Hi all,
I'm having an issue with the ListView in Android.
So I have an activity extending the ListActivity, in the activity I
have an innerclass for my adapater.
Now both on my device and the emulator some entries appear 2 or 3
times in the list (not always the same items) although the size of my
List<Label> is always the same!
On the emulator I noticed that it's mostly related to the scrolling in
the list... If I scroll down some entries are duplicate, if I scroll
up and down again the entries have changed all over the list...
Is there anything in my code that you guys can see that is wrong?
Here's my code:
....
this.labels = labelService.findAll();
Collections.sort(this.labels, new LabelByNameComparator());
Log.d(LOG_TAG, labels.size() + " labels loaded!");
ManageLabelsListAdapter adapter = new
ManageLabelsListAdapter(labels);
adapter.notifyDataSetChanged();
setListAdapter(adapter);
/**
* The list adapater private inner-class used to display the
manage labels list.
*/
private class ManageLabelsListAdapter extends ArrayAdapter<Label>
{
private final String LOG_TAG =
ManageLabelsListAdapter.class.getSimpleName();
/**
* {@inheritDoc}
*/
public ManageLabelsListAdapter(List<Label> labels) {
super(ManageLabelsActivity.this,
R.layout.list_item_labels, labels);
Log.d(LOG_TAG, "Creating the manage labels list
adapater");
}
@Override
public View getView(int position, View convertView, ViewGroup
parent) {
Log.d(LOG_TAG, "Getting view...");
View row = convertView;
ManageLabelsListWrapper wrapper;
if(row == null) {
Log.d(LOG_TAG, "Row needs to be created!");
final Label label = labels.get(position);
Log.d(LOG_TAG, "Label at list position " + position +
" retrieved from DB list: " + label);
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.list_item_labels,
parent, false);
Log.d(LOG_TAG, "Label row inflated into layout!");
wrapper = new ManageLabelsListWrapper(row);
Log.d(LOG_TAG, "Row wrapped!");
TextView labelName = wrapper.getLabelname_listitem();
Log.d(LOG_TAG, "About to update the name of the label
in the view for TextView " + labelName + " with the value: " +
label.getName());
labelName.setText(label.getName());
ImageView deleteButton = wrapper.getBtn_delete();
deleteButton.setOnClickListener(new
View.OnClickListener() {
public void onClick(View view) {
deleteLabel(label, true);
}
});
}
return row;
}
}
