Answer 1

There is no need to add library when you can do it yourself..... I used an editText here, you can do anything, an image, a button, textview

MainActivity

public class MainActivity extends AppCompatActivity {


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

        final EditText editText = (EditText) findViewById(R.id.editText);

        editText.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                //To show current date in the datepicker
                Calendar mcurrentDate=Calendar.getInstance();
                int year = mcurrentDate.get(Calendar.YEAR);
                int month = mcurrentDate.get(Calendar.MONTH);
                int day = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog mDatePicker=new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
                    public void onDateSet(DatePicker datepicker, int selectedYear, int selectedMonth, int selectedDay) {
                        // TODO Auto-generated method stub
                    /*      Your code   to get date and time    */
                        Log.e("Date Selected", "Month: " + selectedMonth + " Day: " + selectedDay + " Year: " + selectedYear);
                        editText.setText(selectedMonth + "/" + selectedDay + "/" + selectedYear);
                    }
                },year, month, day);
                mDatePicker.setTitle("Select date");
                mDatePicker.show();
            }
        });

    }
}

XML

<EditText

</android.support.constraint.ConstraintLayout>
