I am using a single button to do two task.
1.Date Selection
2.Difference between two dates
As-is:
I am using 'onclick' method for two button.
btnDate2 using to select the date and onclick is(setDate2)
button9 using to calculate the difference between two dates and onclick is(diff)
To-be:
One button for selecting the date and calculate the difference between two dates.And it should be in sequence.ex:
1: Select date
2. Calculate the difference between dates
Current code:

with amended code.
With 1st Click ,
After selecting ok.
Now again i should click the calc button to know the days difference.
What i need is 1st click the date and select "ok" upon choosing the date.i should be able to see the days difference upon clicking "ok" as per screen instead of pressing again the button.
Requirement 3:
When edittext2 number is exceeds vs spinner2 number then edittext2 color should change it to red color and some doast message
When edittext2 number is reaching to very near vs spinner2 number then edittext2 color should change it to yellow color and some doast message
1.Add below method into MainActivity.java:
public void dualFunctions(View view) {
if(view.getTag() == null) view.setTag("0");
if(view.getTag().equals("0")){
view.setTag("1");
view.setBackgroundColor(Color.GREEN);
setDate2(view);
}else{
view.setTag("0"); // Remove this line for one shoot.
view.setBackgroundColor(Color.YELLOW);
diff(view);
}
}
2.Change the button in layout to use this method.
The method toggles between date selection and calculation. If date selection is allowed for only once, then remove the line with comment.
Hope that helps!
Updated:
public void onDateSet(DatePicker view, int year, int month, int day) {
Button btnDate2 = (Button) getActivity().findViewById(R.id.btnDate2);
String stringOfDate = day + "." + (month + 1) + "." + year;
btnDate2.setText(stringOfDate);
MainActivity activity = (MainActivity)getActivity();
activity.diff(btnDate2);
}
For Requirement3:
Added if-else to check conditions.
private final static int VERY_NEAR_DATE = 30;
public void diff(View view) {
SimpleDateFormat myFormat = new SimpleDateFormat("dd.MM.yyyy");
CharSequence inputString1 = editTextDate5.getText();
try {
LocalDate date1 = LocalDate.parse(inputString1, dateFormatter);
CharSequence inputString2 = button2.getText();
try {
LocalDate date2 = LocalDate.parse(inputString2, dateFormatter);
long diffDate = ChronoUnit.DAYS.between(date1, date2);
txtResult.setText(String.valueOf(diffDate));
diffDate = (Long)ok2.getSelectedItem() - diffDate;
if(diffDate < 0){
txtResult.setTextColor(Color.RED);
Toast.makeText(this, "Date not allowed!!", Toast.LENGTH_SHORT).show();
}else if(diffDate < VERY_NEAR_DATE) {
txtResult.setTextColor(Color.YELLOW);
Toast.makeText(this, "Date too near!", Toast.LENGTH_SHORT).show();
}
} catch (DateTimeParseException dtpe) {
Toast.makeText(this, "Date2 is not a valid date: " + inputString2, Toast.LENGTH_SHORT).show();
}
} catch (DateTimeParseException dtpe) {
Toast.makeText(this, "Date1 is not a valid date: " + inputString1, Toast.LENGTH_SHORT).show();
}
}
If need to update views after selection changed in spinner, then add below code inside onCreate():
ok2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
diff(null);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {}
});

I have Set Two Date Pickers(Namely Check In and Check Out). For the first time when I run the app everything is fine,the date which I clicked is displayed in the TextView.But without running the app second time When I try to click the Check In button the date is not changing in the TextView. But the date is changing in the LogCat. At the same time the Check Out button is working fine for the first time and also with second time(without running the app again). Kindly solve my issue.

[edit] I have three sections: Title, Status, Priority, Time and Date, that are vertically aligned in that order. My problem is that when I setText() 'time' or 'date', the 'Priority' section and 'Time and Date' section get hoisted up. That is to say, the title of the 'Priority' section is completely align with the top bar and the 'Time and Date' title is right alongside it overlapping the content (instead of being below it).
The other two sections remain in their spot (at the top) but they are overlapped.
At the bottom are pictures.

Here is the method I use to set it. I played around by commenting stuff and with an inclusive OR, if I set the date text or the time text, it all gets hoisted up.

The problems in your code in this code
mStatusRadioGroup.setId(R.id.statusDone);
mPriorityRadioGroup.setId(R.id.medPriority);
In Android DatePicker, in some OS it shows Month as "Jan, Feb, Mar...Dec", on other it shows as 1,2,3..12
Is there a way to make it consistent througthout so that it should display 1,2,3.. 12 always as month?
Reason for displaying 1,2,3..12 instead of string is the localization support for various kind of languages.
Also is it advisable to do so?
Thanks.

In my application i have 3 text view arranged horizontally,1st previmage,2nd date,3rd nextimage.Now,when i click the 1st textview i should should display the previous month,(its printing) when once again i click means it should go to 2nd previous month of current month and this should go on..But when i click 2nd time it is coming the 1st previous month only its doesn't going backwards..Please help me.Thanks in advance..
This is my code:
prvmon.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View arg0)
{
// TODO Auto-generated method stub
System.out.println("Inside left");
TextView date=(TextView)findViewById(R.id.date);
Calendar cal= Calendar.getInstance();
cal.add(cal.MONTH,-1);
Date date1=cal.getTime();
System.out.println("sssssss="+date1);
cal.setTime(date1);
SimpleDateFormat month_date = new SimpleDateFormat("MMMMM yyyy");
String month_name = month_date.format(cal.getTime());
date.setText(month_name);
}
});
The reason is that you are initializing your Calender instance everytime. So, its taking the current date/time instance. So, better would be initialize in once and use it again. Declare it globally and initialize it in onCreate().
Calendar calendar = null;
protected void onCreate(Bundle savedInstanceState){
calendar = Calendar.getInstance();
...
}
now, use this calender instance in your onClick() event.
Date date1=cal.getTime();
you're always setting it to the same time and 'going back exactly one month into the past'. So, define your Date date1=cal.getTime() outside of the onClick OR keep track of how many months you need to substract, by e.g. incrementing some value at the end of the onClick().
EDIT:
ok so let's take a look at your code again
final int clicks = 0; //we'll use this to track clicks
prvmon.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View arg0)
{
int monthsToGo = --clicks;
// TODO Auto-generated method stub
System.out.println("Inside left");
TextView date=(TextView)findViewById(R.id.date);
Calendar cal= Calendar.getInstance();
cal.add(cal.MONTH, monthsToGo); //now it'll deduce -1 then -2 etc...
Date date1=cal.getTime();
System.out.println("sssssss="+date1);
cal.setTime(date1);
SimpleDateFormat month_date = new SimpleDateFormat("MMMMM yyyy");
String month_name = month_date.format(cal.getTime());
date.setText(month_name);
}
});
may be a full example will help:
import java.util.Calendar;
import java.util.Date;
import java.util.Locale;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MonthActivity extends Activity {
private Calendar calendar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
calendar = Calendar.getInstance();
calendar.setTime(new Date());
final TextView textView = (TextView) findViewById(R.id.dateTextView);
updateTextView(textView);
Button prev = (Button) findViewById(R.id.prevCmd);
prev.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
calendar.add(Calendar.MONTH, -1);
updateTextView(textView);
}
});
Button next = (Button) findViewById(R.id.nextCmd);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
calendar.add(Calendar.MONTH, 1);
updateTextView(textView);
}
});
}
private void updateTextView(TextView textView) {
textView.setText(""
+ calendar.getDisplayName(Calendar.MONTH, Calendar.SHORT,
Locale.getDefault()));
}
}

Use the long value that Date gives you, and put it in the extras, along with everything else you are sending to the activity.
