手动触发Pull以刷新Container

Question

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

Answer 1

这很容易，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”侦听器，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();
