问题描述
我创建了一个简单的ListView包括checkedTextView。
I created a simple ListView includes checkedTextView.
我想添加一个监听器时的ListView行的用户点击,
I want to add a listener when user click on listView row,
1 - TextView的成为检查。
1 - The textView become checked.
2 - 如果存在,其中分别检查列表中的其他的TextView,成为未检查
2 - If there is another textview in the list which were checked, become unchecked.
这是code这是我写的到现在为止:
This is the code which I written until now:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ArrayList<String> mStrings = new ArrayList<String>();
for(int i=0; i<30; i++) {
mStrings.add("Item " + i);
}
setListAdapter( new MultiAdapter(this, mStrings));
/* Configure ListView */
ListView lv = getListView();
lv.setOnItemClickListener(new ItemClick());
}
class ItemClick implements OnItemClickListener {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
}
private class MultiAdapter extends ArrayAdapter<String> {
private ArrayList<String> mItems;
public MultiAdapter(Context context, ArrayList<String> mStrings) {
super(context, R.layout.list2, mStrings);
this.mItems = mStrings;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row;
if (convertView == null) {
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.list2, parent, false);
} else
row = convertView;
CheckedTextView txt = (CheckedTextView) row.findViewById(R.id.label);
txt.setText(mItems.get(position));
return row;
}
}

推荐答案
如果你只想最多1在任何检查都给予时间,那么你可以做到以下几点:
If you want to have only max 1 checked in any give time then you can do following:
- 创建
INT checkedItem;
属性。此属性显示当前选中项目的索引。 -1,如果没有被选中。 - 在
项目单击
刚刚成立checkedItem =位置
。并调用getListAdapter()。notifyDataSetChanged()
。 - 在
getView
添加txt.setChecked(位置== checkedItem)
。
- Create
int checkedItem;
property. This property show index of currently checked item. -1 if none is checked. - In
ItemClick
just setcheckedItem = position
. And callgetListAdapter().notifyDataSetChanged()
. - In
getView
addtxt.setChecked(position == checkedItem)
.
