Single button multiple action in sequence

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) {}
});

how to keep min Age Limit in Android

Am building an demo app, in which I would like to allow people who are above 21yrs, how do I do this.
I want to take there DOB and calculate the age, with the current year. I want to use DatePicker, but messed up seeing different snippets. thanks

This is a simple code that will guide your to achieve what your are planning for.
It uses a button click to launch the DatePicker Dialog
Layout file
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.inducesmile.mydatepicker.MainActivity">
<EditText
android:id="#+id/display_dob"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="24dp"/>
<Button

android:layout_width="wrap_content"

Then the Activity class
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.Toast;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
private DatePickerFragment datePickerFragment;
private static Calendar dateTime = Calendar.getInstance();
protected static int mYear;
protected static int mMonth;

}
});
}
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

}
#Override

long selectDateInMilliSeconds = dateTime.getTimeInMillis();
Calendar currentDate = Calendar.getInstance();
long currentDateInMilliSeconds = currentDate.getTimeInMillis();
SimpleDateFormat simpleDate = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
String strDt = simpleDate.format(dateTime.getTime());
displayDOB.setText(strDt);
if (selectDateInMilliSeconds > currentDateInMilliSeconds) {
Toast.makeText(getActivity(), "Your birthday date must come before taday's date", Toast.LENGTH_LONG).show();
return;
}
long diffDate = currentDateInMilliSeconds - selectDateInMilliSeconds;
Calendar yourAge = Calendar.getInstance();
yourAge.setTimeInMillis(diffDate);
long returnedYear = yourAge.get(Calendar.YEAR) - 1970;
if (returnedYear < allowedDOB) {
Toast.makeText(getActivity(), "Sorry!!! You are not allowed to use this app", Toast.LENGTH_LONG).show();
return;
} else {
// move to another activity page
}
}
}
}

if you want to limit the age from datepicker itself you can do like this,
<com.deevita.patient.Custom_Layouts.editText
android:id="#+id/dob"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:drawableStart="#drawable/ic_date_icon"
android:drawablePadding="#dimen/drawable_padding"
android:focusable="false"
android:hint="#string/birthday"
android:inputType="date"
android:padding="#dimen/padding_common_new"
android:textSize="#dimen/font_small">
</com.deevita.patient.Custom_Layouts.editText>
add the following code in java
dob.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.YEAR,-21); // the age you want to limit
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
String date = String.valueOf(dayOfMonth) + "-" + String.valueOf(monthOfYear + 1)
+ "-" + String.valueOf(year);
dob.setText(date);
}
}, yy, mm, dd);
datePicker.getDatePicker().setMaxDate(calendar.getTimeInMillis());
datePicker.show();
}
});

if user entered age
driverage = edtdriverage.getText().toString();
else if ( Integer.parseInt(driverage)> 55 || Integer.parseInt(driverage)< 18) {
GlobalMethods.Toast(AddDriverActivity.this, getString(R.string.enter_driver_age_min));
cancel = true;
}
you can achieve by validation method also

Why does setText() cause TextView to be re-printed at the top of the screen?

[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.
Here is the full code of the activity:

Android Date Picker month as number

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.

How to pass data from date picker and spinner to another activity

I'm a beginning android developer.
I need to pass data from two date pickers and a spinner to another activity.
Can some one help me with this code:
package qi.com;
import java.text.DateFormat;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.DatePickerDialog.OnDateSetListener;
import android.app.Dialog;

import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.Toast;
//multi date input
public class CoaActivity extends Activity implements AdapterView.OnItemSelectedListener {
TextView selection;
TextView mDateStart;
TextView mDateEnd;
Button mPickStart;
Button mPickEnd;
Calendar startDate;
Calendar EndDate;
int mYear;
int mMonth;
int mDay;
//list menu
String[] items = {"Pendapatan","Biaya"};
static final int DATE_DIALOG_ID = 0;
private TextView activeDateDisplay;

Spinner spin= (Spinner) findViewById(R.id.spinner);
spin.setOnItemSelectedListener(this);
ArrayAdapter<String> aa= new ArrayAdapter<String> (this, android.R.layout.simple_spinner_item, items);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(aa);
//capture view elements
mDateStart = (TextView) findViewById(R.id.DateStar);

}

break;
}
}
public void onItemSelected(AdapterView<?> parent, View v, int position, long id) {
selection.setText(items[position]);
Intent grid=new Intent(this, Grid.class);
this.startActivity(grid);
//send to another activity
//Detail(items[position]);
}

}

Intent grid=new Intent(this, Grid.class);
grid.putExtra("IDP", id);
this.startActivity(grid);
//Toast.makeText(this, "list : " , Toast.LENGTH_SHORT).show();
}
}
This is the xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Mulai dari :" />
<TextView
android:id="#+id/DateStar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="" />
<Button
android:id="#+id/btn_PickDateStart"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Tanggal Awal" />
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Sampai dengan :" />
<TextView
android:id="#+id/DateEnd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="" />
<Button
android:id="#+id/btn_PickDateEnd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Tanggal Akhir" />
<TextView
android:id="#+id/selection"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<Spinner
android:id="#+id/spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false" />
</LinearLayout>

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