Android 选择通讯录联系人回显

　　1.启动系统选择联系人界面

　　Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);

　　startActivityForResult(intent, 0);

　　2.重写OnActivityResult方法获取数据

　　@Override
　　public void onActivityResult(int requestCode, int resultCode, Intent data) {
       super.onActivityResult(requestCode, resultCode, data);
           if(data!=null){
              switch (requestCode)  
           {  
         　　case 0:
           　　 Uri conatctData  = data.getData();
            　　Cursor cursor = managedQuery(conatctData, null, null, null, null);
            　　if (cursor.moveToFirst()) {
               　　String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
               　　String names = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)) ;
               　　Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +"="+contactId, null, null);
               　　String phonenum="";
               if (phones.moveToFirst()) {
                  phonenum = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
               }
               name.setText(names);
               phone.setText(phonenum);
               if (Build.VERSION.SDK_INT <14) {
                  phones.close();
               }
            }
            if (Build.VERSION.SDK_INT <14) {//不添加的话Android4.0以上系统运行会报错
               cursor.close();
            }
            break;
         }

       }
       
　　}

　　3.添加权限

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