android studio app case insensitive search from sqlite

android studio app case insensitive search from sqlite - android

I am working on a android application with sqlite database that store lots of standard english texts that have uppercase and lowercase words and it shows on the app, we have a search that right now is case sensitive and scroll between them with cursor
How I can return search string case insensitive from sqlite
this is my code on database
public List<String> getSearchedParagraph(String p) {
String sectionId = "";
List<String> result = new ArrayList<String>();
String query = "SELECT Distinct(sectionId) FROM paragraph where txt Like '%"
+p+ "%'";
Cursor cursor = db.rawQuery(query, null);
if (cursor != null && cursor.getCount() > 0) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
result.add(cursor.getString(0));
cursor.moveToNext();
}
}
return result;
}
i tested String query = "SELECT Distinct(sectionId) FROM paragraph where txt Like '%" +p+ "%' COLLATE NOCASE"; but still no change
UPDATE1 this is setWordSearch function:
public void setWordSearch(String str) {
wordSearch = str;
for (FragmentPage page : fragments) {
page.wordSearch = str;
}
notifyDataSetChanged();
}
UPDATE2 This is the FragmentPage:

thanks

as #CL mentioned, you can use Patterns,
just replace this code:
if (wordSearch != null && !wordSearch.equals("")) {
startIndex = str.indexOf(wordSearch);
while (startIndex != -1) {
sb.append(str.substring(subStringStart, startIndex)
+ "<span style=\"background-color:#ffff00\">"
+ str.substring(startIndex,
startIndex + wordSearch.length())
+ "</span>");
subStringStart = startIndex + wordSearch.length();
startIndex = str.indexOf(wordSearch, subStringStart);
}
sb.append(str.substring(subStringStart));
}
whit this:
Boolean wasFound;
if (wordSearch != null && !wordSearch.equals("")) {
Matcher subMatcher = Pattern.compile(Pattern.quote(wordSearch), Pattern.CASE_INSENSITIVE).matcher(str);
wasFound = subMatcher.find();
while (wasFound) {
startIndex = subMatcher.start();
sb.append(str.substring(subStringStart, startIndex)
+ "<span style=\"background-color:#ffff00\">"
+ str.substring(startIndex,
startIndex + wordSearch.length())
+ "</span>");
subStringStart = startIndex + wordSearch.length();
wasFound = subMatcher.find();
}
sb.append(str.substring(subStringStart));
}
I hope that this help you #n3tg33k ;)

You are using String.indexOf for searching. This function is case sensitive.
You need to search for the substring while ignoring case.

you can achieve it in this way....
public List<String> getSearchedParagraph(String p) {
p=p.toLowerCase();
String sectionId = "";
List<String> result = new ArrayList<String>();
String query = "SELECT Distinct(sectionId) FROM paragraph where LOWER(txt) Like '%"
+p+ "%'";
Cursor cursor = db.rawQuery(query, null);
if (cursor != null && cursor.getCount() > 0) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
result.add(cursor.getString(0));
cursor.moveToNext();
}
}
return result;
}

I have assigned Child Question ID using setChildQuestionID(). For Group Name 0, I get 0, 1, 2 on each child click. However, for Group Name 1, I get 4 for Sub Group Name 2a & 7 for Sub Group Name 2b for each of there child item click. Ideally, it should return whatever I set for them.

Do you mean that you want to get 0, 1, 2 for child clicks in group name 1? As far as I can tell, you're going to have to re-set the value of index to 0 to get that. At least, assuming you've defined index = 0 somewhere outside your outermost for-loop (I can't see where in your code you've set the value of index). Right now in Group 0, you have:
for (int k = 0; k < 2; k++) {
V_ChecklistChildItemModel v_checklistChildItemModel = new V_ChecklistChildItemModel();
v_checklistChildItemModel.setChildItemQuestionID("" + (k + 1));
v_checklistChildItemModel.setChildItemQuestionName("Description of Question " + (k + 1));
v_checklistChildItemModel.setChildQuestionID("" + index);
index++;
If index was 0 to start with, the value of index is now greater than 0. You don't set it back to 0, so when you get to the next cycle through your top-level for loop, the value of index is already > 0. If you want to start over at index = 0 in Group 1, you'll have to set the value of index back to 0.
In other words, you are returning exactly what you set for the questionIDs, but I think you're setting a number that you didn't want to set.

Sectioning date header in a ListView that has adapter extended by CursorAdapter

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

Get the item index of a listview and delete it on the listview and on my database

I'm now currently working on a project that lets the user view the list of a certain table and has the privilege of either editing or deleting it. There's no error, I just don't have any idea on what to do. Maybe anyone could help me on even just the delete feature? Giving a sample code would be so much helpful. Here's my code:

You can use this
sql_lite_db_obj.delete(tablename, whereClause, whereArgs)
For your convenience i edited my answer
public void clickHandler(View v) {
if (v.getId() == R.id.deleteOrder) {
int _id = 0;
try {
_id = (Integer) v.getTag(R.id.orderTitle);
} catch (Exception e) {
e.printStackTrace();
}
dh.delete(DatabaseHelpere.TableNAME, "_id=?",new String[] { String.valueOf(_id) });
}
}

When i look at the logcat i that the position log is always 0.
Why position is not increasing?

You are not returning from getItem() correctly:
public Object getItem(int position) {
return position;
}
It should be:
public Object getItem(int position) {
return valuesArray.get(position);
}

you have wrong in getItem()
public Object getItem(int position) {
return valuesArray.get(position);
}
it should return an Object not an the position, so basically it is always returning 0

This Program Was Made in AIDE on an android netbook.
It Crashes On Button Click. I was wondering what I Was doing wrong.
I tried before with runnables but it crashed then too. I'm new to
android development but I am fluent in Java. I noticed there are
alot of differences between android and Java.

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

android studio app case insensitive search from sqlite - android

You are using String.indexOf for searching. This function is case sensitive. You need to search for the substring while ignoring case.
