好吧所以我使用Swipe + Tab View创建了一个应用程序我想让每个标签显示一个不同的.xml页面，如果你点击上面你可以下载我的工作区进行编辑..我真的需要帮助，如果你想要的话请特别注意我可以设置teamviwer如果它可以更快..如果你不想下载文件因为你认为“它有病毒”只是在下面做出回复这里是我的mainactivity.java的代码

以下是我的适配器解决您的问题的示例。 TabsPagerAdapter只是一个单独的类。
/**
* This is a helper class that implements the management of tabs and all
* details of connecting a ViewPager with associated TabHost. It relies on a
* trick. Normally a tab host has a simple API for supplying a View or
* Intent that each tab will show. This is not sufficient for switching
* between pages. So instead we make the content part of the tab host
* 0dp high (it is not shown) and the TabsAdapter supplies its own dummy
* view to show as the tab content. It listens to changes in tabs, and takes
* care of switch to the correct paged in the ViewPager whenever the selected
* tab changes.

这是一个微小修改的android示例framentadapter。
示例用法 MainActivity.java

public void onCreate(Bundle savedInstanceState){
setContentView(R.layout.activity_main);
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
mViewPager = (ViewPager) findViewById(R.id.pager);
mTabsAdapter = new TabsPagerAdapter(this, mTabHost, mViewPager,null, getSupportFragmentManager());
mTabsAdapter.addTab("Button", "button",getResources().getDrawable(R.drawable.yourdrawable),
ButtonFragment.class, R.layout.yourtablayout);
mTabsAdapter.addTab("Text","text",getResources().getDrawable(R.drawable.yourdrawable), TextFragment.class, R.layout.yourtablayout);
//This is needed so your tabs do not reload each time
mViewPager.setOffscreenPageLimit(mTabsAdapter.getCount());
}

如果你想从另一个片段中获取id的值，你可以使用下面的，基于FragmentPage1声明了以下公共变量
public static String a,b,c;
在FragmentPage1.java中
public class FragmentPage3 extends Fragment {
Context c;
String a = "";
String b = "";
String c = "";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.Fragment_3, null);
a = FragmentPage1.a;
b = FragmentPage1.b;
c = FragmentPage1.c;
