当我点击edidtext时，我看到了datePicker。
public class DateDialog extends DialogFragment implements DatePickerDialog.OnDateSet`enter code here`Listener {
EditText txtDate ;
public DateDialog(View view){
txtDate=(EditText)view;
}
public Dialog onCreateDialog(Bundle savedInstanceState){
final Calendar c = Calendar.getInstance();
int day = c.get(Calendar.DAY_OF_MONTH);
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
return new DatePickerDialog(getActivity(), this, year ,month,day) ;
}
public void onDateSet (DatePicker view, int year , int month ,int day ){
String date = day+ "-" + (month + 1)+"-"+year;
txtDate.setText(date);
}
}
然后日期值进入editText。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_page_);
}
public void onStart(){
super.onStart();
EditText txtDate = (EditText)findViewById(R.id.editDate);
txtDate.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
DateDialog dialog = new DateDialog(v);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
dialog.show(ft, "DatePicker");
}
}
});
我要添加的方法。
private String getDate() {
SimpleDateFormat dateFormat = new SimpleDateFormat
("dd-MM-yyyy", Locale.getDefault());
Date date = new Date();
return dateFormat.format(date);
}
public long addPage(Page page){
ContentValues values = new ContentValues();
values.put(PageSQLITE.COL_DATE_PAGE, getDate());
values.put(PageSQLITE .COL_TITLE_PAGE,page.getTitrePage());
return bdd.insert(PageSQLITE.TABLE_PAGE, null, values);
当我使用“onclick”保存日期值时，我有IllegalArgumentException。
private String strTitle;
private String datePage;
public void onClickAdd(View v) {
strTitle = ((EditText) findViewById(R.id.editTitle)).getText().toString();
datePage = ((EditText) findViewById(R.id.editDate)).getText().toString();
Page page = new Page(strTitle, new Date( datePage) );
PageMgr pageMgr = new PageMgr(this);
pageMgr.open();
pageMgr.addPage(page);
}
最后我看到了这条消息。

答案 0 :(得分：0)
嗯，这里有一个空白字符："dd-MM-yyyy ";删除它，我认为它会起作用：）
答案 1 :(得分：0)
I finally find the answer just:
wrong date
SimpleDateFormat dateFormat = new SimpleDateFormat
("dd-MM-yyyy", Locale.getDefault());
correct date
SimpleDateFormat dateFormat = new SimpleDateFormat
("dd/MM/yyyy", Locale.FRENCH);
and similar for
public void onDateSet (DatePicker view, int year , int month ,int day ){
String date = day+ "/" + (month + 1)+"/"+year ;
txtDate.setText(date);
答案 2 :(得分：0)
您可以轻松实现此功能。没有必要将EditText对象传递给Date Picker片段。您需要创建一个接口并将此接口实现为activity / fragment。并从Date Picker Fragment调用该方法。
您可以使用Textview而不是Edit Test，并且可以在文本视图上单击显示日期对话框片段。
dateTextView.setonClickListener(new OnClickListener{
@Override
public void onClick(View v) {
Dialog dialog;
switch (v.getId()) {
case R.id.render_date:
try {
Calendar calendar = Calendar.getInstance();
dialog = new DatePickerDialog(EventDetailActivity.this, this, calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.setCancelable(true);
dialog.show();
} catch (ParseException e) {
e.printStackTrace();
}
break;
}
}
})
在您的activity / fragment中实现DatePickerDialog.OnDateSetListener接口。
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
TextView textView = (TextView) findViewById(R.id.date);
textView.setText("**Set your date here**");
}
