开发中碰到个需求,需要在一个空间中选择完成开始和结束时间。实现的过程走的是程序员开发的老路子,找到轮子后自己改吧改吧就成了。
当时做的时候有几个需求:1.当天为最大的结束日期,2.最大选择范围1年,3.开始时间和结束时间可以为同一天。如有其他需求实现,可以参考代码改进一下。先上效果图:
视频点击后的虚影是屏幕录制的原因。实现步骤:(如有缺失什么资源,请告知。开始时间和结束时间显示自己布局内添加就可以)
1.自定义控件属性
2.自定义控件代码

3.自定义view用到的布局 appoint_calendarview.xml,对应日历控件如下面图片的部分。
<?xml version="1.0" encoding="utf-8"?>
定义控件选择后的背景部分:CalendarDayRelativeLayout.java
import android.content.Context; import android.graphics.Color; import android.os.Build; import android.support.annotation.RequiresApi; import android.util.AttributeSet; import android.widget.RelativeLayout; public class CalendarDayRelativeLayout extends RelativeLayout { public CalendarDayRelativeLayout(Context context) { this(context, null); } public CalendarDayRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); } @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN) public void isDurationSat(boolean isSaturday) { this.setBackground(getResources().getDrawable(R.drawable.appoint_calendar_sat_bg)); } @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN) public void isDurationSun(boolean isSunday) { this.setBackground(getResources().getDrawable(R.drawable.appoint_calendar_sun_bg)); } @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN) public void isETime(boolean etime) { // this.setBackgroundResource(getResources().getDrawable(R.drawable.)); this.setBackground(getResources().getDrawable(R.drawable.appoint_calendar_sat_bg)); } @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN) public void isSTime(boolean stime) { // this.setBackground(getResources().getDrawable(R.mipmap.appoint_calendar_start_bg)); this.setBackground(getResources().getDrawable(R.drawable.appoint_calendar_sun_bg)); } /** * 同一天 * */ @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN) public void isSameDay(){ this.setBackground(getResources().getDrawable(R.drawable.appoint_calendar_same_bg)); } }
自定义控件内日期的CalendarDayTextView.java
import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.graphics.Typeface; import android.util.AttributeSet; /** * @Description: 日历内日期 * @Author MengXY * @Date 2019/1/8 */ public class CalendarDayTextView extends android.support.v7.widget.AppCompatTextView { public boolean isToday; private boolean isSTime; private boolean isETime; private Context context; public void setEmptyColor(int emptyColor) { this.emptyColor = emptyColor; } public void setFillColor(int fillColor) { this.fillColor = fillColor; } private int emptyColor = Color.parseColor("#00ff00"); private int fillColor = Color.parseColor("#00ff00"); private Paint mPaintSTime; private Paint mPaintETime; public CalendarDayTextView(Context context) { super(context); initview(context); } public CalendarDayTextView(Context context, AttributeSet attrs) { super(context, attrs); initview(context); } private void initview(Context context) { this.context=context; // mPaintSTime = new Paint(Paint.ANTI_ALIAS_FLAG); // mPaintSTime.setStyle(Paint.Style.FILL); // mPaintSTime.setColor(context.getResources().getColor(R.color.date_time_bg)); // mPaintSTime.setStrokeWidth(2); // // mPaintETime = new Paint(Paint.ANTI_ALIAS_FLAG); // mPaintETime.setStyle(Paint.Style.FILL); // mPaintETime.setColor(context.getResources().getColor(R.color.date_time_bg)); // mPaintETime.setStrokeWidth(2); } @Override protected void onDraw(Canvas canvas) { //根据当前逻辑开始时间必须先绘制结束时间 // if (isETime) { // canvas.save(); // //移动到当前控件的中心,以中心为圆点绘制实心圆 // canvas.translate(getWidth() / 2, getHeight() / 2); // canvas.drawCircle(0, 0, getWidth() / 2 , mPaintETime); // canvas.restore(); // //此处必须将圆移动回开始位置,否则文本显示会受到影响 // canvas.translate(0, 0); // } // // if (isSTime) { // canvas.save(); // //移动到当前控件的中心,以中心为圆点绘制实心圆 // canvas.translate(getWidth() / 2, getHeight() / 2); // canvas.drawCircle(0, 0, getWidth() / 2 , mPaintSTime); // canvas.restore(); // //此处必须将圆移动回开始位置,否则文本显示会受到影响 // canvas.translate(0, 0); // } super.onDraw(canvas); } public void setToday(boolean today) { isToday = today; this.setTextColor(context.getResources().getColor(R.color.text_main_tab_select)); } public void isETime(boolean etime) { isETime = etime; // this.setTextColor(context.getResources().getColor(R.color.date_time_tv)); // this.setTypeface(Typeface.defaultFromStyle(Typeface.BOLD)); isSelected(true); } public void isSTime(boolean stime) { isSTime = stime; isSelected(true); // this.setTextColor(context.getResources().getColor(R.color.date_time_tv)); // this.setTypeface(Typeface.defaultFromStyle(Typeface.BOLD)); } public void isSelected(boolean isSelcted){ if(isSelcted){ this.setTextColor(context.getResources().getColor(R.color.date_time_tv)); this.setTypeface(Typeface.defaultFromStyle(Typeface.BOLD)); }else { this.setTextColor(context.getResources().getColor(R.color.text_lable)); } } }
appoint_calendarview.xml
<?xml version="1.0" encoding="utf-8"?>
calendar_text_day.xml
<?xml version="1.0" encoding="utf-8"?>
DateUtil.java
import java.sql.Timestamp; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; public class DateUtil { //Calendar 转化 String public static String calendarToStr(Calendar calendar,String format) { // Calendar calendat = Calendar.getInstance(); SimpleDateFormat sdf = new SimpleDateFormat(format); return sdf.format(calendar.getTime()); } //String 转化Calendar public static Calendar strToCalendar(String str,String format) { // String str = "2012-5-27"; SimpleDateFormat sdf = new SimpleDateFormat(format); Date date = null; Calendar calendar = null; try { date = sdf.parse(str); calendar = Calendar.getInstance(); calendar.setTime(date); } catch (ParseException e) { e.printStackTrace(); } return calendar; } // Date 转化String public static String dateTostr(Date date,String format) { SimpleDateFormat sdf = new SimpleDateFormat(format); // String dateStr = sdf.format(new Date()); String dateStr = sdf.format(date); return dateStr; } // String 转化Date public static Date strToDate(String str,String format) { SimpleDateFormat sdf = new SimpleDateFormat(format); Date date = null; try { date = sdf.parse(str); } catch (ParseException e) { e.printStackTrace(); } return date; } //Date 转化Calendar public static Calendar dateToCalendar(Date date) { Calendar calendar = Calendar.getInstance(); calendar.setTime(date); return calendar; } //Calendar转化Date public static Date calendarToDate(Calendar calendar) { return calendar.getTime(); } // String 转成 Timestamp public static Timestamp strToTimeStamp(String str) { // Timestamp ts = Timestamp.valueOf("2012-1-14 08:11:00"); return Timestamp.valueOf(str); } //Date 转 TimeStamp public static Timestamp dateToTimeStamp(Date date,String format) { SimpleDateFormat df = new SimpleDateFormat(format); String time = df.format(new Date()); Timestamp ts = Timestamp.valueOf(time); return ts; } }
4.资源文件 /drawableappoint_calendar_sat_bg.xml //开始时间
appoint_calendar_sun_bg.xml //结束时间
appoint_calendar_same_bg.xml //开始时间和结束时间是同一天
<?xml version="1.0" encoding="utf-8"?>
/value
日 一 二 三 四 五 六 #41D2C4
5.在activity中使用 activity_selectdate.xml
<?xml version="1.0" encoding="utf-8"?>
SelectTimeActivity.java
public class SelectTimeActivity extends BaseActivity { @BindView(R.id.tv_title) TextView tvTitle; @BindView(R.id.iv_title_back) ImageView ivTitleBack; @BindView(R.id.tv_title_left) TextView tvTitleLeft; @BindView(R.id.layout_title_left) RelativeLayout layoutTitleLeft; @BindView(R.id.tv_title_right) TextView tvTitleRight; @BindView(R.id.layout_title_right) RelativeLayout layoutTitleRight; @BindView(R.id.layout_line) FrameLayout layoutLine; @BindView(R.id.tv_startime) TextView tvStartime; @BindView(R.id.tv_endtime) TextView tvEndtime; @BindView(R.id.calendarview) CalendarView calendarview; private String starTime; private String endTime; private boolean isSelecgOk = false; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_selectdate); ButterKnife.bind(this); setStatusBar(true); initView(); } private void initView() { tvTitle.setText(getString(R.string.selectTime)); ivTitleBack.setVisibility(View.GONE); tvTitleLeft.setText(getString(R.string.cancel)); tvTitleRight.setText(getString(R.string.confirm)); calendarview.setETimeSelListener(new CalendarView.CalendatEtimSelListener() { @Override public void onETimeSelect(Date date) { if (date != null) { endTime = DateUtils.formatData(date, Constant.TFORMATE_YMD); tvEndtime.setText(endTime); }else { endTime = null; } } }); calendarview.setSTimeSelListener(new CalendarView.CalendarSTimeSelListener() { @Override public void onSTimeSelect(Date date) { if (date != null) { starTime = DateUtils.formatData(date, Constant.TFORMATE_YMD); tvStartime.setText(starTime); }else { starTime = null; } } }); calendarview.setCalendaSelListener(new CalendarView.CalendaSelListener() { @Override public void selectStatus(boolean isOk) { isSelecgOk = isOk; } }); } @OnClick({R.id.tv_title_left, R.id.tv_title_right}) public void onClick(View view) { switch (view.getId()) { case R.id.tv_title_left: finish(); break; case R.id.tv_title_right: if(TextUtils.isEmpty(starTime)){ ToastUtils.showToast(getString(R.string.history_alert1)); return; } if(TextUtils.isEmpty(endTime) || !isSelecgOk){ ToastUtils.showToast(getResources().getString(R.string.history_alert)); return; } Intent intent = new Intent(); intent.putExtra("starTime",starTime); intent.putExtra("endTime",endTime); setResult(RESULT_OK,intent); finish(); break; } } }
