隐藏在Android中的DatePicker年场？ [英] Hide Year field in Android DatePicker?

问题描述

我使用的是基本的DatePicker，我试图找出如何隐藏年字段的DatePickerDialog这样只有月和日是可见的。我不介意底层$ C $下年将依然存在，我只是想隐藏年字段的对话框。你知道的东西，如：

I'm using a basic DatePicker and I'm trying to figure out how to hide the Year field on the DatePickerDialog so that only the Month and Day are visible. I don't mind that the underlying code for the year would still be there, I'd just like to hide the Year Field in the Dialog. You know with something like:

((View) myYear).setVisibility(View.GONE);

我知道不起作用，因为myYear是INT不是一个视图，但类似的规定。这可能吗？

which I know doesn't work because myYear is a int not a View, but something along those lines. Is it possible?

推荐答案

这是我发现实现一个datepicker一个超级简单的方法是调用它的xml：

A super easy way that I found to implement a DatePicker is to call it in xml:

    <DatePicker
    android:id="@+id/thePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

然后隐藏哪个领域你想（在这种情况下，年）的java：

and then hide whichever field you want (in this case the year) in java:

    picker = (DatePicker) findViewById(R.id.thePicker);
    try {
        Field f[] = picker.getClass().getDeclaredFields();
        for (Field field : f) {
            if (field.getName().equals("mYearPicker")) {
                field.setAccessible(true);
                Object yearPicker = new Object();
                yearPicker = field.get(picker);
                ((View) yearPicker).setVisibility(View.GONE);
            }
        }
    } 
    catch (SecurityException e) {
        Log.d("ERROR", e.getMessage());
    } 
    catch (IllegalArgumentException e) {
        Log.d("ERROR", e.getMessage());
    } 
    catch (IllegalAccessException e) {
        Log.d("ERROR", e.getMessage());
    }
