android 取得电话本中用户信息

本程序主要是实现当用户点击按钮时开启电话本,并从电话本中返回用户信息给该程序

界面xml,比较简单,只有一个按钮和两个EditText

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
<EditText 
    android:id="@+id/show"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:cursorVisible="false"/>
<EditText 
    android:id="@+id/phone"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:cursorVisible="false"/>
<Button 
    android:id="@+id/bn"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="showContacts"/>
</LinearLayout>

下面是java 文件，主activity

package com.happyrxk.contact
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

    //定义出启动activity所用的请求码
    final int PICK_CONTACT = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button bn = (Button)findViewById(R.id.bn);
        bn.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent();
                //这里设置intent的action与type，对应的就是android的电话本程序
                intent.setAction(Intent.ACTION_GET_CONTENT);
                intent.setType("vnd.android.cursor.item/phone");
                startActivityForResult(intent, PICK_CONTACT);
            }
        });
    }

    

    //复写此方法,对应的是startActivityForResult
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
        case PICK_CONTACT:
            if(resultCode == Activity.RESULT_OK){
                //取得返回的数据
                Uri contactData = data.getData();
                //根据返回的数据获得数据游标
                Cursor cursor = getContentResolver().query(contactData, null, null, null, null);
                if(cursor.moveToFirst()){
                    String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                    String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
                    String phoneNumber = null;
                    System.out.println(contactId+"");
                    //获得id为contactId的游标并取得手机号码  TYPE_MOBILE指的手机号，还有TYPE_HOME等
                    Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID+"="+contactId + " AND " + ContactsContract.CommonDataKinds.Phone.TYPE + "=" + ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null, null);

                    if(phones.moveToFirst()){
                        phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        System.out.println("pnumber1  "+phoneNumber);
                    }
                    System.out.println("pnumber  "+phoneNumber);
                    //phones.close();
                    EditText show = (EditText)findViewById(R.id.show);
                    show.setText(name);
                    EditText phone = (EditText)findViewById(R.id.phone);
                    phone.setText(phoneNumber);
                }
                cursor.close();
            }
            break;

        default:
            break;
        }
    }



    @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;
    }
    
}

进行此操作需要在MainFest声明权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>
