从Google Calendar取出Scheduler

设定日历数据类

public class Scheduler {
	/**
	 * event id
	 */
	private long eventID;
	/**
	 * the scheduler's date, like "MM/dd/yyyy"
	 */
	private String date;
	/**
	 * the value of begin time
	 */
	private String beginTime;
	/**
	 * the value of end time
	 */
	private String endTime;
	/**
	 * the scheduler's title
	 */
	private String title;
	/**
	 * the scheduler's description 
	 */
	private String description;
	
	
	
	public long getEventID() {
		return eventID;
	}
	public void setEventID(long eventID) {
		this.eventID = eventID;
	}
	public String getDate() {
		return date;
	}
	public void setDate(String date) {
		this.date = date;
	}
	public String getBeginTime() {
		return beginTime;
	}
	public void setBeginTime(String beginTime) {
		this.beginTime = beginTime;
	}
	public String getEndTime() {
		return endTime;
	}
	public void setEndTime(String endTime) {
		this.endTime = endTime;
	}
	public String getTitle() {
		return title;
	}
	public void setTitle(String title) {
		this.title = title;
	}
	public String getDescription() {
		return description;
	}
	public void setDescription(String description) {
		this.description = description;
	}
	
}

建立查找类（实现取得当天的计划）

直接能用，接口做了sdk版本控制，4.0一下的sdk不支持该Calendar，会直接返回null

通过google账户查询的话用如下方法：

// Projection array. Creating indices for this array instead of doing
// dynamic lookups improves performance.
public static final String[] EVENT_PROJECTION = new String[] {
    Calendars._ID,                           // 0
    Calendars.ACCOUNT_NAME,                  // 1
    Calendars.CALENDAR_DISPLAY_NAME,         // 2
    Calendars.OWNER_ACCOUNT                  // 3
};
  
// The indices for the projection array above.
private static final int PROJECTION_ID_INDEX = 0;
private static final int PROJECTION_ACCOUNT_NAME_INDEX = 1;
private static final int PROJECTION_DISPLAY_NAME_INDEX = 2;
private static final int PROJECTION_OWNER_ACCOUNT_INDEX = 3;

// Run query
Cursor cur = null;
ContentResolver cr = getContentResolver();
Uri uri = Calendars.CONTENT_URI;   
String selection = "((" + Calendars.ACCOUNT_NAME + " = ?) AND (" 
                        + Calendars.ACCOUNT_TYPE + " = ?) AND ("
                        + Calendars.OWNER_ACCOUNT + " = ?))";
String[] selectionArgs = new String[] {"[email protected]", "com.google",
        "[email protected]"}; 
// Submit the query and get a Cursor object back. 
cur = cr.query(uri, EVENT_PROJECTION, selection, selectionArgs, null);
