Getting focus of EditText inside RecyclerView

I'm implementing an application in which user can store Debit Cards and later they can use it by just entering the CVV number of the same card. I have used RecyclerView for all the items(Debit Cards) stored by the user. Everything is working fine, view is rendering all good and I have used LinearLayoutManager to show Horizontal scroll.
Now the problem which I am facing is whenever I try to enter CVV of any card as soon as I click on it the view gets shifted towards the last item of the list of Stored Cards, So if I'm having three cards stored in my list and I try to enter CVV for the first one the view is shifting directly to the third card but the focus remains on the first cards EditText. I don't know what's going on with the same. I'm sharing some code part for the same.
Setting adapter and defining horizontal scroll :-
recyclerAdapter = new RecyclerStoredCardAdapter(mContext, storedCards);
LinearLayoutManager layoutManager
= new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
storedCardListRecycler.setLayoutManager(layoutManager);
storedCardListRecycler.setVisibility(View.VISIBLE);
storedCardListRecycler.setAdapter(recyclerAdapter);
Sharing the screenshots with this so it will get clear. Any help would be appreciable. Thanks.

I have did this using ListView not with RecyclerView
But you can do with RecyclerView also.

I am giving you my whole class. why? Because it will give you more understanding that how I used it with ListView.
Test it and Let me know. :)
Note
This line of code is very important - getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);

Not able to reproduce this issue. Let me know if the following code does what you are facing. If not, can provide more feedback if you share you Adapter's Code.
MainActivity.java
public class MainActivity
extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
MyAdapter adapter = new MyAdapter();
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
recyclerView.setAdapter(adapter);
}
}
public class MyAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_ite, parent);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
((EditText)((MyViewHolder)holder).mBinding.findViewById(R.id.editText)).setHint(position + " ");
}
#Override
public int getItemCount() {
return 100;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
View mBinding;
public MyViewHolder(View binding) {
super(binding);
this.mBinding = binding;
}
}
}
The 2xml layouts:
<EditText
android:id="#+id/editText"
android:layout_height="200dp"
android:layout_width="300dp"/>
</android.support.v7.widget.CardView>
My main_activity.xml is as follows:
<RelativeLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
</RelativeLayout>
As you can see this is the simplest case. Let me know if I missed anything.

How to increment TextView value outside ListView when ListView button is clicked in Android

I have a TextView outside ListView and i need to add prices when the plus button (ie,quantity is incremented )in ListView is clicked.In my program i am not able to add prices when new position ListView button is clicked.I need to find the total price to be payed by the customer when plus button is clicked in ListView
public class ListAdapter1 extends BaseAdapter {
public int qty=1;
public ArrayList<Integer> quantity = new ArrayList<Integer>();
private TextView total;
private String[] listViewItems,prices,weight;
TypedArray images;
public static int pValue;
private Context context;
public static boolean t=false;
CustomButtonListener customButtonListener;
public void setTextView(TextView total)
{
this.total = total;
}
public ListAdapter1(Context context, String[] listViewItems, TypedArray images, String[] weight, String[] prices) {
this.context = context;
this.listViewItems = listViewItems;
this.images = images;
this.prices=prices;
this.weight=weight;
}
public void setCustomButtonListener(CustomButtonListener customButtonListner)
{
this.customButtonListener = customButtonListner;
}
#Override
public int getCount() {
return 5;
}
#Override
public String getItem(int position) {
return listViewItems[position];
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView, final ViewGroup parent) {

final ListViewHolder listViewHolder;
if(convertView == null)
{

listViewHolder.edTextQuantity = (EditText) row.findViewById(R.id.editTextQuantity);
listViewHolder.btnMinus = (ImageButton) row.findViewById(R.id.ib_remove);
row.setTag(listViewHolder);
}
else
{
row=convertView;
listViewHolder= (ListViewHolder) row.getTag();
}
try{
listViewHolder.edTextQuantity.setText(quantity.get(position) );
}catch(Exception e){
e.printStackTrace();
}
listViewHolder.btnMinus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, " " + position, Toast.LENGTH_SHORT).show();
int mValue = Integer.parseInt(listViewHolder.edTextQuantity.getText().toString());
if (mValue <=0) {
System.out.println("not valid");
mValue=0;
listViewHolder.edTextQuantity.setText("" +mValue);
}
else{
pValue=pValue/mValue;
mValue--;
pValue=pValue*mValue;
total.setText(String.valueOf(pValue));
System.out.println("mvalue after reducing-----------"+mValue);
System.out.println("pvalue-----------"+pValue);
listViewHolder.edTextQuantity.setText( "" +mValue );
}
}
});
listViewHolder.btnPlus.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, " " + position, Toast.LENGTH_SHORT).show();
int mValue = Integer.parseInt(listViewHolder.edTextQuantity.getText().toString());
pValue=Integer.parseInt(listViewHolder.tvPrices.getText().toString());
mValue++;
listViewHolder.edTextQuantity.setText("" + mValue);
System.out.println("mValue after increment---" + mValue);
pValue=pValue*mValue;
System.out.println("pvalue-----------"+pValue);
total.setText(String.valueOf(pValue));
}
});
return row;
}
I need to get total price when any of the ListView button is clicked.

First you need to store value in HashMap<> when user click the plus and minus button.
Then sum the all values in HashMap.
For Example
try{
int sum = 0;
for(HashMap<String, String> map : arrayList) {
sum += Integer.parseInt(map.get("mark"));
}
} catch (Exception e) {
//Manage your exception
}
// sum has the value for the marks total.
System.out.println("Total Marks: "+sum);
Refere my previous answer Here

For that you need to create interface which notify in activity where you want that count.
put snippet in adapter to initialize interface and setter.
public interface IEvent {
void onItemChange(int count);
}
private IEvent iEvent;
//setter method for interface
public void setQuanityEvent(IEvent ievent) {
this.lastPageHandler = handler;
}
put this code in btnMinus.setOnClickListener
//if ievent interface variable register via set
if (ievent != null) {
//pValue is quality COUNT you want to send outside listview.
ievent.onItemChange(pValue);
}
activity code after creating adapter instance
//ListAdapter1 adapter = new ListAdapter1(your params);
adapter.setQuanityEvent(new ListAdapter1.IEvent() {
#Override
public void onItemChange(int count) {
}
}
});

Multiple Countdown Timer in Expandable Listview Android not working

From last week I am trying to implement multiple countdown timer in expandable list view.I want to decrease time till 00:00:00 and according to that I need to update text in parent element of expandable list view.
My problem is :
1) on scrolling expandable list view timer restarts
2) on expand and collapse timer restarts
3) on event on child button i need to update particular position's text on parentview
One more thing I'm trying to implement is on clicking one button from child view I need to update text on parent view but i'm stucked there.
Here is my adapter containing both parent and child.

Please help me out I'm stucked here still I am trying to work on it but I have time constaint.
Thanks!

I got to say this first, your code is really hard to read.
Try to split using methods the view creation code from your busyness code on getGroupView and getChildView. Also you could use ViewHolder pattern on getChildView to hold your views instead of thoses arrays (ll_whoaccpted, etc...)
TextUtils.isEmpty() can help you check better is your String are empty or null
if (TextUtils.isEmpty(headerTitle.getRemaining_completion_time()))
//instead of
if (headerTitle.getRemaining_completion_time().equalsIgnoreCase("") || headerTitle.getRemaining_completion_time() == null)
Make Sent_ListAdapter implement OnClickListener instead of recreating the listener (new) each time Android gets a View for your list. Add a condition on the view parameter to check which view type was click.
Work with Date and SimpleDataFormat on CountDownTimer, thoses manual string formatting are just awfull and unreadable
Well now to the main subject :
on scrolling expandable list view timer restarts
This happends because a ListView recreates the views/groups that are not showned (calling the getView/getGroup methods) to reuse the rows for other data.
If you want to avoid this you should create and start your counters outside the getView and getGroup (the constructor is a good place).
on expand and collapse timer restarts
Exactly the same thing that happends on the first problem.
on event on child button i need to update particular position's text
on parentview
I didn't really get this so am guessing that you want to change the text of a TextView on the main layout (the one containing the listview). Well you need to give a reference of that TextView to the Sent_ListAdapter.
Or, instead of passing a generic Context to the Sent_ListAdapter pass the Activity/Fragment it self :
public Sent_ListAdapter(MyActivity activty, List<SentModel> listDataHeader, HashMap<SentModel, List<SentModel>> listChildData) {
this._myactivity = myactivity;
this._listDataHeader = listDataHeader;
...
}
// The listener that handles all the events of your Sent_ListAdapter
#Override
public void onClick(View v) {
if(v.getTag() == "theBoutonThatShouldResetTheCounter") { //or other condition
myactivite.myTextView.setText("------");
}
}
Edit
But how will I get position in constructor for every row?
You need to think the other way around : the listview uses your datasource to show the rows. So you need to loop over the elements on your datasource (listDataHeader in your case). Something like :
private List<CountDownTimer> counters;
public Sent_ListAdapter(Context context, List<SentModel> listDataHeader, HashMap<SentModel, List<SentModel>> listChildData) {
...
counters = new ArrayList()<>;
for(SentModel model : listDataHeader) {
long milliseco = model.getRemainingTimeInMs(); //TODO: create something like this or figure out how to get your couters starting times on ms
CountDownTimer cdt = new MyCountDownTimer(milliseco, 1000);
cdt.start(); // I don't know when you want to start your counters, if they start at the same time it could be here
}
}
public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
...
datetime_element = (TextView) convertView.findViewById(R.id.datetime_element);
deadline = (TextView) convertView.findViewById(R.id.deadline);
...
CountDownTimer cdt = counters.get(groupPosition);
cdt.setTv1 = datetime_element;
cdt.setTv2 = deadline;
...
}
public class MyCountDownTimer extends CountDownTimer {
public TextView tv1; //TODO: make setters instead of public
public TextView tv2; //TODO: make setters instead of public
public MyCountDownTimer(long millisInFuture, long countDownInterval) {
super(millisInFuture, countDownInterval);
}
#Override
public void onTick(long millisUntilFinished) {
//Only use this if u have something to do each tick
SimpleDateFormat df = new SimpleDateFormat(" dd,hh:mm:ss");
Date timeRemaining = //TODO: figure out how you calculate your remaining time
if(tv1 != null) {
tv1.setText(df.format(timeRemaining));
}
}
#Override
public void onFinish() {
if(tv1 != null && tv2!= null) {
tv1.setText("Completion time over");
tv2.setVisibility(View.GONE);
}
}
}

Refresh ListView pressing option DialogFragment

I have a listview that clicking on an element shows a DialogFragmen with several options, options that take the user will be shown in the item of listview TextView and I get the following error in execution:
Activity app.gepv.Inventario has leaked IntentReceiver com.immersion.android.haptics.HapticFeedbackManager$HapticFeedbackBroadcastReceiver#426e94b8 that was originally registered here. Are you missing a call to unregisterReceiver()?
Enter the code that I think is important, if you need anything else edit the question :)
This is mi DialogFragment:
final String[] items= equiDisp.toArray(new String[equiDisp.size()]);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Asigne equipo/equipos:")
.setOnKeyListener(new Dialog.OnKeyListener(){
public boolean onKey(DialogInterface arg0, int keyCode,KeyEvent event) {
// TODO Auto-generated method stub
if (keyCode == KeyEvent.KEYCODE_BACK)
{
finish();
//dialog.dismiss();
actualizarDisplay();
}
return true;
}
})
.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int item, boolean isChecked) {
Log.i("Dialogos", "Opción elegida: " + items[item]);
if(isChecked)
{
marcado.add(items[item]);
Log.i("Dialogos", "Marcado: " + items[item]);
obras.get(pulsado).equiA.add(Integer.parseInt(items[item]));
for( int k=0; k< obras.get(pulsado).equiA.size(); k++)
{
Log.i("Dialogos", "Equipos: " + obras.get(pulsado).equiA.get(k) );
}
}
}
});
So far everything is running well because I check with Log.i
This is the function ActualizarDisplay():

Buttons displaying download progress (from background thread) get mixed up when scrolling in Android

I have a bug that I think is due to the way that lists reuse objects. I have a list of download buttons that get a progress readout when downloading. The update code is in a background thread.
When I scroll the list, the buttons that are showing progress jump into other list elements. How can I stop this? It's difficult to visualize, so I made a video of it:
http://www.youtube.com/watch?v=EiT2YWb2Prs&feature=youtu.be
BTW, the video was made by my client, so disregard the "samsung bug" bit. I'm the developer...
Here is the code:

Your Download Thread keeps a reference to the Button. The Buttons get reused though for different list elements when you scroll. You need to find a way to update the Button in the Thread somehow. The Button in the Thread can also be null, when the list element is not visible.
Edit:
It's really not that complicated. First of all: you should use a ViewHolder, that's gonna make your life much easier. Then you could do something like that
#Override
public View getView(final int position, View convertView, ViewGroup view_group) {
View view = null;
ViewHolder holder = null;
if(convertView == null){
view = {inflate view}
view.setTag(holder = new ViewHolder());
holder.view1 = view.findViewById(...);
{get rest of the views}
}else{
view = convertView;
holder = (ViewHolder)view.getTag();
}
if(holder.getDownloadThread() != null){
holder.getDownloadThread().setButton(null);
}
...
}
You get the idea.
