I've tried to retrieve RSS data from Yahho weather ,however my code couldn't work.
May I know what's wrong with it?
The Url that I've use is http://weather.yahooapis.com/forecastrss?w=1062617&u=c.
I'm a newbie in programming, Kindly seek your advice to it.
Thanks
the below are my coding.

everyone. I have an ArrayList of the data and a ListView to showing up the list of the data. Now what I want to do is rearrange the data when I press the button and sort the data in which data has the highest result.
Here is my code:
public class MainActivity extends AppCompatActivity {
private TextView mTextMessage;
String[] dataDetail;
ArrayList<dataDetail> allDetail = new ArrayList<>();
ListView detailList;
final Context context = this;
final int min = 0;
final int max = 10;
final int random = new Random().nextInt((max - min) + 1) + min;
Button reorder = findViewById(R.id.arrangeId);
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
mTextMessage.setText(R.string.title_home);
return true;
case R.id.navigation_dashboard:
mTextMessage.setText(R.string.title_dashboard);
return true;
}
return false;
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
detailList = findViewById(R.id.dataView);
mTextMessage = (TextView) findViewById(R.id.message);
BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
new GetData().execute();
}
private class GetData extends AsyncTask<Void, Void, ArrayList<dataDetail>> {
protected ArrayList<dataDetail> doInBackground(Void... voids) {
HttpURLConnection urlConnection;
InputStream in = null;
try {
URL url = new URL("http://10.0.2.2:8080/projectServer/DataDetailDB?getdata=true");

String response = convertStreamToString(in);
System.out.println("Server response = " + response);
try {

dataDetail = new String[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {
final String customerName = jsonArray.getJSONObject(i).get("customerName").toString();
final String carName = jsonArray.getJSONObject(i).get("carName").toString();
final String appointmentDate = jsonArray.getJSONObject(i).get("appointmentDate").toString();
final String email = jsonArray.getJSONObject(i).get("email").toString();
final String issueDescribe = jsonArray.getJSONObject(i).get("issueDescribe").toString();
final String timeForJob = jsonArray.getJSONObject(i).get("timeForJob").toString();
final String costForJob = jsonArray.getJSONObject(i).get("costForJob").toString();
final String reliableOnCar = jsonArray.getJSONObject(i).get("reliableOnCar").toString();
final String distanceJob = jsonArray.getJSONObject(i).get("distance").toString();
dataDetail tData = new dataDetail(customerName, carName, appointmentDate, email, issueDescribe, timeForJob, costForJob, reliableOnCar, distanceJob);
allDetail.add(tData);
System.out.println("customername = " + customerName + "carname = " + carName + "appointmentdate = " + appointmentDate +

+ "dis = " + distanceJob);
dataDetail [i] = "Name: " + customerName + "\n" + "Appointment Date: " + appointmentDate;
reorder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
float finalResult = random * Float.parseFloat(timeForJob) + random * Float.parseFloat(reliableOnCar) +
random * Float.parseFloat(distanceJob) + random * Float.parseFloat(costForJob);
System.out.print("Test result " + finalResult + " ");
/* Trying to sort the data here which has the highest finalResult
* will going to the top of the list */
allDetail = new ArrayList<String>(Arrays.asList(dataDetail));
Collections.sort(allDetail);
ArrayAdapter newList = new ArrayAdapter(context, android.R.layout.simple_list_item_1, dataDetail);
newList.setAdapter(theList);
}
});
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(ArrayList<dataDetail> dataDetailArrayList) {
super.onPostExecute(dataDetailArrayList);
ArrayAdapter theList = new ArrayAdapter(context, android.R.layout.simple_list_item_1, dataDetail);
detailList.setAdapter(theList);
}
}
public String convertStreamToString(InputStream is) {
java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
return s.hasNext() ? s.next() : "";
}
}
But when I try to use sort I get the error says it's incompatible types.
allDetail = new ArrayList<String>(Arrays.asList(dataDetail));
Collections.sort(allDetail);
The finalResult will do the calculation and get the final result for every data it retrieves from the database. And now I just want to reorder it automatically, This is the logcat:
Please anyone can help how can I do the rearrange for the listview?
Collections.sort() will work. Its your problem related to how your are storing your data in list
I'am a beginner in android and i use AndroidStudio
I have a problem

The mistake that you have made is that you assume that
import static com.example.saiid.listecompte.fetchcompte.dataParsed;
will automatically just be the dataParsed Variable you need. What that line does is that it gets the default value of dataParsed (from a default fetchcompte instance). Since you make another instance of a fetchcompte object [called process] (which you are using to populate its dataParsed variable) simply access the dataParsed variable of that instance.
So instead of using:
textView_type.setText(dataParsed[i]);
You can use:
textView_type.setText(process.dataParsed[i]);
But to do this you will need to somehow access the process variable in your adapter class.
I have image like this for example:
Recylerview2 inside Recylerview1
In this case:
If I click on the number 1 of list item, then recylerview2 will appear below a number 1
So my question is:
How can i do that? and this is my code.
Ive this code inside onBindViewHolder inside adapter.
fItemsHolder.mLinearReply.setVisibility(View.GONE);
if (item.getName2() != null) {
fItemsHolder.mHiddenComment.setText(item.getName2()+": "+item.getComment2());
fItemsHolder.feedImageView.setVisibility(View.VISIBLE);
int jComment = Integer.parseInt(item.getJumlahComment().toString());
if( jComment > 0){
fItemsHolder.mHiddenComment.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
commentItems = new ArrayList<CommentModel>();
adapter = new NoteCommentListAdapter(mContext, commentItems);
mRecyclerView = new RecyclerView(mContext);
getListViewComments(item.getUserid(), item.getId(),fItemsHolder,i, commentItems, adapter, mRecyclerView);
commentItems = new ArrayList<CommentModel>();
adapter = new NoteCommentListAdapter(mContext, commentItems);
mRecyclerView.setAdapter(adapter);
}
});
}
} else {
fItemsHolder.mHiddenComment.setVisibility(View.GONE);
fItemsHolder.mLinearHiddenComment.setVisibility(View.GONE);
}
And this is my asynctask:
private void getListViewComments(final String userid, String id_note,final feedItemsHolder feedItemsHolder, int i, final List<CommentModel> commentItems, final NoteCommentListAdapter adapter, final RecyclerView mRecyclerView) {
class ambilComment extends AsyncTask<String, Void, String> {

Try using this library: android-advancedrecyclerview
Check this example on how to use expandable recyclerview using this lib.
To use it, add the lib to your project by adding a dependency for it in the gradle.build file as:
dependencies {
compile ('com.h6ah4i.android.widget.advrecyclerview:advrecyclerview:0.9.1#aar'){
transitive=true
}
}
I am new to Android. I'm trying to sort by the date in the JSON data, but nothing works. I'm not even getting an error. I've tried so many different ways, but its not working.
I did a lot of searching but could not figure out how to implement this. How can I sort this by the days column? Thank you in advance.
Here's my code
public class ParseJSONTask extends AsyncTask< Void , Void , Void > {

private static String TAG_OSMS = "osms";
private static String TAG_ISMS = "isms";

super.onPreExecute();
services = new ArrayList<ServiceData>();

WebServiceHandler webServiceHandler = new WebServiceHandler();
String JsonStr = webServiceHandler.getJSONData("http://jsonblob.com/55e34310e4b01190df36e861");
try {
JSONObject jsonObject = new JSONObject(JsonStr);
final JSONArray contactsJSON = jsonObject.getJSONArray(TAG_SERVICES);
for (int i = 0; i < contactsJSON.length(); i++) {
ServiceData aServiceData = new ServiceData();
//json parse istedimiz veriyi kullanabiliriz.
JSONObject serviceObject = contactsJSON.getJSONObject(i);
aServiceData.id = serviceObject.getString(TAG_ID);
aServiceData.command = serviceObject.getString(TAG_COMMAND);
aServiceData.days = serviceObject.getString(TAG_DAYS);
aServiceData.hours = serviceObject.getString(TAG_HOURS);
aServiceData.osms = serviceObject.getString(TAG_OSMS);
aServiceData.isms = serviceObject.getString(TAG_ISMS);
aServiceData.timeout = serviceObject.getString(TAG_TIMEOUT);
String input = aServiceData.days + " " + aServiceData.hours;
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm").parse(input);
long milliseconds = date.getTime();
final long millisecondsFromNow = milliseconds - (new Date()).getTime();
aServiceData.milliseconds = milliseconds;
services.add(aServiceData);
if(millisecondsFromNow > 0) {
new DateSendSMS().onCreate(aServiceData.days, aServiceData.hours, aServiceData.osms, aServiceData.command);
Thread.sleep(Integer.parseInt(aServiceData.timeout) * 60000);
}
//Timeout aşağı kısımda sürelendirilecek
}

}
Collections.sort(services, new Comparator<ServiceData>() {

return t1.milliseconds <= t2.milliseconds ? -1 : 1;
}
});
// here is sorted data
for (ServiceData aServiceData : services) {
// move DateSendSMS here. above you can add additional logic about millis
new DateSendSMS().onCreate(aServiceData.days, aServiceData.hours, aServiceData.osms, aServiceData.command);
Log.d("+++++", aServiceData.toString());
}
}
}
ServiceData Class:
public static class ServiceData {
public long milliseconds;
public String id = "";
public String command = "";
public String days = "";
public String hours = "";
public String osms = "";
public String isms = "";
public String timeout = "";
#Override
public String toString() {
return id + ", " + command + ", " + days + ", " + hours + ", " + osms + ", " + isms
+ ", " + timeout + "\n \n ";
}
}
Add time field to ServiceData class
ServiceDate {
...
long milliseconds;
...
}
Fill this field in for loop:
long milliseconds = date.getTime();
aServiceData.milliseconds = milliseconds;
Sort services in onPostExecute
Collections.sort(services, new Comparator<ServiceData>() {
#Override
public int compare(ServiceData t1, ServiceData t2) {
return t1.milliseconds <= t2.milliseconds ? -1 : 1;
}
});
I am not sure you can directly sort Json Data (I dont know weather there is a library that will actually do it - if so go for it). I Suggest you to put all the ServiceData into a collection (Which you do at the moment) and then Sort it.
You can write your own sorting algorithm or you can use a Java Collections library to do the sorting by implimention Comparable on your ServiceData class or using a Comparable and them you can use Colletions.sort() to sort your list.
Here is a good tutorial.
What I wanted to have is to collect all the results in an ArrayList and iterate in that arraylist and display the result but when I try to run the code below, it only return one element...
I have 3 classes...

This is the sample XML file...
<result>
<name>Zaaffran Restaurant - BBQ and GRILL, Darling Harbour</name>
<vicinity>Harbourside Centre 10 Darling Drive, Darling Harbour, Sydney</vicinity>
<type>restaurant</type>
<type>food</type>
<type>establishment</type>
<geometry>
<location>
<lat>-33.8719830</lat>
<lng>151.1990860</lng>
</location>
</geometry>
<rating>3.9</rating>
</result>
What I want to achieve here is to iterate in the result but the result arraylist has only one element...please help me...
This should help you

EDIT Also I recommend using the generic LIST <T> instead of ArrayList<T> as follows
List<String> names = new ArrayList<String>();
....
....
for code optimization as the latter ArrayList<String> has memory occupancy. Its not a big issue but optimization is the fundamental step to check the magnitude of efficiency (with respect to time duration and memory) of a program.
