    }
    public void setWaktu_keluar(String ket_absensi) {
        this.ket_absensi = ket_absensi;
    }
}

and here is it's API

<?php 
function curl($url){
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    $output = curl_exec($ch); 
    curl_close($ch);      
    return $output;
}
$send = curl("http://hrd.tvip.co.id/rest_server/api/absensi/index?shift_day=2020-08-24&shift_day_2=2020-08-27&badgenumber=0100028400");

// mengubah JSON menjadi array
$data = json_decode($send, TRUE);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

I tried every time but it always blank or no showing data

the main problem is

2020-08-31 10:18:16.245 11130-11130/com.example.eis2 W/System.err: org.json.JSONException: Value <pre>Array of type java.lang.String cannot be converted to JSONObject
android-recyclerview android xml php java

As per your php code you are doing echo <pre>, the same is also coming in output of your api, kindly remove both pre echo statements from your code, use them for debugging your output at php level only.

So in your php code will be like

$data = json_decode($send, TRUE);
echo $data;
