第一步、先建立一個Contacts.java實體類，用於表示聯絡人。

package com.t20.contacts.entity;

import java.io.Serializable;

public class Contacts implements Serializable {
	//聯絡人姓名
	private String name;
	//聯絡人電話
	private String phone;
	
	public Contacts() {
		super();
	}
	public Contacts(String name, String phone) {
		super();
		this.name = name;
		this.phone = phone;
	}
	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}
	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}
	/**
	 * @return the phone
	 */
	public String getPhone() {
		return phone;
	}
	/**
	 * @param phone the phone to set
	 */
	public void setPhone(String phone) {
		this.phone = phone;
	}
	

 

第二步、在MainActivity.java中，用內容解析器（ContentResolver）獲取聯絡人資訊，並儲存到ListView中

package com.t20.contacts;

import java.util.ArrayList;
import java.util.List;

import com.t20.calendar.R;
import com.t20.contacts.entity.Contacts;

import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.view.View;
import android.view.ViewGroup;
import android.view.Window;
import android.widget.BaseAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends Activity {

	private ListView lv;
	private List<Contacts> conList;
	private MyDapter myDapter;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		//隱藏標題欄，在載入佈局之前設定(相容Android2.3.3版本)
		requestWindowFeature(Window.FEATURE_NO_TITLE);
		setContentView(R.layout.activity_main);
		//列表檢視
		lv=(ListView) findViewById(R.id.listView1);
		//電話薄集合
		conList=new ArrayList<Contacts>();
		
		//1.獲取內容解析器（ContentResolver）
		ContentResolver resolver=getContentResolver();
		//2.定義一個URI（Uniform Resource Identifier 統一資源標示符）
		Uri uri=ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
		//3.查詢
		Cursor cursor=resolver.query(uri, null, null, null, null);
		while (cursor.moveToNext()) {
			String name=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
			String phone=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
			phone=phone.replace("-", "");
			Contacts calendar=new Contacts(name, phone);
			conList.add(calendar);
			
		}
		cursor.close();
		//介面卡
		myDapter=new MyDapter();
		lv.setAdapter(myDapter);
	}

	/**
	 * 自定義一個自配器
	 * @author Administrator
	 *
	 */
	class MyDapter extends BaseAdapter{

		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return conList.size();
		}

		@Override
		public Object getItem(int position) {
			// TODO Auto-generated method stub
			return null;
		}

		@Override
		public long getItemId(int position) {
			// TODO Auto-generated method stub
			return 0;
		}

		@Override
		public View getView(int position, View view, ViewGroup parent) {
			// TODO Auto-generated method stub
			view=View.inflate(MainActivity.this, R.layout.list_item, null);
			//獲取控制元件
			TextView tvName=(TextView) view.findViewById(R.id.tvName);
			TextView tvPhone=(TextView) view.findViewById(R.id.tvPhone);
			//設定控制元件的值
			tvName.setText(conList.get(position).getName());
			tvPhone.setText(conList.get(position).getPhone());
			return view;
		}
		
	}
	
	
}
