如何使用arrayadapter？

Question

我正在开发一个应用程序，它可以搜索表“employee”并返回结果。如何使用阵列适配器执行此操作？我是android的新手。

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;
    }


}

Answer 1

您应该使用ListActivity或ListFragment，并使用CursorAdapter填充它们。(SimpleCursorAdapter)是一个实现类

可以从doMySearchMethod返回的列表中填充CursorAdapter。

Answer 2

您不必使用数组适配器，而是使用SimpleCursorAdapter。如果你需要一个使用它的例子，你可以看看Notepad tutorial。
