嗨在下面的代码中,我显示带有复选框的textview.Now当我选择单个值时,它还返回textview的名称和第二个textview名称一样。
现在我想根据复选框选择的值一次返回多个textview名称。 例如:假设两个用户我选择了user1,user2这两个我被选中了我想在单个变量中返回这两个名字。
的java
public class GroupList extends ListActivity
{
boolean[] checkBoxState;
boolean isChecked;
String check;
ListView users;
int position;
private IAppManager imService = null;
private FriendListAdapter friendAdapter;
public String ownusername = new String();
private class FriendListAdapter extends BaseAdapter
{
@SuppressWarnings("unused")
class ViewHolder {
TextView text;
ImageView icon;
CheckBox check1;
}
private LayoutInflater mInflater;
private Bitmap mOnlineIcon;
private Bitmap mOfflineIcon;
private FriendInfo[] friend = null;
public FriendListAdapter(Context context) {
super();
mInflater = LayoutInflater.from(context);
mOnlineIcon = BitmapFactory.decodeResource(context.getResources(), R.drawable.greenstar);
mOfflineIcon = BitmapFactory.decodeResource(context.getResources(), R.drawable.redstar);
}
public void setFriendList(FriendInfo[] friends)
{
this.friend = friends;
}
public int getCount() {
return friend.length;
}
public FriendInfo getItem(int position) {
return friend[position];
}
public long getItemId(int position) {
return 0;
}
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.grouplist, null);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.text);
holder.icon = (ImageView) convertView.findViewById(R.id.icon);
holder.check1 = (CheckBox)convertView.findViewById(R.id.checkBox1);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(friend[position].userName);
holder.icon.setImageBitmap(friend[position].status == STATUS.ONLINE ? mOnlineIcon : mOfflineIcon);
checkBoxState = new boolean[friend.length];
holder.check1.setChecked(checkBoxState[position]);
holder.check1.setOnCheckedChangeListener(new OnCheckedChangeListener(){
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
checkBoxState[position]=isChecked;
if(isChecked){
check=friend[position].userName;
}
Toast.makeText(getApplicationContext(),friend[position].userName+"checked", Toast.LENGTH_LONG).show();
}
});
return convertView;
}
}
答案 0 :(得分:3)
在你的适配器中声明并初始化它......
ArrayList<String> checkedFriends = new ArrayList<String>();
用这个....替换你的点击监听器。
holder.check1.setOnCheckedChangeListener(new OnCheckedChangeListener(){
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
checkBoxState[position]=isChecked;
if(isChecked){
checkedFriends.add(friend[position].userName);
check=friend[position].userName;
} else {
checkedFriends.remove(friend[position].userName);
}
Toast.makeText(getApplicationContext(),checkedFriends.toString()+" checked", Toast.LENGTH_LONG).show();
}
});
