Android端通话记录读取

Android端读取手机通话记录，直接上代码：
public class CallInfo {
public String name;
public String number; // 号码
public long date; // 日期
public int type; // 类型：来电、去电、未接
public String duration;
private static CallInfo singleton=null;
public static synchronized CallInfo getInstance(String name, String number, long date, int type, String duration){
// if(singleton==null){
// singleton = new CallInfo(name,number,date,type,duration);
// }
singleton = new CallInfo(name,number,date,type,duration);
return singleton;
}

public CallInfo(String name, String number, long date, int type, String duration) {    this.name = name;    this.number = number;    this.date = date;    this.type = type;    this.duration = duration;}public String getName() {    return name;}public void setName(String name) {    this.name = name;}public String getNumber() {    return number;}public void setNumber(String number) {    this.number = number;}public long getDate() {    return date;}public void setDate(long date) {    this.date = date;}public int getType() {    return type;}public void setType(int type) {    this.type = type;}public String getDuration() {    return duration;}public void setDuration(String duration) {    this.duration = duration;}

}
