我有一个动态单选按钮的列表视图(它将基于listview中的一些问题的大小创建,即,对于第一个问题我有4个单选按钮第二个问题可能有3个单选按钮.....)。我的问题当用户选择使用单选按钮选择答案时,我需要提交这些表格。那么如何实现这些列表视图数据以及选定的答案。另外我需要检查问题是否得到回答(意味着检查无线电组)。当我提交时,我想要整个数据。任何人都可以帮助我。
这是我的getview
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
final ViewHolder viewHolder = new ViewHolder();
view = View.inflate(mContext, R.layout.item_list_bradenscale_entry, null);
viewHolder.txtQuestionHeadName = (TextView) view.findViewById(R.id.textview_question_name);
viewHolder.radioGroup = (RadioGroup) view.findViewById(R.id.radio_group);
viewHolder.radioButtonOption1 = (RadioButton) view.findViewById(R.id.radio1);
viewHolder.radioButtonOption2 = (RadioButton) view.findViewById(R.id.radio2);
viewHolder.radioButtonOption3 = (RadioButton) view.findViewById(R.id.radio3);
viewHolder.radioButtonOption4 = (RadioButton) view.findViewById(R.id.radio4);
viewHolder.txtQuestionHeadHint = (TextView) view.findViewById(R.id.textview_question_hint);

}
viewHolder.radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

在适配器 getView()方法中,在呈现列表项时将侦听器附加到单选按钮。在on checked事件中,更改对象的属性。您的活动只能访问相同的对象列表并检索最新的问卷状态。
rGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
public void onCheckedChanged(RadioGroup group, int checkedId)
{
// This will get the radiobutton that has changed in its check state
RadioButton checkedRadioButton = (RadioButton)group.findViewById(checkedId);
// This puts the value (true/false) into the variable
boolean isChecked = checkedRadioButton.isChecked();
// If the radiobutton that has changed in check state is now checked...
if (isChecked)
{
//Change your object's attribute here
question.answer = "xxxx";
}
}
});
