I'm trying to get simple DatePickerDialog working code bellow as can be found in Android documentation



import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;

import java.util.Calendar;

public class DatePickerDialogExample extends Activity {
    private TextView mDateDisplay;
    private Button mPickDate;
    private int mYear;
    private int mMonth;
    private int mDay;

    static final int DATE_DIALOG_ID = 0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mDateDisplay = (TextView) findViewById(R.id.dateDisplay);
        mPickDate = (Button) findViewById(R.id.pickDate);

        mPickDate.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                showDialog(DATE_DIALOG_ID);
            }
        });

        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);

        updateDisplay();
    }

    private void updateDisplay() {
        mDateDisplay.setText(
                new StringBuilder()
                        .append(mMonth + 1).append("-")
                        .append(mDay).append("-")
                        .append(mYear).append(" "));
    }

    private DatePickerDialog.OnDateSetListener mDateSetListener =
            new DatePickerDialog.OnDateSetListener() {

                public void onDateSet(DatePicker view, int year,
                                      int monthOfYear, int dayOfMonth) {
                    mYear = year;
                    mMonth = monthOfYear;
                    mDay = dayOfMonth;
                    updateDisplay();
                }
            };

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
            case DATE_DIALOG_ID:
                return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
                        mDay);
        }
        return null;
    }

}

However I'm running into weird error

In XML add a TextView and a Button

<TextView
    android:id="@+id/searchText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />

<Button
    android:id="@+id/search"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Search" />

Add following code in java file

public class DatePickerDialogExample extends Activity {

    TextView txtDate;
    private int mYear, mMonth, mDay, mHour, mMinute;

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


        txtDate = (TextView) findViewById(R.id.searchText);
        Button search = (Button) findViewById(R.id.search);
        search.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // Process to get Current Date
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);

            // Launch Date Picker Dialog
            DatePickerDialog dpd = new DatePickerDialog(PrayTimeActivity.this,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int monthOfYear, int dayOfMonth) {
                            // Display Selected date in textbox
                            txtDate.setText(dayOfMonth + "-"
                                    + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
                dpd.show();
            }
        });


    }

}
