如何爲TabWidget選項卡添加父對齊？

Question

我正在編寫java代碼來創建一個tabs.i已經完成了。但是現在我希望tab小部件位於screen.i的下部，希望通過添加此代碼可以實現這一點。 android:layout_alignParentBottom="true"讓我知道如何添加這個編碼。我想要類似這樣的樣子http://android-pro.blogspot.com/2010/08/iphone-like-tab-bar-in-android.html

TabHost tabHost = new TabHost（this）;

tabHost.setLayoutParams(
      new LinearLayout.LayoutParams(
        LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 
    RelativeLayout rl=new RelativeLayout(ContactManager.this); 

    RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT); 

    rlp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, android.R.id.tabs); 
    rl.setLayoutParams(rlp); 
    tabHost.addView(rl); 

    TabWidget tabWidget = new TabWidget(this); 
    tabWidget.setId(android.R.id.tabs); 
    rl.addView(tabWidget, new LinearLayout.LayoutParams(
       LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 

    FrameLayout frameLayout = new FrameLayout(this); 
    frameLayout.setId(android.R.id.tabcontent); 
    frameLayout.setPadding(0, 55, 0, 0); 


    rl.addView(frameLayout, new LinearLayout.LayoutParams(
       LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
    tabHost.setup();

用XML進行佈局會容易得多。您將需要自定義選項卡圖像，因爲股票看起來並不在屏幕的底部。
