自定义操作栏tabview

Question

我正在尝试在操作栏中创建自定义tabview，如下所示：

我有这个观点：

我想更改tabviews指标的背景，因此背景颜色变得不可见，我们在选定的tabview指标下面有绿线。

这是我的代码（我使用默认tabview）：

public class BaseActivity extends Activity{

    ActionBar bar;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState); setContentView(R.layout.base_activity);

        bar = getActionBar(); 

        // Change action bar background

        BitmapDrawable background = new BitmapDrawable(BitmapFactory.decodeResource(getResources(), R.drawable.background_actionbar)); background.setTileModeX(android.graphics.Shader.TileMode.REPEAT); 

        bar.setBackgroundDrawable(background);

        bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

        ActionBar.Tab tabA = bar.newTab().setText(getResources().getString(R.string.documents)); 

        ActionBar.Tab tabB = bar.newTab().setText(getResources().getString(R.string.videos)); 

        ActionBar.Tab tabC = bar.newTab().setText(getResources().getString(R.string.menu_settings)); 

        Fragment fragmentA = new DocumentsListFragment();

        Fragment fragmentB = new VideosListFragment();

        Fragment fragmentC = new UserAccountFragment();

        tabA.setTabListener(new MyTabsListener(fragmentA)); 

        tabB.setTabListener(new MyTabsListener(fragmentB)); 

        tabC.setTabListener(new MyTabsListener(fragmentC)); 

        bar.addTab(tabA);

        bar.addTab(tabB);

        bar.addTab(tabC);
    }


    protected class MyTabsListener implements ActionBar.TabListener
    {
        private Fragment fragment;

        public MyTabsListener(Fragment fragment) {
            this.fragment = fragment; }

        @Override

        public void onTabSelected(Tab tab, FragmentTransaction ft)
        {
            ft.replace(R.id.fragment_place, fragment, null); }

        @Override

        public void onTabReselected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub

        }

        @Override

        public void onTabUnselected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub

        }
    }

}

请问，我怎么能夸大那些tabview指标。

Answer 1

将这些内容添加到styles.xml中的值

下

 <style name="Theme.AndroidDevelopers" parent="Theme.Sherlock.Light.ForceOverflow"> 
 <item name=" android:actionBarItemBackground">@drawable/ad_selectable_background
 </item>
    <item name="android:actionBarTabStyle">@style/MyActionBarTabStyle</item>
    <item name="actionBarTabStyle">@style/MyActionBarTabStyle</item>
 </style>




<style name="MyActionBarTabStyle" parent="Widget.Sherlock.Light.ActionBar.TabBar">
    <item name="android:background">@drawable/actionbar_tab_bg</item>
   <item name="android:gravity">center</item>
   <item name="android:layout_gravity">center</item>
    <item name="android:paddingLeft">10dp</item>
    <item name="android:paddingRight">10dp</item>
</style>

这类似于Tab选择器：

 <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/ad_tab_selected_pressed_holo"           android:state_selected="true"/>
<item android:drawable="@android:color/transparent"/>
