Question

我想在我的应用程序上使用垂直幻灯片，所以我实现了这个库： https://github.com/castorflex/VerticalViewPager 通过添加implementation com.github.castorflex.verticalviewpager:library:19.0.1 在build.gradle的依赖项中。

现在，我想将此viewPager添加到我的xml文件中（如果它是本机水平View分页器，我将在布局中进行类似<android.support.v4.ViewPager>的操作）但是我尝试的所有操作都失败了，它的语法是什么？（以前从未与图书馆合作过）我也尝试过<github.castorflex.verticalviewpager> 谢谢

您必须输入xml

        scrollPane.setBounds(36, 37, 407, 79);
        getContentPane().add(scrollPane);

        leaderboard_table.setFont(new Font("Consolas", Font.PLAIN, 12));
        GroupLayout groupLayout = new GroupLayout(frmLeaderboards.getContentPane());
        groupLayout.setHorizontalGroup(
            groupLayout.createParallelGroup(Alignment.LEADING)
                .addComponent(leaderboard_table, GroupLayout.DEFAULT_SIZE, 434, Short.MAX_VALUE)
        );
        groupLayout.setVerticalGroup(
            groupLayout.createParallelGroup(Alignment.LEADING)
                .addComponent(leaderboard_table, GroupLayout.DEFAULT_SIZE, 461, Short.MAX_VALUE)

        frmLeaderboards.getContentPane().setLayout(groupLayout);
    }
}
