android - android 中的日期选择器

Question

我想要可以在其中选择年、月和日期的日期选择器。像这样，

但我得到这样的日期选择器，

我想选择年份和月份，但在上面的日期选择器中我只能选择月份这是我的代码:

DatePickerDialog.OnDateSetListener mDateListener;

edBirthday.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Calendar cal = Calendar.getInstance();
                int year = cal.get(Calendar.YEAR);
                int month = cal.get(Calendar.MONTH);
                int day = cal.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog dialog =  new DatePickerDialog(
                        RegisterActivity.this,
                        android.R.style.Theme_Holo_Light_Dialog_MinWidth,
                        mDateListener,
                        year,month,day
                );
                dialog.getWindow().setBackgroundDrawable( new ColorDrawable( Color.TRANSPARENT ) );
                dialog.show();
            }
        } );

        mDateListener = new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker datePicker ,int year ,int month ,int day) {
                month = month + 1;

                Log.d( "onDateSet" , month + "/" + day + "/" + year );
                edBirthday.setText( new StringBuilder().append( day ).append( "-" )
                        .append( month ).append( "-" ).append( year ) );
            }
        };

是的，这可以使用自定义对话框，

创建 lay_calander.xml

<DatePicker xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/datePicker"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:calendarViewShown="false"
    android:datePickerMode="spinner" />

为您的自定义对话框创建 Java 类，

import android.app.DatePickerDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v7.app.AlertDialog;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.DatePicker;

import java.util.Calendar;

public class MyDatePickerDialog extends AlertDialog implements DialogInterface.OnClickListener, DatePicker.OnDateChangedListener {

    private DatePickerDialog.OnDateSetListener mDateSetListener;
    private DatePicker mDatePicker;

    protected MyDatePickerDialog(@NonNull Context context) {
        super(context);
        init();
    }

    protected MyDatePickerDialog(@NonNull Context context, int themeResId) {
        super(context, themeResId);
        init();
    }

    protected MyDatePickerDialog(@NonNull Context context, boolean cancelable, @Nullable OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
        init();
    }


    private void init() {
        View view = LayoutInflater.from(getContext()).inflate(R.layout.lay_calander, null);
        mDatePicker = view.findViewById(R.id.datePicker);
        setView(view);
    }

    public void showDatePicker(DatePickerDialog.OnDateSetListener listener, Calendar defaultDate) {

        setButton(BUTTON_POSITIVE, getContext().getString(android.R.string.ok), this);
        setButton(BUTTON_NEGATIVE, getContext().getString(android.R.string.cancel), this);

        mDateSetListener = listener;

        if (defaultDate == null) {
            defaultDate = Calendar.getInstance();

        }
        int year = defaultDate.get(Calendar.YEAR);
        int monthOfYear = defaultDate.get(Calendar.MONTH);
        int dayOfMonth = defaultDate.get(Calendar.DAY_OF_MONTH);
        mDatePicker.init(year, monthOfYear, dayOfMonth, this);

        show();

    }


    @Override
    public void onClick(@NonNull DialogInterface dialog, int which) {
        switch (which) {
            case BUTTON_POSITIVE:
                if (mDateSetListener != null) {
                    // Clearing focus forces the dialog to commit any pending
                    // changes, e.g. typed text in a NumberPicker.
                    mDatePicker.clearFocus();
                    if (mDateSetListener != null) {
                        mDateSetListener.onDateSet(mDatePicker, mDatePicker.getYear(),
                                mDatePicker.getMonth(), mDatePicker.getDayOfMonth());
                    }
                }
                break;
            case BUTTON_NEGATIVE:
                cancel();
                break;
        }
    }

    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        mDatePicker.init(year, monthOfYear, dayOfMonth, this);
    }
}

从您的 Activity 中调用对话框，

MyDatePickerDialog dialog = new MyDatePickerDialog(this);
        dialog.setTitle("Set Date");
        dialog.showDatePicker(new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                //Date select callback
            }
        }, Calendar.getInstance());

你的输出看起来像，

确保你的 AppTheme 应该是 Extend AppCompat， list - android:theme="@style/AppTheme"

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
