我想显示日期选择器弹出窗口。我找到了一些例子，但我没有得到正确的。我有一个edittext，我希望当我点击edittext时，datepicker对话框应该弹出，设置日期后，日期应该显示在edittext在dd/mm/yyyy格式。请为我提供示例代码或良好的链接。

在XML文件中试试这个:
<EditText
android:id="@+id/Birthday"
custom:font="@string/font_avenir_book"
android:clickable="false"
android:cursorVisible="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:hint="@string/birthday"/>
在Java文件中是这样的:
public class MainActivity extends AppCompatActivity {
final Calendar myCalendar= Calendar.getInstance();
EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText=(EditText) findViewById(R.id.BirthDate);
DatePickerDialog.OnDateSetListener date =new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH,month);
myCalendar.set(Calendar.DAY_OF_MONTH,day);
updateLabel();
}
};
editText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new DatePickerDialog(MainActivity.this,date,myCalendar.get(Calendar.YEAR),myCalendar.get(Calendar.MONTH),myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
});
}
private void updateLabel(){
String myFormat="MM/dd/yy";
SimpleDateFormat dateFormat=new SimpleDateFormat(myFormat, Locale.US);
editText.setText(dateFormat.format(myCalendar.getTime()));
}
}
在EditText的xml文件中添加android:focusable="false"以允许单个触摸。
其他回答
editText。setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
final DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
new DatePickerDialog.OnDateSetListener() {
String fmonth, fDate;
int month;
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
try {
if (monthOfYear < 10 && dayOfMonth < 10) {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
fDate = "0" + dayOfMonth;
String paddedMonth = String.format("%02d", month);
editText.setText(fDate + "/" + paddedMonth + "/" + year);
} else {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
String paddedMonth = String.format("%02d", month);
editText.setText(dayOfMonth + "/" + paddedMonth + "/" + year);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
datePickerDialog.show();
}
});
我认为最好重写EditText类…
public class EditTextDP extends android.support.v7.widget.AppCompatEditText implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
public EditTextDP(Context context) {
super(context);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs) {
super(context, attrs);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setOnClickListener(this);
setFocusable(false);
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
setText(new StringBuilder().append(dayOfMonth).append("/").append(monthOfYear + 1).append("/").append(year));
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(getContext(), this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
}
然后在XML中使用它…
<*.*.*.EditTextDP
android:id="@+id/c1_dob_hm"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/round_edittext_white"
android:ems="10"
android:padding="8dp">
</*.*.*.EditTextDP>
使用数据绑定:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:onClick="@{() -> viewModel.onDateEditTextClicked()}"
android:hint="@string/hint_date"
android:imeOptions="actionDone"
android:inputType="none"
android:maxLines="1"
android:text="@={viewModel.filterDate}" />
(参见focusable, inputType和onClick)
在视图模型:
public void onDateEditTextClicked() {
// do something
}
如果你需要一个单一的功能，所有的活动，当调用将打开日期选择器，然后返回我选择的日期，然后为所有创建一个接口
public interface OnDatePickerLitionarCallBack {
void DatePicker(String selectedDate);
}
然后在活动中调用接口
public class MapsActivity extends FragmentActivity implements OnDatePickerLitionarCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
findViewById(R.id.date_pick).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
date_Picker(MapsActivity.this,MapsActivity.this);
}
});
}
@Override
public void DatePicker(String selectedDate) {
}
}
实现接口后，创建一个公共类用于访问任何活动或片段
public class Commons{
public static void date_Picker(Context context, OnDatePickerLitionarCallBack onDatePickerLitionarCallBack) {
final java.util.Calendar myCalendar = java.util.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(java.util.Calendar.YEAR, year);
myCalendar.set(java.util.Calendar.MONTH, monthOfYear);
myCalendar.set(java.util.Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "dd,MMM yyyy"; //In which you need put here
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(myFormat, Locale.US);
onDatePickerLitionarCallBack.DatePicker(sdf.format(myCalendar.getTime()));
}
};
DatePickerDialog datePickerDialog = new DatePickerDialog(context, date, myCalendar
.get(java.util.Calendar.YEAR), myCalendar.get(java.util.Calendar.MONTH),
myCalendar.get(java.util.Calendar.DAY_OF_MONTH));
datePickerDialog.show();
}
}
editText1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog.OnDateSetListener dpd = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
int s = monthOfYear + 1;
String a = dayOfMonth + "/" + s + "/" + year;
editText1.setText(a);
}
};
Time date = new Time();
DatePickerDialog d = new DatePickerDialog(UpdateStore.this, dpd, date.year, date.month, date.monthDay);
d.show();
}
});
