我有一个简单的ArrayAdapter.我想为列表的每一行点击设置一个监听器,以便打开一个新的Activity.我该怎么办？我的ArrayAdapter代码 –
- public class CountryListAdapter extends ArrayAdapter<String> {
- private final Activity context;
- private final ArrayList<String> names;
- public CountryListAdapter(Activity context,ArrayList<String> names) {
- super(context,R.layout.rowlayout,names);
- this.context = context;
- this.names = names;
- }
- @Override
- public View getView(int position,View convertView,ViewGroup parent) {
- LayoutInflater inflater = context.getLayoutInflater();
- View rowView = inflater.inflate(R.layout.rowlayout,null,true);
- TextView textView = (TextView) rowView.findViewById(R.id.label);
- textView.setText(names.get(position));
- return rowView;
- }
解决方法
假设您正在使用ListActivity实现OnItemClickListener
你可以使用这段代码：
你可以使用这段代码：
- ArrayAdapter<Object> ad = new ArrayAdapter<Object>(this,android.R.layout.simple_list_item_checked,items);
- setListAdapter(ad);
- ListView list = getListView();
- list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
- //list.setItemChecked(0,true);
- list.setOnItemClickListener(this);
编辑：
否则,如果不扩展ListActivity,请在布局中使用listview,并使用ListView list = findViewById(R.id.listView)替换ListView list = getListView().用.替换list.setOnItemClickListener(this)
- list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
- @Override
- public void onItemClick(AdapterView<?> parent,View view,int position,long id) {
- }
- });
