多个日期监听器

Question

我有这样的代码

    private void Picker() {
    Calendar now = Calendar.getInstance();
    Calendar maxDate = Calendar.getInstance();
    maxDate.add(Calendar.MONTH, 1);
    Calendar minDate = Calendar.getInstance();
    minDate.add(Calendar.DAY_OF_YEAR, 1);
    dataController = DatePickerDialog.newInstance(
            controller.this,
            now.get(Calendar.YEAR),
            now.get(Calendar.MONTH),
            now.get(Calendar.DAY_OF_MONTH)
    );

    dataController.setMinDate(minDate);
    dataController.setMaxDate(maxDate);
    dataController.setTitle("Data awizacji");

    inputdataController.setFocusable(false);

    inputdataController.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            datadataController.show(getFragmentManager(), "Data");
        }
    });


    Calendar from = Calendar.getInstance();
    Calendar frommaxDate = Calendar.getInstance();
    frommaxDate.add(Calendar.MONTH, 1);
    Calendar fromminDate = Calendar.getInstance();
    fromminDate.add(Calendar.DAY_OF_YEAR, 1);
    dataControllerSecond = DatePickerDialog.newInstance(
            controller.this,
            from.get(Calendar.YEAR),
            from.get(Calendar.MONTH),
            from.get(Calendar.DAY_OF_MONTH)
    );

   dataControllerSecond.setMinDate(fromminDate);
    dataControllerSecond.setMaxDate(frommaxDate);
    dataControllerSecond.setTitle("Data awizacji DO");

    inputdataControllerSecond.setFocusable(false);

    inputdataControllerSecond.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dataControllerSecond.show(getFragmentManager(), "Data spotkania");
        }
    });

}


@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
    now = Calendar.getInstance();
    now.set(year, monthOfYear, dayOfMonth);
inputdataController.setText(dateFormatter.format(now.getTime()));

    from = Calendar.getInstance();
    from.set(year, monthOfYear, dayOfMonth);
 inputdataControllerSecond.setText(dateFormatter.format(from.getTime()));
}

我真的不知道如何让两个输入相互独立...我的意思是当我从一个输入中选择一个选项时，它会在所有输入中选择...我想做两个独立的日期...你知道我错了什么吗？我看到一个问题，答案是说另一个听众，但我做了，但它仍然无法正常工作..我很困惑，我不知道如何制作......这对我来说太烦人了...可以有人救命？ :)（我不需要完美的代码，我只需要一些线索，我做的很糟糕..）

Answer 1

在类级别声明一个变量：

int type = 1;

并改变你的听众：

inputdataController.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        type = 1;
        datadataController.show(getFragmentManager(), "Data");
    }
});

和

inputdataControllerSecond.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        type = 2;
        dataControllerSecond.show(getFragmentManager(), "Data spotkania");
    }
});

然后在onDateSet()

@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
    if (type == 1) {
        now = Calendar.getInstance();
        now.set(year, monthOfYear, dayOfMonth);
        inputdataController.setText(dateFormatter.format(now.getTime()));
    } else if (type == 2) {
        from = Calendar.getInstance();
        from.set(year, monthOfYear, dayOfMonth);
        inputdataControllerSecond.setText(dateFormatter.format(from.getTime()));
    }
}
