带有edittext中预选值的DatePicker对话框

Question

<EditText
            android:id="@+id/dob"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:inputType="date"
            android:hint="Date Of Birth"
            android:textSize="12sp"
         android:drawableRight="@drawable/ic_perm_contact_calendar_black_24dp"
            android:drawableTint="@android:color/holo_orange_light"/>

Java代码：

dob.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                final Calendar myCalendar = Calendar.getInstance();
                DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        // TODO Auto-generated method stub
                        myCalendar.set(Calendar.YEAR, year);
                        myCalendar.set(Calendar.MONTH, monthOfYear);
                        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                        String myFormat = "dd-MMM-yyyy"; // your format
                        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());

                        dob.setText(sdf.format(myCalendar.getTime()));
                    }

                };
                new DatePickerDialog(PersonalDetailsFormActivity.this, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();

            }
        });

我已经通过许多在线链接，但都显示如何在edittext中设置日期，但我想要的是相反的。edittext中有一个值，datepicker对话框将打开，该日期将作为预选值。

您可以使用参数调用datePickerDialog,

DatePickerDialog dialog = new DatePickerDialog(this, mDateSetListener, year, month, day);

这里的月份、日期和年份是整数。

找到下面的示例代码：

public class MainActivity extends AppCompatActivity {

private EditText chooseDate;
private DatePickerDialog.OnDateSetListener mDateSetListener;
final Calendar myCalendar = Calendar.getInstance();
private Date date;
SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    chooseDate = (EditText) findViewById(R.id.choose_date);

    chooseDate.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            mDateSetListener = new DatePickerDialog.OnDateSetListener() {

                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    // TODO Auto-generated method stub

                    myCalendar.set(Calendar.YEAR, year);
                    myCalendar.set(Calendar.MONTH, monthOfYear);
                    myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                    chooseDate.setText(formatter.format(myCalendar.getTime()));
                }

            };
            try {
                if (chooseDate.getText().toString().isEmpty()) {
                    date = new Date();

                } else {
                    date = formatter.parse(chooseDate.getText().toString());
                }
                Calendar calendar = new GregorianCalendar();
                calendar.setTime(date);
                int year = calendar.get(Calendar.YEAR);
                int month = calendar.get(Calendar.MONTH);
                int day = calendar.get(Calendar.DAY_OF_MONTH);
                new DatePickerDialog(MainActivity.this, mDateSetListener, year, month, day).show();
            } catch (ParseException e) {
                Log.d(TAG, "ParseException" + e);
            }
        }
    });
}
