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。
当前回答
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();
}
});
其他回答
EditText text = (EditText) findViewById(R.id.editText);
text.setOnClickListener(new OnClickListener(){
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onClick(View view) {
DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
String date = i2 + "/" + (++i1) + "/" + i;
text.setText(date);
}
},year,month,date);
}
});
datePickerDialog.show();
您还可以通过这些语句设置最小日期和最大日期。
datepickerDialoge.getDatepicker().setMinDate(long Date);
datepickerDialoge.getDatepicker().setMaxDate(long Date);
注意:在datepickerDialog.show()之前添加这些行;声明 你会得到这样的日期=12/2/2017。
我希望我的回答能有所帮助。
class MyClass implements OnClickListener, OnDateSetListener {
EditText editText;
this.editText = (EditText) findViewById(R.id.editText);
this.editText.setOnClickListener(this);
@Override
public void onClick(View v) {
DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
dialog.show();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
}
}
下面是Material Date Picker的Kotlin扩展函数:
fun TextInputEditText.datePicker(fm:FragmentManager, tag: String) {
isFocusableInTouchMode = false
isClickable = true
isFocusable = false
val datePicker =
MaterialDatePicker.Builder.datePicker()
.setTitleText("Select Date")
.build()
setOnClickListener {
datePicker.show(fm,"tag")
}
datePicker.addOnPositiveButtonClickListener {
setText(datePicker.headerText)
Log.d("TAG", "datePicker: \n $it")
}}
用法:
在活动:
yourTextInputEditText.datePicker(supportFragmentManager,"tag")
在片段:
yourTextInputEditText.datePicker(requireActivity().supportFragmentManager,"tag")
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。
<EditText
android:id="@+id/date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:hint="DD/MM/YYYY"
android:inputType="date"
android:focusable="false"/>
<EditText
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="00:00"
android:inputType="time"
android:focusable="false"/>

final Calendar c = Calendar.getInstance();
mHour = c.get(Calendar.HOUR_OF_DAY);
