        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if(!(Thread.getDefaultUncaughtExceptionHandler() instanceof ExceptionHandler))
        {
            Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));
        }
        //mlam = new LocalActivityManager(this, false);
        //mlam.dispatchCreate(savedInstanceState);
        myTabHost =(TabHost) findViewById(android.R.id.tabhost);
        myTabHost.setup();

        TabHost.TabSpec login = myTabHost.newTabSpec("tab1");
        TabHost.TabSpec enquiry = myTabHost.newTabSpec("tab2");


        //Below name is display on screen
        login.setIndicator(getResources().getString(R.string.btn_login));
        login.setContent(R.id.tab1);

        enquiry.setIndicator(getResources().getString(R.string.enquiry));
        enquiry.setContent(R.id.tab2);

Solution

See I have made a sample program. But I am using Fragments for tab content-

Class TabActivity.java

import android.os.Bundle;
import android.support.v4.app.FragmentTabHost;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;
import android.widget.TabHost;
import android.widget.Toast;

/**
 * Created by jimitpatel on 14/04/16.
 */
public class TabActivity extends AppCompatActivity implements OnTabEvent {

    private FragmentTabHost tabHost;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tab);

        // create the TabHost that will contain the Tabs
        tabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
        tabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);

        TabHost.TabSpec tab1 = tabHost.newTabSpec("First Tab");
        TabHost.TabSpec tab2 = tabHost.newTabSpec("Second Tab");
        TabHost.TabSpec tab3 = tabHost.newTabSpec("Third tab");

        // Set the Tab name and Activity
        // that will be opened when particular Tab will be selected
        tab1.setIndicator("Tab1");
        tab2.setIndicator("Tab2");
        tab3.setIndicator("Tab3");

        /** Add the tabs  to the TabHost to display. */
        tabHost.addTab(tab1, Tab1Fragment.class, null);
        tabHost.addTab(tab2, Tab2Fragment.class, null);
        tabHost.addTab(tab3, Tab3Fragment.class, null);
    }

    @Override
    public void onButtonClick(String text) {
        if (!TextUtils.isEmpty(text) && null != tabHost) {
            Toast.makeText(getApplicationContext(), text, Toast.LENGTH_LONG).show();

            switch (text) {
                case "Tab1" :
                    tabHost.setCurrentTab(1);
                    break;
                case "Tab2" :
                    tabHost.setCurrentTab(2);
                    break;
                case "Tab3" :
                    tabHost.setCurrentTab(0);
                    break;
            }
        }
    }
}

It's xml file activity_tab.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:id="@+id/LinearLayout01"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

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

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"/>

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

    </LinearLayout>

</android.support.v4.app.FragmentTabHost>

Class Tab1Fragment.java

import android.content.Context;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

public class Tab1Fragment extends Fragment {

    private OnTabEvent mListener;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_tab1, container, false);
        Button button = (Button) view.findViewById(R.id.btn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mListener.onButtonClick("Tab1");
            }
        });
        return view;
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        try {
            mListener = (OnTabEvent) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString() + " must implement OnTabEvent interface");
        }
    }
}

Class Tab2Fragment.java

import android.content.Context;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

public class Tab2Fragment extends Fragment {

    private OnTabEvent mListener;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_tab2, container, false);
        Button button = (Button) view.findViewById(R.id.btn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mListener.onButtonClick("Tab2");
            }
        });
        return view;
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        try {
            mListener = (OnTabEvent) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString() + " must implement OnTabEvent interface");
        }
    }
}

And similarly for Tab3Framgent. TabOnEvent over here is interface which has been implemented in TabActivity and it's callback are used in Fragment classes

Interface TabOnEvent.java

public interface OnTabEvent {
    void onButtonClick(String text);
}

I guess this will suffice for what you were looking for. onButtonClick method is called from Fragment when button is clicked. And interface will ensure it's called back in activity class and then you can change the tab as per your requirement.
