Android Spinner resizing when selecting

Question

In mi layout I have 3 spinners. Each one implements onItemSelectedListener. The problem is when I select an option on spinner number 2 (spinnerSwitches) the spinner number 3 (spinnerVQs) is resizing itself, and i don´t want that to happen. I attached, Activity code, images, and xml layout

Activity:

public class CCHawkResourcesActivity extends Activity {

private Spinner spinnerTenants;
private Spinner spinnerSwitches;
private Spinner spinnerVQs;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_cchawk_resources);
    vincularControles();
    Sesion.setUsuarioActual(RetornaLogica.GetInstance().getIl().TraerUsuarios().get(0));
    Tenant selectedTenant=new Tenant(Sesion.getUsuarioActual().getConfig().getSelectedTenant());



    ArrayAdapter<Tenant> a=new ArrayAdapter<Tenant>(this,R.layout.spinner_dropdown_item,Sesion.getListaTenants());
    a.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinnerTenants.setAdapter(a);
    if(!selectedTenant.getNombre().equals(""))spinnerTenants.setSelection(a.getPosition(selectedTenant));
    spinnerTenants.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View selectedView,int position, long id) {

            Tenant t=((Tenant)spinnerTenants.getSelectedItem());
            Switch selectedSwitch=new Switch(Sesion.getUsuarioActual().getConfig().getSelectedSwitch());
            ArrayAdapter<Switch> b=new ArrayAdapter<Switch>(CCHawkResourcesActivity.this,R.layout.spinner_dropdown_item,t.getListaSwitch());
            b.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            spinnerSwitches.setAdapter(b);
            if(!selectedSwitch.getNombre().equals(""))spinnerSwitches.setSelection(b.getPosition(selectedSwitch));
            spinnerSwitches.setOnItemSelectedListener(new OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View selectedView,int position, long id) {

                    Switch s=((Switch)spinnerSwitches.getSelectedItem());
                    VirtualQueue selectedVQ=new VirtualQueue(Sesion.getUsuarioActual().getConfig().getSeletedVQ());

                    ArrayAdapter<VirtualQueue> c=new ArrayAdapter<VirtualQueue>(CCHawkResourcesActivity.this,R.layout.spinner_dropdown_item,s.getListaVQ());
                    c.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                    spinnerVQs.setAdapter(c);
                    if(!selectedVQ.getNombre().equals(""))spinnerVQs.setSelection(c.getPosition(selectedVQ));
                    spinnerVQs.setOnItemSelectedListener(new OnItemSelectedListener() {

                        @Override
                        public void onItemSelected(AdapterView<?> parent, View selectedView,int position, long id) {}

                        @Override
                        public void onNothingSelected(AdapterView<?> arg0) {}
                    });


                }

                @Override
                public void onNothingSelected(AdapterView<?> arg0) {}
            });

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {}
    });


}

private void vincularControles(){

    spinnerTenants=(Spinner)findViewById(R.id.spinnerTenants);
    spinnerSwitches=(Spinner)findViewById(R.id.spinnerSwitches);
    spinnerVQs=(Spinner)findViewById(R.id.spinnerVQs);

}

}

Answer 1

I solved it, the thing you need to do is establish a height por each one of the linear layout containing the spinners, for example 60p, and establishing for each spinner a height smaller than the linear layout, for example 50dp
