Develop Reference

I need to perform add to cart functionality with the option of increment or decrement quantity of item

product quantity changes button but when I click the add to cart button and change the visibility to gone others + , - buttons visibility to visible show on the screen then I click any of this two-button and their listener didn't work and after restarting the app both + , - buttons start working correctly. One more thing, I need my notification badge value shouldn't be changed if one product is already in the cart then changing its quantity, but in my case value change if I increase the quantity or decrease the quantity of the product. Thanks in advance

first time when adapter constructor called there is no data in the cartDataTables list and because of my condition if (cartDataTables != null && cartDataTables.size() > 0), when I click add to cart button they found no data in the cartDataTables list because I didn't call notifyDataSetChanged() method or call the adapter constructor again, and my addtocart click listener is inside this condition if (cartDataTables != null && cartDataTables.size() > 0) that's why add to cart button click listner didn't work.
solution: call the adapter constructor again.

Android Quiz App,back and next buttons issue

I am developing a quiz application,and im facing with a issue with back and next button. Here is the situation:
I have 40 questions in total,and in the java class of quiz i initialize an integer rowID=1

Thank You!

Your buttons' states are only updated once since the logic is in onCreate.
Consider transferring that logic into a function and call it in the button's onClick handler after updating the rowID.
For example
private void updateButtonState() {
if (rowID > 1 && rowID < 40) {
previous_question.setEnabled(true);
next_question.setEnabled(true);
} else if (rowID == 40) {
next_question.setEnabled(false);
} else if (rowID == 1) {
previous_question.setEnabled(false);
}
}
And in your onClick
#Override
public void onClick(View v) {
rowID = rowID - 1; // + 1 if next button
updateButtonState();
...
}

Suppose you have an input string s and the list of words you want to replace by asterisks:
String s = "i will hit your head right now";
List<String> words = Arrays.asList("head", "now"); // suppose these words are offensive
You just iterate over list of offensive words, looking if input string contains one, and perform a replacement. The simplest way to do this is by using regex:
for (String word : words) {
Pattern rx = Pattern.compile("\\b" + word + "\\b", Pattern.CASE_INSENSITIVE);
s = rx.matcher(s).replaceAll(new String(new char[word.length()]).replace('\0', '*'));
}
// s: i will hit your **** right ***
I've added \\b at the front and end of regex pattern to match just whole words (i. e. "head" will be processed, "header" will not). And this piece:
new String(new char[n]).replace('\0', c)
constructs a new string of n chars c.
After that, use resulting s wherever you need.

It is a basic about java, not android related. A way to do this is you make a list of your bad words and replace it from the string that user input. Refer to example below
String userInput = "this is an example of some bad words";
ArrayList<String> badWords = new ArrayList<>();
badWords.add("some");
badWords.add("bad");
badWords.add("words");
for (int i = 0; i < badWords.size(); i++) {
String badWord = badWords.get(i);
if(userInput.toLowerCase().contains(badWord)){
userInput = userInput.replace(badWord, "*****");
}
}

In AsyncTask, stop making registerReceiver() freeze the app

Since I finally figured out that the registerReceiver() method is usually running on the UI-Thread, I now want to change that. I just need some advice of how I could do that.
How would I be able to change registerReceiver() to stop freezing my app?
My doInBackground() method from the AsyncTask, runs another method that is using the registerReceiver(mReceiver, filter) method (both variables are already defined). But I want to keep seeing my ProgressDialog instead of making the app freezing.
I read about using a Handler and a new Thread, but I need some help there.
Thanks in advance.

Move it to onProgressUpdate() method, or better , onPostExecute()/onPreExecuteMethod() depending on your need.
These methods run on UI thread and not on the new thread creetaed by the Asynctask

You have to retrieve jsonArray from the jsonObject items. But in your code you have not used items anywhere. Try this way:
String jsonStr = new ConnectionService().connectionGet("http://newapi.bacaberita.com/berita","");
JSONObject jsonObject = new JSONObject(jsonStr);
System.out.println("..........JSON OBJECT.............");
System.out.println(jsonObject); // full json Object
JSONArray jsonArray = jsonObject.getJSONArray("items");
System.out.println("..........JSON ARRAY PARSING.............");
for(int i=0;i<jsonArray.length();i++)
{
String menu_id = jsonArray.getJSONObject(i).getString("Menu_ID");
String is_display = jsonArray.getJSONObject(i).getString("IsDisplay");
System.out.println("MENU_ID: "+menu_id);
System.out.println("IsDisplay: "+is_display);
}
The methods used in above example are as follows:
public static String connectionGet(String url, String parameter) throws MalformedURLException, ProtocolException, IOException {
URL url1 = new URL(url);
HttpURLConnection request1 = (HttpURLConnection) url1.openConnection();
request1.setRequestMethod("GET");
request1.connect();
String responseBody = convertStreamToString(request1.getInputStream());
return responseBody;
}
private static String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
} catch (IOException e) {
} finally {
try {
is.close();
} catch (IOException e) {
}
}
return sb.toString();
}
