I have a custom array adapter with 2 textView, 1 spinner and 1 checkbox. When I run my app and select the item in the spinner and scroll the custom adapter the strings in spinner is not stable. It's changing its position in the customAdapter. The code for my getView(),
public class ListAdap extends ArrayAdapter<List> {
private static final String TAG = "ListAdap";
private final ArrayList<List> nameList;
public ListAdap(Context context, int resource, ArrayList<List> list) {
super(context, resource, list);
this.nameList = list;
}
public static class ViewHolder {
ArrayList excuseList;
TextView number;
Spinner excuse;
TextView name;
CheckBox isPaid;
ArrayAdapter adapter;
}
#Override
public View getView(final int position, #Nullable View convertView, #NonNull ViewGroup parent) {
ViewHolder viewHolder = null;
final List currentNameList = getItem(position);
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(
R.layout.pending_list, parent, false);
viewHolder = new ViewHolder();
final ArrayList excuseList = new ArrayList();
excuseList.add("");
excuseList.add("Tommorow");
excuseList.add("Sunday");

ArrayAdapter adapter = new ArrayAdapter(getContext(), android.R.layout.simple_list_item_1, excuseList);
viewHolder.excuse.setAdapter(adapter);
final ViewHolder finalViewHolder = viewHolder;
viewHolder.excuse.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override

currentNameList.get(position).setPos(String.valueOf(pos));
}
#Override

I have a listview with textview and button.
I need to update a textview when a button is clicked in a listview, and hide the button.
When I click the button, it updates the textview value. But when I scroll down and move back up, the textview content is changed back to the previous value and the button is visible.
Customadapter.java
public class CustomAdapter extends BaseAdapter {
ArrayList cusList = new ArrayList();
LayoutInflater inflater;
Context context;
public BookAdapter(Context context, ArrayList cusList) {
this.cusList = cusList;
this.context = context;
inflater = LayoutInflater.from(this.context);
}
#Override
public int getCount() {
return cusList.size();
}
#Override
public Object getItem(int position) {
return cusList.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
Bookdata data = (Bookdata) getItem(position);
viewHolder.mytv.setText(data.getName());
viewHolder.mybtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.setVisibility(View.GONE);
viewHolder.setText("Clicked");
}
});
return convertView;
}
private class ViewHolder {
TextView mytv;
Button mybtn;
public ViewHolder(View item) {
mytv = (TextView)item.findViewById(R.id.mytv);
mybtn = (Button)item.findViewById(R.id.mybtn);
}
}
}
Bookdata.java
public class Bookdata {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Listview Code:
ListView books= (ListView) findViewById(R.id.books);
ArrayList bookList = new ArrayList();
for (int i = 0; i < 10; i++) {
Bookdata data = new Bookdata();
data.setName("position "+i);
bookList.add(data);
}
CustomAdapter allbookAda= new CustomAdapter(context, bookList);
books.setAdapter(allbookAda);
allbookAda.notifyDataSetChanged();
Maintain a flag for each listitem to check which list item has been updated or not.
Basically take one flag value in your model class.
public class Bookdata {
private String name;
private boolean flag;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public boolean isFlag() {
return flag;
}
public void setFlag(boolean flag) {
this.flag = flag;
}
}
add following changes in your getview method
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list, parent, false);
viewHolder = new ViewHolder(convertView);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
Bookdata data = (Bookdata) getItem(position);
viewHolder.mytv.setText(data.getName());
if(data.getFlag){
viewHolder.mybtn.setVisibility(View.GONE);
}
viewHolder.mybtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.setVisibility(View.GONE);
viewHolder.setText("Clicked");
cusList.get(position).setFlag(true);
}
});
return convertView;
}
This is a common behavior as listview uses recycled views, the above answers are correct but I prefer a more cleaner approach using DataBinding

in my android app, i have got an custom table list, where the data will be dynamic filled.
only the first row should a an static row, which i set programmatically.
i have this function to fill my data into the list
private void showList() {
boolean FirstRow = true;
ArrayList<DatabaseListItems> databaseList = new ArrayList<>();
databaseList.clear();
String query = "SELECT * FROM " + DatabaseHelper.DATABASE_TABLE;
Cursor c1 = dbHandler.selectQuery(query);
if (c1.moveToFirst()) {
do {
DatabaseListItems databaseListItems = new DatabaseListItems();
if (c1.getPosition() == 0 && FirstRow == true) {

return convertView;

On the first view, all looks fine.
but if i scroll down and up, random rows get the background color and the onClick function , which only the first row should get.
anyone an idea what i do wrong?
Can you give me an example of passing data from ListView to another ListView.
For example I have my MainActivity.java that has ListView and when i delete item on it. i want to achieve is to pass and add it to another ListView activity.

In your MainActivity you probably have an onItemSelected() listener. In there you can get the item that was removed from the active item list. Assuming you have a field for the deleted items list you would simply call add() on that list with the item you just deleted.
Without some of your actual code that's about as far as we're going to be able to take you ;)
I am android developer, I have a custom listview with a checkbox. This layput also contain a delete button. I want when I click on cheakbox all the item in a particular row is selected and on click of delete it is deleted.
The problem is when I click on delete button I get a list of +1 row value.
Initially I already define :
int position=0;
btmsgdelete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("request send for message delete");
for(Message msg:almsg) {
if(msg.isSelected()) {
CheckBox chk = (CheckBox)findViewById(R.id.checkBox1);
System.out.println("msg is selected");
msgid=almsg.get(position).getEmpid();
System.out.println(msgid);
empname=almsg.get(position).getEmpname();
System.out.println(empname);
msgheader=almsg.get(position).getHeader();
System.out.println(msgheader);
}
}
Try this sample code
public class MainActivity extends Activity {
private int textViewResourceId;

private ListView lst;
#Override

#Override

for (int i = 0; i < searchResults.size(); i++) {
if (searchResults.get(i).getSelected()) {
searchResults.remove(i);
}
}
lst.setAdapter(new Adapter(MainActivity.this, textViewResourceId,
searchResults));
}
});
System.out.println("size " + searchResults.size());
lst.setAdapter(new Adapter(MainActivity.this, textViewResourceId,
searchResults));
}

i have created a listview with checkbox,edittext and textview.
data is populated in listview with sql server. but i am not being able to use onCheckedChangedListener on checkbox. so that on clicking the checkbox corresponding data of textview and edittext is not being saved..
i know i am doing mistake somewhere in my adapter class..
How to save data and what logic should i use in onCheckedChangedListener in my adapter class?

for saving data of textview and EditText what logic should i use and where in Adapter clss i should write it..
May not be a solution, but a suggestion.
Prefer not to declare your Listeners inside an 'if' condition. What I meant is,
IF convertview == null
find views
ELSE
getTag()
Rest of the codes
Is it that your checkbox event is not firing?
I use setOnClickListener for my Checkbox events:
CheckBox checkbox = (CheckBox)view.findViewById(R.id.item_checkbox);
checkbox.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Mark model as selected/not selected
if (model.isSelected())
model.markAsNotSelected();
else
model.markAsSelected();
}

I know it's an old question, but if anyone else is facing same problem, replace the Adapter class with the following code.
public class MyAdapter extends ArrayAdapter<Model> implements TextWatcher{
private final List<Model> list;
private final Context context;
public MyAdapter(Context context, List<Model> list)
{
super(context, R.layout.row, list);
this.context = context;
this.list = list;
}
static class ViewHolder
{
protected TextView text;
protected CheckBox checkbox;
protected EditText scores;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder viewHolder = null;
if (convertView == null){
LayoutInflater inflator = LayoutInflater.from(context);
convertView = inflator.inflate(R.layout.row, null);
viewHolder = new ViewHolder();
viewHolder.text = (TextView) view.findViewById(R.id.label);
viewHolder.scores=(EditText) view.findViewById(R.id.txtAddress);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
viewHolder.checkbox.setTag(list.get(position));
viewHolder.scores.setTag(list.get(position));
convertView.setTag(viewHolder);
}
else
{
convertView = (ViewHolder) convertView.getTag();
}
viewHolder.scores.addTextChangedListener(this)
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
Model element = (Model) viewHolder.checkbox.getTag();
element.setSelected(buttonView.isChecked());
}
});
ViewHolder holder = (ViewHolder) view.getTag();
holder.text.setText(list.get(position).getName());
holder.scores.setText(list.get(position).getScore());
holder.checkbox.setChecked(list.get(position).isSelected());
return view;
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
Model element=(Model)viewHolder.scores.getTag();
element.setScore(s.toString());
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,int after)
{
}
#Override
public void afterTextChanged(Editable s)
{
}
});
}
