Edit: Okay, I found a solution. Don't know that it's the proper solution, but it does work correctly. Added to the code below.
I'm trying to allow a user to select a number of directories from a checklist, and return them upon clicking a "Submit" button. Here's a snippet of my code. It populates the ListView with all the directories on /sdcard/, and for the initial selection (of however many I pick) when I submit, the log shows the correct choices returned. However, if I uncheck an item, and click "Submit" again, it still shows as if all are selected. Do I need to write a handler to uncheck an item? I thought that was taken care of by the choiceMode selection? Thanks!
private SparseBooleanArray a;
directoryList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, directoryArray));
submitButton = (Button)findViewById(R.id.submit_button);
submitButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
a = new SparseBooleanArray();
a.clear();
a = directoryList.getCheckedItemPositions();
for (int i = 0; i < a.size(); i++)
{
//added if statement to check for true. The SparseBooleanArray
//seems to maintain the keys for the checked items, but it sets
//the value to false. Adding a boolean check returns the correct result.
if(a.valueAt(i) == true)
Log.v("Returned ", directoryArray[a.keyAt(i)]);
}
}
});
