I'm trying to test this widget for possible use, but without an example and 
with the given documentation, it's mostly futile.  Currently I get an 
exception: 

java.io.FileNotFoundException: 
res/drawable-hdpi/divider_horizontal_bright_opaque.9.png
07-04

Rather than try to run that down though, since I'm probably doing something 
wrong to begin with.  Can you post some kind of simple example implementation?

What steps will reproduce the problem?
1. Activate a checkbox from the project sample
2. Scroll down 
3. Another checkbox that was previously not checked is now also checked

What is the expected output? What do you see instead?
Only the selected checkbox should be checked. But other checkboxes become also 
checked when scrolling up and down. 

What version of the product are you using? On what operating system?
Currently active version

Can you provide the license text?

Thanks

When I click add an onItemClickListener ass below, it will only get called if 
it's a section being clicked, not if it is a regular row.

Does anyone know how to fix this?

// Create and set adapter
        this.arrayAdapter = new StandardArrayAdapter(this, R.id.artists_list_view_title, this.sectionListItems);
        this.sectionAdapter = new SectionListAdapter(getLayoutInflater(), this.arrayAdapter);
        this.listView = (SectionListView) findViewById(R.id.artists_list_view);
        this.listView.setAdapter(this.sectionAdapter);

        //
        this.sectionAdapter.setOnItemClickListener(new OnItemClickListener()
        {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                Log.d(LOG_TAG, "Clicked.");
            }
        });
        this.listView.setOnItemClickListener(this.sectionAdapter);

What steps will reproduce the problem?

Use as Android Library project, build with ADT14+

What is the expected output? What do you see instead?

Build fails because resource IDs are used in a switch statement. This no longer 
works for library projects starting at ADT 14, see this link: 
http://tools.android.com/tips/non-constant-fields

What steps will reproduce the problem?
1. It does not recognizes which item is clicked.
I set listView.setOnItemClickListener and implemented the OnItemClickListener 
method of android, which simply toasts the item position.
To my surprise, if I tap on the section item, the toast is shown. But it does 
not recognizing the onItemClick for the listView rows.
How to fix this?

What is the expected output? What do you see instead?

I'm trying to add searchbar/seachView for this section list

//============================================================

  private TextWatcher textWatcher = new TextWatcher() {

        public void onTextChanged(CharSequence s, int start, int before, int count) {
            //mArrayAdapter.getFilter().filter(s);

            SectionListActivity.this.arrayAdapter.getFilter().filter(s.toString());

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

        @Override
        public void afterTextChanged(Editable s) {}
    };

//===============================================================

not able to get the required results after entering the text in search bar

I have to implement filters for custom StandardArrayAdapter or 
SectionListAdapter?  

please suggest the search solution for this section list. 

Hi! and thank you for a great library! I works great, even for an android 
newbie like me. This may be an obvious question, but your library is so 
complete, I bet you've even thought of it, so please bear with me...

I'm trying out your sectionlist in a small hobby project of mine, where I 
download data from a json service I've made, that gets updated relatively often 
- several times a day.

I've started out with your:

public class SectionListActivity extends Activity 

and I've added an asynctask that goes something like this:


    private class SectionDownloader extends AsyncTask<String, Integer, Integer>
    {
        protected void onPreExecute(){
            //Setup is done here
        }

        protected Integer doInBackground(String... params) {
                   //populate json array much like your SectionListItem[] exampleArray
                   return Integer length of exampleArray
               } 

        protected void onPostExecute(Integer json_lngth)
        {
            if (json_lngth != null && exampleArray != null)
            {
                arrayAdapter = new StandardArrayAdapter(getApplicationContext(), R.id.example_text_view,
                        exampleArray);
                sectionAdapter = new SectionListAdapter(getLayoutInflater(),
                        arrayAdapter);

                listView = (SectionListView) findViewById(getResources().getIdentifier(
                        "section_list_view", "id",
                        this_package_name));
                listView.setAdapter(sectionAdapter);
            }
            else
            {
                // no network error
            }
        }
        protected void onProgressUpdate(Integer... params){
            //Update a progress bar here, or ignore it, it's up to you
        }

        protected void onCancelled(){
        }

    }

And it works great!


What I am wondering is how to use your option menu to implement a refresh 
button to force a reload of the json array, ie to go out and fetch new data 
from the server and update the list.

I've read about adapter.notifyDataSetChanged() and similar things, but it seems 
to me i have to call the async task first, but when I do that I get an 
exveption like:

08-17 23:21:08.251: E/AndroidRuntime(295): java.lang.NullPointerException
08-17 23:21:08.251: E/AndroidRuntime(295):  at 
pl.polidea.sectionedlist.SectionListAdapter.updateSessionCache(SectionListAdapte
r.java:75)


So as far as I can see something "wrong" happens in your updateSessionCache 
when I do it this way.

What would you suggest the proper way to reload data and update the sectionlist?

Thanks in advance, and sorry if this is a totally inappropriate question...

I tried adding an OnItemClickListener to both the adapter and the 
SectionListView, but neither gets called when I click an item.

I modified the onCreate in the SectionListActivity sample to:

    public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        arrayAdapter = new StandardArrayAdapter(this, R.id.example_text_view, exampleArray);
        sectionAdapter = new SectionListAdapter(getLayoutInflater(), arrayAdapter);
        sectionAdapter.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
              Log.i("test","adapter onclick called");
            }
          });
        final SectionListView listView = (SectionListView) findViewById(getResources().getIdentifier(
                "section_list_view", "id", this.getClass().getPackage().getName()));
        listView.setAdapter(sectionAdapter);
        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
              Log.i("test","view onclick called");
            }
          });
    }

I never get a log message though when I click an item in the list.

Since i'm a beginner i can't figure it out why i'm getting this exception.
i have added 

library_name=pl.polidea.sectionedlist

<uses-library
android:name="@string/library_name"   
android:required="true"/> 

in manifest.xml file and added it as a library also and 
and i have changed the main manifest file as you have indicated in the sample 
to use the sectionListView 

but i'm getting this error:

"java.lang.RunTimeException:Unable to start activity componentInfo 
{pl.polidea.sectionedList/my.package.listActivity}: 
java.lang.NullpointerException"


Android 2.2

i have attached my testing code. please have look at my issue. thanks in 
advance 

What steps will reproduce the problem?
1. Try to attach a header view.
2.
3.

What is the expected output? What do you see instead?
Even though the header view is displayed correctly, the Section view is not 
displayed on the top of the listView, like it does if no other header view are 
attached. 


What version of the product are you using? On what operating system?


Please provide any additional information below.

It seems if i send an empty list to the SectionAdapter, it still shows like a 
default section, named "Section".

I attach an image.

Thanks a lot!

Hi, 

I have a problem with using selector and your section-list. Nomatter how I have 
already try it, I really can't change list view item background. Can you help 
me ? With some easy sample  ? 

        nama = new String[] { "2 Potong Ayam", "Wing Bucket" };

@Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3){

                     Intent i = null;
                if (equals("2 Potong ayam")){
                 i = new Intent(Kfc.this, Ayam.class);
                } else if (equals("Wing Bucket")){
                    i = new Intent(Kfc.this, Bucket.class);
                } startActivity(i);
            }
        });



when i clicked listview,, always force close.

This issue appears when i try to load all the section adapter again.

My app loads the sections and data dynamically, therefore, i can change the 
filters and the data and sections will change.

The problem is that i see in the first section the old section i had, and on 
top of it, the new section (the one with the new data).

The image attached is self descriptive.

To reproduce it (following your example), add a button somewhere, or use the 
menu, and initialize all the data again.
Use another array of data to see the problem clearly.



//on menu button click event, do this
arrayAdapter = new StandardArrayAdapter(this,R.id.example_text_view, 
differentArray);
sectionAdapter = new SectionListAdapter(getLayoutInflater(), arrayAdapter);
final SectionListView listView = (SectionListView) 
findViewById(R.id.section_list_view);
listView.setAdapter(sectionAdapter);

Thanks a lot!

What steps will reproduce the problem?
1. Increasing the list view item height!
2.more time in a list view item
3.or simply when item size expands

What is the expected output? What do you see instead?

Should work normally when section width as it is! but Section header 
visible/change timing changes while item size expands
What version of the product are you using? On what operating system?
Latest

Please provide any additional information below.
in simple line when item in listview expands it will effect the section list 
display/ change timings

What steps will reproduce the problem?
1.Enabled fastscroll by adding "android:fastScrollEnabled="true" in the 
pl.polidea.sectionedlist.SectionListView section of the main.xml layout file. 

2.  Added a few more items to the list to exceed the 35 count
3.  Launched app.  Started manual scrolling. After fastscroll tab appeared, 
attempting to fast scroll by dragging the fastscroll tab resulted in a crash. 

What is the expected output? What do you see instead?
I expected to see the list scrolling quickly.  Instead a crash message 
appeared:  "The application SectionList (process pl.polidea.sectionedlist) has 
stopped unexpectedly.  Please try again."

What version of the product are you using? On what operating system?
This was reproduced on the emulator (2.2 and 2.3) as well as the HTC Sensation.


Please provide any additional information below.
Would appreciate guidance on how to make fastscroll work and also how to have 
the section headers appear in a box as in the alphabetindexer.

Thank you
