一.摘要:利用內容解釋器調用聯系人應用的內容提供者暴露的方法,讀取聯系人信息.(本節只總結實現步驟,解釋請看http://www.xuanyusong.com/archives/169)

?

二.主要邏輯:

1.獲取內容解釋者mResolver

ContentResolver mResolver=getApplicationContext().getContentResolver();

2.調用解釋者的query方法獲取cursor

Cursor cursor=mResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection,null,null,null);

3.遍歷cursor獲得聯系人信息

if(cursor!=null){while(cursor.moveToNext()){...... }}

?

三.具體實現:

?

AndroidManifest需要加入權限:

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

?

MainActivity.java

public class MainActivity extends AppCompatActivity {String[] projection=new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID,ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,ContactsContract.CommonDataKinds.Phone.NUMBER};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);List<Contract> mContracts=new ArrayList<Contract>();mContracts=getcontract();if(mContracts!=null){for (Contract contract:mContracts) {int id=contract.getId();String name=contract.getName();String phone=contract.getPhone();System.out.println(id+name+phone);}}}private List<Contract> getcontract(){List<Contract> contracts=new ArrayList<Contract>();ContentResolver mResolver=getApplicationContext().getContentResolver();Cursor cursor=mResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection,null,null,null);if(cursor!=null){while(cursor.moveToNext()){String phone =cursor.getString(2);int id=cursor.getInt(0);String name=cursor.getString(1);Contract contract=new Contract();contract.setId(id);contract.setName(name);contract.setPhone(phone);contracts.add(contract);}}return contracts;} }

?

Contract.java

public class Contract {int id=0;String name=null;String phone=null;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}public int getId() {return id;}public void setId(int id) {this.id = id;}}
