("SELECT * FROM colors ",null);

                if(cursor.getCount() >0)
        {
            String[] str = new String[cursor.getCount()];
            int i = 0;

            while (cursor.moveToNext())
            {
                 str[i] = cursor.getString(cursor.getColumnIndex("English"));
                 i++;
             }
            return str;

        }
        else
        {
            return new String[] {};
        }
               }

我正在使用此代码创建列表试试这个：

String reciv ; 
    ArrayList<String> first = new ArrayList<String>();

cursor = dbm.columnValueofTable();
            cursor.moveToFirst();
            startManagingCursor(cursor);

            for (int i = 0; i < cursor.getCount(); i++) {

                reciv = cursor.getString(cursor
                        .getColumnIndex("row1"));


                first.add(reciv);

            }

            System.out.println("LIST OF COURSE NAME  " + first);



            final String[] arrayOfStrings;

            arrayOfStrings = first.toArray(new String[first.size()]);


             AutoCompleteTextView  lst = (AutoCompleteTextView  ) dialog
                        .findViewById(R.id.dialog_list);

                lst.setAdapter(new ArrayAdapter<String>(this,
                                 android.R.layout.simple_list_item_1,android.R.id.text1,
                        arrayOfStrings));

在SQL中将SQLite链接到自动完成TextView？
