如何在android中制作椭圆形tabhost

我试着按照预期的形状制作椭圆形tabhost.

我尝试了以下代码.

public class AndroidTabLayoutActivity extends tabactivity {
    TabHost tabHost;

    @Override
    public void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.main);

        tabHost = getTabHost();
        TabHost.TabSpec spec;
        Intent intent;
        intent = new Intent().setClass(this,PhotosActivity.class);
        View tabView = createTabView(this,"updates");
        spec = tabHost.newTabSpec("tab1").seTinDicator(tabView).setContent(intent);
        tabHost.addTab(spec);

        tabView = createTabView(this,"Events");
        intent = new Intent().setClass(this,SongsActivity.class);
        spec = tabHost.newTabSpec("tab2").seTinDicator(tabView)
                .setContent(intent);
        tabHost.addTab(spec);

        TabWidget tabWidget = (TabWidget) findViewById(android.R.id.tabs);
        final int tabChildrenCount = tabWidget.getChildCount();
        View currentView;
        for (int i = 0; i < tabChildrenCount; i++) {
            currentView = tabWidget.getChildAt(0);
            LinearLayout.LayoutParams currentLayout =
                    (LinearLayout.LayoutParams) currentView.getLayoutParams();
            currentLayout.setMargins(0,16,0);
        }
        tabWidget.requestLayout();
        tabHost.getTabWidget().setDividerDrawable(null);
    }

    private static View createTabView(Context context,String tabText) {
        View view = LayoutInflater.from(context).inflate(R.layout.custom_tab,null,falsE);
        TextView tv = (TextView) view.findViewById(R.id.tabtitleText);
        tv.setText(tabText);
        return view;
    }
}

custom_tab.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://scheR_225_11845@as.android.com/apk/res/android"
android:id="@+id/tabtitleText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:clickable="true"
android:padding="5dp"
android:textSize="15sp"
android:textStyle="bold"
android:layout_gravity="center"
android:ellipsize="marquee"
android:singleLine="true"
android:textColor="@color/tab_textcolor"
android:BACkground="@drawable/tab_SELEctor"/>

我得到的输出如下image70001
