Develop Reference

Open/Close SQL Database on the same thread

I'm developing a recipe book and I'm implementing this method to insert my Recipe in the Database. In the for cycle I get the ingredient's name and quantity from multiples EditText, saving each of them in an Ingredient.class instance (newIngredient). Then I insert the instance into the DB and add it to an ArrayList. The followings "if conditions" are for the title, time and other Recipe's attributes. Finally, I also insert Recipe and Tag instances in the relatives DB's tables and I close DB.
public void saveRecipe() {
dbHelper = new DatabaseHelper(context);
// creating new recipe from user input
Ingredient newIngredient;
String title, childIngredient, instruction, tag;
int target, time, childQuantity, calories;
int countIngredients = parentIngredientLayout.getChildCount();
int countTags = chipGroup.getChildCount();
ArrayList<Ingredient> ingredients = null;
ArrayList<Tag> tags = null;
View childViewIng = null;
EditText childTextViewI = null;
EditText childTextViewQ = null;
// ingredients fields settings
for (int d=0; d<countIngredients; d++) {
childViewIng = parentIngredientLayout.getChildAt(d);
childTextViewI = childViewIng.findViewById(R.id.ingredientsField);
childTextViewQ = childViewIng.findViewById(R.id.quantityField);
childIngredient = childTextViewI.getText().toString();
childQuantity = Integer.parseInt(childTextViewQ.getText().toString());
newIngredient = new Ingredient(childIngredient, childQuantity);
dbHelper.insertIngredient(newIngredient);
ingredients.add(newIngredient);
}
//recipe fields settings
if (photoPath1 == null)
photoPath1 = "";
if (photoPath2 == null)
photoPath2 = "";
if (photoPath3 == null)
photoPath3 = "";
if (titleText.getText().toString().isEmpty()) {
title = "";
} else {
title = titleText.getText().toString();
}
if (targetNumber.getText().toString().isEmpty()) {
target = 0;
} else {
target = Integer.parseInt(targetNumber.getText().toString());
}
if (timeNumber.getText().toString().isEmpty()) {
time = 0;
} else {
time = Integer.parseInt(timeNumber.getText().toString());
}
if (instructionText.getText().toString().isEmpty()) {
instruction = "";
} else {
instruction = instructionText.getText().toString();
}
if (caloriesNumber.getText().toString().isEmpty()) {
calories = 0;
} else {
calories = Integer.parseInt(caloriesNumber.getText().toString());
}
if (tagName.getText().toString().isEmpty()) {
tag = "";
} else {
tag = tagName.getText().toString();
}
Recipe newRecipe = new Recipe(title, photoPath1, photoPath2, photoPath3, instruction, target, time, calories, ingredients);
Tag newTag = new Tag(tag);
dbHelper.insertRecipe(newRecipe);
dbHelper.insertTag(newTag);
dbHelper.close(); }
I found out by debugging that in this case is inserted only the first ingredient. I tried to move the FOR until the end of code, but in that case, are inserted both recipe and tag and always only the first ingredient. I think the problem is relative to the opening/closing of the DB. Can somebody help me?
Ingredient constructor:
public Ingredient(String ingredient_name, int quantity) {
this.ingredient_name = ingredient_name;
this.quantity = quantity;
}
dbHelper.insertIngredient(newIngredient) method:
public boolean insertIngredient(Ingredient ingredient) {
db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put(INGREDIENT_NAME, ingredient.getIngredient_name());
contentValues.put(QUANTITY, ingredient.getQuantity());
contentValues.put(KEY_CREATED_AT, time.getTime().toString());
long result = db.insert(TBL_INGREDIENTS, null, contentValues);
//db.close();
Log.e(TAG, "Ingredient inserted!");
if (result == -1) {
return false;
} else {
return true;
}
}

Ok, thanks to your comment we got the problem :)
You are calling .add(newIngredient) on a list that you initialized with ArrayList<Ingredient> ingredients = null;
Change it to
ArrayList<Ingredient> ingredients = new ArrayList<Ingredient>();
and it will work :)
Good luck!

Parcelable object with enums in Android

In an android project i have a class with these fields:
public class TransactionHistoryDetail1 implements Parcelable, DatabaseEnabled{
private long id;
private static final String TABLE_NAME = "TransactionHistoryDetail";
private static final String EMPTY_STRING = "";
#XmlElement(name = "TxUd", required = true)
private String TxUd;
#XmlElement(name = "TxLclDtTm", required = true)
private Date TxLclDtTm;
#XmlElement(name = "CcyCd")
private CurrencyCode CcyCd;
#XmlElement(name = "Amt")
private BigDecimal Amt;
#XmlElement(name = "PmttpCd", required = true)
private PaymentTypeCode PmttpCd;
#XmlElement(name = "OprtnCd", required = true)
private OperationCode OprtnCd;
#XmlElement(name = "AppLabltpCd", required = true)
private AppLabelTypeCode AppLabltpCd;
#XmlElement(name = "PdSrl")
private String PdSrl;
#XmlElement(name = "PdBrndDsc")
private String PdBrndDsc;
#XmlElement(name = "UsrEml")
private String UsrEml;
#XmlElement(name = "CstmrAdr")
private String CstmrAdr;
#XmlElement(name = "TxDtlDsc")
private String TxDtlDsc;
#XmlElement(name = "TxRltdInd")
private boolean TxRltdInd;
#XmlElement(name = "TxSttsCd", required = true)
private TransactionStatusCode TxSttsCd;
#XmlElement(name = "UpdtDt", required = true)
private Date UpdtDt;
...
}
Im trying to Write and Read objects of this class as Parcelables but im not sure how to write and read the enums.
My writeToParcel method looks like this:
#Override
public void writeToParcel(Parcel dest, int flags) {
SimpleDateFormat sdf = new SimpleDateFormat(JsonBuilder.DateFormat);
dest.writeLong(id);
dest.writeDouble(Amt.doubleValue());
dest.writeString(PdSrl);
dest.writeString(PdBrndDsc);
dest.writeString(TxUd);
dest.writeString(PdSrl);
dest.writeString(UsrEml);
dest.writeString(CstmrAdr);
dest.writeString(TxDtlDsc);
dest.writeString((CcyCd == null) ? "" : CcyCd.name());
dest.writeString((PmttpCd == null) ? "" : PmttpCd.name());
dest.writeString((OprtnCd == null) ? "" : OprtnCd.name());
dest.writeString((AppLabltpCd == null) ? "" : AppLabltpCd.name());
dest.writeString(sdf.format(TxLclDtTm));
dest.writeString(sdf.format(UpdtDt));
dest.writeByte((byte) (TxRltdInd ? 1 : 0));
}
and my Constructor with Parcel looks like this
private TransactionHistoryDetail1(Parcel in) {
SimpleDateFormat sdf = new SimpleDateFormat(JsonBuilder.DateFormat);
try {
TxLclDtTm = sdf.parse(in.readString());
UpdtDt = sdf.parse(in.readString());
} catch (ParseException e) {
e.printStackTrace();
}
id = in.readLong();
TxUd = in.readString();
PdSrl = in.readString();
PdBrndDsc = in.readString();
UsrEml = in.readString();
CstmrAdr = in.readString();
TxDtlDsc = in.readString();
TxRltdInd = in.readByte() != 0;
Amt = new BigDecimal(in.readDouble());
CcyCd = CurrencyCode.valueOf(in.readString());
PmttpCd = PaymentTypeCode.valueOf(in.readString());
OprtnCd = OperationCode.valueOf(in.readString());
AppLabltpCd = AppLabelTypeCode.valueOf(in.readString());
TxSttsCd = TransactionStatusCode.fromValue(in.readString());
}
The writeToParcel i belive its working well, but the constructor is crashing at the "CcyCd" line.
My CurrencyCode class is a enum, (so are PaymentTypeCode,OperationCode and AppLabelTypeCode) that looks like this:
#XmlType(name = "CurrencyCode")
#XmlEnum
public enum CurrencyCode {
EUR;
public String value() {
return name();
}
public static CurrencyCode fromValue(String v) {
return valueOf(v);
}
}
Is there another way to deal with enums in Parcelables?
The exception i get is this:
java.lang.RuntimeException: Unable to start activity ComponentInfo{package/package.activities.ChildActivity}: java.lang.IllegalArgumentException: No enum constant package.data.apiClasses.CurrencyCode.��EUR����CASH������CLS����APP����2017-04-10T09:07:52.525Z������2017-04-10T09:07:52.528Z����������CHILD_12345������?

First of all you should read from the Parcel in the exact order that you wrote to it. Since Parcel just write and read data in order instead of actually serializing data you have to keep read and write in order else you gonna read wrong values and getting error..
It is the best if you treat Enum as int, write them to parcel like this:
dest.writeInt(this.CcyCd == null ? -1 : this.CurrencyCode.ordinal());
and read them like this:
int tmpCurrencyCode = in.readInt();
this.CcyCd = tmpCurrencyCode == -1 ? null : CurrencyCode.values()[tmpMState];
P.S: This code check for null values too ^^

I had problem parsing Nullable Enum. If this is your case, look up here

Insert new data in Custom Adapter and update list

I have an list with an custom adapter, and upon refresh I want to add new data to be displayed(if any available).
But the list isn't being update. I tried all the methods with notifyDataSetChanged for the adapter but it's not updated.
Please help. I lost so much time with this and I feel like I'm loosing my mind with this one.
Here is the code:

The adapter on the list is set after the first request, when I get my first results, like this:

// Sort the list before displaying
Collections.sort(FeedItemParser.FEEDS, Comparators.CREATED_TIME);
// Set the custom adapter
customAddapter = new NewsFeedArrayAdapter(activity);
// Populate the fragment with the data from JSON
actualListView.setAdapter(customAddapter);
FeedItemParser is an custom class where I store my custom objects:

#Override
public String toString() {
return feed_story_message;
}
}
}
When I request new data(refresh), I add the new data in my object (the same way I do the first time):
FeedItemParser.addItem(new FeedItem(
id,
from_id,
from_category,
from_name,
message,
null, // Will be gotten through another request
null,
privacy_value,
type,
status_type,
created_time,
updated_time,
likes,
comments));
After that I call
ListView actualListView = mPullRefreshListView.getRefreshableView();
// Need to use the Actual ListView when registering for Context Menu
registerForContextMenu(actualListView);
// Sort the list before displaying
Collections.sort(FeedItemParser.FEEDS, Comparators.CREATED_TIME);
// Notify list adapter to update the list
customAddapter.notifyDataSetChanged();
SOLUTION
Based on the recommendations of #Selvin I have managed to update my list after adding more data. Basically I changed my adapter(I'm not using an filtered list anymore, but I'm directly using my custom objects). And after I add new Object, I update the list by calling notifyDataSetChanged() on the existing adapter.
I have also update my code, maybe it will help someone else that is stuck is this situation.
Thanks again #Selvin.

Parsing json file with gson give error

I cant figure it out, please advise.
Thanks!

Your output seems odd. Is JSON result being coined by yourself?
Both response and Odd fields seem to start with ( ) instead of [ ] which denotes an array. On top of that, this do not even seems valid JSON at all.
In JSON one doesn't use =, but : and fields are separated by ; instead of ,. For example:
{
meta : {
message : OK,
"operation_message" : "<null>",
operationstatus : 0,
status : 200,
},
response : [{
GameResult : 3,
GameStatusType : 3,
ID : 106448,
Odds : [{
OddID : 84001,
Outcomes : [{
ID : 4,
Name : 1
}, {
ID : 5,
Name : X
}, {
ID : 6,
Name : 2
}],
Result : "<null>",
TypeID : 10,
TypeName : ThreeWay,
Value : "<null>"
}],
"T1_Result" : 0,
"T2_Result" : 0,
TotalBets : 76,
WinnerID : "<null>",
isEnded : 0
}, {
....

Json parsing with gson not working

This is my JSON string:
[{"BranchID":1,"SecurityCode1":13,"SecurityCode2":14,"PrintHeight":10,"PrintWidth":10,"Active":true}]
This is Code I am using to parse the JSON:
Type t = new TypeToken<List<Setting>>() {
}.getClass();
String json = ServiceHelper.getJSON(response);
List<Setting> list = (List<Setting>) gson.fromJson(json, t);
//list is null which it souldnt
This is the Setting class, Entity is ORMDroid entity class:
public class Setting extends Entity {
#Column(name = "id", primaryKey = true)
#SerializedName("BranchID")
public int BranchID;
public int securityCodeLPK;
public int securityCodeSDK;
#SerializedName("PrintHeight")
public int PrintHeight;
#SerializedName("PrintWidth")
public int PrintWidth;
#SerializedName("Active")
public String Active;
#SerializedName("SecurityCode1")
public String SecurityCode1;
#SerializedName("SecurityCode2")
public String SecurityCode2;
public Setting(int BranchID, int height, int width, String active, String securityCode1, String securityCode2) {
super();
BranchID = BranchID;
PrintHeight = height;
PrintWidth = width;
Active = active;
SecurityCode1 = securityCode1;
SecurityCode2 = securityCode2;
}
public Setting () {
super();
}
}
It seems to be OK, but list after gson.FromJson is null. What's wrong with this code?
Please help

You should use getType() instead of getClass().
Type t = new TypeToken<List<Setting>>() {}.getType();
