Android日历控件

这个日历控件主要是在material-canendarview的基础上修改，符合自己的项目中。
主要针对上面问题
1、选择时间后，标题没有改变，但下面日历已经改变
2、滑动的时间错乱问题。

github上开源项目地址
https://github.com/prolificinteractive/material-calendarview

效果图：

选择年月

在开源项目中主要修改的类

注意：通CalendarView的月从0-11，如果用获取的话，month得加1

代码如下

                c.setTime(date);
                int year = c.get(Calendar.YEAR);
                int month = c.get(Calendar.MONTH);
                Log.i("year-----", year + "");

    }

    @Override
    public void onClick(View v) {
        timePickerView.setTime(new Date());
        timePickerView.show();
    }
}

2、DatePicker

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    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.example.mydatepicker.MainActivity">

    <Button
        android:text="选择时间"
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <EditText
        android:hint=""
        android:id="@+id/ed_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

package com.example.mydatepicker;

import android.app.DatePickerDialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {
    private Button btn;
    private Calendar calendar; //通过Calendar获取系统时间
    private int mYear;
    private int mMonth;
    private int mDay;
    private int mHour;
    private int mMinute;
    private EditText ed_text;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn= (Button) findViewById(R.id.btn);
        calendar = Calendar.getInstance();
        ed_text= (EditText) findViewById(R.id.ed_text);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int day) {
                        // TODO Auto-generated method stub
                        mYear = year;
                        mMonth = month;
                        mDay = day;
                      //  更新EditText控件日期 小于10加0
                        ed_text.setText(year + "-" + (mMonth + 1) + "-" + mDay );
                    }
                }, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
                        calendar.get(Calendar.DAY_OF_MONTH) ).show();
            }
        });

    }
}

3、DatePicker取消问题

datepicker如果没有设置取消，点击空白时和点击返回按钮时，都也会把时间默认的选中。因此要设置取消按钮

   tv_startTime.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Calendar cal = Calendar.getInstance();
                final DatePickerDialog mDialog = new DatePickerDialog(getActivity(), null,
                        cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH));

                //手动设置按钮
                mDialog.setButton(DialogInterface.BUTTON_POSITIVE, "完成", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        //通过mDialog.getDatePicker()获得dialog上的DatePicker组件，然后可以获取日期信息
                        DatePicker datePicker = mDialog.getDatePicker();
                        int year = datePicker.getYear();
                        int month = datePicker.getMonth();
                        int day = datePicker.getDayOfMonth();
                        tv_startTime.setText(year + "-" + (month + 1) + "-" + day);
                    }
                });
                //取消按钮，如果不需要直接不设置即可
                mDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                    }
                });

                mDialog.show();
            }
        });
