how to prevent to creating the duplicate item while scrolling my recyclerview - android-adapter

Here is My AdapterClass AvailablePateientAdapter.java
plaese let me know the how to resolve this issue while scrolling my recyclerview each time increasing the duplicate items
Thanks in advance.

Basically when we are adding new item in the list it needs refresh it but while refreshing it you will see the duplicates of the existing items because of previous list was not empty the list had some items. So clear the list first before adding the items in the list.
add the following changes in ActivityPatient.java
private void availablePatData(List<PatientData> patData) {
int j = 0;
if(availablePatData.size()>=0){
availablePatData.clear();
}
Log.d(Config.LOG_TAG, "size" + patData.size());
for (int i = 0; i < patData.size(); i++) {
// Log.d(Config.LOG_TAG, "Patient id" + patData.get(i).getPatientId());
if (patData.get(i).getStatus().equalsIgnoreCase(getResources().getString(R.string.report_status_available)) ||
patData.get(i).getStatus().equalsIgnoreCase(getResources().getString(R.string.report_status_screening_done))) {
availablePatData.add(j,patData.get(i));
j++;
}
}

DynamoDB: Enum as partition key giving error "Missing the key id in the item" when putItem

I am using the enum as the partition key and my model looks like below
#DynamoDbBean
public class Item {
public enum Key {
KEY_A(false),
KEY_B(2),
private final Object defaultValue;
private Key(Object defaultValue) {
this.defaultValue = defaultValue;
}
public Object getDefaultValue() {
return this.defaultValue;
}
}
private Key key;
private Object value;
public Item() {
}
public Item(Key key) {
this.key = key;
this.value = key.getDefaultValue();
}
#DynamoDbConvertedBy(KeyEnumConverter.class)
#DynamoDbPartitionKey
public Key getKey() {
return key;
}
public void setKey(Key key) {
this.key = key;
}
#DynamoDbConvertedBy(ValueConverter.class)
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}
My Converter classes to convert between java object and DDB data type is as below:
public class KeyEnumConverter implements AttributeConverter<Item.Key> {
#Override
public AttributeValue transformFrom(Item.Key key) {
return EnhancedAttributeValue.fromString(key.toString()).toAttributeValue();
}
#Override
public Item.Key transformTo(AttributeValue attributeValue) {
return Item.Key.valueOf(attributeValue.s());
}
#Override
public EnhancedType<Item.Key> type() {
return EnhancedType.of(Item.Key.class);
}
#Override
public AttributeValueType attributeValueType() {
return AttributeValueType.S;
}
public class ValueConverter implements AttributeConverter<Object> {
#Override
public AttributeValue transformFrom(Object Value) {
return getEnhancedAttributeValue(Value).toAttributeValue();
}
#Override
public Object transformTo(AttributeValue attributeValue) {
return JsonConvertor.getObjectFromJsonString(attributeValue.s(), Object.class);
}
#Override
public EnhancedType<Object> type() {
return EnhancedType.of(Object.class);
}
#Override
public AttributeValueType attributeValueType() {
return AttributeValueType.S;
}
private EnhancedAttributeValue getEnhancedAttributeValue (Object value) {
if (Value instanceof Boolean) {
return EnhancedAttributeValue.fromBoolean((Boolean)Value);
} else if(value instanceof Number) {
return EnhancedAttributeValue.fromNumber(String.valueOf(value));
} else {
throw new IllegalArgumentException("Please add support for type " + value.getClass().getSimpleName());
}
}
}
When I am putting an item into the table:
public void saveItem (String itemKey) {
Table.putItem(new Item(Item.Key.valueOf(itemKey)));
}
I got the error:
One or more parameter values were invalid: Missing the key id in the item
The partitionKey is defined in the model, why the key id still missing

I want to get all property in child class and all from base class when i add it into List<>. I have class 'SellNumber.cs' which extends from class 'Entity.cs', so I want to use all properties of parent class to use with collection 'List'.

EclipseLink JPA #OneToMany List is not same in differernt request of same session in Jesery REST

I have two entities as People and Story. Now I post my story and check my stories, but returns different Story List occasionally. I mean, usr.stories.hashCode() is not same in differernt request from the exactly same user. The database table is always correct, so I am very confused. I checked out Hibernate reference for better details, but it didn't help at all.
Model class:
#MappedSuperclass
public class People{
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "id", unique = true, nullable = false)
public Integer id;
#OrderBy(value = "id DESC")
#OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "people")
public List<Story> stories = new LinkedList<Story>();
public People(){
}
}
#MappedSuperclass
public class Story{
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "id", unique = true, nullable = false)
public Integer id;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "people_id")
public People people;
#Column(name = "story", nullable = false)
public String story;
public Story(String story){
this.story = story;
}
}
REST class:
#Path("/story")
public class StoryRS {
#POST
public StreamingOutput create(final #Context HttpServletRequest req, final String story) throws IOException{
return new StreamingOutput() {
#Override
public void write(OutputStream os) {
HttpSession hs = req.getSession(false);
if (hs != null && story != null && story.trim().length() > 0) {
Integer uid = (Integer) hs.getAttribute("uid");
People usr = uid != null ? PeopleDAO.findById(uid) : null;
if (usr != null) {
Story obj = new Story(story);

Thanks a lot for any response

Here's your problem
public static EntityManager getEntityManager() {
EntityManager manager = threadLocal.get();
if (manager == null || !manager.isOpen()) {
manager = emf.createEntityManager();
threadLocal.set(manager);
}
return manager;
}
EntityManager's are supposed to be short-lived objects. They're cheap to make and cheap to destroy. It also explains why you are getting inconsistent results. EntityManagers have an internal cache which is surprisingly aggressive.
The rule for working with EM's is "One EntityManager per transaction."
Change your code to get a new EM every time and your problems will go away.

How to add different layouts for children in expandable list view in android?

I'm trying to implement expendable list view with two different layouts for children in different groups. After quite a bit of searching I came up with the following code for my adapter. When I run application and try to expand last group (of 4 groups) it crashes with
ArrayIndexOutOfBoundsException: length=2; index=2
no matter for which group I check the condition in getChildType:
public int getChildType (int groupPosition, int childPosition) {
Log.i(TAG, "getChildType("+groupPosition+","+childPosition+") called");
if (groupPosition == 3)
return 1;
else return 0;
}
Thanks for any help!
Code for adapter:
public class ExpListAdapter extends BaseExpandableListAdapter {
private String TAG = "ExpListAdapter";
private String arrGroupelements[];
private String arrChildelements[][][];
private Context myContext;
public ExpListAdapter(Context context, String[] groupElements, String[][][] childElements) {
myContext = context;
arrGroupelements = groupElements;
arrChildelements = childElements;
}
public Object getChild(int groupPosition, int childPosition) {
return arrChildelements[groupPosition][childPosition];
}
public int getChildType (int groupPosition, int childPosition) {
Log.i(TAG, "getChildType("+groupPosition+","+childPosition+") called");
if (groupPosition == 3)
return 1;
else return 0;
}
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
public View getChildView( int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int gp = groupPosition;
int cp = childPosition;
Log.d(TAG, "groupPosition: "+gp);
Log.d(TAG, "childPosition: "+cp);
Log.d(TAG, "isLastChild: "+isLastChild);
if (convertView == null) {
if (getChildType(groupPosition,childPosition)==0)
convertView = inflater.inflate(R.layout.child_row, null);
else
convertView = inflater.inflate(R.layout.child_row_slide_btn, null);
}
if (getChildType(groupPosition,childPosition)==0) {
TextView fieldInfo = (TextView) convertView.findViewById(R.id.fieldInfo);
fieldInfo.setText(arrChildelements[gp][cp][0]);
EditText editField = (EditText) convertView.findViewById(R.id.editField);
editField.setText(arrChildelements[gp][cp][1], null);
editField.addTextChangedListener( new TextWatcher() {
public void afterTextChanged(Editable s) {
// Log.i(TAG,"afterTextChanged called");
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
});
} else {
CheckBox cb = (CheckBox)convertView.findViewById(R.id.onOff);
cb.setText("konj");
}
return convertView;
}
public int getChildTypeCount (int groupPosition) {
if (groupPosition==3)
return 2;
else
return 1;
}
public int getChildrenCount(int groupPosition) {
return arrChildelements[groupPosition].length;
}
public Object getGroup(int groupPosition) {
return arrGroupelements[groupPosition];
}
public int getGroupCount() {
return arrGroupelements.length;
}
public long getGroupId(int groupPosition) {
return groupPosition;
}
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.group_row, null);
}
TextView groupTitle = (TextView) convertView.findViewById(R.id.groupTitle);
groupTitle.setText(arrGroupelements[groupPosition]);
return convertView;
}
public boolean hasStableIds() {
return true;
}
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}

Seems the logic for getChildTypeCount(int groupPosition) and getChildType(int groupPosition, int childPosition) is not matching.
When group position is not 3 the type is 1 but count is 1 (which means there are more than 1 type)
