<LinearLayout 
   xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TabHost
        android:id="@+id/tabHost"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true">

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

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"></TabWidget>

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

                <LinearLayout
                    android:id="@+id/tab1"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:background="#ffc916"
                    android:orientation="vertical">

                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:text="First" />

                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab2"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:background="#da8200"
                    android:orientation="vertical">

                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:text="Second" />
                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab3"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:background="#5b89ff"
                    android:orientation="vertical">

                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:text="Third" />
                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>

</LinearLayout>

Step 2

In MainActivity ,Inside oncreate() method.

1.Create TabHost object using getTabHost().
2.Create tabSpec object.
3.Set Indicator for the Spec.
4.Set Content for the Spec.


These fours steps to achieve tab in android.

Example

TabHost tabhost = getTabHost();
//Tab
TabSpec firstTabSpec = tabHost.newTabSpec("First");
//Set title and icon for the tab
firstTabSpec .setIndicator("First",R.drawable.icon);
Intent firstIntent = new Intent(this,FirstActivity.class);
firstTabSpec.setContent(firstIntent);

//finally add to tabhost
tabhost.addTab(firstIntent);
