Question

在Android中创建出勤活动。我必须在日历中以不同的颜色显示“现在”，“离开”，“缺席”显示。如何在日历中显示？

Answer 1

我希望这对您有用。

使用Caldroid库。

从服务器获取数据。制作不同日期的数组列表，即（现在，缺席，离开）。

并根据当前日期（例如绿色），缺席（例如红色）和休假（例如蓝色）为日期分配颜色

在build.gradle文件中添加依赖项

 implementation 'com.roomorama:caldroid:3.0.1'

在包中添加以下活动。

import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;

                Toast.makeText(getApplicationContext(), formatter.format(date),
                        Toast.LENGTH_SHORT).show();

            @Override

activity_main1.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <LinearLayout
            android:id="@+id/calendar1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"></LinearLayout>

    </LinearLayout>
</ScrollView>

添加了硬编码日期而不是该日期，从json解析日期添加到特定列表中。我希望这对您有用。
