Bmob后端云的使用（2）——云端数据库的使用

1、初始化实体类

package com.xmut.aidhealthier.been;

import android.provider.ContactsContract.Contacts.Data;

import cn.bmob.v3.BmobObject;

import cn.bmob.v3.datatype.BmobFile;

public class EleRecords extends BmobObject {

public BmobFile getImage() {

}
public void setImage(BmobFile image) {

}
public MyUser getAuthor() {

}
public void setAuthor(MyUser author) {

}
public Data getckdate() {

}

}
public String getEdt_other() {

}
public String getEdt_yds60() {
return edt_yds60;
}
public void setEdt_yds60(String edt_yds60) {

}
public String getEdt_yds120() {

}

}
public void setEdt_ctkf(String edt_ctkf) {

}
public String getEdt_ct60() {

}
public void setEdt_ct60(String edt_ct60) {

}
public String getEdt_ct120() {
return edt_ct120;
}
public void setEdt_ct120(String edt_ct120) {

}
public void setEdt_ydskt(String edt_ydskt) {

}
public String getEdt_kydxbkt() {
return edt_kydxbkt;
}
public void setEdt_kydxbkt(String edt_kydxbkt) {
this.edt_kydxbkt = edt_kydxbkt;
}

}

2、新建数据库和数据添加方法（XML文件略）

  package com.xmut.aidhealthier.elerecords;

import java.io.Serializable;

btn_cancle = (Button) findViewById(R.id.btn_cancel);
cdate = (EditText) findViewById(R.id.edt_date);

btn_cancle.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

finish();
}
});

}

/**

if (edt_title.equals("")) {
Toast.makeText(EleRecordsActivity.this, "标题不能为空",

return;
}
EleRecords eleRecordsObj = new EleRecords();
eleRecordsObj.setAuthor(user);

}

3、云端数据读取并以listview列表显示部分信息和item点击事件（XML略）

package com.xmut.aidhealthier.elerecords;

// item点击事件
listView.setOnItemClickListener(this);

}

/**

*/
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
//获取当前用户
MyUser user = BmobUser.getCurrentUser(this, MyUser.class);
// 新建map对象，装载hashmap数据并存入数据适配器

}

@Override

@SuppressWarnings("unchecked")

}

}

4、云端数据的查询和listview点击查看界面（XML略）
