Here is a custom TimePickerDialog with seconds.

MainActivity.java

import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.NumberPicker;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
        final TextView timeTV = findViewById(R.id.time_text_view);
        timeTV.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                View view = View.inflate(MainActivity.this, R.layout.time_dialog, null);
                final NumberPicker numberPickerHour = view.findViewById(R.id.numpicker_hours);
                numberPickerHour.setMaxValue(23);
                numberPickerHour.setValue(sharedPreferences.getInt("Hours", 0));
                final NumberPicker numberPickerMinutes = view.findViewById(R.id.numpicker_minutes);
                numberPickerMinutes.setMaxValue(59);
                numberPickerMinutes.setValue(sharedPreferences.getInt("Minutes", 0));
                final NumberPicker numberPickerSeconds = view.findViewById(R.id.numpicker_seconds);
                numberPickerSeconds.setMaxValue(59);
                numberPickerSeconds.setValue(sharedPreferences.getInt("Seconds", 0));
                Button cancel = view.findViewById(R.id.cancel);
                Button ok = view.findViewById(R.id.ok);
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setView(view);
                final AlertDialog alertDialog = builder.create();
                cancel.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        alertDialog.dismiss();
                    }
                });
                ok.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        timeTV.setText(numberPickerHour.getValue() + ":" + numberPickerMinutes.getValue() + ":" + numberPickerSeconds.getValue());
//                        timeTV.setText(String.format("%1$d:%2$02d:%3$02d", numberPickerHour.getValue(), numberPickerMinutes.getValue(), numberPickerSeconds.getValue()));
                        SharedPreferences.Editor editor = sharedPreferences.edit();
                        editor.putInt("Hours", numberPickerHour.getValue());
                        editor.putInt("Minutes", numberPickerMinutes.getValue());
                        editor.putInt("Seconds", numberPickerSeconds.getValue());
                        editor.apply();
                        alertDialog.dismiss();
                    }
                });
                alertDialog.show();
            }
        });
    }
