我决定将Realm用于我的项目.我已经阅读了文档,无法理解如何将所有手机联系人导入我的Realm数据库.
以前有人做过这种项目吗?请帮忙.
我使用了Sugar ORM,它有一个批量插入选项. Realm是否有相同或有替代品?
这是我到目前为止所做的事情:
package com.advisualinc.switchchat.Realm_DB;
import io.realm.RealmObject;
import io.realm.annotations.PrimaryKey;
/**
* Created by Veeresh on 10/19/2015.
*/
public class R_ContactDB extends RealmObject {
private String name;
@PrimaryKey
private String phone;
private boolean matchedWithRecent;
private int status;
public R_ContactDB(String name, String phone, boolean matchedWithRecent, int status)
{
this.name = name;
this.phone = phone;
this.matchedWithRecent = matchedWithRecent;
this.status = status;
}
public R_ContactDB()
{
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public boolean isMatchedWithRecent() {
return matchedWithRecent;
}
public void setMatchedWithRecent(boolean matchedWithRecent) {
this.matchedWithRecent = matchedWithRecent;
}
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
}
解决方法:
使用Realm,不需要直接适用于SQLite中可用的批量插入的东西.不涉及查询语言的开销.
您可以通过单个写入事务中的Realm#copyToRealm批处理插入多个对象.
如果您需要导入JSON数据,则有Realm#createOrUpdateAllFromJson(JSONArray).
