Custom listview adapter with a chronometer refreshes when scrolled

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
public class RunnerLaps extends AppCompatActivity {

private Map<Runner,String> map = new HashMap<Runner,String>(10);
private boolean isClicked = true;

//Button b;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_runner_laps);
Intent i = getIntent();
serializableManager = new SerializableManager();
runner_array = (ArrayList<String>) getIntent().getSerializableExtra("KEY");
ArrayList<Runner> running = getIntent().getExtras().getParcelableArrayList("arr2");
runners_arrList = new ArrayList<Runner>(runner_array.size());
for (String r : runner_array)
{
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
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
CustomChrono chr = (CustomChrono) view.findViewById(R.id.chronometer_laps);
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);
i.putParcelableArrayListExtra("arr",arr_runners);
for (int h = 0; h < runners_arrList.size();h++)
{
System.out.println(runners_arrList.get(h).getName() + "\n");
System.out.println(runners_arrList.get(h).laps[0] + "\n");
System.out.println(runners_arrList.get(h).laps[1] + "\n");
System.out.println(runners_arrList.get(h).laps[2] + "\n");
}
startActivity(i);
}
else
{
r.laps[r.counter] = chr.getText().toString();
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");
System.out.println(runners_arrList.get(h).laps[1] + "\n");
System.out.println(runners_arrList.get(h).laps[2] + "\n");
}
}
}
else
{}
}
});
}
}

I would use Action Mode with MultiChoiceModeListener.
http://developer.android.com/reference/android/widget/AbsListView.MultiChoiceModeListener.html
There is a callback onItemCheckedStateChanged(ActionMode mode, int position, boolean checked).
You can easily get values of already checked list items ListView.getCheckedItemPositions. So you can prevent selection, if you already selected two or even at once pass the values(or ids) of selected ones without any effort.

You can simply put a counter on item selection.
Take a variable say for ex.
int count = 0;
Check this variable before marking item as selected/deselected:
if(item.isSelected())
{
// you need to make is disable
if(count>0)
{
count--;
// // mark item as deselected
}
}
else
{
// make it selected
if(count<2)
{
count++;
// mark item as selected
}
}
This will make you select ONLY TWO items at a time.
Modify your adapter like this:
public class LoadAdapter extends BaseAdapter {
private ArrayList<DataBase> mProductItems;
private LayoutInflater mLayoutInflater;
private Context mContext;
DBHelper mydb;
DataBase stringItem;
ArrayList<Boolean> selected = new ArrayList<>();
private int count=0;
public LoadAdapter(Context context, ArrayList<DataBase> arrayList){
mContext = context;
mProductItems = arrayList;
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
for (int i = 0; i < arrayList.size(); i++) {
selected.add(false);
}
}
#Override
public int getCount() {
// TODO Auto-generated method stub
Log.e("testtt", String.valueOf(mProductItems.size()));
return mProductItems.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mLayoutInflater.inflate(R.layout.load_chart_item, parent, false);
holder.txtv_name = (TextView) convertView.findViewById(R.id.text);
holder.nameid = (TextView) convertView.findViewById(R.id.nameid);
holder.btn_delete = (Button) convertView.findViewById(R.id.btn_delete);
holder.btn_edit = (Button)convertView.findViewById(R.id.btn_edit);
holder.location = (TextView)convertView.findViewById(R.id.loc);
holder.btn_delete.setTag(position);
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
mydb = new DBHelper(mContext);
stringItem = mProductItems.get(position);
if (stringItem != null) {
if (holder.txtv_name != null) {
holder.txtv_name.setText(stringItem.getName());
holder.nameid.setText(stringItem.getId());
holder.location.setText(stringItem.getLocation());
Log.e("saved Location values",stringItem.getLocation());
}
}
if(selected.get(position))
{
//for selected row
holder.txtv_name.setTextColor(color.red);
}
else
{
// for not selected row
holder.txtv_name.setTextColor(color.black);
}
holder.txtv_name.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(holder.txtv_name.getCurrentTextColor()== R.color.black)
{
//is not selected
if(count<2)
{
count++;
selected.set(position,true);
// mark item as selected
}
}
else
{
//is selected
if(count>0)
{
count--;
selected.set(position,false);
// // mark item as deselected
}
}
notifyDataSetChanged();
}
});
holder.btn_delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
DataBase test = mProductItems.get(position);
String id = test.getId();
mydb.deleteContact(Integer.valueOf(id));
mProductItems.remove(mProductItems.get(position));
LoadAdapter.this.notifyDataSetChanged();
if (mProductItems.size() == 0){
mProductItems.clear();
LoadAdapter.this.notifyDataSetChanged();
}
}
});
Log.e("DataBase", String.valueOf(mydb.getAllCotacts()));
holder.btn_edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(mContext,UpdateData.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
SharedPreferences preff = PreferenceManager.getDefaultSharedPreferences(mContext);
SharedPreferences.Editor edi = preff.edit();
edi.putString("key",String.valueOf(position+1));
edi.apply();
mContext.startActivity(intent);
}
});
return convertView;
}
public void refresh(ArrayList<DataBase> items)
{
this.mProductItems = items;
notifyDataSetChanged();
}
private static class ViewHolder {
TextView txtv_name,nameid,location;
Button btn_delete,btn_edit;
}}
EDIT 2: For getting selected items from adapter define below method in
adapter and call it with an adapter object like : adp.getSelected()
public String getSelected() {
String selectedString = "";
int num=0;
for (int i = 0; i < selected.size(); i++) {
if (selected.get(i)) {
num++;
if (num == 1) {
selectedString = mProductItems.get(i).getName();
} else {
selectedString += "," + mProductItems.get(i).getName();
}
}
}
return selectedString;
}
Answer to issue 2 : If you want to use ImageView instead of text color change. The do the same things as above but replace the TextView + Color with ImageView + Image.
EDIT 3:
You have called the getSelected() method from a Null object. Modify your code like this:
listView = (SwipeListView) findViewById(R.id.listview);
loadAdapter = new LoadAdapter(getApplicationContext(),array_list);
listView.setAdapter(loadAdapter);
det.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String str = "";
str = loadAdapter.getSelected();
Toast.makeText(RelationShipChartList.this, str, Toast.LENGTH_SHORT).show();
}

How to start animation in custom listview

I want, when I click imageview in this, start animation(rotate).
My problem is: When scrolling, animation stopped.

return position;
}
public static class ViewHolder {
public CircularImageView ivFoodImage;
public ImageView ivLoad;
public TextView txtFoodName;
public TextView txtFoodDescription;
public TextView txtFoodTime;
}
}

Try this:
In your adapter constructor change these lines:
....
loadAnimation = new boolean[foodNameList.length];
for (int i=0; i < loadAnimation.length; i++) {
loadAnimation[i] = false;
}
....
In getView() method add this:
...
viewHolder.ivLoad.setImageResource(R.drawable.load);
if(loadAnimation[position]){
viewHolder.ivLoad.setAnimation(anim);
viewHolder.ivLoad.startAnimation(anim);
} else {
viewHolder.ivLoad.setAnimation(null);
}
viewHolder.ivLoad.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHolder.ivLoad.setAnimation(anim);
viewHolder.ivLoad.startAnimation(anim);
loadAnimation[position] = true;
}
});
...
Hope it helps!

in your adapter getView() method set the status of the clicked checkbox in model and call notify data set changed, try that

I added the following lines with my code and it started working fine:
ArrayList<Integer> checkedPositions = new ArrayList<Integer>();
final Integer index = new Integer(position);
holder1.chckbx1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (((CheckBox) v).isChecked()) {
// if checked, we add it to the list
checkedPositions.add(index);
} else if (checkedPositions.contains(index)) {
// else if remove it from the list (if it is present)
checkedPositions.remove(index);
}
}
});
// set the state of the checbox based on if it is checked or not.
holder1.chckbx1.setChecked(checkedPositions.contains(index));

Custom ListView with Scrolling

I am facing a problem in custom listview where i am having 10 rows of values displayed inside the textview from db.
When i scroll the list the items are duplicated.
Consider that i have number of rows named from 1 to 10.
if i scroll it, the rows are duplicated as 1,2,3,4,5,1,6,7,8,9,2,3,etc.. the same values are again displayed. I don't know why this occurs. If i remove 5 items and disable scrolling, then it does not have any sort of issues.
Adding more number of rows with scrolling enabled arises this issue.
