Android AlertDialog ListView w/ several TextViews and an EditText an the end

I'm trying to create an AlertDialog that has many TextViews (so that scrolling in necessary) and an EditText at the end for users to enter a value that is not included in the list. When AlertDialog is first presented, things look good. However, when I scroll back to the top after scrolling to the bottom problems occur.
Here is the bottom of the list initially presented. All good.
But here is what it looks like after I scroll to the top. Not so good.
This is the Adapter class that I am using:
public class MultiSelectOtherDialog extends DialogFragment {
public static final String TAG = "MultiSelectOtherDialog";
private ArrayList<Bean> mList = new ArrayList<>();
public static MultiSelectOtherDialog newInstance(String aTitle, String[] aElems) {
MultiSelectOtherDialog frag = new MultiSelectOtherDialog();
Bundle args = new Bundle();
args.putString("title", aTitle);
args.putStringArray("elems", aElems);
frag.setArguments(args);
return frag;
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// length of this list determines how many items to present - need an extra for the EditText
// at the end for "Other"
int mListLen = (getArguments().getStringArray("elems").length) + 1;
//int mListLen = (getArguments().getStringArray("elems").length);
for (int i = 0; i < mListLen; i++) {
mList.add(new Bean());
}
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
View view = getActivity().getLayoutInflater().inflate(R.layout.scb_listview2, null);
ListView listViewItems = (ListView)view.findViewById(R.id.lvScb);
listViewItems.setAdapter(new MultiSelectOtherAdapter());
listViewItems.setOnItemClickListener(new OnItemClickListenerListViewItem());
builder.setTitle(getArguments().getString("title")).setView(view);
AlertDialog diagFragDialog = builder.create();
return diagFragDialog;
}
public class MultiSelectOtherAdapter extends BaseAdapter {
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
// needed for the "Other" EditText at the end
if (position < mList.size() - 1) {
convertView = View.inflate(getActivity(), R.layout.scb_item, null);
holder.tv = (TextView) convertView.findViewById(R.id.tv);
Log.d(TAG, "1)");
}
else {
convertView = View.inflate(getActivity(), R.layout.scb_item_other, null);
holder.tv = (TextView) convertView.findViewById(R.id.et);
Log.d(TAG, "2)");
}
holder.cb = (SmoothCheckBox) convertView.findViewById(R.id.scb);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
Log.d(TAG, "3)");
}
final Bean bean = mList.get(position);
holder.cb.setOnCheckedChangeListener(new SmoothCheckBox.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(SmoothCheckBox checkBox, boolean isChecked) {
bean.isChecked = isChecked;
}
});
// needed for the "Other" EditText at the end
if (position < getArguments().getStringArray("elems").length) {
String text = getArguments().getStringArray("elems")[position];
holder.tv.setText(text);
Log.d(TAG, "4)");
}
else {
convertView = View.inflate(getActivity(), R.layout.scb_item_other, null);
holder.tv = (TextView) convertView.findViewById(R.id.et);
holder.cb = (SmoothCheckBox) convertView.findViewById(R.id.scb);
convertView.setTag(holder);
Log.d(TAG, "5)");
}
holder.cb.setChecked(bean.isChecked);
Log.d(TAG, "6)");
return convertView;
}
class ViewHolder {
SmoothCheckBox cb;
TextView tv;
}
}
public class OnItemClickListenerListViewItem implements AdapterView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Bean bean = (Bean) parent.getAdapter().getItem(position);
bean.isChecked = !bean.isChecked;
SmoothCheckBox checkBox = (SmoothCheckBox) view.findViewById(R.id.scb);
checkBox.setChecked(bean.isChecked, true);
}
}
class Bean implements Serializable {
boolean isChecked;
}
}

In your adapter change this:
#Override
public long getItemId(int position) {
return position;
}
And, also in your getView() method, put this code:
converView = null;
before :
if(convertView == null){
// your codes
}

Remove selected dynamic checked items from listview

Here, in a listview I have added a custom row in which Checkbox and EditText are there and with a add button I just add multiple views to my listview. Adding is working perfectly but when it comes to removing part the checked items are not removing and apart from that suppose I selected two items, then two items from last deleted. I don't know whats going on with my code please help me.
Here is my code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
AdapterCustom customAdapter;
ArrayList<String> stringArrayList;
ListView listView;
ArrayList<Integer> listOfItemsToDelete;
AdapterCustom.ViewHolder item;
int POS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listOfItemsToDelete = new ArrayList<Integer>();
stringArrayList = new ArrayList<String>();
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
listView = (ListView) findViewById(R.id.list_item);
customAdapter = new AdapterCustom(MainActivity.this, R.layout.main, stringArrayList);
}
public void addItems(View v) {
stringArrayList.add("");
listView.setAdapter(customAdapter);
customAdapter.notifyDataSetChanged();
}
public void removeItems(View v) {
if (listOfItemsToDelete.isEmpty()) {
Toast.makeText(getBaseContext(), "No items selected.",
Toast.LENGTH_SHORT).show();
} else {
Log.i("Delete Pos", POS + "");
if (!listOfItemsToDelete.equals("")) {
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
}
}
}

super(context, resourceId, arrayList);
this.context = context;
this.stringArrayList = arrayList;
positionArray = new ArrayList<Boolean>(stringArrayList.size());
for (int i = 0; i < stringArrayList.size(); i++) {
positionArray.add(false);
}
activity = new MainActivity();
}
#Override
public int getCount() {
return stringArrayList.size();
}
#Override
public String getItem(int position) {
return stringArrayList.get(position);
}
#Override

return position;
}
public class ViewHolder {
EditText ediText;
CheckBox checkBox;
}
#Override

if (convertView == null) {
item = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.main, null);
item.ediText = (EditText) convertView.findViewById(R.id.ediText);
item.checkBox = (CheckBox) convertView.findViewById(R.id.checkBox);
item.checkBox.setTag(new Integer(position));
convertView.setTag(item);
final View finalConvertView1 = convertView;
item.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override

if (b) {
int getPosition = (Integer) compoundButton.getTag();
POS = getPosition;
listOfItemsToDelete.add(POS);
Log.i("position after check", POS + "");
Log.i("position check array", listOfItemsToDelete + "");
}
}
});
} else {

}
item.checkBox.setTag(position);
return convertView;
}

You only remove the item from the array. Try removing the item also from the list view adapter with adapter.remove(itemPosition);

What does mean
- j
in this code:
for (int j = 0; j < listOfItemsToDelete.size(); j++) {
stringArrayList.remove(listOfItemsToDelete.get(j) - j);
customAdapter.notifyDataSetChanged();
}
?
I think that:
for (String itemToRemove:listOfItemsToDelete) {
stringArrayList.remove(itemToRemove);
}
customAdapter.notifyDataSetChanged();
listOfItemsToDelete.clear();
would be appropriate.

Section Indexer does not show in listview

My Custom adapter is as follows:-
public class ListAdapter extends ArrayAdapter<Person> implements SectionIndexer {
private HashMap<String, Integer> alphaIndexer;
private String[] sections;
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
}
public ListAdapter(Context context, int resource, ArrayList<Person> items) {
super(context, resource, items);
alphaIndexer = new HashMap<String, Integer>();
for (int i = 0; i < items.size(); i++)
{
Log.d("State",items.get(i).getState().substring(0, 1).toUpperCase());
String s = items.get(i).getState().substring(0, 1).toUpperCase();
alphaIndexer.put(s, i);
}
Set<String> sectionLetters = alphaIndexer.keySet();
ArrayList<String> sectionList = new ArrayList<String>(sectionLetters);
Collections.sort(sectionList);
sections = new String[sectionList.size()];
sectionList.toArray(sections);
}
public int getPositionForSection(int section)
{
return alphaIndexer.get(sections[section]);
}
public int getSectionForPosition(int position)
{
return 1;
}
public Object[] getSections()
{
return sections;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.bystate_itemview, null);
}
Person p = getItem(position);
if (p != null) {
ImageView im1= (ImageView) v.findViewById(R.id.legislator_image);
TextView tt1 = (TextView) v.findViewById(R.id.firstname);
TextView tt2 = (TextView) v.findViewById(R.id.details);
ImageView im2 = (ImageView) v.findViewById(R.id.getDetails);
if (im1 != null){
String url = p.getImage();
Picasso.with(getContext()).load(url).fit().centerCrop().into(im1);
}
if (tt1 != null) {
String name= p.getLastname()+", "+p.getFirstname();
tt1.setText(name);
}
if (tt2 != null) {
String details="";
if(p.getDistrict()!="NA")
details= "("+p.getParty()+")"+p.getState()+" - "+"District "+p.getDistrict();
else
details= "("+p.getParty()+")"+p.getState()+" - "+"District 0";
tt2.setText(details);
}
if (im2 != null) {
Drawable myDrawable = getResources().getDrawable(R.drawable.right);
im2.setImageDrawable(myDrawable);
}
}
return v;
}
}
I have implemented this custom adapter following a tutorial. I have implemented the section indexer. But the issue is that the section indexer does not show up in the app. I am trying to index stuff based on the first letter of each state of the person. I want the alphabetical list to show up in the list view so that when I tap on a particular letter it must show persons belonging to that state.

Please let me know if I am missing something. This is my first custom adapter so I may be doing something wrong.

Just use below structure ,Mayi know why youimplement sectionIndex
public class CustomeAdapter extends BaseAdapter {
#Override
public int getCount() {
return 0;
}
#Override
public Object getItem(int i) {
return null;
}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
return null;
}
}

Check all checkboxes in custom list view

I currently have ListFragment with a ArrayAdapter class
The codes are below.
1)I want to implement a checkbox from listview main xml to check all the checkboxes that are present in custom list row xml which is inflated using Array adapter.
2)how to refresh view in this code by clearing all checkboxes when a button is clicked.

setadapter for android not working. empty adapter or listview?

im just trying to create a listview using a simple adapter. the setadapter is not working. this is my code. my setcontentview is before this block of code and this is in oncreate.
ArrayList<HashMap<String,String>> arraylist = new ArrayList<HashMap<String,String>>();
HashMap<String,String> map = new HashMap<String,String>();
map.put("CType", "Alarm");
map.put("RType", "Once");
map.put("hour", "1");
map.put("minute", "1");

Here's an example of a custom adapter. Try this ...
public class ClockListAdapter extends BaseAdapter {
ArrayList<HashMap<String, String>> _arrayList;
ClockListAdapter(Context context, ArrayList<HashMap<String, String>> arrayList) {
this._arrayList = arrayList;
}
#Override
public int getCount() {
return (_arrayList != null) ? _arrayList.size() : 0;
}
#Override
public Object getItem(int position) {
return (_arrayList != null) ? _arrayList.get(position) : null;
}
#Override
public long getItemId(int position) {
return (_arrayList != null) ? _arrayList.indexOf(_arrayList.get(position)) : 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
// REPLACE WITH YOUR LAYOUT FILE vvvvvvvvvv
convertView = layoutInflater.inflate(android.R.layout.simple_list_item_1, null);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder._textView.setText("set some text here");
return convertView;
}
public class ViewHolder {
// ADD YOUR VIEW(S) vvvvvvvvv
TextView _textView;
ViewHolder(View v) {
// REPLACE WITH YOUR TEXT vvvvvvvvv
_textView = (TextView) v.findViewById(R.id.textView1);
}
}
}
