标签： android listview simpleadapter

我正在尝试使用SimpleAdapter生成ListView。我收到以下错误。请帮我修复错误。我的代码和错误日志一样如下。

SimpleAdapter的代码

 SimpleAdapter k=new SimpleAdapter(getActivity(),val,R.layout.contact,new String[]{"name,path"},new int[]{R.id.example_itemname,R.id.path})
    {
      @Override
        public View getView (int position, View convertView, ViewGroup parent)
            { 

final View v = super.getView(position, convertView, parent);
//some codes more here

                return v;
            }
    };
 swipy.setAdapter(k);

val获取其值的数据库代码

 public ArrayList<HashMap<String, String>> swipelistdata() {
ArrayList<HashMap<String, String>> wordList;
wordList = new ArrayList<HashMap<String, String>>();

String selectQuery = "SELECT * FROM contacts";

SQLiteDatabase database = this.getWritableDatabase();
Cursor cursor = database.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
    do {
        HashMap<String, String> map = new HashMap<String, String>();

        map.put("name", cursor.getString(1));
        map.put("path", cursor.getString(3));

        wordList.add(map);
    } while (cursor.moveToNext());
}cursor.close();
database.close();

return wordList;
 }

2 个答案:

答案 0 :(得分：2)

我认为你错了就在这里

new String[]{"name,path"},new int[]{R.id.example_itemname,R.id.path}

数组必须具有相同的长度。试试这个：

new String[]{"name","path"},new int[]{R.id.example_itemname,R.id.path})

答案 1 :(得分：0)

像这样更改您的代码。

boolean isPresent = true;
Cursor cursor = database.rawQuery(selectQuery, null);
if (cursor.moveToFirst()) {
    do {
        HashMap<String, String> map = new HashMap<String, String>();

        map.put("name", cursor.getString(1));
        map.put("path", cursor.getString(3));

        wordList.add(map);
        isPresent = cursor.moveToNext()
    } while (isPresent);

希望这会奏效。让我知道它是否有效。
