Answer 1

当您可以自己完成时，无需添加库.....我在这里使用了editText，你可以做任何事情，一个图像，一个按钮，文本视图

主活动

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();
}
});
}
}
