please help.i tryed many code from stack but not working
holder.setIsRecyclable(false);
setHasStableIds(true);
this is not working for me

In RecyclerView when scrolling state of view removed and creating new view by scroll,
you must change your data when radioButton or edittext content changed, and set new data in your model.

Android checkbox checked at random position in Listview

I know it is common problem with Listview and Checkbox, I am try from 2 days but it is not solving, so I raised question here.
I had list of items in Arraylist, like 15(supposed) items. Inside listview there is a checkbox, by default 11(supposed) checkbox is comes checked by API (JSON Response)
But I have to show only 5 items checked. I tried alot but not find any solution.
I had create a dummy list that contain 11 items that comes from API and save 5 items from original arraylist. Here is code to match items in listview and save this list in Shared Preference.
Adapter class inside getViwe() function
List<SaveOrderId> getIds = prefManager.getNewOrders(context);
for (int i = 0; i < getIds.size(); i++) {
String idget = getIds.get(i).getOrderId();// it get ids from save list
for (int j = 0; j < newOrders.size(); j++) {
String bot = newOrders.get(j).getId(); // id from orginal list
if (bot.equalsIgnoreCase(idget)) {
showErrorLog(TAG, String.format("Bot id is %s and Saved Id is %s", bot, idget));
myViewHolder.add_payment.setChecked(true);
final int sdk = android.os.Build.VERSION.SDK_INT;
if (sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
myViewHolder.txt_layout_checked.setBackgroundDrawable(ContextCompat.getDrawable(context, R.drawable.shape_rect_rounder_corner3_bg_green));
} else {
myViewHolder.txt_layout_checked.setBackground(ContextCompat.getDrawable(context, R.drawable.shape_rect_rounder_corner3_bg_green));
}
myViewHolder.txt_check_status.setText("ADDED");
} else {
getPerspective().showErrorLog(TAG, "Not Equal");
myViewHolder.add_payment.setChecked(false);

I have tried recyclerViewT1.setHasFixedSize(false); but nothing is changing. The thing I noticed is that the data set is changing successfully but recyclerview is not showing new items.
when i try:
homeAdapter = new HomeAdapter(mNewsFeeds, mNewsFeeds.size() + 1, HOME_ADAPTER);
recyclerViewT1.setAdapter(homeAdapter);
instead of:
homeAdapter.notifyDataSetChanged();
it shows correct number of items but then user is pushed back to top and user needs to scroll again, which I don't want. I just want to update the data set with the new items.

update the getItemCount & your datas before set notifyDataSetChanged
In your adapter:
private int mListSize;
public void setItemCount(int listsize){
mListSize=listsize;
}
#Override
public int getItemCount() {
return mListSize;
}
before notifydataset changed:
if (recyclerViewT1.getAdapter() == null) {
homeAdapter = new HomeAdapter(mNewsFeeds, mNewsFeeds.size() + 1, HOME_ADAPTER);
recyclerViewT1.setAdapter(homeAdapter);
}else{
homeAdapter.setData(mNewsFeeds, mNewsFeeds.size() + 1, HOME_ADAPTER);
homeAdapter.setItemCount(yourlist.size());
homeAdapter.notifyDataSetChanged();
}
Try this answer also
https://stackoverflow.com/a/40220412/3879847

You should always provide new mNewsFeeds to HomeAdapter and call homeAdapter.notifyDataSetChanged(); to change data
try {
JSONArray arr = new JSONArray(trending);
for (int i = 0; i < arr.length(); i++) {
mNewsFeeds.add(postHelper(arr, i));
}
if (recyclerViewT1.getAdapter() == null) {
homeAdapter = new HomeAdapter(mNewsFeeds, mNewsFeeds.size() + 1, HOME_ADAPTER);
recyclerViewT1.setAdapter(homeAdapter);
}else {
homeAdapter.setNewsFeeds(mNewsFeeds)
}
homeAdapter.notifyDataSetChanged();
// getActivity().runOnUiThread(new Runnable() {
// public void run() {
// homeAdapter.notifyDataSetChanged();
// }
// });
// Log.e("coool", String.valueOf(mNewsFeeds.size()));

Thanks in Advance.

For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);

How to get position of view created dynamically in main Linear Layout?

I am creating here a dynamic layout. I have one parent layout in which I am adding all the dynamic created views. Now on click of particular view I need position.
According to that position I have to send JsonObject which contain this view in Android. Here I am not able to get exact position of view.
This is my code:
int len = result.length();
View addView;

finalResult.clear();

} catch (JSONException e) {
e.printStackTrace();
}
}
for (int i = 0; i < result.length(); i++) {
JSONObject obj = result.getJSONObject(i);
if (i == 0) {
addView = mInflater.inflate(R.layout.sightseeing_firstview, null);

textview = (TextView) addView.findViewById(R.id.textView1);
llfirst = (LinearLayout) addView.findViewById(R.id.llfirstview);
llayout.addView(addView);
String category1 = finalResult.get(i).getString("CategoryName");
imageurl1 = finalResult.get(i).getString("ImageUrl");
((BaseActivity) SightseeingToursActivity.this).imageLoader.displayImage(imageurl1, image,
Common.optionsSmall);
textview.setText(category1);
} else if (i % 5 == 0) {
addView = mInflater.inflate(R.layout.sightseeing_firstview, null);

type missmatch : cannot convert from string to int

public void clickresult(View v){
String temp = "";
int cards[] = {etnumber1.getText().toString(),etnumber2.getText().toString(),
etnumber3.getText().toString(),etnumber4.getText().toString()
,etnumber4.getText().toString()};

}
}
}
for (int i = 0; i < noOfCard; i++) {
temp += cards[i] + " ";
}
Toast.makeText(this, temp, Toast.LENGTH_LONG).show();
}
it still have one error -> type missmatch : cannot convert from string to int
how to fix that
int cards[] = {etnumber1.getText().toString(),etnumber2.getText().toString(),
etnumber3.getText().toString(),etnumber4.getText().toString()
,etnumber4.getText().toString()};

#Override
protected void onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.your_fragment_layout, container, false);
etnumber1 = (EditText)findViewById(R.id.etnumber1);
etnumber2 = (EditText)findViewById(R.id.etnumber2);
etnumber3 = (EditText)findViewById(R.id.etnumber3);
etnumber4 = (EditText)findViewById(R.id.etnumber4);
etnumber5 = (EditText)findViewById(R.id.etnumber5);
}
public void onClickResult(){
String cards[] = {etnumber1.getText().toString,
etnumber2.getText().toString(),
etnumber3.getText().toString(),
etnumber4.getText().toString(),
etnumber5.getText().toString()
};
int noOfCard = cards.length;
Arrays.sort(cards);
StringBuilder builder = new StringBuilder();
for (String s : cards)
builder.append(s).append(" ");
Toast.makeText(context, builder.toString(), Toast.LENGTH_SHORT).show();
}
This will sort your array and display it in a Toast in this format: "2 3 5 6 7" (according to the numbers you provided). If the EditTexts are going to have only numbers, consider using NumberPicker instead.
LENGTH_SHORT can also be LENGTH_LONG.

public class MainActivity extends Activity {
EditText number1,number2,number3,number4,number5;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
number1 = (EditText)findViewById(R.id.etnumber1);
number2 = (EditText)findViewById(R.id.etnumber2);
number3 = (EditText)findViewById(R.id.etnumber3);
number4 = (EditText)findViewById(R.id.etnumber4);
number5 = (EditText)findViewById(R.id.etnumber5);
}
public void clickresult(){
int cards[] = {6,7,3,2,5};
int noOfCard = cards.length;
for (int marker = 1; marker < noOfCard; marker++) {
for (int j = 0; j < marker; j++) {
if (cards[marker] < cards[j]) {
int tmp = cards[marker];
cards[marker] = cards[j];
cards[j] = tmp;
}
}
}
for (int i = 0; i < noOfCard; i++) {
System.out.print(cards[i] + " ");
}
System.out.println();
}
