I want to display Two Listview in my Projects.I am passing using a single adapter to set the contents of two listviews.If I pass array of same length for both listviews to adapter,then it works fine,But If I pass Array of Different Length for Different listview in the adapter,My Application Force closes with the Error:-
>java.lang.ArrayIndexOutOfBoundsException: length=2; index=2

And I setting the adapter in Listview as:-
ArrayList<String> items_transmission = new ArrayList<String>();
items_transmission.add("Automatic");
items_transmission.add("Manual");
adapter1 = new DropDownListAdapter(DropDownListDemo.this, items_transmission);
transmisson_type.setAdapter(adapter1);
ArrayList<String> items = new ArrayList<String>();
items.add("Cars");
items.add("Passenger Van");
items.add("SUV");
adapter = new DropDownListAdapter(DropDownListDemo.this, items);
list.setAdapter(adapter);
Please help me...?
I think the problem is with this part.
if(DropDownListDemo.car_type)
{
if(DropDownListDemo.checkSelected_cartype[position])
holder.chkbox.setChecked(true);
else
holder.chkbox.setChecked(false);
}
else
{
if(DropDownListDemo.checkSelected_transmissontype[position])
holder.chkbox.setChecked(true);
else
holder.chkbox.setChecked(false);
}
When you call that code for 2 listviews in a row, the value of DropDownListDemo.car_type probably doesn't change so it goes into the same part (second) for both listview. Is that right?
Try to return mListItems.get(arg0) in getItem(arg0) method
public DropDownListAdapter(Context context, ArrayList<String> items) {
mListItems = items;
mInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return mListItems.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return mListItems.get(arg0);
}

I have created a custom listview adapter to fit a button, a custom chronometer and a textview. When i scroll my listview, the rows that are "hidden" refresh themselves and so chronometers, how can i keep chronometers running even if they're hidden?
I am quite new to Android development so i may have done something wrong; I know that listview refresh its rows when scrolled but maybe there's something that i missed to make chronometers running in background
public class MyCustomAdapter extends BaseAdapter {
ArrayList<String> users;
Context context;
LayoutInflater inflater = null;
public MyCustomAdapter(Activity mainActivity, ArrayList<String> usersList) {
// TODO Auto-generated constructor stub
users = usersList;
context = mainActivity;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return users.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return users.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
private class Holder {
TextView tv;
CustomChrono cr;
Button but;
}
#Override
public View getView(final int position, View convertView, final ViewGroup parent) {
// TODO Auto-generated method stub
final Holder holder = new Holder();
View rowView;
rowView = inflater.inflate(R.layout.customized_list_view, null);
holder.tv = (TextView) rowView.findViewById(R.id.names_laps);
holder.cr = (CustomChrono) rowView.findViewById(R.id.chronometer_laps);
holder.but = (Button) rowView.findViewById(R.id.stop_button);
holder.cr.start();
holder.but.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//((ListView) parent).performItemClick(v, position, 0);
holder.cr.stop();
stopped = true;
}
});
holder.tv.setText(users.get(position));
rowView.setTag(holder);
return rowView;
}
}
Then I have my activity class where I use this adapter

{
runners_arrList.add(new Runner(r));
}
for (int f = 0; f < runners_arrList.size();f++)
{
Log.d("Runner: " + f,runners_arrList.get(f).getName());
}
m = getIntent().getExtras().getString("booly");
for (int j = 0; j < runner_array.size(); j++) {
Runner r = new Runner(runner_array.get(j));
map.put(r, runner_array.get(j));
}
if (m!= null)
{
stopped = true;
}
list = (ListView) findViewById(R.id.laps_list);
final MyCustomAdapter adapter = new MyCustomAdapter(RunnerLaps.this,runner_array);
list.setAdapter(adapter);
//addRunners();
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override

r = runners_arrList.get(position);
r.setTemp(System.currentTimeMillis());
long temp = r.getTemp();
previousClickTime1 = temp;
if (previousClickTime1 != 0 && previousClickTime1 - temp < 300)
{
if (stopped == true)
{
chr.stop();
r.laps[r.counter] = chr.getText().toString();
r.increaseCounter();
Intent i = new Intent (RunnerLaps.this,Runner_Display.class);
i.putExtra("key",(Serializable) r);

}

}
else

r.increaseCounter();
for (int h = 0; h < runner_array.size();h++)
{
System.out.println(runners_arrList.get(h).getName() + "\n");
System.out.println(runners_arrList.get(h).laps[0] + "\n");

}
}
}

This Is my Adapter problem was scroll listview to change textview value by every position how to solve it ? plus click event to increment one and minus event to decrment and set value in textview (Plus click to quantity + 1 , minus click to quantity - 1).

You are returning a same ID for each row. try this:
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
In my app there is a Edit text and below there is a list with check box.When user selects a particular checkbox,that value is being displayed in the edittext.Now if user writes some values in the edittext and then selects the checkbox,then the value which user had typed is overridden by the selected value.I want both the values to be displayed in the edittext

This will display what is currently in the EditText and the new text separated by a comma. Change

to
String s = holder.tvContact.gettext().toString();
holder.setText(s + ", " + data.get(i).getEmail());
I have an Vertical listview i want listview should be closed. For example if the last item is reached in Listview then show the first item below the last item. It means item should be in circular format. And if i scroll from first item it should show last item before first item. I want scrolling for both side.

i am trying to filter the listview using edit text at the top but it providing null pointer exception in the adapter2.filter(text) of add text changed listener . please provide me some suggestion`
Here is my edit text`
friendsList.setAdapter(new FriendListAdapter(this));
search.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
String text = search.getText().toString().toLowerCase(Locale.getDefault());

adapter2.filter(text);
}
#Override

i am passing the facebook friend list to the listview.please provide some suggestion
Thanks in advance
For filter the listview using edit text at the top .
I used this code.
Make one list called searchResults than in onTextChanged method of edittext simply do this-
String searchString = `your edittext object`.getText().toString();
int textLength = searchString.length();
searchResults.clear();
for (int i = 0; i < `your main list of items`.size(); i++) {
String name = `your main list of items`.get(i).get("`your key`").toString();
System.out.println(" name " + name);
if (textLength <= title.length()) {
// compare the String in EditText with Names in the
// ArrayList
if (searchString.equalsIgnoreCase(name.substring(0, textLength))) {
searchResults.add(`your main list of items`.get(i));
System.out.println("the array list is "+ `your main list of items`.get(i));
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
}
}
if (searchResults.isEmpty()) {
Toast toast = Toast.makeText(getApplicationContext(),"No Items Matched",Toast.LENGTH_SHORT);
toast.show();
mAdapter = new Adapter(this, searchResults);
`your ListView object`.setAdapter(mAdapter);
}
mAdapter.notifyDataSetChanged();
and on setOnItemClickListener just check searchResults.isEmpty() if true than use your your main list of items and if false than use searchResults list.
May be it will help you.try this.
change your filter with following code:
#Override
public Filter getFilter() {
//Log.d("in filter", "yes");
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
final FilterResults oReturn = new FilterResults();
and set your list in this function and after set your list :
oReturn.values = YourList;
and finall
return oReturn;
and in Your search.addTextChangedListener(new TextWatcher()) just in onTextChanged add following line:
adapter2.getFilter().filter(s.toString());
Try this,
adapter2=new FriendListAdapter(this);
friendsList.setAdapter(adapter2);
