我遇到了Firebase"registration_ids"的问题.当我从Rest Client发送请求时,我得到了成功的响应.

{"multicast_id":4650719213012935695,"success":2,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1468837777484579%214918aff9fd7ecd"},{"message_id":"0:1468837777484484%214918aff9fd7ecd"}]}

但是当我从我的Android应用程序调用相同的php脚本时,它会在响应中给出错误.(我在Charles Proxy中得到了回复)

"registration_ids" field is not a JSON array

这是我的PHP脚本

function fetchFirebaseTokenUsers($message) {       
    $query = "SELECT token FROM firebase_tokens";
    $fcmRegIds = array();
    if($query_run = mysqli_query($this->con, $query)) {         
        while($query_row = mysqli_fetch_assoc($query_run)) {
            array_push($fcmRegIds, $query_row['token']);
        }
    }

    if(isset($fcmRegIds)) {
        $pushStatus = $this->sendPushNotification($fcmRegIds, $message);
    }
}

function sendPushNotification($registration_ids, $message) {

    ignore_user_abort();
    ob_start();

    $url = 'https://fcm.googleapis.com/fcm/send';

    $fields = array(
        'registration_ids' => $registration_ids,
        'data' => $message,
    );

    define('GOOGLE_API_KEY', 'AIzaSyC.......VdYCoD8A');

    $headers = array(
        'Authorization:key='.GOOGLE_API_KEY,
        'Content-Type: application/json'
    );      

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); …

这是我的代码.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical"
                    android:minHeight="1000dp">

                    xmlns:card_view="http://schemas.android.com/apk/res-auto"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginTop="8dp"
                    android:layout_marginLeft="16dp"
                    android:layout_marginRight="16dp"
                    card_view:cardCornerRadius="2dp"
                    card_view:cardElevation="2dp">

<android.support.v7.widget.CardView
                    xmlns:card_view="http://schemas.android.com/apk/res-auto"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginTop="8dp"
                    android:layout_marginLeft="16dp"
                    android:layout_marginRight="16dp"
                    card_view:cardCornerRadius="2dp"
                    card_view:cardElevation="2dp">
</android.support.v7.widget.CardView>
</LinearLayout>

我在xml中设置了线性布局的minHeight.但我想以编程方式设置它.我在这种线性布局中有两张牌.而且我想设置我的了minHeight两张牌高度的基础上.
