浏览数：20 / 时间：2015年06月11日

一、读取联系人

(1).从raw_contact表读 contact_id

(2).从data表中读取data1

(3).从mimetypes读取mimetype

1.AndroidManifest.xml 添加content权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.writecontact"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />
    <uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_CONTACTS"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

2.MainActivity.java

package com.example.readcontact;

import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
    }
    
    public void click(View view)
    {
        //获取raw_contact表中的数据
        Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
        //获取view_data视图中的数据
        Uri datauri = Uri.parse("content://com.android.contacts/data");
        
        ContentResolver resovler = getContentResolver();
        
        Cursor cursor = resovler.query(uri, null, null, null, null);
        
        while(cursor.moveToNext())
        {
            String id = cursor.getString(cursor.getColumnIndex("contact_id"));
            System.out.println("----------raw_contact start-----------");
            System.out.println("id="+id);
            if(id!=null)
            {
                //注意 这里获取的事data_view视图中的数据  不是data表中的数据
                Cursor dataCursor = resovler.query(datauri, null, "raw_contact_id=?", new String[]{id}, null);
                while(dataCursor.moveToNext())
                {
                    
                    String data = dataCursor.getString(dataCursor.getColumnIndex("data1"));
                    String mimetype = dataCursor.getString(dataCursor.getColumnIndex("mimetype"));
                    System.out.println("data="+data+",mimetype"+mimetype);
                    
                }
                
                dataCursor.close();
            }
            
            
            System.out.println("---------raw_contact end----------");
        }
        cursor.close();
        
    }


}

二、写联系人

1、同读取联系人一样添加权限

2、MainActivity.java

package com.example.writecontact;

import android.content.ContentResolver;
import android.content.ContentValues;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    
    public void click(View view)
    {
        //获取raw_contact表中的数据
        Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");
        //获取view_data视图中的数据
        Uri datauri = Uri.parse("content://com.android.contacts/data");
        
        ContentResolver resovler = getContentResolver();
        
        Cursor cursor = resovler.query(uri, new String[]{"_id"}, null, null, null);
        cursor.moveToLast();
        int lastId = cursor.getInt(0);
        int contact_id = lastId+1;
        ContentValues values = new ContentValues();
        values.put("contact_id", contact_id);
        //向 raw_contact表中添加数据
        resovler.insert(uri, values);
        
        //向data表中添加phone数据
        ContentValues phoneValues = new ContentValues();
        phoneValues.put("data1", "77777");
        phoneValues.put("mimetype", "vnd.android.cursor.item/phone_v2");
        phoneValues.put("raw_contact_id", contact_id);
        //向 raw_contact表中添加数据
        resovler.insert(datauri, phoneValues);
        
        //向data表中添加name数据
        ContentValues nameValues = new ContentValues();
        nameValues.put("data1", "zhaoqi");
        nameValues.put("mimetype", "vnd.android.cursor.item/name");
        nameValues.put("raw_contact_id", contact_id);
        //向 raw_contact表中添加数据
        resovler.insert(datauri, nameValues);
        
        //向data表中添加phone数据
        ContentValues emailValues = new ContentValues();
        emailValues.put("data1", "[email protected]");
        emailValues.put("mimetype", "vnd.android.cursor.item/email_v2");
        emailValues.put("raw_contact_id", contact_id);
        //向 raw_contact表中添加数据
        resovler.insert(datauri, emailValues);
        
        
        
        
    }

}
