如果您想知道，这是我的 AndroidManifest.xml 文件

here's my AndroidManifest.xml file if you wondering

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.salonyUser">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
      <meta-data android:name="com.onesignal.NotificationAccentColor.DEFAULT" android:value="0F0F0F" />
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
        android:launchMode="singleTask"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
    </application>

</manifest>

编辑

添加后AndroidManifest.xml

After added AndroidManifest.xml

<meta-data
    android:name="com.google.firebase.messaging.default_notification_icon"
    android:resource="@drawable/ic_stat_onesignal_default" /> // I choose mipmap-xxxhdpi icon size for test. :)

我只是想测试 firebase 元数据是否有效，实际上它有效，我得到了我想要的图标！！有没有人解释一下！

I just was wanted to test if firebase meta-data will work or not and Actually it's work and I got the icon I want!! have anybody explanation to this!

推荐答案

在 NotificationCompat.Builder 中设置图标，使用 .setSmallIcon() 作为较小的图标和 .setLargeIcon() 用于大图标.

Set icon in the NotificationCompat.Builder using .setSmallIcon() for smaller icon and .setLargeIcon() for large icon.
