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.
Here is my used class demo.

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 refresh the contents of a list view

I have made a list view that shows the contents in the database. But if I add data in the database via a different activity then the modified list view is visible only when I close and then start my app.
So how do I refresh my List view so that as soon as the data is entered, it is visible in the list.
I have heard of notifyDataSetChange() but don't know where to put it in my code.
Please help. The TimePickerPop class is the class that adds data to the database.
public class MainActivityFragment2 extends Fragment {

cr.moveToFirst();
String TimeH, TimeM, EtimeH, EtimeM;
do {
TimeH = Integer.toString(cr.getInt(1));
TimeM = Integer.toString(cr.getInt(2));
EtimeH = Integer.toString(cr.getInt(3));
EtimeM = Integer.toString(cr.getInt(4));
TDList.add((new TimeList(TimeH + " : " + TimeM, EtimeH + " : " + EtimeM)));
}while (cr.moveToNext());
}

db.putInfo(db, time_picker1.getCurrentHour(), time_picker1.getCurrentMinute(), time_picker2.getCurrentHour(), time_picker2.getCurrentMinute(), 0, 0);
finish();
}
});
}
}

in your adapter create :
public void notifyChange() {
notifyDataSetChanged();
}
and from your activity call :
adapter.notifyChange();

How to retain the listview and the child fragment state after updating the contents of listview?

I have a listView of items.Each item has two separate fragment inside it and gets visible when the item is clicked. Inside a fragment there is another ListView and a button. The button displays a dialog through which ListView inside the fragment gets populated.The problem is when the dialog closes,the parent listview gets refreshed and as a result fragment visibility is gone. I have to click the parent list view item again to see the fragment and its content. I want the Fragment view and its updated content remain viewed after the dialog is dismissed. So someone please help me in it.

The button displays a dialog through which ListView inside the fragment gets populated.
not exactly clear to me. Did you meant inside your dialog you have some action that reflects on the fragment lisview?
have to click the parent list view item again to see the fragment and its content. I want the Fragment view and its updated content remain viewed after the dialog is dismissed
What i understand here u are doing something inside child view fragment that reflects on parent view list item, you are expecting the parent item data to be updated in view and also keeping the view state here u meant to be opened the parent item as it was (when u are updating the something inside fragment or dialog whatever)
My primary answer is you keep somehow keep the position to a member reference of the activity class where you actually setting the parent list in parent item onClick callback.
keep this position and later what you have to is to call a method inside adapter to pass the position to set a perform clic on item view
you may get a hints from this link..

how to update listview contents between fragments through the main activity

I have three fragments, the second and the third one, have a listView in their respective layout.
initially, the listView of both "second and third Frament", is populated with the same items. i other words, initially the the listView of
the second fragment and the third one, contain the following where CB: is checkBox and IV: is ImageView and t is: textview, and SaveButton is a buton
t1........CB.......IV
t2........CB.......IV
t3........CB.......IV
t4........CB.......IV
t5........CB.......IV
t6........CB.......IV
SaveButton
what i am trying to do is, while i am in the second fragment and selected an item(s) from the listView "using the checkbox" and clicked "Save" button, then, that item i selected, should be deleted from the listView in the third Fragment.
to achieve this,in getview(), i checked if the the checkBox is checked from the the listView of the second fragment, and if it is checked, i add the checked items
to a list. as shown in getView():
Second Fragment:
private void setUpListView() {
// TODO Auto-generated method stub
this.topicsList = new ArrayList<String>();
for (int i = 0; i < this.topics.length; i++) {
this.topicsList.add(topics[i]);
}
this.adapter = new ListViewAdapter(getActivity(), this.topicsList, ECO_FRAG_ID);
this.listView.setAdapter(adapter);
}
Third Fragment:
private void setUpListView() {
// TODO Auto-generated method stub
this.topicsList = new ArrayList<String>();
for (int i = 0; i < this.topics.length; i++) {
this.topicsList.add(topics[i]);
}
this.adapter = new ListViewAdapter(getActivity(), this.topicsList, LOGGER_FRAG_ID);
this.listView.setAdapter(adapter);
}
BaseAdapter:
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if (convertView == null) {
LayoutInflater layoutinflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = layoutinflater.inflate(R.layout.list_items_layout, null);
}
if (this.checkedItemsList1 == null) {
this.checkedItemsList1 = new ArrayList<String>();
}
if (this.checkedItemsList2 == null) {
this.checkedItemsList2 = new ArrayList<String>();
}
final TextView tv = (TextView) convertView.findViewById(R.id.tvlist_topic);
final CheckBox cb = (CheckBox) convertView.findViewById(R.id.cbList_hook);
final ImageView iv = (ImageView) convertView.findViewById(R.id.ivList_delete);
tv.setText(this.topicsList.get(position));
if (cb.isChecked() && (this.id == 1) ) {
this.checkedItemsList1.add(this.topicsList.get(position));
this.setCheckedItemsList1(this.checkedItemsList1);
}
if (cb.isChecked() && (this.id == 2) ) {
this.checkedItemsList2.add(this.topicsList.get(position));
this.setCheckedItemsList2(this.checkedItemsList2);
}
iv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (cb.isChecked())
cb.setChecked(false);
topicsList.remove(position);
notifyDataSetChanged();
}
});
return convertView;
}
And i created an interface, which is initialised in onAttach() and called when i click the savebuton in the secondFragment as folows:
private OnClickListener btnSaveListener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getActivity(), "Save to SQLite", Toast.LENGTH_SHORT).show();
Log.d(TAG, "size: " + adapter.getCheckedItemsList1().size());
iCSC.onCheckedStateChanged(adapter.checkedItemsList1, ECO_FRAG_ID);
}
};
this inerface, the mainActivity implements it, and in the implemntation of the interface, i pass the list f the checked items from the second Fragment to the third
Fragment through a public method in the third fragmet that updates the list and then assign the list to the adapter, as follows:
#Override
public void onCheckedStateChanged(ArrayList<String> list, int id) {
// TODO Auto-generated method stub
switch (id) {
case 1:
((Logger_Settings_Frag) this.fragList.get(2)).updateTopicList(list);
break;
case 2:
break;
}
}
**updateTopicList in the third fragment**
public void updateTopicList(ArrayList<String> list) {
for (String str : list) {
this.topicsList.remove(str);
}
this.adapter = new ListViewAdapter(getActivity(), this.topicsList, LOGGER_FRAG_ID);
this.listView.setAdapter(adapter);
}
updateTopicList in the third fragment
public void updateTopicList(ArrayList<String> list) {
for (String str : list) {
this.topicsList.remove(str);
}
this.adapter = new ListViewAdapter(getActivity(), this.topicsList, LOGGER_FRAG_ID);
this.listView.setAdapter(adapter);
}
when i run that code, in the saveButton listener of the second fragment, the log.d message displays that the size of the list that should contain the items that was checked, is zero size?!
please have a look at the code and let me know what i am missing?

try this: Its a sample Project OneActivity with two Fragments:
public ArrayList myBeansList_frgnt1;
public ArrayList myBeansList_frgnt2;
by clicking the save button iterate the myBeansList_frgnt1 and checking the condition that any item is selected or not. if item is selected i am adding that item to myBeansList_frgnt2 .showing in fragment2.

Ok, I "think" I know what's going on here. You setup your ListView and add its TransactionAddDropAdapter, and then set the total amount of items.
this.addDropListView = (ListView) view.findViewById(R.id.transactions_pending_transactionsListView);
this.addDropAdapter = new TransactionAddDropAdapter(pendingTradesView);
this.addDropListView.setAdapter(this.addDropAdapter);
TextView getTotalCount = (TextView) view.findViewById(R.id.transactions_pending_TransactionsAddDropCount);
getTotalCount.setText(""+addDropListView.getCount());
However, at this point, you haven't called setAddDropList(List<TransactionAddDrop> addDropList) on addDropAdapter, so addDropList in getCount() is still an empty array, so getCount() == 0, which is why you are seeing 0 being displayed.
So, you need to find where you call addDropAdapter.setAddDropList() and then call getTotalCount.setText(""+addDropListView.getCount()); right after in order to update the total number of rows.
