Android update sqlite table - android
I have written Update table using dbAdapter.
public void loadDownloadData() {
SoapPrimitive responsePrimitiveData;
//Loop Table list
for (int i = 0; i < tablesName.size(); i++) {
try {
responsePrimitiveData = soapPrimitiveData(tablesName.get(i));
if (responsePrimitiveData != null) {
try {
String result = responsePrimitiveData.toString();
JSONObject jsonobject = new JSONObject(result);
JSONArray array = jsonobject.getJSONArray("Table1");
int max = array.length();
// Loop each table data
for (int j = 0; j < max; j++) {
JSONObject obj = array.getJSONObject(j);
JSONArray names = obj.names();
StringBuilder strFields = new StringBuilder();
StringBuilder strValues = new StringBuilder();
String[] strToFields = new String[names.length()];
String[] strToFieldsVal = new String[names.length()];
//getting the Json name, values in separate string array
for (int k = 0; k < names.length(); k++) {
String name = names.getString(k);
strToFields[k] = names.getString(k);
String strVal;
if(obj.getString(name)== null){
strVal="";
strToFieldsVal[k]="";
}else{
if(obj.getString(name).equals(" ")){
strVal="";
strToFieldsVal[k]="";
}else{
String tmp1 = obj.getString(name).replaceAll("\\s+", " ");
String tmp = tmp1.replaceAll("\\s+", " ");
strVal =tmp.replaceAll("\\s+", " ");
strToFieldsVal[k]=strVal;
}
}
strFields.append(name + ",");
strValues.append(strVal+",");
} //end of json for loop
strFields.deleteCharAt(strFields.length() - 1);
strValues.deleteCharAt(strValues.length() - 1);
if(getTableUpdateType(tablesName.get(i)).equals("1")){
String actualtable = getAndroidTablename(tablesName.get(i));
if(isTableRecords(tablesName.get(i))){
String[] strWhereField = getTablePrimaryKey(tablesName.get(i),strBusinessUnit);
String[] strWhereFieldVal = new String[strWhereField.length];
StringBuilder whereFields = new StringBuilder();
for (int a = 0; a < strWhereField.length; a++) {
strWhereFieldVal[a] = obj.getString(strWhereField[a]);
whereFields.append(strWhereField[a] + "= ? and ");
}
whereFields.delete(whereFields.length() - 4, whereFields.length());
updateTableRecords(actualtable, strToFields, strToFieldsVal,whereFields.toString() ,strWhereFieldVal);
}else{
insertTableRecords(actualtable, strToFields, strToFieldsVal);
}
}else if(getTableUpdateType(tablesName.get(i)).equals("2")){
}else if(getTableUpdateType(tablesName.get(i)).equals("3")){
}else{
}
}//end of each table data
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
}
}
and I called like update method:
public void updateTableRecords(String strTableName, String[] strToFields, String[] strValues,String strWhereField ,String[] strWhereFieldVal){
DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(DownlaodTableActivity.this);
dbAdapter.openDataBase();
ContentValues initialValues = new ContentValues();
for(int i=0 ;i<strToFields.length;i++){
initialValues.put(strToFields[i],strValues[i]);
}
long n = dbAdapter.updateRecordsInDB(strTableName, initialValues, strWhereField, strWhereFieldVal);
System.out.println( " -- n--- " + n);
Toast.makeText(DownlaodTableActivity.this, n+" rows updated", Toast.LENGTH_SHORT).show();
}
I want to generate update statement dynamic way. From These code I put Where part also.But I did not generate where clause.
see :
UPDATE strTableName SET ExecutiveCode=?, FreeIssuePrefix=?, DisPaySchedulePrefix=?, NextFreeIssueNo=?, NextReturnNo=?, UploadedType=?, DisNextFOCNo=?, DisNextFreeIssueNo=?
Please help me How to give the Where clase(Here I gave String & arguments as string array)
Thanks in advance...
try like this
dbAdapter.updateRecordsInDB(strTableName, initialValues,""+whereField+"='"+whereFieldValue+"'",null);
if your whereField field's type is number then don't use ''
If you have to compare with multiple values use
String where="";
for(int i=0;i<strWhereField.length();i++)
{
where=where+whereField[i]+"='"+strWhereFieldValue[i]+"'"
if(i<(strWhereField.length()-1)) where=where+" and"
}
dbAdapter.updateRecordsInDB(strTableName, initialValues,where,null);

How to get String Array from JSON Object
I am trying to get a list of available numbers from the following json object
void doJSONParser(String str)
{
try {
JSONObject order = new JSONObject(str);
JSONArray index = order.getJSONArray("webnautes");
for(int i = 0; i < index.length(); i++)
{
JSONObject tt = index.getJSONObject(i);
name += "name: " + tt.getString("name")+"\n";
phone = new String[tt.getString("phone").length()];
//phone += "phone: " + tt.getString("phone")+"\n";
}
Log.d("JSON DATA:", name);
Log.d("JSON DATA:", phone.toString());
}
catch (JSONException e)
{
e.printStackTrace();
Log.d("JSON ERROR", e.getLocalizedMessage());
}
}
Try this
JSONArray phoneJson = tt.getJSONArray("phone");
String[] arr = new String[phoneJson.length()];
for(int i = 0; i < phoneJson.length(); i++)
arr[i] = phoneJson.getString(i);
Filter number from Array of string and get the index of last two greater number in android
I have a ArrayList that has value like [Value,Sum3,121,data8input,in:21::7,7.00,9.01] and I want to extract only number as the output should be like this [3,121,8,21,7,7.00,9.01] and then have to rearrange ascending and then get the index of last two number as result will be [21,121].
My tried code below,
for (int i = 0; i < arrayString.size(); i++) {
Pattern p = Pattern.compile("-?\\d+(,\\d+)*?\\.?\\d+?");
List<String> numbers = new ArrayList<String>();
Matcher m = p.matcher(arrayString.get(i).getvalue);
numbers.addAll(m);
for (int j = 0; j < numbers.size(); j++) {
Log.d("REMEMBERFILTER", allCollection.get(i).getTextValue());
}
}
}
do something like this, though it is not exactly memory efficient as I am using another list.
ArrayList<String> tempList = new ArrayList<>();
for (int i = 0; i < yourArrayList.size(); i++) {
tempList.add(yourArrayList.get(i).replaceAll("[^0-9]", ""));
}
//Arrange in ascending order
Collections.sort(tempList);
//Also try to remove those indexes which has only letters with
tempList.removeAll(Arrays.asList("", null));
for (int i = 0; i < tempList.size(); i++) {
Log.d("+++++++++", "" + tempList.get(i));
}
//You can get the last two or any element by get method of list by //list.size()-1 and list.size()-2 so on
This is a way to do it, finalArray has the 2 numbers you want:
String[] str = new String[] {"Value", "Sum3", "121", "data8input", "in:21::7", "7.00,9.01"};
StringBuilder longStringBuilder = new StringBuilder();
for (String s : str) {
longStringBuilder.append(s).append(" ");
}
String longString = longStringBuilder.toString();
String onlyNumbers = " " + longString.replaceAll("[^0-9.]", " ") + " ";
onlyNumbers = onlyNumbers.replaceAll(" \\. ", "").trim();
while (onlyNumbers.indexOf(" ") > 0) {
onlyNumbers = onlyNumbers.replaceAll(" ", " ");
}
String[] array = onlyNumbers.split(" ");
Double[] doubleArray = new Double[array.length];
for (int i = 0; i < array.length; i++) {
try {
doubleArray[i] = Double.parseDouble(array[i]);
} catch (NumberFormatException e) {
e.printStackTrace();
doubleArray[i] = 0.0;
}
}
Arrays.sort(doubleArray);
int numbersCount = doubleArray.length;
Double[] finalArray;
if (numbersCount >= 2) {
finalArray = new Double[]{doubleArray[numbersCount - 2], doubleArray[numbersCount - 1]};
} else if (numbersCount == 1) {
finalArray = new Double[]{ doubleArray[0]};
} else {
finalArray = new Double[]{};
}
for (Double number : finalArray) {
System.out.println(number);
}
Nested JSONArray Record Parsing Issue Android
I am making a App which receives a JSON Data From Server, User will select a value from Spinner like 0,1,2... and so on, On the Basis of number selection JSON will return a data from user defined index like 0,1.. i don't know how to parse a inner JSON Data in Android
json = new JSONObject(JSONParser.Result);
JSONArray jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
Log.d("JSON Algo Result", json.toString());
if (jArray!=null) {
for (int i = 0; i < jArray.length(); i++) {
jsonarray = jArray.getJSONArray(i);
if (jsonarray != null) {
for (int j = 0; j < jsonarray.length(); i++){
if(i==0) {
jsonarray = jArray.getJSONArray(j);
_stop.setName(jsonarray.getString(0));
StopElement.Stop_name_list.add(_stop.getName());
}
}
} else {
break;
}
}
} else {
return null;
}

How to sort/order JSON output?
I have a JSON loop and I am able to get objects in the loop, but the problem is my output is not in order:
My expected output is:
Menu Id 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23
but I get results like:
Menu Id: 19,18,23,16,17,14,15,12,13,21,20,22,4,3,11,2,1.
How can I sort this the way I expect?
JSONArray values = menuObject.toJSONArray(names);
for (int i = 0; i< values.length(); i++) {
JSONObject json2 = (JSONObject) values.getJSONObject(i);
//int menu_id = json2.getInt("menu_id");
menu_id = json2.getString("menu_id");
int m_id = Integer.parseInt(menu_id);
if (json2.has("menu_parent")) {
menu_parent = json2.getString("menu_parent");
}
if (m_id < 0) {
//
} else {
id = id + menu_id + ",";
int menu_category = Integer.parseInt(menu_parent);
System.out.println("Menu Id" + id);
if (json2.has("menu_name")) {
menu_list = json2.getString(KEY_MENU).trim();
System.out.println("Menu List" +menu_title);
menu_title = menu_title + menu_list + ",";
}
}
}
I think you can get it sorted this way:
Collections.sort("your data", new Comparator<Item>() {
public int compare(Item i1, Item i2) {
return i1.getCaption().compareTo(i2.getCaption());
}
});
After this is done, it should be sorted out.
Try this:
String menuids = "19,18,23,16,17,14,15,12,13,21,20,22,4,3,11,2,1";
String[] ids = menuids.split(",");
Integer[] result = new Integer[ids.length];
for (int i = 0; i < ids.length; i++) {
result[i] = Integer.parseInt(ids[i].trim());
}
Collections.sort(Arrays.asList(result));
StringBuilder sb = new StringBuilder();
for (int i = 0; i < result.length; i++) {
Integer intValue = result[i];
sb.append(intValue);
if (i < result.length - 1) {
sb.append(", ");
}
}
String finaldata = sb.toString();
System.out.println(finaldata);
Initialize the value of a arraylist
I can't understand what is wrong in my code . I am getting error in myAddressUniqueness. don't know why.Before i have tried it with string data type but got the same error. It is saying java.null exception.
ArrayList<String> myAddressUniqueness = null;
String name = "hello";
if (indexBody < 0 || !cursor.moveToFirst())
return;
smsList.clear();
do {
// int cursorPostion = cursor.getPosition();
String address;
String msgStr = cursor.getString(indexBody);
String senderNumber = cursor.getString(indexAddr);
Log.d("Name : ", senderNumber);
// String name = cursor.getString(cursor
// .getColumnIndex(PhoneLookup.DISPLAY_NAME));
// Log.d("Name : ",name);
if (name != null) {
address = name;
} else {
address = senderNumber;
}
Log.d("Address: ", address);
flag = 1;
//Log.e("Number: ", addressUniqueness.length + "");
for (j = 0; j < myAddressUniqueness.size(); j++) {
if (myAddressUniqueness.contains(address)) {
flag = 0;
break;
}
}
if (flag == 1) {
myAddressUniqueness.add(new String(address));
i++;
String str = "Sender: " + address + "\n";
smsList.add(str);
}
// TODO Auto-generated catch block
} while (cursor.moveToNext());
Change your declaration to ArrayList<String> myAddressUniqueness = new ArrayList<String>(); You have it initialized to null. This will instantiate it then you can add data to it.
You should instantiate myAddressUniqueness by myAddressUniqueness = new ArrayList<String>() before using it.
