How do you check if the time (hour) is equal to?

Basically I created a text (TextView) where the current time of the device is shown.
i want to put the time in a variable. And then check if the time is equal to (a specific time eg 14:15) when you click on the text a music starts singing.
CODE ⬇️
package com.example.simplecalculatorbyvalentinlearningapp;
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class SeccondScreen extends AppCompatActivity {
TextView h;
TextView d;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_seccond_screen);
//Sound
final MediaPlayer betaaudio = MediaPlayer.create (this, R.raw.betaaudio);
h = (TextView) findViewById(R.id.hour);
d = (TextView) findViewById(R.id.date);
//hour BETA CODE
Calendar calendar = Calendar.getInstance();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm");
String dateTime = SimpleDateFormat.getTimeInstance().format(calendar.getTime());
h.setText(dateTime);
//date BETA CODE
calendar = Calendar.getInstance();
simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss a");
dateTime = SimpleDateFormat.getDateInstance().format(calendar.getTime());
d.setText(dateTime);
//start sound
String vhour = ;
if(vhour == "trad" ) {
h.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
betaaudio.start();
}
});
}
}
}
This is all the code.
I managed to do almost everything but I am stuck to the vhour variable to put the current time inside and then check with (if) if the time is equal to 14:15 for example, to make the code work inside the if, how can i do this?

you want to substring current hour from datatime variable
like this:
String dateTime = SimpleDateFormat.getDateInstance().format(calendar.getTime());
String currentTime = dateTime.substring(10,16);
and you want put check statement inside onClickListener not out side it :
h.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (currentTile.equals("14:43") {
betaaudio.start();
}
}
});

package com.example.simplecalculatorbyvalentinlearningapp;
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class SeccondScreen extends AppCompatActivity {
TextView h;
TextView d;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_seccond_screen);
//Sound
final MediaPlayer betaaudio = MediaPlayer.create (this, R.raw.betaaudio);
h = (TextView) findViewById(R.id.hour);
d = (TextView) findViewById(R.id.date);
//hour BETA CODE
Calendar calendar = Calendar.getInstance();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm");
String dateTime = SimpleDateFormat.getTimeInstance().format(calendar.getTime());
h.setText(dateTime);
//date BETA CODE
calendar = Calendar.getInstance();
simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss a");
dateTime = SimpleDateFormat.getDateInstance().format(calendar.getTime());
d.setText(dateTime);
//start sound
String currentTime = dateTime.substring(10,16);
h.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (currentTime.equals("14:43")) {
betaaudio.start();
}
}
});
}
}

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.

Change colour of an item view in recycler view after comparison with its textview data

I have a RecyclerView with 'n' number of ItemViews in it. These ItemViews contain Textviews with data with are updated through Firestore.
Now I need to compare one of the value0(getexpirydate) in the Textviews with another value1(Current date). Then if value1 > value0, then change the colour of that specific Itemview to RED. else GREEN.

if (d1.after(date1)){
holder.contractname.setTextColor(Color.GREEN);
}
} catch (ParseException e) {
e.printStackTrace();
}

#Override
public void onBindViewHolder(#NonNull ContractsAdapter.ContractViewHolder holder, int position) {
Contracts contract = contractsList.get(position);
if (contract.getCurrentDate() > contract.getDateofexpiry()) {
holder.dateofexpiry.setTextColor(Color.RED);
}
holder.dateofexpiry.setText(contract.getDateofexpiry());
}

In registration activity I've added a comment by only that code my app show the error message. If I remove the radiobutton code and the getString String. It works properly and then it doesn't show app stopped working message.
So why I'm not able to pass the value of the radiobutton string from one activity to another.

Try this may be your radiobutton id returns -1 if no values are selected in radio group.
int chk_gender = rg_gender.getCheckedRadioButtonId();
if (chk_gender != -1) {
Gender = ((RadioButton)findViewById(chk_gender)).getText().toString();
}
else
{
Gender = "";
}
EDITED
rg_gender.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId != -1) {
Gender = ((RadioButton)findViewById(checkedId)).getText().toString();
}
else
{
Gender = "";
}
}
});

In your xml layout ,did you checked TRUE any radio button ?
You should get the selected radio button value on click of submit button.It will update your setGender string with most recent value.
for your app crash , Please post your logcat error while app crash.

Create a TimePickerDialog using the FragmentDialog?

Now I want to create a TimePickerDialog .

public class DialogFragmentTimePicker extends DialogFragment implements OnTimeSetListener {
public static final String ARG_HOUR = "hour";
public static final String ARG_MINUTE = "minute";
private OnTimeSetListener mListener;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current time as the default values for the picker
int hour, minute;
if (getArguments() != null) {
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);
}
}
}
