我想在DatePickerDialog中禁用今天日期之前的日期。我是android的新手请建议我怎么做。这是我为DatePickerDialog编写的代码。
<TextView
android:id="@+id/tv_arrival"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:text="@string/arrivaldate"/>
<Button
android:id="@+id/btn_arrival"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Set"/>
Button btn_arrival = (Button) findViewById(R.id.btn_arrival);
txt_arrival = (TextView) findViewById(R.id.tv_arrival);
myCalendar = Calendar.getInstance();
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
btn_arrival.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
new DatePickerDialog(MainActivity.this,date , myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
}
});
private void updateLabel() {
String myFormat = "dd.MM.yyyy"; //In which you need put here.
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
txt_arrival.setText("Arrival Date on:" + sdf.format(myCalendar.getTime()));
}
请告诉我该怎么做。

您可以使用此行代码
datePicker.setMinDate(System.currentTimeMillis() - 1000);
你可以像这样使用它。我测试了它,它的工作原理
import android.app.DatePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button mButton = (Button)findViewById(R.id.m_button);
mButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog mDate = new DatePickerDialog(MainActivity.this, date, 2016, 2, 24);
mDate.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
mDate.show();
}
});
}
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
view.setMinDate(System.currentTimeMillis() - 1000);
}
};
}

start_date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR); // current year
int mMonth = c.get(Calendar.MONTH); // current month
int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
// date picker dialog
datePickerDialog1 = new DatePickerDialog(getActivity(),
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// set day of month , month and year value in the edit text
dept_dayofWeek.setText(dayOfMonth + "/" + (monthOfYear + 1) + "/" + year);
}
}, mYear, mMonth, mDay);
datePickerDialog1.getDatePicker().setMinDate(System.currentTimeMillis() - 1000); //disable previous dates
datePickerDialog1.show();
}
});

我测试了代码并且它可以正常工作
final Calendar calendarEndDate = Calendar.getInstance();
YearEndDate = calendarEndDate.get(Calendar.YEAR);
MonthEndDate = calendarEndDate.get(Calendar.MONTH);
DayEndDate = calendarEndDate.get(Calendar.DAY_OF_MONTH);
updateEndDisplay();
endDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
DatePickerDialog endDate = new DatePickerDialog(AttendandItemRequest.this,
endDateSetListener,
YearEndDate, MonthEndDate, DayEndDate);
endDate.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
endDate.show();
}
});
