[android-developers] Re: Strange ListView divider behaviour

The code should be the same as in the mentioned tutorial:

***********
List8.java
***********
public class List8 extends ListActivity {

PhotoAdapter mAdapter;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.list_8);

getListView().setEmptyView(findViewById(R.id.empty));

mAdapter = new PhotoAdapter(this);
setListAdapter(mAdapter);

Button clear = (Button) findViewById(R.id.clear);
clear.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
mAdapter.clearPhotos();
}
});

Button add = (Button) findViewById(R.id.add);
add.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
mAdapter.addPhotos();
}
});
}

public class PhotoAdapter extends BaseAdapter {

private Integer[] mPhotoPool = {
R.drawable.sample_thumb_0, R.drawable.sample_thumb_1,
R.drawable.sample_thumb_2,
R.drawable.sample_thumb_3, R.drawable.sample_thumb_4,
R.drawable.sample_thumb_5,
R.drawable.sample_thumb_6, R.drawable.sample_thumb_7};
private ArrayList<Integer> mPhotos = new ArrayList<Integer>();

public PhotoAdapter(Context c) {
mContext = c;
}

public int getCount() {
return mPhotos.size();
}

public Object getItem(int position) {
return position;
}

public long getItemId(int position) {
return position;
}

public View getView(int position, View convertView, ViewGroup
parent) {
ImageView i = new ImageView(mContext);

i.setImageResource(mPhotos.get(position));
i.setAdjustViewBounds(true);
i.setLayoutParams(new
AbsListView.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
i.setBackgroundResource(R.drawable.picture_frame);
return i;
}
private Context mContext;

public void clearPhotos() {
mPhotos.clear();
notifyDataSetChanged();
}

public void addPhotos() {
int whichPhoto = (int) Math.round(Math.random() *
(mPhotoPool.length - 1));
int newPhoto = mPhotoPool[whichPhoto];
mPhotos.add(newPhoto);
notifyDataSetChanged();
}
}
}
