public void onButtonTabClick(View v) { Fragment fragment = null; switch (v.getId()) { case R.id.button_equipment: fragment = new EquipmentFragment(); break; case R.id.button_tech: fragment = new TechnicianFragment(); break; case R.id.button_timeline: fragment = new TimeLineFragment(); break; } } — Mohsin, Aug 16 '18 at 11:57

You just need to write specific code for setting background color of buttons.

public void onEquipmentPressed(){
    equipmentButton.setBackgroundColor(getResources().getColor(R.color.color_id));
    technicans.setBackgroundColor(getResources().getColor(R.color.default_color_id));
    timeline.setBackgroundColor(getResources().getColor(R.color.default_color_id));

}


public void onTechnicansPressed(){
    equipmentButton.setBackgroundColor(getResources().getColor(R.color.default_color_id));
    technicans.setBackgroundColor(getResources().getColor(R.color.color_id));
    timeline.setBackgroundColor(getResources().getColor(R.color.default_color_id));

}

and so on

You don't need to declare many method to handle button's state like @Asset Bekbossynov. You can write code in this way:

private View mLastClickView;
public void onButtonTabClick(View v)
{
    // add these code
    if (mLastClickView != null) {
        mLastClickView.setBackgroundColor(getResources().getColor(R.color.unselected));
    }
    v.setBackgroundColor(getResources().getColor(R.color.selected));
    mLastClickView = v;

    Fragment fragment = null;
    switch (v.getId())
    {
        case R.id.button_equipment:
            fragment = new EquipmentFragment();

            break;
        case R.id.button_tech:

            fragment = new TechnicianFragment();

            break;

        case R.id.button_timeline:
            fragment = new TimeLineFragment();

            break;
    }

    FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction transaction = manager.beginTransaction();
    transaction.replace(R.id.show_fragment, fragment);
    transaction.commit();
}

why you use fragments? does he asked about it or did I understand something wrong? — Asset Bekbossynov, Aug 16 '18 at 12:06
He wants to click button to change fragment, and change buttons state like tablayout. You can have a look for his question, he added the code just now. — orzangleli, Aug 16 '18 at 12:10
