I have resolved my issue using this library and here is my complete code which may help someone in the future.

My complete code is in below.

public class MainActivity extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener {

    private TextView timeTextView;
    private TimePickerDialog timePickerDialog;
    private Button timeButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Find our View instances
        timeTextView = findViewById(R.id.time_textview);
        timeButton = findViewById(R.id.time_button);

        // Show a timepicker when the timeButton is clicked
        timeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Calendar now = Calendar.getInstance();

                timePickerDialog = TimePickerDialog.newInstance(
                        MainActivity.this,
                        now.get(Calendar.HOUR_OF_DAY),
                        now.get(Calendar.MINUTE),
                        false
                );

                timePickerDialog.setThemeDark(false);
                timePickerDialog.setTitle("TimePicker Title");
                timePickerDialog.setTimeInterval(1, 30, 60);                            
                timePickerDialog.setAccentColor(Color.parseColor("#9C27B0"));

                timePickerDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
                    @Override
                    public void onCancel(DialogInterface dialogInterface) 
                        Log.d("TimePicker", "Dialog was cancelled");
                    }
                });
                timePickerDialog.show(getFragmentManager(), "Timepickerdialog");
            }
        });
    }

    @Override
    public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {
        updateEndTime(hourOfDay,minute);
    }

    private void updateEndTime(int hours, int mins) {
        String timeSet = "";
        if (hours > 12) {
            hours -= 12;
            timeSet = "PM";
        } else if (hours == 0) {
            hours += 12;
            timeSet = "AM";
        } else if (hours == 12) {
            timeSet = "PM";
        } else {
            timeSet = "AM";
        }

        // Append in a StringBuilder
        String aTime = new StringBuilder().append(pad(hours)).append(':')
                .append(pad(mins)).append(" ").append(timeSet).toString();

        timeTextView.setText(aTime);
    }

    private static String pad(int c) {
        if (c >= 10)
            return String.valueOf(c);
        else
            return "0" + String.valueOf(c);
    }

    @Override
    public void onResume() {
        super.onResume();
        TimePickerDialog tpd = (TimePickerDialog) getFragmentManager().findFragmentByTag("Timepickerdialog");
        if (tpd != null) tpd.setOnTimeSetListener(this);
    }
}

My desire output is like this:
