One way of doing this can be by implementing the OnClickListener.

public class Tab_1st extends Activity implements OnClickListener {

Button button1A;
Button button2A;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tablayout1);
    button1A = (Button) findViewById(R.id.button1A);
    button2A = (Button) findViewById(R.id.button2A);
    button1A.setOnClickListener(this);
    button2A.setOnClickListener(this);
}

@Override
public void onClick(View v) {
    if (v == button1A) {
        // Start Activity a1
        Intent a1 = new Intent(v.getContext(), List1.class);
        startActivity(a1);
    } else if (v == button2A) {
        // Start Activity a2
        Intent a2 = new Intent(v.getContext(), List2.class);
        startActivity(a2);
    }

}

}
