We Keep Coding

I add data into list from API server but size of the list is zero why?

I am adding data into the list from model class object still it is showing list size is zero:
apiService.getOrdersDateWise(dateFrom,dateTo).enqueue(new Callback<List<OrdersDateWiseModel>>() {
#Override public void onResponse(Call<List<OrdersDateWiseModel>> call, Response<List<OrdersDateWiseModel>> response) {
List<OrdersDateWiseModel> ordsList = response.body();
int ordsListSize = ordsList.size();
Log.i(TAG, "OrdersListSize 250 : " + ordsListSize);
if (ordsList.size() != 0) {
if (fromDateMillisecs <= toDateMillisecs) {
for (int i = 0;i<ordsList.size();i++){
String ordDate = ordsList.get(i).getOrder_date();
String ordNo = ordsList.get(i).getOrder_number();
String ordValue = ordsList.get(i).getOrder_value();
String retaId = ordsList.get(i).getRetailer_id();
String shopName1 = ordsList.get(i).getShop_name();
String retName1 = ordsList.get(i).getRetailer_name();
String area1 = ordsList.get(i).getArea();
String phone1 = ordsList.get(i).getPhone();
getOrdersList.add(
new OrdersDateWiseModel(
ordDate,
ordNo,
ordValue,
retaId,
shopName1,
retName1,
area1,
phone1
));
}
ordersDateWiseAdapter.notifyDataSetChanged();
I expected output is the size of the list:
I/OrdersDateWiseActivity: OrdersListSize 250 : 0

I need my counter to stop counting and display a toast when it reaches 510

This is the math part at the moment, i have one of these for each text view element, and it counts fine, all i need is for the numbers in all of the text views to stop counting when the total reaches 510 and all the others to stop counting when they reach 252 individually
when the total reaches 510 and/or when the individual values reach 252 i want a toast displaying "Highest number reached" or something like that
This is Java if anyone doesn't know, and it's in android studio
private View.OnClickListener hpListener = new View.OnClickListener() {
public void onClick(View view) {
// Spinner element
Spinner spinner = (Spinner) findViewById(R.id.evval);
// TextView element
TextView HPtx = (TextView) findViewById(R.id.hpval);
TextView atttx = (TextView) findViewById(R.id.attval);
TextView deftx = (TextView) findViewById(R.id.defval);
TextView satx = (TextView) findViewById(R.id.saval);
TextView sdtx = (TextView) findViewById(R.id.sdval);
TextView spdtx = (TextView) findViewById(R.id.spdval);
TextView totaltx = (TextView) findViewById(R.id.totalval);
// Ev values
int add = Integer.parseInt(spinner.getSelectedItem().toString());
// Calculation
int HP = Integer.parseInt(HPtx.getText().toString());
int att = Integer.parseInt(atttx.getText().toString());
int def = Integer.parseInt(deftx.getText().toString());
int sa = Integer.parseInt(satx.getText().toString());
int sd = Integer.parseInt(sdtx.getText().toString());
int spd = Integer.parseInt(spdtx.getText().toString());
int hptotal = HP + add;
int total = hptotal + att + def + sa + sd + spd;
// Value calculations
DecimalFormat addHPFormat = new DecimalFormat("000");
DecimalFormat addtotalFormat = new DecimalFormat("000");
HPtx.setText(addHPFormat.format(hptotal));
totaltx.setText(addtotalFormat.format(total));
}
};

Just Place this in your code after total:
if(total >= 510 || hp >=252 || att >=252 || def >=252 || sa >=252 || sd >=252 || spd >=252)
Toast.makeText(this,"highest Number Reached",Toast.LENGTH_SHORT).show();
else {
DecimalFormat addHPFormat = new DecimalFormat("000");
DecimalFormat addtotalFormat = new DecimalFormat("000");
HPtx.setText(addHPFormat.format(hptotal));
totaltx.setText(addtotalFormat.format(total));
}

private View.OnClickListener hpListener = new View.OnClickListener() {
public void onClick(View view) {
// Spinner element
Spinner spinner = (Spinner) findViewById(R.id.evval);
// TextView element
TextView HPtx = (TextView) findViewById(R.id.hpval);
TextView atttx = (TextView) findViewById(R.id.attval);
TextView deftx = (TextView) findViewById(R.id.defval);
TextView satx = (TextView) findViewById(R.id.saval);
TextView sdtx = (TextView) findViewById(R.id.sdval);
TextView spdtx = (TextView) findViewById(R.id.spdval);
TextView totaltx = (TextView) findViewById(R.id.totalval);
// Ev values
int add = Integer.parseInt(spinner.getSelectedItem().toString());
// Calculation
int HP = Integer.parseInt(HPtx.getText().toString());
int att = Integer.parseInt(atttx.getText().toString());
int def = Integer.parseInt(deftx.getText().toString());
int sa = Integer.parseInt(satx.getText().toString());
int sd = Integer.parseInt(sdtx.getText().toString());
int spd = Integer.parseInt(spdtx.getText().toString());
int hptotal = HP + add;
int total = hptotal + att + def + sa + sd + spd;
if (total >= 510 || add >= 253 || att >= 252 || def >= 252 || sa >= 252 || sf >= 252 || spd >= 252) {
// Replace MainActivity.this with your context
Toast.makeText(MainActivity.this, "Highest number reached", Toast.LENGTH_SHORT).show();
return;
}
// Value calculations
DecimalFormat addHPFormat = new DecimalFormat("000");
DecimalFormat addtotalFormat = new DecimalFormat("000");
HPtx.setText(addHPFormat.format(hptotal));
totaltx.setText(addtotalFormat.format(total));
}
};

Android ArrayList without first value

I have problem with ArrayList. I have the question files structure like:
Y aaaaaa.
Y bbbbbb.
N ccccccc.
N ddddddd.
and I want to put into textview3 the first letter like Y or N
public void value (){
Scanner answerScanner = new Scanner(getResources().openRawResource(R.raw.answer));
Scanner questionScanner = new Scanner(getResources().openRawResource(R.raw.question));
ArrayList<String> answerList = new ArrayList<String>();
ArrayList<String> questionList = new ArrayList<String>();
try {
while (answerScanner.hasNextLine() ) {
answerList.add(answerScanner.nextLine());
questionList.add(questionScanner.nextLine());
}
} finally {
answerScanner.close();
questionScanner.close();
}
int nextInt = random.nextInt(questionList.size());
String answerString = answerList.get(nextInt);
String questionString = questionList.get(nextInt);
yourAnswerString = answerString.substring(0);
yourQuestionString = questionString.substring(2);
shortform = questionString.substring(0,1);
TextView textGenerateNumber = (TextView)findViewById(R.id.textView1);
TextView textGenerateNumber2 = (TextView)findViewById(R.id.textView2);
TextView textGenerateNumber3 = (TextView)findViewById(R.id.textView3);
textGenerateNumber.setText(yourQuestionString);
textGenerateNumber2.setText(yourAnswerString);
textGenerateNumber3.setText(shortform);
}
then I add:
shortform = questionString.substring(0,1);
TextView textGenerateNumber3 = (TextView)findViewById(R.id.textView3);
textGenerateNumber3.setText(shortform);
I get good answers I all cases without first .... when radom get first line from text file I get empty value ( my textView3 are empty).

why i get null when intent double value

I need to intent a double value in order to insert in SQLite but when i print output it show NULL value.
This is code intent in first Activity
Intent intent = new Intent(Process.this,AddStudent.class);
intent.putExtra("Intent", result);
startActivity(intent);
and this is code get intent in another activity
String concentrate = getIntent().getStringExtra("Intent");
Here is full code.
FirstActivity;
public class Process extends Activity {
public static double a,b,r,std_err = 0.0;
public static double e;

sumXY = sumXY + (oat[i]*(Math.log(energy[i])));
}
b = ((N*sumXY) - (sumX*sumY))/(N*sumX2 - (sumX*sumX));
a = Math.pow(e, (sumY - (b*sumX))/N);
Double c = 0.00; // numerator
Double d = 0.00; // denominator
c = (b)*(sumXY - sumX*sumY/N);
d = sumY2 - (sumY*sumY)/N;

if(r > 0){
p = Math.sqrt(r);
} else {

}
std_err = Math.sqrt((d-c)/(N-2));

You have
double result = Math.pow(2.71828182845904,x[0]*b);
and
intent.putExtra("Intent", result);
result is a double.
But when you retrieve you have
String concentrate = getIntent().getStringExtra("Intent");
Instead you should use
double concentrate = getIntent().getDoubleExtra("Intent", 0);
Reference :
http://developer.android.com/reference/android/content/Intent.html#getDoubleExtra(java.lang.String, double)

You're not actually placing your double value into your Intent. You need to use putDouble and getDouble methods.
Intent intent = new Intent(Process.this,AddStudent.class);
Bundle b = new Bundle();
b.putDouble("Intent", result);
intent.putExtras(b);
startActivity(intent);
Then, get it in your next Activity:
Bundle b = getIntent().getExtras();
double result = b.getDouble("Intent");

String concentrate = getIntent().getStringExtra("Intent");
Should be like this:
double concentrate = getIntent().getExtras().getDouble("Intent");
Wrap the passed bundle directly into double.

You are passing a Double value and trying to get a String value so you are getting null
Replace
getIntent().getStringExtra("Intent");
with
getIntent().getDoubleExtra("Intent", 0);

Try putting your double into a bundle, then passing like so
Intent intent = new Intent(Process.this,AddStudent.class);
Bundle extras = new Bundle();
intent.putExtras(b);
startActivity(intent);
Then, in your new activity
Bundle extras = Intent.getExtras();
Double result = extras.getDouble("Intent");

the postExecute method of AsyncTask not working properly

If I run above and below code in separate projects, it works. But when I try integrate them, the graph is not getting populated.
The reason I feel is in postExecute method because
One important thing to notice is when I run any other random project, make some change in it, and relaunch the app then for some moments Graph.java is visible as it is in background. At that moment, output is coming perfectly.
But if I run the Graph.java , it's showing blank graph.
EDIT
{{ 1st code is to fetch data from URL and store it in various arrays.
2nd code is to diaplay data on graph.
In below code the two arrays passed to graph contain static values, they should take the values from the 1st code. }}

I created another class for plotting graph.
Call that class from current class by using intent. Passed the two arrays to graph class by using intent property. plotted the graph in 2nd activity using two arrays.
