Android-快速从列表视图加载数据库

Question

我有一个包含大约300000个单词的sqlite数据库字典。任何人都可以帮我解决从列表视图加载数据库的问题吗？

Answer 1

我建议使用CursorAdapter。创建一个扩展CursorAdapter的类，如下所示：

public class MyCursorAdapter extends CursorAdapter {

    private LayoutInflater inflater;

    public MyCursorAdapter(Context context, Cursor cursor, int flags) {
        super(context, cursor, flags);
        inflater = LayoutInflater.from(context);
    }


    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        // Change the id attribute to match your list item text view
        TextView title = (TextView) view.findViewById(android.R.id.text1);  
        title.setText(cursor.getString(cursor.getColumnIndex(yourColumnName)));
    }


    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        // Change the layout to your custom list item
        return inflater.inflate(android.R.layout.simple_list_item_1, parent, false);
    }

}

然后，要设置列表，您可以写：

Cursor cursor = db.rawQuery(yourQuery);
MyCursorAdapter adapter = new MyCursorAdapter(this, cursor, 0);
setListAdapter(adapter);
