ContactsContract中Contacts，RawContacts和Data关系图解及其实例代码

来源：互联网发布：中学生学什么编程语言编辑：程序博客网时间：2024/06/16 08:15

（1）Contacts，RawContacts和Data三者之间的关系

Contacts，RawContacts和Data关系图大体如下所示：

（2）三个变量的解释

2.1 ContactsContract.Contacts

Constants for the contacts table, which contains a record per aggregate of raw contacts representing the same person.

2.2 ContactsContract.RawContacts

Constants for the raw contacts table, which contains one row of contact information for each person in each synced account.

2.3 ContactsContract.Data

Constants for the data table, which contains data points tied to a raw contact.

2.4 ContactsContract.CommonDataKinds

Container for definitions of common data types stored in the ContactsContract.Data table.

（3）实例代码

3.1 MainActivity //主菜单Acivity，包括两个按钮：一个用于浏览手机所有联系人信息，另外一个用于添加联系人。

package com.example.contactscontracttest;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

Button viewallcontacts;
Button addcontact;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

viewallcontacts = (Button)findViewById(R.id.viewallcontacts);
addcontact = (Button)findViewById(R.id.addcontact);

viewallcontacts.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(MainActivity.this, ViewAllContactActivity.class);
startActivity(intent);
}
});

addcontact.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(MainActivity.this, AddContactActivity.class);
startActivity(intent);
}
});
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

}

对应的Layout文件activity_main.xml

效果图：

3.2 ViewAllContactActivity //显示手机里所有联系人的信息，由一个ExpandableListView和Button组成。ExpandableListView用于显示一个联系人名称和其所有的电话和Email的联系方式。按钮用于返回主菜单。
