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。

日期选择对话框
Calendar c=Calendar.getInstance();
Integer month=c.get(Calendar.MONTH);
Integer day=c.get(Calendar.DAY_OF_MONTH);
Integer year=c.get(Calendar.YEAR);
DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et_from.setText(dayOfMonth+"/"+month+"/"+year);
}
},year,month,day);
datePickerDialog.show();

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。
试试这个:
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
DataPickerListener listener;
public DatePickerFragment(DataPickerListener l) {
listener = l;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the date picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(),
AlertDialog.THEME_HOLO_LIGHT, this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
month = month + 1;
String stringOfDate = day + "-" + month + "-" + year;
listener.setDate(stringOfDate);
Util.Log(stringOfDate);
}
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
super.onCancel(dialog);
listener.cancel();
}
public static interface DataPickerListener {
void setDate(String date);
void cancel();
}
}
// use this function to open datePicker popup
DialogFragment newFragment;
public void pickDate() {
if (newFragment == null)
newFragment = new DatePickerFragment(new PickDateListener());
newFragment.show(getFragmentManager(), "Date Picker");
}
class PickDateListener implements DataPickerListener {
@Override
public void setDate(String date) {
createSpiner(date);
onetouch = false;
}
@Override
public void cancel() {
onetouch = false;
}
}
使用@DrunkenDaddy扩展函数，至少在我的情况下(以编程方式创建EditText)，它在第一次单击时显示键盘，然后在第二次单击时显示日期选择器。
显然，将isFocusable和isFocusableInTouchMode设置为false是无关紧要的，因为第一次点击总是被EditText解释为焦点变化。因此，当EditText获得焦点时，我必须触发单击。现在它像预期的那样工作:第一次点击它直接打开日期选择器，而不是键盘(感谢设置showSoftInputOnFocus为false):
fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
isClickable = true
showSoftInputOnFocus = false
isCursorVisible = false
setOnFocusChangeListener { _, hasFocus -> if (hasFocus) callOnClick()}
val myCalendar = Calendar.getInstance()
val datePickerOnDataSetListener =
DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
myCalendar.set(Calendar.YEAR, year)
myCalendar.set(Calendar.MONTH, monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
val sdf = SimpleDateFormat(format, Locale.getDefault())
setText(sdf.format(myCalendar.time))
}
setOnClickListener {
DatePickerDialog(
context, datePickerOnDataSetListener,
myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)
).run {
maxDate?.time?.also { datePicker.maxDate = it }
show()
}
}
public class DatePickerActivity extends AppCompatActivity {
Button button;
static TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
