Answer 2

我已经完成了与显示分数相关的 tabhost 代码

    TabHost host = getTabHost();
    host.setup ();

    TabSpec allScoresTab = host.newTabSpec("allTab");
    allScoresTab.setIndicator(getResources().getString(R.string.all_scores), getResources().getDrawable(android.R.drawable.star_on));
    allScoresTab.setContent(R.id.ScrollViewAllScores);
    host.addTab(allScoresTab);

    TabSpec friendScoresTab = host.newTabSpec("friendsTab");
    friendScoresTab.setIndicator(getResources().getString(R.string.friends_scores), getResources().getDrawable(android.R.drawable.star_on));
    friendScoresTab.setContent(R.id.ScrollViewFriendScores);
    host.addTab(friendScoresTab);

    host.setCurrentTabByTag("allTab");

Activity_main.xml 包含

<?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="match_parent"
    android:layout_height="match_parent" >

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@+id/scroll" />

        <HorizontalScrollView
            android:id="@+id/scroll"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none"
            android:layout_alignParentBottom="true" >

            <TabWidget

                android:background="@drawable/tabs_bg" />
        </HorizontalScrollView>
    </RelativeLayout>

</TabHost>

java 代码是

TabHost tabHost = getTabHost();

        TabSpec spec;

        Intent intent;

        //Home Tab
        View view1 = LayoutInflater.from(MainActivity.this).inflate(R.layout.home, null);

        intent = new Intent(MainActivity.this, Firstclass.class);

        spec = tabHost.newTabSpec("HOME").setIndicator(view1)
                .setContent(intent);

        tabHost.addTab(spec);

        //Calendar Tab
        View view2 = LayoutInflater.from(MainActivity.this).inflate(R.layout.calendar_tab, null);

        intent = new Intent(MainActivity.this, Calendar.class);

        spec = tabHost.newTabSpec("CALENDAR").setIndicator(view2)
                .setContent(intent);

        tabHost.addTab(spec);
