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.

Not display current time for android timePicker dialog

I have a timeIn editText in my app. When it is clicked, it will pop up TimePicker dialog.
timeIn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) { //shows timePick
isEdited=true;
Fragment fragDialog = getSupportFragmentManager().findFragmentByTag("TimePicker");
if (fragDialog == null) { // Fragment not added
tp.setFlag(TimePick.FLAG_START_DATE);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
tp.show(ft, "TimePicker");
} else {
// already active
}
}
});
public static class TimePick extends android.support.v4.app.DialogFragment implements TimePickerDialog.OnTimeSetListener {
public static final int FLAG_START_DATE = 00;
public static final int FLAG_END_DATE = 01;
private int flag = 00;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
return new TimePickerDialog(getActivity(), this, hour, minute, DateFormat.is24HourFormat(getActivity()));
}
public void setFlag(int i) {
flag = i;
}
#Override
public void onTimeSet(TimePicker view, int hourofDay, int minute) {
if (flag == FLAG_START_DATE) {
timeIn.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
TimeIn = timeIn.getText().toString();
}
if (flag == FLAG_END_DATE) {
timeOut.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
TimeOut = timeOut.getText().toString();
}
}
}
The time selected can be setText in timeIn. But when I click the timeIn editText again, the timePicker dialog popup with the current time . Is it possible to make it display the selected time instead of current time ? If it is first time click, then only show current time.

Isn't that what you are doing here
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
return new TimePickerDialog(getActivity(), this, hour, minute, DateFormat.is24HourFormat(getActivity()));
You are passing the current time to the dialog, that's why its showing the current time.
Solution:
Save the selected time and pass that to the class while creating the dialog and use that time in this code. If you don't have any selected time then use the current time. A little if-else block and some variables will do the trick.
Define these variable in outer class.
public static int inHour = -1;
public static int inMin = -1;
public static int outHour = -1;
public static int outMin = -1;
update onTimeSet method like this
if (flag == FLAG_START_DATE) {
inHour = hourofDay;
inMin = minute;
timeIn.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
TimeIn = timeIn.getText().toString();
}
else if (flag == FLAG_END_DATE) {
outHour = hourofDay;
outMin = minute;
timeOut.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
TimeOut = timeOut.getText().toString();
}
Replace your current code in onCreateDialog with
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int min = c.get(Calendar.MINUTE);
if((flag == FLAG_START_DATE) && inHour != -1 && inMin != -1)
{
hour = inHour;
min = inMin;
}
else if((flag == FLAG_END_DATE) && outHour != -1 && outMin != -1)
{
hour = outHour;
min = outMin;
}
return new TimePickerDialog(getActivity(), this, hour, min, DateFormat.is24HourFormat(getActivity()));

Limit Time Range in Time Picker

How to control TimePicker, I just want to show time range in time picker from 08:00 am to 02:00 pm (except from 08:00 am to 02:00 pm hide all)
I have written complete code to show TimePicker, and customized time as well.
Here is my code:
case DIALOG_TIME:
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(this, lisTime, hour, minute,
DateFormat.is24HourFormat(MainActivity.this));
TimePickerDialog.OnTimeSetListener lisTime = new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
String meridiem = "";
nim = minute;
Calendar datetime = Calendar.getInstance();
datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
datetime.set(Calendar.MINUTE, minute);
if (datetime.get(Calendar.AM_PM) == Calendar.AM)
meridiem = "AM";
else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
meridiem = "PM";
hour = (datetime.get(Calendar.HOUR) == 0) ?"12":String.valueOf(datetime.get(Calendar.HOUR));
String time = pad(Integer.parseInt(hour)) + ":" + pad(minute) + " " + meridiem;
editTime.setText(time);
}
};
private String pad(int value){
if(value<10){
return "0"+value;
}
return ""+value;
}

As in this answer: https://stackoverflow.com/a/20396673/4130107
You can create your custom TimePickerDialog and overwrite the onAttachedToWindow(); but instead limit the hour range:
private final boolean mIs24HourView;
public CustomTimePickerDialog(Context context, OnTimeSetListener callBack,
int hourOfDay, int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
mIs24HourView = is24HourView;
}
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.android.internal.R$id");
Field timePickerField = classForid.getField("timePicker");
this.timePicker = (TimePicker) findViewById(timePickerField
.getInt(null));
Field field = classForid.getField("hour");
final NumberPicker mHourSpinner = (NumberPicker) timePicker
.findViewById(field.getInt(null));
if (mIs24HourView) {
mHourSpinner.setMinValue(2);
mHourSpinner.setMaxValue(20);
}else {
Field amPm = classForid.getField("amPm");
mHourSpinner.setMinValue(2);
final NumberPicker amPm = (NumberPicker) timePicker
.findViewById(amPm.getInt(null));
amPm.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
#Override
public void onValueChange(NumberPicker np1, int oldVal, int newVal) {
if (newVal == 0) { // case AM
mHourSpinner.setMinValue(2);
mHourSpinner.setMaxValue(12);
} else { // case PM
mHourSpinner.setMinValue(1);
mHourSpinner.setMaxValue(8);
}
}
});
}
} catch (Exception e) {
e.printStackTrace();
}
}
EDIT: now working for AM/PM too

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 {

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 {
}
