同一活动中 Edittext 的多个日期选择器

Question

在我的应用程序中，我有两个 edittext 并且我想要当单击打开的两个 edittext datepicker 对话框并在编辑文本中设置两个值时。

final 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);
            updateDOB();
            updateDOA();
        }

    };
    doa.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            new DatePickerDialog(FamilyEditActivity.this, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH)).show();
        }
    });
    spoucedob.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            new DatePickerDialog(FamilyEditActivity.this, date, myCalendar
                    .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                    myCalendar.get(Calendar.DAY_OF_MONTH)).show();
        }
    });
}

private void updateDOA() {
    String myFormat = "yyyy-MM-dd";
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    doa.setText(sdf.format(myCalendar.getTime()));
}
private void updateDOB() {
    String myFormat = "yyyy-MM-dd";
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    spoucedob.setText(sdf.format(myCalendar.getTime()));
}

这是我的代码。当我在一个 edittext 中设置日期时，它会同时更改其他 edittext 值。请告诉我是什么问题...谢谢。

Answer 1

在类级别声明一个变量：

EditText clickedEditText;

并在点击侦听器中将其设置为点击的 EditText：

doa.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        clickedEditText = (EditText) view;
        new DatePickerDialog(FamilyEditActivity.this, date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    }
});
spoucedob.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        clickedEditText = (EditText) view;
        new DatePickerDialog(FamilyEditActivity.this, date, myCalendar
                .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    }
});

现在你只需要一种方法update()：

private void update() {
    String myFormat = "yyyy-MM-dd";
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    clickedEditText.setText(sdf.format(myCalendar.getTime()));
}

并在onDateSet()：

final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,                               int dayOfMonth) {
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
            update();
        }
};
