过去一周，我一直在努力将工作活动添加到使用片段的滑动选项卡视图中。我真的不知道从哪里开始，滑动标签视图可以自行运行，活动也可以自行运行，任何人都可以帮忙解决这个问题吗？
TabPagerAdapter.java

public TabPagerAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
@Override
public Fragment getItem(int i) {
switch (i) {
case 0:
//Fragement for Android Tab
return new MainActivity1();
case 1:
//Fragment for Ios Tab
return new Maps();
// case 2:
//Fragment for Windows Tab
// return new Maps();
return null;
}
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return 2; //No of Tabs
}
}

答案 0 :(得分：1)
您无法将活动放入ViewPager。但是，您可以将MainActivity1转换为片段。
