我有一个Android表单,需要根据某些选择更新自己.该表格目前由2个Spinners(A和B)组成.在完成Spinner A的选择之前,不会创建微调器B. 选择完成后,B将显示在视图中,并根据A的选择动态填充内容.这是我的代码:

public class MyForm extends Activity 
{   
    private final int SEL_ACTIVATE = 0;
    private final int SEL_DEACTIVATE = 1;

    private static final String[] actionList = {"Activate", "Deactivate" };

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        table = (TableLayout) findViewById(R.id.table);

        showListA(table);
    }

    public void showListA(View v)
    {        
        rowAction = new TableRow(this);

        Spinner spinner = new Spinner(this);
        spinner.setPrompt("Select...");
        spinner.setOnItemSelectedListener(
            new OnItemSelectedListener() 
            {
                public void onItemSelected(AdapterView<?> parent, View v, int position, long id) 
                {
                    switch (position)
                    {
                    case SEL_ACTIVATE:
                    case …
