如何將數據提取到文本視圖中？

Question

這是我將數據庫值提取到listview代碼。

private void fetchData2() {
    db = helper.getReadableDatabase();
    Cursor c = db.query(DBhelper.TABLE2, null, null, null, null, null, null);
    adapter = new SimpleCursorAdapter(
                this,
                R.layout.row2,
                c,
                new String[]{DBhelper.Amount},
                new int[]{R.id.lbl});
    list.setAdapter(adapter);
}

我只想更改此代碼以將值放入textview 中，

你可以這樣做...

if(c.moveToFirst()){

String data = c.getString(c.getColumnIndex("Column's Index"));

yourTextView.setText(data);

}
