Question

在mi布局中我有3个微调器。每个都实现onItemSelectedListener。问题是当我在微调器2上选择一个选项（spinnerSwitches）时，微调器3（spinnerVQs）正在调整自身大小，我不希望这种情况发生。我附上了活动代码，图片和xml布局

的活动：

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);

}

}

我解决了它，您需要做的是为每个包含微调器的线性布局建立一个高度，例如60p，并为每个微调器建立一个小于线性布局的高度，例如50dp
