Question

我的ListView行为TextView和Switch 现在我希望当我点击First Item Switch时，即当我在Switch（位置== 0）时那么所有下面的行都是可见的当我进行第一次关闭时，所有波纹管行必须被删除全部消失。
我怎么能得到这个......？
默认情况下，switch在Android中是关闭的，这意味着第一次只显示一行，当我在switch上时，所有剩余的行都被添加到第一行以下，反之亦然。
以下代码我使用过：

public class MainActivity extends Activity   
 {
     ListView listView;
     private static final String[] items=
      { "Allow Billing Details Capture", "Address1", "Address2", "City", "State", "Zip",
          "Country", "Email","Phone" };
 static int i;
RelativeLayout Rlmain;
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listview);  
    final ArrayList<String> data=new ArrayList<String>(Arrays.asList(items));
    final TestAdapter adapter=new TestAdapter(this,R.layout.fieldlist,data);
     listView=(ListView)findViewById(R.id.listView1);
    listView.setAdapter(adapter);

}
private void FillList()
{   ArrayList<String> currentdata=new ArrayList<String>();
    ArrayList<String> data=new ArrayList<String>(Arrays.asList(items));
    for(int i=1;i<data.size();i++)
    {
        currentdata.add(data.get(i));
    }
    TestAdapter adapter=new TestAdapter(this,R.layout.fieldlist,currentdata);
    listView.setAdapter(adapter);
    adapter.notifyDataSetChanged();
}
private void fillone() 
{
    ArrayList<String> currentdata=new ArrayList<String>();
    ArrayList<String> data=new ArrayList<String>(Arrays.asList(items));
    currentdata.add(data.get(0));
    TestAdapter adapter=new TestAdapter(this,R.layout.fieldlist,currentdata);
    listView.setAdapter(adapter);
    adapter.notifyDataSetChanged();
}
public class TestAdapter extends ArrayAdapter<String> {
    Context con;
    ArrayList<String> listdata;

    public TestAdapter(Context context, int textViewResourceId,ArrayList<String> myitem) 
    {
        super(context, textViewResourceId, myitem);
        this.con = context;
        this.listdata = myitem;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) 
    {
        LayoutInflater inflater = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            //final View v=convertView;     
        if (convertView == null) 
        {
            convertView = inflater.inflate(R.layout.fieldlist, null);
        }
        TextView data = (TextView) convertView.findViewById(R.id.VTItemTextView);
        Switch check=(Switch)convertView.findViewById(R.id.Vtcheck);
        if(position==0 && check.isChecked())
        {
            FillList();
            notifyDataSetChanged();
        }
        else
        {
            fillone();
            notifyDataSetChanged();
        }
        check.setOnCheckedChangeListener(new OnCheckedChangeListener() 
        {               
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
            {       
                if(isChecked && position==0 )
                {                       
                    FillList();
                    notifyDataSetChanged();                 
                }
                else 
                {
                    fillone();
                    notifyDataSetChanged();
                }

            }
        });
        data.setText(listdata.get(position));
        return convertView;
    }
}
  }

因为它首先只显示一行但在我切换时没有改变。

我认为你真正需要的是像here这样的可扩展列表视图或像here这样的Accordian

开关打开或关闭时修改Listview适配器行
