本次设计的思想是利用listview的item单击动作控制RadioButton的显示

mail.xml

 

item.xml:在item行的样式设计中，最重要的是要阻断item中控件的事件android:descendantFocusability="blocksDescendants"；并且将RadioButton的clicable设置为false。

 .java

private int clickPosition = -1;

@Override        public View getView(int arg0, View arg1, ViewGroup arg2) {            // TODO Auto-generated method stub            ViewHolder holder = null;            if (arg1 == null) {                holder = new ViewHolder();                arg1 = mInflater.inflate(R.layout.chooselanguage_item, null);                holder.title = (TextView) arg1.findViewById(R.id.title);                holder.RadioBtn = (RadioButton) arg1                        .findViewById(R.id.radiobutton);                arg1.setTag(holder);            }           holder = (ViewHolder) arg1.getTag();                        holder.title.setText((String) mData.get(arg0).get("title"));            // holder.RadioBtn.setChecked((Boolean)mData.get(arg0).get("choice"));            if (clickPosition == arg0) {                holder.RadioBtn.setChecked(true);                            } else {                holder.RadioBtn.setChecked(false);                            }                                    return arg1;        }    }

@Override    public void onItemClick(AdapterView
      arg0, View arg1, int arg2, long arg3) {        // TODO Auto-generated method stub        clickPosition = arg2;         mAdapter.notifyDataSetInvalidated();    }
