如何將TabHost保持在底部？

Question

我是Android新手，剛剛創建了我的第一個TabHost。下面是XML的代碼：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:weightSum="1"> 

     <TextView 
      style="@style/NormalFont" 
      android:text="@string/stats" 
      android:layout_weight="0.10"/> 


     <TabHost 
      android:id="@+id/TabHostStats" 
      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="fill_parent"> 
         <ScrollView 
          android:id="@+id/ScrollViewSmileyFilter" 
          android:scrollbars="vertical" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"> 
          <TableLayout 
           android:id="@+id/TableLayoutSmileyFilter" 
           android:layout_width="fill_parent" 
           android:layout_height="fill_parent" 
           android:stretchColumns="*"> 
          </TableLayout> 
         </ScrollView> 
         <ScrollView 
          android:id="@+id/ScrollViewADFilter" 
          android:scrollbars="vertical" 
          android:layout_width="fill_parent" 
          android:layout_height="fill_parent"> 
          <TableLayout 
           android:id="@+id/TableLayoutADFilter" 
           android:layout_width="fill_parent" 
           android:layout_height="fill_parent" 
           android:stretchColumns="*"> 
          </TableLayout> 
         </ScrollView> 
        </FrameLayout> 
      </LinearLayout> 
     </TabHost> 
</LinearLayout> 

和這裏的活動代碼：

public class StatsActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.stats); 

     TabHost host = (TabHost) findViewById(R.id.TabHostStats); 
     host.setup(); 


     /** Dieser Code generiert den Tag für die Smileyfilter Stats**/ 

     TabSpec SmileyFilterTab = host.newTabSpec("sftab"); 
     SmileyFilterTab.setIndicator(getResources().getString(R.string.sfstats)); 
     SmileyFilterTab.setContent(R.id.ScrollViewSmileyFilter); 
     host.addTab(SmileyFilterTab); 

     /**Dieser Code generiert den Tag für die Auto Delete Filter Stats **/ 

     TabSpec AutoDeleteTab = host.newTabSpec("adtab"); 
     AutoDeleteTab.setIndicator(getResources().getString(R.string.adstats)); 
     AutoDeleteTab.setContent(R.id.ScrollViewADFilter); 
     host.addTab(AutoDeleteTab); 



    } 
} 

所以我TabHosts的寄存器之上。但我希望他們在按鈕上，我該怎麼做？還有如何以及在哪裏可以改變它們的顏色。我希望他們用黑色點擊，如果他們點擊藍色。

Answer 1

我見過很多實現。但這個傢伙我最喜歡。

他有tutorial和下載sample project。

編輯 畢竟這些年來，鏈接似乎被打破。所以這裏是代碼。 這裏是一個alternate link，以防萬一這裏是代碼。

Answer 2

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@android:id/tabhost" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 
    <RelativeLayout 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:padding="3dp"> 
     <FrameLayout 
      android:id="@android:id/tabcontent" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:layout_weight="1" /> 
     <TabWidget 
      android:id="@android:id/tabs" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_alignBottom = "@android:id/tabcontent" 
      /> 
    </RelativeLayout> 
</TabHost> 

在屏幕底部創建標籤佈局使用TabWidget以下main.xml中：

android:layout_alignBottom = "@android:id/tabcontent"
