安卓读取通讯录数据

本文主要讲点击“从通讯录添加”跳转到系统的通讯录，点击其中一条通讯录返回界面并读取数据：姓名+号码。

   /*跳转到系统通讯录里获取号码*/
    private void addNumber() {
        startActivityForResult(new Intent(
                Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI), 1);
    }

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 1) {
            ContentResolver reContentResolverol = getContentResolver();
            Uri contactData = data.getData();
            @SuppressWarnings("deprecation")
            Cursor cursor = managedQuery(contactData, null, null, null, null);
            cursor.moveToFirst();
            String username = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            Cursor phone = reContentResolverol.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId,
                    null,
                    null);
            while (phone.moveToNext()) {

                Logs.i("用户名：" + username + "   电话号码：" + usernumber + "  id:  " + contactId);
                et.setText(usernumber.replace(" ", ""));
