Question

正如你所知，我正在使用日期选择器（不同语言......最重要的是2015年11月写的）。

我正在使用OnClickListener，当点击a1 EditText时，会弹出DatePicker对话框，您可以选择日期，完成后会在EditText中收到日期。

但是我在对话框的构造按钮和选择年份方面遇到了麻烦，它们是不可见的，我只能点击它们，虽然没有看到它们。

如何启用/显示确认按钮和年份日期选择？

Activity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_first_entry"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.none.myapplication.firstEntry">
<EditText
        android:id="@+id/a1"
        android:layout_below="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>

Activity.java

private EditText a1;
private DatePickerDialog fromDatePickerDialog;
private SimpleDateFormat dateFormatter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first_entry);


    dateFormatter = new SimpleDateFormat("dd-MM-yyyy");

    findViewsById();

    setDateTimeField();

}
private void findViewsById() {
    a1 = (EditText) findViewById(R.id.a1);
    a1.setInputType(InputType.TYPE_NULL);
    a1.requestFocus();
}

private void setDateTimeField() {
    a1.setOnClickListener(this);

    Calendar newCalendar = Calendar.getInstance();
    fromDatePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            Calendar newDate = Calendar.getInstance();
            newDate.set(year, monthOfYear, dayOfMonth);
            a1.setText(dateFormatter.format(newDate.getTime()));
        }

    },newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}


@Override
public void onClick(View view) {
    if(view == a1) {
        fromDatePickerDialog.show();
    }
}

Answer 1

fromDatePickerDialog = new DatePickerDialog(this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
    //rest of the code
}

并在你的styles.xml中

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@color/blue_500</item>
</style>

检查此代码段 -

public void showDatePickerDialog(){

        DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));
        datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        datePickerDialog.show();
       //clientDate.setText(""+myCalendar.get(Calendar.DAY_OF_MONTH)+"/"+(myCalendar.get(Calendar.MONTH)+1)+"/"+myCalendar.get(Calendar.YEAR));
    }


    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);
            //updateYourLabel(); // or whatever you want
            //Toast.makeText(context, ""+dayOfMonth+"/"+(monthOfYear+1)+"/"+year, Toast.LENGTH_SHORT).show();
            clientDate.setText(""+dayOfMonth+"/"+(monthOfYear+1)+"/"+year);
        }

    };

对于那些没有得到上述解决方案有用的人，试试这个解决方案-

styles.xml:

<!--  Date Picker Styles   -->
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">@color/titletext_blue</item>           <!-- Header Background -->
    <item name="android:colorAccent">@color/titletext_blue</item>
    <item name="android:textColor">@color/titletext_blue</item>
    <item name="android:buttonBarPositiveButtonStyle">@style/DialogButtonStyled</item>
    <item name="android:buttonBarNegativeButtonStyle">@style/DialogButtonStyled</item>
    <item name="android:buttonBarNeutralButtonStyle">@style/DialogButtonStyled</item>
    <item name="android:colorControlActivated">#4971AC</item>        <!--selected day-->
    <!--        <item name="android:textColorPrimary">#89B5F6</item> &lt;!&ndash;days of the month&ndash;&gt;-->
    <!--        <item name="android:textColorSecondary">#0E3E85</item>    &lt;!&ndash;days of the week&ndash;&gt;-->
</style>

<!-- Date picker ok/cancel button styles    -->
<style name="DialogButtonStyled" parent="Theme.MaterialComponents.Light">
    <item name="android:textColor">@color/titletext_blue</item>
    <item name="android:background">@color/transparent</item>
    <item name="android:textSize">15dp</item>
</style>

并调用日期选择器如下：

new DatePickerDialog(getActivity(), R.style.DialogTheme,(DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);

这应该对你有帮助:) 干杯！
