android - 如何使用数组适配器？

Question

我正在制作一个可以搜索表“员工”并返回结果的应用程序。我如何使用阵列适配器来执行此操作？我是 Android 新手。

public class SimpleSearch extends Activity {
    /** Called when the activity is first created. */
    protected SQLiteDatabase db;
    Intent intent = getIntent();
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Get the intent, verify the action and get the query
        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);
          doMySearch(query);
        }
    }
    public List<String> doMySearch(String query) {
        List<String> result = new ArrayList<String>();

        Cursor c = db.query(
                "employee", 
                new String[] { "_id" }, // The column you want as a result of the Query
                "firstName like '%?%' OR lastName like '%?%' OR officePhone like '%?%'", // The where-Clause of the statement with placeholders (?)
                new String[] { query, query, query }, // One String for every Placeholder-? in the where-Clause
                );
        while (c.moveToNext()) {
            result.add(c.getString(0));
        }
        c.close();
        return result;
    }


}

你不必使用数组适配器，使用SimpleCursorAdapter反而。如果您需要使用它的示例，可以查看 Notepad tutorial .
