android - void是变量onListItemClick的无效类型吗？

我一直在尝试在扩展onClickListener的android活动上设置简单的ListActivity。

在create方法的此类中，我创建了一个微调器对象，当用户选择一个项目时，将根据用户选择的内容（从光标请求中填充）创建一个arrayAdapter列表项。这是在同一类的另一个方法中生成的。

ArrayAdapter<String> playerAdapter = new ArrayAdapter<String>(this,
            R.layout.match_update_rows, R.id.player_name, playerItems);

    setListAdapter(playerAdapter);

我正在尝试在此新列表上添加点击监听器。我已经添加了：

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Intent i = new Intent(this, PlayerFixtureScore.class);
        i.putExtra("RowId", id);
        startActivity(i);
    }

但是，我在protected void onListItemClick行上遇到错误。

Multiple markers at this line
- Syntax error on token ")", ; expected
- Syntax error on token ",", ; expected
- Duplicate local variable position
- Syntax error on token ",", ; expected
- Duplicate local variable id
- Duplicate local variable l
- Syntax error on token "(", ; expected
- Duplicate local variable v
- Syntax error on token ",", ; expected
- void is an invalid type for the variable
 onListItemClick

另外，如果我选择onListItemClick行，Eclipse会说'void is an invalid type for the variable onListItemClick'？

如果删除了单击侦听器代码，所有方法都将起作用，只是无法确定如何在arrayAdapter项目上添加侦听器，这样我就可以知道用户单击了哪个项目-感谢您提供任何帮助！

public class MatchUpdate extends ListActivity {
/** Called when the activity is first created. */
private int cursorCounter = 0;
private int spinnerSelected;
/** Set up the db for inital use */
DataBaseHelper myDbHelper = new DataBaseHelper(this);
Match match;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.match_update);

    try {
        myDbHelper.createDataBase();
    } catch (IOException ioe) {
        throw new Error("Unable to create database");
    }
    try {
        myDbHelper.openDataBase();
    } catch (SQLException sqle) {
        throw sqle;
    }

    // create a spinner for fixture selection
    Spinner fixtureSpin = (Spinner) findViewById(R.id.fixtures);

    // Get all fixtures for Spinner...
    Cursor cur = myDbHelper.getFixtures();

    // create match object for cursor results
    match = new Match(cur.getCount());

    // Populate match object with Cursor results
    for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) {

        cursorCounter++;
    }

    // Set up adapters for fixture spinner
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_spinner_item, match.getFixtureList());

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // Set up fixture spinner
    fixtureSpin.setAdapter(adapter);

    // Set fixture spinner listener
    fixtureSpin.setOnItemSelectedListener(new MyOnItemSelectedListener());

}

public class MyOnItemSelectedListener implements OnItemSelectedListener {

    public void onItemSelected(AdapterView<?> parent, View view, int pos,
            long id) {
        spinnerSelected = parent.getSelectedItemPosition();
        updatePlayers(match);
    }

    public void onNothingSelected(AdapterView<?> parent) {
        // Do nothing.
    }
}

public void updatePlayers(Match thisMatch) {

    // Get players for selected fixture based on Spinner selection
    Cursor playerCur = myDbHelper.getFixturePlayers(
            thisMatch.getHomeId(spinnerSelected),
            thisMatch.getAwayId(spinnerSelected));

    // set up simple ArrayAdapter to hold player names
    String[] playerItems;
    playerItems = new String[playerCur.getCount()];
    int cnt = 0;

    // pull player data from cursor, into a simple array
    for (playerCur.moveToFirst(); !playerCur.isAfterLast(); playerCur
            .moveToNext()) {
        playerItems[cnt] = playerCur.getString(0);
        cnt++;

    }

    ArrayAdapter<String> playerAdapter = new ArrayAdapter<String>(this,
            R.layout.match_update_rows, R.id.player_name, playerItems);

    setListAdapter(playerAdapter);

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Intent i = new Intent(this, PlayerFixtureScore.class);
        i.putExtra("RowId", id);
        startActivity(i);
    }
}

}

最佳答案

方法声明需要在类定义的上下文中进行。当尝试在另一个方法中声明一个方法时，会报告与此类似的错误。
