调用系统应用选择联系人并返回联系人信息

实现步骤:

用startActivityForResult的方式启动Intent
onActivityResult获取返回的Uri信息
根据Uri查询联系人信息

简单演示(因为是真机演示,所以截走了联系人的界面)

这里写图片描述

1.启动联系人选择:

 Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); //REQUEST_CODE为自定义的请求码startActivityForResult(intent, REQUEST_CODE);

2.获取返回的Uri

 @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        if (requestCode == REQUEST_CODE) {            if (resultCode == RESULT_OK) {                Uri uri = data.getData();                Cursor cursor = managedQuery(uri, null, null, null, null);                //查询联系人姓名的方法                String contactName = getContactName(cursor);                //查询联系人电话的方法                String contactNumber = getContactNumbler(cursor);        }    }

3.根据uri查询联系人信息

获取联系人姓名:

private String getContactName(Cursor cursor) {        cursor.moveToFirst();        String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));        return name;    }

获取联系人电话:

 private String getContactNumbler(Cursor cursor) {        StringBuilder builder = new StringBuilder();        //获取所选联系人的电话的个数        int count = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));        if (count > 0) { // 存在电话            //获取联系人的id            int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));            //根据id查询电话            Cursor phoneCursor = managedQuery(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + id, null, null);            if (phoneCursor.moveToFirst()) {                String numbler = "";                do {                    numbler = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                    builder.append(numbler+"\n");                } while (phoneCursor.moveToNext());            }        }        return builder.toString();    }
