Java Can'；使用简单适配器查看数据Sqlite

我有一个显示sqlite表的列表视图。我试着在我的第一次体验中使用Aray适配器，所有的字段都显示出来了，但它只是一团糟。我想让它们看起来像一个有三列的表。我试着从答案中实现代码，这里是我的代码

if (Globals.listoff == null){Globals.listoff = dataSource.getAllproductoff();}
              adapter = new MySimpleAdapter(ViewDataOff.this,dataSource.getAllproductoff() , R.layout.item_list_offeringpro, 
              new String[] { "one", "two","three" },
              new int[] { R.id.edmodul, R.id.edtype,R.id.edtype, R.id.edwinningpro});
              adapter.notifyDataSetChanged();
              setListAdapter(adapter); 

这是我的DBDataSource.java

 public ArrayList<HashMap<String,Object>> getAllproductoff() {
    ArrayList<HashMap<String, Object>> listoff = new ArrayList<HashMap<String, Object>>();
    Cursor cursor = database.query(DBHelper.TABLE_NAME,
            allColumns, null, null, null, null, null);
    cursor.moveToFirst();
    while (!cursor.isAfterLast()) {
        HashMap<String, Object> map1 = new HashMap<String, Object>();
        map1.put("one", cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
        map1.put("two", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DESCRIPTION)));
        map1.put("three", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_PRICE)));
        listoff.add(map1);
      cursor.moveToNext();
    }
    cursor.close();
    return listoff;
}

谢谢你的帮助。。一切都将不胜感激。

更改

光标。moveToNext（）使您的代码如下所示

if (cursor.moveToFirst()) {
    do {
       HashMap<String, Object> map1 = new HashMap<String, Object>();
        map1.put("one", cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
        map1.put("two", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DESCRIPTION)));
        map1.put("three", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_PRICE)));
        listoff.add(map1);
    } while (cursor.moveToNext());
}

if（cursor.moveToFirst（））{
做{
HashMap map1=新的HashMap（）；
map1.put（“一”，cursor.getLong（cursor.getColumnIndex（DBHelper.COLUMN_ID））；
put（“两个”，cursor.getString（cursor.getColumnIndex（DBHelper.COLUMN_DESCRIPTION））；
map1.put（“三”，cursor.getString（cursor.getColumnIndex（DBHelper.COLUMN_PRICE））；
添加（map1）；
}while（cursor.moveToNext（））；
}
已定义
游标.moveToNext（）在你喜欢的时候做
使用前，请始终检查
getCount

if(cursor!=null && cursor.getCount()>0){
cursor.moveToNext();
do {
   HashMap<String, Object> map1 = new HashMap<String, Object>();
    map1.put("one", cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
    map1.put("two", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DESCRIPTION)));
    map1.put("three", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_PRICE)));
    listoff.add(map1);
} while (cursor.moveToNext());
}

if（cursor！=null&&cursor.getCount（）>0）{
cursor.moveToNext（）；
做{
HashMap map1=新的HashMap（）；
map1.put（“一”，cursor.getLong（cursor.getColumnIndex（DBHelper.COLUMN_ID））；
put（“两个”，cursor.getString（cursor.getColumnIndex（DBHelper.COLUMN_DESCRIPTION））；
map1.put（“三”，cursor.getString（cursor.getColumnIndex（DBHelper.COLUMN_PRICE））；
添加（map1）；
}while（cursor.moveToNext（））；
}
@WL是否解决了您的问题？
if (cursor.moveToFirst()) {
    do {
       HashMap<String, Object> map1 = new HashMap<String, Object>();
        map1.put("one", cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
        map1.put("two", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DESCRIPTION)));
        map1.put("three", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_PRICE)));
        listoff.add(map1);
    } while (cursor.moveToNext());
}

if(cursor!=null && cursor.getCount()>0){
cursor.moveToNext();
do {
   HashMap<String, Object> map1 = new HashMap<String, Object>();
    map1.put("one", cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
    map1.put("two", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DESCRIPTION)));
    map1.put("three", cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_PRICE)));
    listoff.add(map1);
} while (cursor.moveToNext());
