如何在TabWidget的每個選項卡中添加更多項目？

Question

我已經用TabHost和TabWidget編寫了一個簡單的標籤程序，但是我只能添加一個項目到每個標籤..我想添加一個textview，一個imageview和一個按鈕，但我無法..這是我的xml代碼：

<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/tabhost" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

<LinearLayout 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 

    <TabWidget android:id="@android:id/tabs" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content"/> 

    <FrameLayout 
     android:id="@android:id/tabcontent" 
     android:layout_width="fill_parent" 
     android:layout_height="98dp" > 

     <TextView 
      android:id="@+id/tab1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginLeft="10dp" 
      android:text="Tab1" 
      android:textColor="#ffffff" 
      android:textSize="16sp" 
      android:textStyle="bold" /> 

     <TextView 
      android:id="@+id/tab2" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginLeft="10dp" 
      android:text="Tab2" 
      android:textColor="#ffffff" 
      android:textSize="16sp" 
      android:textStyle="bold" /> 

     <TextView 
      android:id="@+id/tab3" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_marginLeft="10dp" 
      android:text="Tab3" 
      android:textColor="#ffffff" 
      android:textSize="16sp" 
      android:textStyle="bold" /> 

    </FrameLayout> 

</LinearLayout> 
</TabHost> 

如何將圖像視圖與現有文本視圖一起添加到Tab1？

您可以在操作欄中使用標籤，就像這樣：

private ViewPager mPager; 
private PagerAdapter mPagerAdapter; 
private static final int NUM_PAGES = 3; 

中的onCreate（）

final ActionBar actionBar = getActionBar(); 
    actionBar.setDisplayHomeAsUpEnabled(true); 

    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

    mPager = (ViewPager) findViewById(R.id.pager); 
    mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager()); 
    mPager.setAdapter(mPagerAdapter); 
    mPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { 
     @Override 
     public void onPageSelected(int position) { 
      actionBar.setSelectedNavigationItem(position); 
     } 
    }); 

    ActionBar.TabListener tabListener = new ActionBar.TabListener() { 

     @Override 
     public void onTabReselected(Tab tab, 
       android.app.FragmentTransaction ft) { 

     } 

     @Override 
     public void onTabSelected(Tab tab, 
       android.app.FragmentTransaction ft) { 
      mPager.setCurrentItem(tab.getPosition()); 
     } 

     @Override 
     public void onTabUnselected(Tab tab, 
       android.app.FragmentTransaction ft) { 
     } 

    }; 

    for (int i = 0; i < mPagerAdapter.getCount(); i++) { 
     actionBar.addTab(actionBar 
       .newTab() 
       .setText(mPagerAdapter.getPageTitle(i)) 
       .setIcon(
         ((ScreenSlidePagerAdapter) mPagerAdapter) 
           .getPageIcon(i)) 
       .setTabListener(tabListener)); 
    } 

private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { 
    public ScreenSlidePagerAdapter(FragmentManager fm) { 
     super(fm); 
    } 

    @Override 
    public Fragment getItem(int position) { 
     switch (position) { 
     case 0: 
      return Fragment.instantiate(MainActivity.this, 
        Fragment_sports.class.getName()); 
     case 1: 
      return Fragment.instantiate(MainActivity.this, 
        Fragment_casino.class.getName()); 
     case 2: 
      return Fragment.instantiate(MainActivity.this, 
        Fragment_live_betting.class.getName()); 
     default: 
      break; 
     } 
     return null; 
    } 

    @Override 
    public int getCount() { 
     return NUM_PAGES; 
    } 

    @Override 
    public CharSequence getPageTitle(int position) { 
     String tabLabel = null; 
     switch (position) { 
     case 0: 
      tabLabel = " Sports"; 
      break; 
     case 1: 
      tabLabel = "Casino"; 
      break; 
     case 2: 
      tabLabel = "Live Betting"; 
      break; 
     } 

     return tabLabel; 
    } 

    public int getPageIcon(int position) { 
     int id = 0; 
     switch (position) { 
     case 0: 
      id = R.drawable.icon_all_sports_d; 
      break; 
     case 1: 
      id = R.drawable.icon_favourites_d; 
      break; 
     case 2: 
      id = R.drawable.icon_live_d; 
      break; 
     default: 
      break; 
     } 
     return id; 

    } 
} 

和你main_activity.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

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

</RelativeLayout>
