Time picker stops working after date picker is added - java

I'm building an app that displays a date picker and a time picker on the click of two seperate buttons. I first added in the time picker and it was all working fine, I then proceeded to add the date picker which also works fine. The problem here being that when I added in the date picker, it casused the time picker to stop working. I know they both work and i'm 90% sure it is because of the structure of my code but being that i'm completely new to android and java development I can't work out where i'm going wrong. Any help would be appreciated.
Thanks

Somebody please help me I am Newbie to this.

This is another method of sending data from Adapter to Activity.
Follow these steps carefully:
Create an interface with a method
public interface InterfaceTax {
public void getTaxMoney(int amount);
}
the parameters of the method should contain the data you want to send back to the activity.
Create a variable for that interface in the Adapter and add the interface to the constructor of the Adapter.
private InterfaceTax interfaceT;
public ChannelAdapter(/* other parameters */, InterfaceTax interface) {
interfaceT = interface;
}
Then in onBindViewHolder (or wherever your data is) call the method of the interface and send the data
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int i) {
money = String.valueOf(channel_tMoney.get(i));
interface.getTaxMoney(money);
}
Then in your activity implement the interface and override the method to receive data
public class UserDetailsActivity extends AppCompatActivity implements InterfaceTax {}
#Override
public void getTaxMonney(int data) {
// receive data here
}
In your AddChannel method, replace this line
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney);
with this
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney, this);
This will automatically send the data from the adapter to the activity and you can receive it in the method overridden in the activity.

Why won't my program open? The code says there are no errors, but these two classes won't open together

These two classes send methods and variables back and forth to each other and my code says there's no errors, but the program won't open and I can't figure out why

call code like this after you call setContentView:
Activity 1:
TextView mText = (TextView) findViewById(R.id.calendarView);
Activity 2:
private TextView name = (TextView) findViewById(R.id.name);
you did that wrong in both Activitys. You call findViewById in the member section of your Activitys and at this point the Activity dont know anything about the layout file.
That must leads to a NullpointerException.

Use different id of DATE_DIALOG_ID and TIME_DIALOG_ID;

I think you need to give different id's for DATE_DIALOG_ID and TIME_DIALOG_ID.
check these fields once.
static final int DATE_DIALOG_ID = 0;
static final int TIME_DIALOG_ID = 1;

Create a TimePickerDialog using the FragmentDialog?

I want to create a TimePickerDialog using FragmentDialog and exchange data between my fragment and the TimePickerDialog . I already created a DatePickerDialog but I don't know how to create a TimePickerDialog . I want that when the user click the button in my fragment TimePickerDialog appear .
This is how I create The DatePickerDialog :
import java.util.Calendar; import java.util.Date; import

public static DatePickerFragment newInstance(Date date) {
Bundle args = new Bundle();
args.putSerializable(EXTRA_DATE, date);
DatePickerFragment fragment = new DatePickerFragment();
fragment.setArguments(args);
return fragment;
}
private void sendResult(int resultCode) {
if (getTargetFragment() == null)
return;
Intent i = new Intent();
i.putExtra(EXTRA_DATE, mDate);
getTargetFragment()
.onActivityResult(getTargetRequestCode(), resultCode, i);
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
mDate = (Date)getArguments().getSerializable(EXTRA_DATE);
Calendar calendar = Calendar.getInstance();
calendar.setTime(mDate);
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);
View v = getActivity().getLayoutInflater()
.inflate(R.layout.dialog_date, null);
DatePicker datePicker = (DatePicker)v.findViewById(R.id.dialog_date_datePicker);
datePicker.init(year, month, day, new OnDateChangedListener() {
public void onDateChanged(DatePicker view, int year, int month, int day) {
mDate = new GregorianCalendar(year, month, day).getTime();
// update argument to preserve selected value on rotation
getArguments().putSerializable(EXTRA_DATE, mDate);
}
});
return new AlertDialog.Builder(getActivity())
.setView(v)
.setTitle(R.string.date_picker_title)
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {

})
.create();
} }

Now I want to create a TimePickerDialog .

public class DialogFragmentTimePicker extends DialogFragment implements OnTimeSetListener {

#Override

hour = getArguments().getInt(ARG_HOUR);
minute = getArguments().getInt(ARG_MINUTE);
} else {
final Calendar c = Calendar.getInstance();
hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE);
}
// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), this, hour, minute, DateFormat.is24HourFormat(getActivity()));
}
public void setOnTimeSetListener(OnTimeSetListener listener) {
mListener = listener;
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
if (mListener != null) {
mListener.onTimeSet(view, hourOfDay, minute);
}
}
}

Passing items to onPause() method

I know this is a basic question, but I'm pretty new to all of this. In the code below, I have this onPause method:
public void onPause(){
super.onPause();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(input.getWindowToken(), 0);
}
The input part of input.getWindowToken() doesn't work. I'm guessing that it's because it's not defined/instantiated in the same scope? I think I'm using the right terminology. I'm not even positive that I should be trying to use an EditText object right here either, but it seems whatever I try to do isn't working.
How do I pass something to my onPause() method, or any other method for that matter? Here's all of my code:

Thanks for the help!

Make it a variable in your class.
public class NewWorkout extends Activity {
private EditText input
...
public void nameOfWorkout(View view){
// Set an EditText view to get user input
input = new EditText(this);
...
}
public void onPause() {
if (input != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(input.getWindowToken(), 0);
}
super.onPause();
}
...
}

Well, you can use this as an alternative.
public void onPause()
{
super.onPause();
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
