How to make oval shape tabhost in android

I tried to make oval shape tabhost as expected below shape.

I tried the below codes.

    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, 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;
    }
}

        </LinearLayout>
    </TabHost>

custom_tab.xml

android:textStyle="bold"
android:layout_gravity="center"
android:ellipsize="marquee"
android:singleLine="true"
android:textColor="@color/tab_textcolor"
android:background="@drawable/tab_selector"/>

I got the output as below image

Can anyone help, how to make it. Thanks

Well that's an image.All what you need to do is ready the images and set them to the selected tab.That's it!

Well I don't have that image, so I used below images(_selected.png,_{not_selected.png}) just to show how it works but they are not well designed ;)

P.s currentLayout.setMargins(0, 0, this_should_be_zero, 0); and your images should have that margins(whatever the expected gap) otherwise there will be a gap between two images. Additionally you can use selector(same png with another color) to show the selected one.

_{Seems you are trying to figure out a programmatic way try workaround with Paint class if you got extra time & effort,if you use shapes will be hard to figure out the exact view since it is complicated, you can see tab A view and B is not same,using an image will be the easiest}

And in your custom_tab.xml set

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.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:MaxLines="1"   //  you can use this instead  of  android:singleLine="true" 
    android:textColor="@color/black"
    android:background="@drawable/tab_button_effect"/> // here set selector

tab_button_effect.xml

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

    <item android:drawable="@drawable/not_selected" android:state_selected="true"></item>
    <item android:drawable="@drawable/selected"></item>

</selector>
