I'm trying to make a context menu for my listview, so when a user long press a row, the context menu shows up, and when the user chooses an option, the row gets selected. However a lot of rows are selected, it repeats the selection in pattern for other rows in the listview.
The same happens when I simply click a row. IDK if it's a problem with view recycling, or what.
How to solve both issues, since first is handled inside onContextItemSelected(MenuItem item)
so I manage the row by manipulating the MenuItem
object, and the second is handled in AdapterView.OnItemClickListener
.
BTW, I'm using CursorAdapter to populate the ListView.
Thanks.
Here is my code:
// Listener for the click on the items in the ListView
mListViewListener = new AdapterView.OnItemClickListener()
{
// When the user clicks some item, the Activity that shows the available dates will be shown
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long arg3)
{
view.setBackgroundColor(0xff333333);
}
};
// Handle the LongClick on the row
@Override
public void onCreateContextMenu(ContextMenu menu, View view, ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, view, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.contact_options, menu);
}
@Override
public boolean onContextItemSelected(MenuItem item)
{
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch(item.getItemId())
{
case R.id.context_menu_item:
info.targetView.setBackgroundColor(0xff333333);
default:
return super.onContextItemSelected(item);
}
}
Something like this in your CursorAdapter should work:
private Set<String> mSelectedContactNumbers = new HashSet<String>();
@Override
public void bindView(View view, Context context, final Cursor cursor)
{
final String contactNumber = cursor.getString(cursor.getColumnIndex("contact_number"));
view.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
if (!mSelectedContactNumbers.remove(contactNumber)) {
mSelectedContactNumbers.add(contactNumber);
}
notifyDataSetChanged();
}
});
if (mSelectedContactNumbers.contains(contactNumber)) {
view.setBackgroundColor(0xff333333);
} else {
view.setBackgroundColor(0);
}
createView(view, cursor);
}
This is just a quick solution. You create a toggleSelected function in the adapter that you can call from OnItemClickListener. That way it will be an little nicer.
