How to make oval shape tabhost in android

Question

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;
    }
}

main.xml

        </LinearLayout>
    </TabHost>
</LinearLayout>

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

Answer 1

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>

Answer 2

try this in your xml.and use it as a tab.

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

  <corners
    android:bottomLeftRadius="30dp"
    android:bottomRightRadius="30dp"
    android:radius="60dp"
    android:topLeftRadius="30dp"
    android:topRightRadius="30dp" />

  <solid android:color="#CFCFCF" />

  <padding
    android:bottom="0dp"
    android:left="0dp"
    android:right="0dp"
    android:top="0dp" />

  <size
    android:height="60dp"
    android:width="270dp" />

</shape> 

Answer 3

you can make oval tabs by using drawables in tabhost. please find the code snippets below

tabHost.newTabSpec("tab1").setIndicator(getCustomLayout()).setContent(intent);

private static View getCustomLayout(Context context, String tabText) { View view = LayoutInflater.from(context).inflate(R.drawable.custom_tab,null, false); return view; }

custom-tab.xml

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
     android:shape="oval">
     <stroke
         android:width="1dp"
         android:color="#000000"/>
       <corners android:radius="2dp"/>
    </shape>
