Java Android选项卡，列表和按钮在单击后不会滑动

第一个问题：我的标签在按下按钮后不会滑动，我必须手动点击标签。在按下按钮之前，它可以完美地滑动

第二个问题：我的列表也没有显示在我的标签上。假设每次我按下带有输入的按钮时，adpater都会向listview吐出一个值，但列表就是不显示

public class tablogger extends FragmentActivity { 

ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;

ArrayAdapter<String> adapter;
ArrayList<String> list = new ArrayList<String>();
EditText benchStat;
EditText benchreps;
String benchfinals;
ListView lv;




@Override 
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tablogger);
    TabAdapter = new TabPagerAdapter(getSupportFragmentManager());



    Tab = (ViewPager)findViewById(R.id.pager);
    Tab.setOnPageChangeListener(
            new ViewPager.SimpleOnPageChangeListener() { 
                @Override 
                public void onPageSelected(int position) {
                    actionBar = getActionBar();
                    actionBar.setSelectedNavigationItem(position);                    }
            }); 
    Tab.setAdapter(TabAdapter);
    actionBar = getActionBar();
    //Enable Tabs on Action Bar 
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    ActionBar.TabListener tabListener = new ActionBar.TabListener(){
        @Override 
        public void onTabReselected(android.app.ActionBar.Tab tab,
                                    FragmentTransaction ft) {
            // TODO Auto-generated method stub 
        } 
        @Override 
        public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
            Tab.setCurrentItem(tab.getPosition());
        } 
        @Override 
        public void onTabUnselected(android.app.ActionBar.Tab tab,
                                    FragmentTransaction ft) {
            // TODO Auto-generated method stub 
        }}; 
    //Add New Tab 
    actionBar.addTab(actionBar.newTab().setText("Bench").setTabListener(tabListener));
    actionBar.addTab(actionBar.newTab().setText("Squat").setTabListener(tabListener));
    actionBar.addTab(actionBar.newTab().setText("Dead").setTabListener(tabListener));

    setResult(RESULT_OK, data);
    super.finish(); 
} 

}

您必须使用：

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

---

为每个选项卡提供片段，并使用片段布局提供按钮等。

首先，在fragents中不调用setContentView。我认为listview没有显示任何内容，因为列表是空的。我的选项卡在按下按钮之前滑动良好。这就是问题所在。我试过你说的话，但一点也没有影响。你还有什么建议吗？

<android.support.v4.view.ViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
