Android SDK 2.0以上读取手机联系人

具体读取联系人及号码，以ListView方式显示，代码如下。

public class ReadContacts extends Activity {

ListView listView;

ListAdapter adapter;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

LinearLayout linearLayout = new LinearLayout(this);

linearLayout.setOrientation(LinearLayout.VERTICAL);

linearLayout.setBackgroundColor(Color.BLACK);

LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(

LinearLayout.LayoutParams.FILL_PARENT,

LinearLayout.LayoutParams.WRAP_CONTENT);

listView = new ListView(this);

listView.setBackgroundColor(Color.BLACK);

linearLayout.addView(listView, param);

this.setContentView(linearLayout);

// 生成动态数组，加入数据

ArrayList> listItem = new ArrayList>();

ArrayList> listItemRead= newArrayList>();

Cursor cursor = getContentResolver().query(

ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

while(cursor.moveToNext()) {

HashMap map = new HashMap();

String phoneName = cursor.getString(cursor

.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

map.put("ItemTitle", phoneName);// 电话姓名

String contactId = cursor.getString(cursor

.getColumnIndex(ContactsContract.Contacts._ID));

String hasPhone = cursor

.getString(cursor

.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

if(hasPhone.compareTo("1") == 0) {

Cursor phones = getContentResolver().query(

ContactsContract.CommonDataKinds.Phone.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.Phone.CONTACT_ID

+ " = " + contactId, null, null);

while(phones.moveToNext()) {

String phoneNumber = phones

.getString(phones

.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

String phoneTpye = phones

.getString(phones

.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));

map.put("ItemText", phoneNumber); // 多个号码如何处理

}

phones.close();

}

listItem.add(map);

}

// 生成适配器的Item和动态数组对应的元素

SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItem,// 数据源

android.R.layout.simple_list_item_2,// ListItem的XML实现

// 动态数组与ImageItem对应的子项

new String[] { "ItemTitle", "ItemText" },

new int[] { android.R.id.text1, android.R.id.text2 });

listView.setAdapter(listItemAdapter);

cursor.close();

}

}
