鉴于巴友的热情特附上源码：https://yunpan.cn/c6wUG8QSvVSnC 访问密码 9a49
首先是MainActivity，源码如下
<pre name="code" class="java">public class MainActivity extends Activity {
private SignCalendar calendar;
private String date;
private int years;
private String months;
private Button btn_sign;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
Date curDate = new Date(System.currentTimeMillis());// 获取当前时间
date = formatter.format(curDate);
calendar = (SignCalendar) findViewById(R.id.sc_main);
btn_sign = (Button) findViewById(R.id.btn_sign);
btn_sign.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
List<String> list = new ArrayList<String>();
list.add("2016-06-30");
list.add(date);
// calendar.setCalendarDaysBgColor(list,
// R.drawable.bg_sign_today);
calendar.addMarks(list, 0);
}
});
}
}下面是布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" 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.h.cheng.signcalendar.MainActivity" > <com.h.cheng.signcalendar.SignCalendar android:id="@+id/sc_main" android:layout_width="match_parent" android:layout_height="320dp" android:clickable="true" > </com.h.cheng.signcalendar.SignCalendar> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="15dp" android:orientation="horizontal" > <Button android:id="@+id/btn_sign" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="15dp" android:layout_marginRight="15dp" android:background="#f00" android:text="签到" android:textColor="#fff" /> </LinearLayout> </LinearLayout>
这是运行效果，签到的背景图片可以自定义
最后是自定义控件，源码如下：
