Android SDK 2.0以上读取手机联系人

Android SDK 2.0以上读取手机联系人

Android SDK 2.0以上的版本对联系人相关的API做了很大的调整，因此在使用时与1.6版本的差异也较大。

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<HashMap<String, Object>> listItem = new ArrayList<HashMap<String, Object>>();

       ArrayList<HashMap<String, Object>> listItemRead= newArrayList<HashMap<String, Object>>();

       Cursor cursor = getContentResolver().query(

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

       while(cursor.moveToNext()) {

           HashMap<String, Object> map = new HashMap<String, Object>();

           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();  

    }

}
