java.lang.ClassCastException: Search cannot be cast to android.app.Activity

Hi does anyone know why i am getting this error in runtime? I am unsure how to resolve it and i am new to this. Please help! I have called the Search class in my MainActivity and my app crashes when i click on the button to open it.
Here is the code used to call the Search class:
search.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, Search.class);
startActivity(intent);
}
});
And here is my Search class:

Your Search class is a Fragment, you cannot start it with the Intent.
Make Search to be Activity or switch between fragments using FragmentManager.

Intent intent = new Intent(MainActivity.this, Search.class);
The Intent constructor doesn't expect a Fragment class as a second Argument, Here you add Search.class which is a Fragment, but you need to have an Activity instead
Fragments can be loaded in activities using a Transaction, not an intent.

How to get hour and minute from one timePickerDialog twice for start time and end time

timepickerdialog screenshot1 2 I just need to get the start and end time from a timepickerdialog and set a TextView by using start and end time values but I have the same start and end time values because I can not get the value from timepicker for start time and when I click done, It assigns both the last value of timepicker which makes sense. By the way, If there is a bad code implementation, I am really sorry. Thank you for any help.
private int openingHour = 0;
private int openingMinute = 0;
private int closingHour = 0;
private int closingMinute = 0;
private void setWorkingHoursTextView() {
// TODO Auto-generated method stub
Calendar mCurrentTime = Calendar.getInstance();
int initialHour = mCurrentTime.get(Calendar.HOUR_OF_DAY);
int initialMinute = mCurrentTime.get(Calendar.MINUTE);
TimePickerDialog mTimePickerDialog = new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
openingHour = timePicker.getHour();
openingMinute = timePicker.getMinute();
if (openingHour != 0) {
closingHour = timePicker.getHour();
closingMinute = timePicker.getMinute();
}
}
else {
if (openingHour != 0) {
closingHour = timePicker.getCurrentHour();
closingMinute = timePicker.getCurrentMinute();
}
else {
openingHour = timePicker.getCurrentHour();
openingMinute = timePicker.getCurrentMinute();
}
}
workingHoursTextView.setText(
openingHour + ":" + openingMinute + "-" + closingHour + ":" + closingMinute);
}
}, initialHour, initialMinute, true);//Yes 24 hour time
mTimePickerDialog.setMessage("Opening Time");
mTimePickerDialog.show();
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEUTRAL).setVisibility(View.VISIBLE);
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEUTRAL).setText("Cancel");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEUTRAL).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mTimePickerDialog.dismiss();
}
});
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setText("Next");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setTag("Next");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mTimePickerDialog.updateTime(initialHour, initialMinute);
if (mTimePickerDialog
.getButton(DialogInterface.BUTTON_NEGATIVE).getTag().equals("Next")) { //Next
mTimePickerDialog.setMessage("Closing Time");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setText("Back");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setTag("Back");
}
else if (mTimePickerDialog
.getButton(DialogInterface.BUTTON_NEGATIVE).getTag().equals("Back")){ //Back
mTimePickerDialog.setMessage("Opening Time");
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setText("Next");
if (openingHour != 0 && openingMinute != 0) {
mTimePickerDialog.updateTime(initialHour, initialMinute);
}
mTimePickerDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setTag("Next");
}
else ;
}
});
mTimePickerDialog.getButton(DialogInterface.BUTTON_POSITIVE).setText("Done");

On TimePickerDialog, there is variable selectedHour and selectedMinute. You can use that to retrieve the value of what you select. The code should be like this
TimePickerDialog mTimePickerDialog = new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
if (openingHour != 0) {
closingHour = selectedHour;
closingMinute = selectedMinute;
}
else {
openingHour = selectedHour;
openingMinute = selectedMinute;
}
workingHoursTextView.setText(
openingHour + ":" + openingMinute + "-" + closingHour + ":" + closingMinute);
}
}, initialHour, initialMinute, true);//Yes 24 hour time

store two time picker values in single fields

My app lets user enter two times to set device in silent mode in a specific time for an event. What I have done so far?
take start and end time input from user
activate silent mode and restore sound mode at the given time by the user.
What I need?
store start and end time values in sqlite database but in a single Time field.
For example:
ID Event Name Time
1 study time 2:00 PM-4:00 PM

here is method

How to restrict user to set date based on other date from date picker in android

I have 2 date-picker in one activity. What i want to do is when user try to select date from second date-picker then that date should greater than first date-picker's date otherwise it should show alert dialog.
So below is my code.
public class Assignment_Create extends Activity implements OnClickListener {
DataManipulator dataManipulator;
static final int DIALOG_ID = 1;
ImageView imageViewDateAssign, imageViewDueDate, imageViewSubmit;
TextView textViewDtAssign, textViewDueDt;
EditText editTextTitle, editTextDesc;
static final int DATE_DIALOG_ID = 0;
int cDay, cMonth, cYear;
private TextView activeDateDisplay;
private Calendar activeDate;
// Update database
String updateId;
public boolean isEdit;
#Override
public void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.assignment_create);
imageViewDateAssign = (ImageView) findViewById(R.id.dateassign);
imageViewDueDate = (ImageView) findViewById(R.id.duedate);
imageViewSubmit = (ImageView) findViewById(R.id.submit);
textViewDtAssign = (TextView) findViewById(R.id.textViewDateAssign);
textViewDueDt = (TextView) findViewById(R.id.textViewDueDate);
editTextTitle = (EditText) findViewById(R.id.title);
editTextDesc = (EditText) findViewById(R.id.description);
isEdit = getIntent().getExtras().getBoolean("isEdit");
updateId = getIntent().getExtras().getString("idNo");
if (isEdit) {
editTextTitle.setText(getIntent().getExtras().getString(
"AsmntTitle"));
editTextDesc
.setText(getIntent().getExtras().getString("AsmntDesc"));
}
Code.AssignDate = Calendar.getInstance();
Code.DueDate = Calendar.getInstance();
imageViewDateAssign.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
showDateDialog(textViewDtAssign, Code.AssignDate);
}
});
imageViewDueDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
showDateDialog(textViewDueDt, Code.DueDate);
}
});
imageViewSubmit.setOnClickListener(this);
updateDisplay(textViewDtAssign, Code.AssignDate);
updateDisplay(textViewDueDt, Code.DueDate);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit:
Code.title = editTextTitle.getText().toString().trim();
Code.description = editTextDesc.getText().toString().trim();
Code.diff = Code.DueDate.getTimeInMillis()
- Code.AssignDate.getTimeInMillis();
Code.days = Code.diff / (24 * 60 * 60 * 1000);
Code.strDays = String.valueOf(Code.days);
Date assignDate = new Date(Code.AssignDate.getTimeInMillis());
Date dueDate = new Date(Code.DueDate.getTimeInMillis());
if (dueDate.before(assignDate) || dueDate.equals(assignDate)) {

});
myDialogBattery.show();
}
if (isEdit) {

this.dataManipulator.update(updateId);
this.dataManipulator.close();
} else {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.insert(Code.title, Code.description,
Code.strDays);
this.dataManipulator.close();
}
Toast.makeText(getApplicationContext(),
"Details are saved successfully", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(),
"Assignment Created Succesfully", Toast.LENGTH_LONG).show();
Assignment_Create.this.finish();
break;
}
}
private void updateDisplay(TextView dateDisplay, Calendar date) {

So what i am doing wrong, can anyone help me please. Thanks in advance.

Just compare getTimeInMillis of Calendar
Calendar mCalendarFirst = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_frist_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_frist_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_frist_datepicker);
Calendar mCalendarSecond = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_second_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_seconf_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_second_datepicker);
if(mCalendarSecond.getTimeInMillis() <= mCalendarFirst.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Update:
For your situation use below:
if(Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Try Below code:
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit:
Code.title = editTextTitle.getText().toString().trim();
Code.description = editTextDesc.getText().toString().trim();
Code.diff = Code.DueDate.getTimeInMillis()
- Code.AssignDate.getTimeInMillis();
Code.days = Code.diff / (24 * 60 * 60 * 1000);
Code.strDays = String.valueOf(Code.days);
Date assignDate = new Date(Code.AssignDate.getTimeInMillis());
Date dueDate = new Date(Code.DueDate.getTimeInMillis());
if (Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis()){
AlertDialog.Builder myDialogBattery = new AlertDialog.Builder(
Assignment_Create.this);
myDialogBattery.setTitle("How to use Less Battery");
myDialogBattery.setMessage("hahahahahaha");
myDialogBattery.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
myDialogBattery.show();
}else
{
if (isEdit) {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.update(updateId);
this.dataManipulator.close();
} else {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.insert(Code.title, Code.description,
Code.strDays);
this.dataManipulator.close();
}
Toast.makeText(getApplicationContext(),
"Details are saved successfully", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(),
"Assignment Created Succesfully", Toast.LENGTH_LONG).show();
Assignment_Create.this.finish();
}
break;
}
}

try following code. Here firstDate and secondDate are Date object
if (firstDate.after(secondDate)) { OR //secondDate.before(firstDate)
//display alert here
} else {
}
