codenameone - 手动触发 Pull 刷新容器

Question

如果我想在加载表单后手动触发 Codename One 中的 Container 上的 Pull to Refresh。请告知是否有人有任何想法。

Answer 1

很简单，诀窍是使用 showListener .假设这是起始代码(取自 Codename One Developer Guide, section "Pull to refresh" ):

    Form hi = new Form("Pull To Refresh", BoxLayout.y());
    hi.getContentPane().addPullToRefresh(() -> {
        hi.add("Pulled at " + L10NManager.getInstance().formatDateTimeShort(new Date()));
    });
    hi.show();

要在加载表单后调用“Pull to Refresh”监听器，您可以这样做:

    Form hi = new Form("Pull To Refresh", BoxLayout.y());
    Runnable myRunnable = () -> {
        hi.add("Pulled at " + L10NManager.getInstance().formatDateTimeShort(new Date()));
    };
    hi.getContentPane().addPullToRefresh(() -> {
        myRunnable.run();
    });
    hi.addShowListener(l -> {
        myRunnable.run();
    });
    hi.show();
