標籤之間的間距不一致

Question

有誰知道這會導致什麼？

我創建了一個自定義選項卡的佈局和我要麼需要的間距或沒有，只是一致性。理想情況下，我不想使用間距，但我已經閱讀過，這可能不適用於Android的操作欄。

這是我使用的XML代碼：

public class Tabs extends TabActivity { 

private static final Properties properties = Properties.getInstance(); 
TabHost mTabHost; 

public void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.tabs); 

    mTabHost = getTabHost(); 

    addTab(getString(R.string.text_tabs_1), R.drawable.listing_tab_active, new Intent(this, Main.class), R.drawable.listing_tab_inactive); 
    addTab(getString(R.string.text_tabs_2), R.drawable.keyword_tab_active, new Intent(this, Keywords.class), R.drawable.keywords_tab_inactive); 
    addTab(getString(R.string.text_tabs_3), R.drawable.saved_tab_active, new Intent(this, Saved.class), R.drawable.saved_tab_inactive); 
} 

private void addTab(String label, int drawableId, Intent intent, int imageId) 
{ 
    TabHost.TabSpec spec = mTabHost.newTabSpec(label); 

    View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tabs_bg, getTabWidget(), false); 

    ((TextView)tabIndicator.findViewById(R.id.tabText)).setText(label); 

    ((ImageView)tabIndicator.findViewById(R.id.tabImage)).setImageResource(imageId); 

    spec.setIndicator(tabIndicator); 
    spec.setContent(intent); 

    mTabHost.addTab(spec);  
} 
} 

tabs.xml

<LinearLayout 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:padding="0dp">

砍了自己的選項卡像這樣的東西：

<?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"> 

    <LinearLayout 
      android:orientation="vertical" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" 
      android:background="#FFFFFF"> <!-- android:padding="5dp" --> 

     <FrameLayout 
       android:id="@android:id/tabcontent" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 


       android:layout_weight="1"/> 

     <!--<FrameLayout--> 
       <!--android:id="@+id/realtabcontent"--> 
       <!--android:layout_width="fill_parent"--> 
       <!--android:layout_height="wrap_content"--> 
       <!--android:layout_weight="1"/>--> 

     <LinearLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:orientation="horizontal"> 
      <Button android:id="@+id/tab1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:background="@drawable/tab1_selector" /> 
      <Button android:id="@+id/tab2" 
        android:layout_height="wrap_content" android:layout_width="wrap_content" android:background="@drawable/tab2_selector" /> 
      <Button android:id="@+id/tab3"  android:layout_height="wrap_content" android:layout_width="wrap_content" android:background="@drawable/tab3_selector" /> 
      <Button android:id="@+id/tab4" android:layout_height="wrap_content" android:layout_width="wrap_content" android:background="@drawable/tab4_selector" /> 
      <Button android:id="@+id/tab5" android:layout_height="wrap_content" android:layout_width="wrap_content" android:background="@drawable/tab5_selector" /> 

     </LinearLayout> 


     <TabWidget 
       android:id="@android:id/tabs" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:layout_weight="0" 
       android:visibility="gone"/> 

    </LinearLayout> 

</TabHost> 

Answer 2

我想通了。向TabWidget添加android：background =「@ drawable/tab_bg_selector」固定間距：

<TabWidget 
     android:id="@android:id/tabs" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:padding="0dp" 
     android:background="@drawable/tab_bg_selector" 
    />
