ListActivity中的AndroidAnnotations和上下文菜单

Question

我有一个从ListActivity继承并使用AndroidAnnotations的活动.虽然.onListItemClick工作正常,但列表项的上下文菜单根本不会显示,甚至.onCreateContextMenu不会被调用,但是.onListItemClick在长时间点击列表项后会触发.这是我的代码:

@OptionsMenu(R.menu.places)
@EActivity(R.layout.places)
public class PlacesPicker extends ListActivity {

    private static String[] DATA_SOURCE = { PlacesDB.PLACE_NAME, PlacesDB.PLACE_DESC };
    private static int[] DATA_DESTINATION = { R.id.place_name, R.id.place_desc };

    public static ListView lv;

    @Bean
    PlacesDB db;

    Cursor cursor;

    @AfterInject
    public void init() {

        cursor = db.getPlaces(null, null);
        startManagingCursor(cursor);

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.place_item, cursor, DATA_SOURCE, DATA_DESTINATION);
        setListAdapter(adapter);

        lv = getListView();

        registerForContextMenu(lv);

    }

    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
                // It works fine
                // It works even after long tap instead of context menu!
        Toast.makeText(this, "Item clicked!", Toast.LENGTH_SHORT).show();
    }

    @OptionsItem
    public void addPlace(){
                // It works OK too
        startActivity(new Intent(this, PlaceEditor_.class));

    }

    public void editPlace() {
        // ...skipped for brevity...
    }

    public void deletePlace() {
            // ...skipped...
    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
                // This isn't ever called!
        super.onCreateContextMenu(menu, v, menuInfo);

        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.place_options, menu);
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        // ...skipped...
    }

}

谁能告诉我这里有什么问题？谢谢你提前.

我知道了!这是我自己的错误:该.init()方法必须注释为@AfterViews,而不是@AfterInject.它的工作原理是这样的:在ListActivity有一个默认的ListView创建的时候,那么我的豆PlacesDB注入,之后将触发的@AfterInject方法,即.init()在默认 的ListView注册为上下文菜单,之后我R.layout.places被设置为活动内容视图与另一 ListView控件这是不是注册!因此,更改注释以@AfterViews使之后.init()运行然后我自己的ListView从布局注册上下文菜单,一切都开始工作:) .setContentView(R.layout.places)
