在我的应用程序中,我正在开发一个应用程序学生排名系统。
这里,是我之前问过的链接。现在我的要求已满,但我无法访问其中的数据..
public class ListMobileActivity extends ListActivity {
static final String[] MOBILE_OS = new String[] { "001 AAAA", "002 BBBB",
"003 CCCC", "004 DDDD"};
static final String[] MOBILE_OS1 = new String[] { "AAAA", "BBBB",
"CCCC", "DDDD"};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setListAdapter(new ArrayAdapter<String>(this, R.layout.list_mobile,
// R.id.label, MOBILE_OS));
setListAdapter(new MobileArrayAdapter(this, MOBILE_OS));
}
}
和适配器是,..
public class MobileArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
public MobileArrayAdapter(Context context, String[] values) {
super(context, R.layout.list_mobile, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_mobile, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.label1);
TextView textView1 = (TextView) rowView.findViewById(R.id.label);
RadioGroup radioSexGroup=(RadioGroup) rowView.findViewById(R.id.radioSex);
int selectedId = radioSexGroup.getCheckedRadioButtonId();
RadioButton radioSexButton= (RadioButton) rowView.findViewById(selectedId);;
textView.setText(values[position]);
textView1.setText(String.valueOf(position+1));
// Change icon based on name
String s = values[position];
System.out.println(s);
return rowView;
}
}
我可以对这个单选按钮执行任何操作..
现在我的输出屏幕如下...
但是我无法在特定学生的每一行上选择哪个单选按钮,请帮助我实现这一点。我需要使用...更改适配器吗
