Android自定义view实现日历打卡签到
本文实例为大家分享了Android自定义view实现日历打卡签到的具体代码,供大家参考,具体内容如下
1.说明
自己写一个view实现每天签到的功能,设置背景图片
2.效果图
3.主界面
package com.example.myapplication30; import androidx.appcompat.app.AppCompatActivity; import android.annotation.SuppressLint; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.TextView; import java.util.ArrayList; import java.util.Calendar; import java.util.List; public class MainActivity extends AppCompatActivity { //参考网址:https://blog.csdn.net/MacaoPark/article/details/102069775 private TextView mTvDaySum; private TextView mTvMonth; private SignView mCvCalendar; private List<SignEntity> data; private Calendar calendar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTvDaySum = findViewById(R.id.punch_tv_day_sum); mTvMonth = findViewById(R.id.punch_tv_month); mCvCalendar = findViewById(R.id.punch_cv_calendar); } @Override protected void onStart() { super.onStart(); onReady(); } @SuppressLint("SetTextI18n") private void onReady() { calendar = Calendar.getInstance(); int year = calendar.get(Calendar.YEAR); int month = calendar.get(Calendar.MONTH); //int date = calendar.get(Calendar.DATE); int dayOfMonthToday = calendar.get(Calendar.DAY_OF_MONTH); List<SignDate> signDates = new ArrayList<>(); signDates.add(new SignDate(2021, 5, 1, true)); signDates.add(new SignDate(2021, 5, 2, true)); signDates.add(new SignDate(2021, 5, 3, true)); signDates.add(new SignDate(2021, 5, 4, true)); signDates.add(new SignDate(2021, 5, 5, true)); mTvDaySum.setText("本期连续登录\t"+signDates.size()+"\t天"); mTvMonth.setText(year+"年"+getResources().getStringArray(R.array.month_array)[month]+"\t"+dayOfMonthToday+"日"); data = new ArrayList<>(); for (int i = 1; i <= dayOfMonthToday; i++) { SignEntity signEntity = new SignEntity(); if (i == dayOfMonthToday) { signEntity.setDayType(2); } else { signEntity.setDayType(1); } for (int j = 0; j < signDates.size(); j++) { if (signDates.get(j).getDay() == i) { signEntity.setDayType(0); break; } else if (dayOfMonthToday == i) { signEntity.setDayType(2); } else { signEntity.setDayType(1); } } data.add(signEntity); } SignAdapter signAdapter = new SignAdapter(data); mCvCalendar.setAdapter(signAdapter); } }
4.适配器
package com.example.myapplication30; import java.util.List; /** * SignAdapter * Created by E.M on 2016/4/21. */ public class SignAdapter extends CalendarAdapter { private List<SignEntity> data; public SignAdapter(List<SignEntity> data) { this.data = data; } @Override public SignView.DayType getType(int dayOfMonth) { return SignView.DayType.valueOf(data.get(dayOfMonth - 1).getDayType()); } }
