我目前正在制作一本类似游戏的小书以用于教育目的，并且我正在使用页面查看器将我的 Strings.xml 中的信息放在每个页面上。这是一本相当小的书，所以我就是这样做的。我已显示所有页面，您可以毫无问题地滑动浏览。当我只想显示一定间隔的页面时，我的问题就开始了。游戏共有三节课。第一课有 2 页（1-2），第二课有（3-9），第三课有（10-15）。总共有15页的信息。
有没有办法让页面查看器只显示一定间隔的页面？
我让用户选择一个按钮，这会将选择的课程的意图发送到另一个名为 BookActivity 的类。从那里我想弄清楚点击了哪一课，并希望根据它显示某些页面。这是 bookActivity 类。
public class BookActivity extends Activity
{
private String getLessonName;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = getIntent();
// getting object's properties from LoginActivity class.
getLessonName = intent.getStringExtra("nameOfLesson");
MyPageAdapter adapter = new MyPageAdapter();
ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
// Button addBasicQuestionsForFirstLesson = (Button)findViewById(R.id.addBasicQuestionsButton);
myPager.setAdapter(adapter);
if(getLessonName.equals("one"))
{
myPager.setCurrentItem(0);
if(myPager.getCurrentItem() == 1)
{
myPager.setCurrentItem(1);
}
}
else if(getLessonName.equals("two"))
{
myPager.setCurrentItem(2);
if(myPager.getCurrentItem() == 8)
{
myPager.setCurrentItem(8);
}
}
else if(getLessonName.equals("three"))
{
myPager.setCurrentItem(9);
if(myPager.getCurrentItem()==14)
{
myPager.setCurrentItem(14);
}
}
}
}
非常感谢你帮我看这个。如果有人知道如何做这样的事情，我将不胜感激。如果有办法更好地做到这一点，我不想为单独的页面制作多个活动......
