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。

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();

        }
    });

把这4行放在(EditText, AppCompatEditText)上。它不会显示键盘。然后在clicklistener上,你可以显示datePicker

android:clickable="false" 
   android:cursorVisible="false" 
   android:focusable="false" 
   android:focusableInTouchMode="false"

选中的答案不太适合我,因为我必须点击EditText框一次,然后在OnClickListener启动之前再次点击它。我能够通过用OnTouchListener替换OnClickListener来修复这个问题,以防有人遇到类似的问题,下面是我的代码看起来是什么样的:

Calendar myCalendar = 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(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, monthOfYear);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        updateLabel();
    }

};
edittext.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public void onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {
            new DatePickerDialog(classname.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"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

    edittext.setText(sdf.format(myCalendar.getTime()));
}

我不能得到这些工作中的任何人,所以将添加我的一个,以防它有帮助。

public class MyEditTextDatePicker  implements OnClickListener, OnDateSetListener {   
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;

public MyEditTextDatePicker(Context context, int editTextViewID)
{       
    Activity act = (Activity)context;
    this._editText = (EditText)act.findViewById(editTextViewID);
    this._editText.setOnClickListener(this);
    this._context = context;
}

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    _birthYear = year;
    _month = monthOfYear;
    _day = dayOfMonth;
    updateDisplay();
}
@Override
public void onClick(View v) {
    Calendar calendar = Calendar.getInstance(TimeZone.getDefault());

    DatePickerDialog dialog = new DatePickerDialog(_context, this,
            calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
            calendar.get(Calendar.DAY_OF_MONTH));
    dialog.show();
    
}

// updates the date in the birth date EditText
private void updateDisplay() {

    _editText.setText(new StringBuilder()
    // Month is 0 based so add 1
    .append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}

还有其他书里没有提到的东西。确保将以下内容放在EditText xml上。

android:focusable="false"

否则,就像在我的例子中,键盘会不断弹出。

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
}
public class DatePickerActivity extends AppCompatActivity {
    Button button;
    static TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button= (Button) findViewById(R.id.btn_click);
        textView= (TextView) findViewById(R.id.txt_date);



        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                DialogFragment newFragment=new DatePickerFragment();
                newFragment.show(getFragmentManager(), "datepicker");
            }
        });

    }

    public class DatePickerFragment extends DialogFragment implements    DatePickerDialog.OnDateSetListener{
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear, int  day) {
            String years=""+year;
            String months=""+(monthOfYear+1);
            String days=""+day;
            if(monthOfYear>=0 && monthOfYear<9){
                months="0"+(monthOfYear+1);
            }
            if(day>0 && day<10){
                days="0"+day;

            }
            textView.setText(days+"/"+months+"/"+years);


        }

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            //use the current date as the default date in the 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);
            DatePickerDialog datePickerDialog=null;
            datePickerDialog=new DatePickerDialog(getActivity(), this, year,  month, day);

            return datePickerDialog;
        }

    }

}
