Calender.getInstance() gives error in Android Studio

Question

I'm trying to pop-open a DatePicker dialogue box when my EditText is clicked. The problem is, when I try to instantiate my Calender object with Calender.getInstance() the creepy-red-underline appears below getInstance().

Calender myCalender = Calender.getInstance();

Hover over it and it says

Call requires API level 24(current minimum is 15).

Obviously I expect my app to run on devices at the minimum API level 15. Please help me with this, I'm new to Android. Thank you.

I tried to follow this method to add a DatePicker to my EditText

Which Calendar do you use? – Pentheus

The Internationalization guide explains what ICU is and how to use it for <= API 23 (6.0) vs API 24 (7.0) onwards – Katheleenkatherin

Answer 1

You have the wrong import statement for Calendar. It needs to be java.util.Calendar. My guess is that you have an import for android.icu.util.Calendar.

This code will help  you to solve your problem..
It will pop-open a DatePicker dialogue box when onClick EditText box:

1) MainActivity.java

import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.icu.text.DateFormat;
import android.icu.util.Calendar; 
import android.support.v7.app.AlertDialog;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity
{
    EditText editText1;
    private int nYear,nMonth,nDay,sYear,sMonth,sDay;
    static final int DATE_ID = 0;
    Calendar c = Calendar.getInstance();

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

        editText1 = (EditText) findViewById(R.id.editText1);
        sYear = c.get(Calendar.YEAR);
        sMonth = c.get(Calendar.MONTH);
        sDay = c.get(Calendar.DAY_OF_MONTH);
        //editText
        editText1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showDialog(DATE_ID);
            }
        });

    /***************calender code*****************/
    private void calender_fetch()
    {
        editText1.setText((nMonth+1)+"/"+nDay+"/"+nYear+"");
    }

    private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
        {
            nYear = year;
            nMonth = monthOfYear;
            nDay = dayOfMonth;
            calender_fetch();
        }
    };
    @Override
    protected Dialog onCreateDialog(int id)
    {
        switch (id)
        {
            case DATE_ID:
                return new DatePickerDialog(this, mDateSetListener, sYear, sMonth, sDay);
        }
        return null;
    }
    /*************************calender close*********************************/

Answer 3

use: import java.util.Calendar;

This is the package we need to use to get Calendar on the dialog box, instead of,

instead: import android.icu.util.Calendar;

this works fine.
