我在我的应用程序中使用tabHost的要求是，当选择任何选项卡标签指示灯的颜色应该改变，我提到这个例子How设置选项卡查看指示灯背景色的Andr​​oid 但我没有理解 这是我的code：

I am using tabHost in my application and the requirement is that when any tab is selected the color of tab indicator should change ,I referred this example How to set Tab View Indicator background color in Android but i didn't understood Here is my code:

    TabHost tabHost = getTabHost();  // The activity TabHost

            TabHost.TabSpec spec;  // Reusable TabSpec for each tab
            Intent intent;  // Reusable Intent for each tab

            // Create an Intent to launch an Activity for the tab (to be reused)
            intent = new Intent().setClass(this, HomePage.class);
            // Initialize a TabSpec for each tab and add it to the TabHost
            spec = tabHost.newTabSpec("tabOne");  
            spec.setContent(intent);  
            spec.setIndicator("Home");  
            tabHost.addTab(spec);
            // Squash the tab a little bit horizontally
            tabHost.getTabWidget().getChildAt(0).getLayoutParams().height = 40;
            tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;

            // Bump the text size upll.getChildAt(0);

            // Do the same for the other tabs
            intent = new Intent().setClass(this, MoteIt.class);
            spec = tabHost.newTabSpec("tabTwo");  
            spec.setContent(intent);  
            spec.setIndicator("moteit");

            tabHost.addTab(spec);
            tabHost.getTabWidget().getChildAt(1).getLayoutParams().height = 40;


            intent = new Intent().setClass(this, Lifeline.class);
            spec = tabHost.newTabSpec("tabThree");  
            spec.setContent(intent);  
            spec.setIndicator("lifeline");
            tabHost.addTab(spec);
            tabHost.getTabWidget().getChildAt(2).getLayoutParams().height = 40;


            intent = new Intent().setClass(this, CircleOfTrust.class);
            spec = tabHost.newTabSpec("tabfour");  
            spec.setContent(intent);  
            spec.setIndicator("Cot");
            tabHost.addTab(spec);
            tabHost.getTabWidget().getChildAt(3).getLayoutParams().height = 40;

            intent = new Intent().setClass(this, Search.class);
            spec = tabHost.newTabSpec("tabFive");  
            spec.setContent(intent);  
            spec.setIndicator("Search");
            tabHost.addTab(spec);
            tabHost.getTabWidget().getChildAt(4).getLayoutParams().height = 40;
            tabHost.getTabWidget().setStripEnabled(true);
            tabHost.setCurrentTab(0);

在此先感谢

该解决方案对我的作品，也是其工作的2.1+的Andr​​oid，它的创建自定义选项卡布局

This solution works for me and also its working for 2.1+ android, its create custom tab layout

code：

private TabHost mTabHost;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    setupTabHost();
    mTabHost.getTabWidget().setDividerDrawable(R.drawable.fake_divider);

    setupTab(new TextView(this), "123", R.id.tab1);
    setupTab(new TextView(this), "abc", R.id.tab2);
    setupTab(new TextView(this), "fav", R.id.tab3);

    mTabHost.setCurrentTab(0);
}

private void setupTabHost() {
    mTabHost = (TabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup();
}

private void setupTab(final View view, final String tag, final int res) {
    View tabview = createTabView(mTabHost.getContext(), tag);
    TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(res);
    mTabHost.addTab(setContent);
}

private static View createTabView(final Context context, final String text) {
    View view = LayoutInflater.from(context).inflate(R.layout.tabwidget_bg, null);
    TextView tv = (TextView) view.findViewById(R.id.tabsText);
    tv.setText(text);
    return view;
}

main.xml中：

in main.xml:

<TabHost
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

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

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

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:measureAllChildren="true" >

            <LinearLayout
                android:id="@+id/tab1"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:baselineAligned="true"
                android:orientation="vertical" >
        ... etc

自定义布局tabwidget_bg.xml：

custom layout tabwidget_bg.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tabsLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/tab_bg_selector"
    android:gravity="center"
    android:padding="10dp"
    android:layout_margin="0dp" >

    <TextView
        android:id="@+id/tabsText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@android:color/white"
        android:textSize="15sp" />

</LinearLayout>

现在，你可以自定义您的自定义选项卡layot​​为u可以了，你的活动标签ňtab_bg_selector.xml颜色

Now you can customize your custom tab layot as u can, and color of your active tab n tab_bg_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Active tab -->
    <item android:drawable="@drawable/tab_bg_selected" android:state_focused="false" android:state_pressed="false" android:state_selected="true"/>
    <!-- Inactive tab -->
    <item android:drawable="@drawable/tab_bg_unselected" android:state_focused="false" android:state_pressed="false" android:state_selected="false"/>
    <!-- Pressed tab -->
    <item android:drawable="@drawable/tab_bg_active" android:state_pressed="true"/>
    <!-- Selected tab (using d-pad) -->
    <item android:drawable="@drawable/tab_bg_selected" android:state_focused="true" android:state_pressed="false" android:state_selected="true"/>

</selector>
