I have a spinner with a checkbox in it, here is the XML for the item:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="10dp">
<CheckBox android:id="@+id/chkBox"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Folder name"
android:textColor="@color/black"
android:soundEffectsEnabled="true"/>
</RelativeLayout>
Here is the adapter code:
public class spAdapter extends BaseAdapter implements OnClickListener {
private ArrayList<String> m_arySelItems = new ArrayList<String>();
private LayoutInflater m_layoutInfater;
private ArrayList<String> m_aryFolders;
public spAdapter(Context context,
int textViewResourceId,
ArrayList<String> aryFolders) {
m_aryFolders = aryFolders;
m_layoutInfater =
(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void add(String item) {
m_aryFolders.add(item);
}
public void clear() {
m_aryFolders.clear();
}
public int getCount() {
return m_aryFolders.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position,
View convertView,
ViewGroup parent) {
View vi = convertView;
try{
// Get the Actual Image from the Array
String strFolder = m_aryFolders.get(position);
if ( vi == null ) {
vi = m_layoutInfater.inflate(R.layout.spfolders, null);
}
CheckBox chkBox = (CheckBox)vi.findViewById(R.id.chkBox);
chkBox.setText(strFolder);
chkBox.setTag(strFolder);
if ( m_arySelItems.contains(strFolder) ) {
chkBox.setChecked(true);
}
chkBox.setOnClickListener(this);
} catch( Exception ex ) {
Log.e( TAG, ex.getMessage() );
}
return vi;
}
@Override
public void onClick(View v) {
CheckBox chkBox = (CheckBox)v;
String strFolder = (String)chkBox.getTag();
if ( chkBox.isChecked() ) {
if ( m_arySelItems.contains(strFolder) == false ) {
m_arySelItems.add(strFolder);
}
} else {
if ( m_arySelItems.contains(strFolder) == true ) {
m_arySelItems.remove(strFolder);
}
}
}
}
I've done something wrong in the getView, something is missing because when
I scroll off view, any selections get mixed up. Is there a good example /
tutorial where I can find out how to implement this correctly?
Thank you,
