在浮動操作按鈕旁邊添加標簽

Question

我正在嘗試在每個元素中帶有標簽app:fab_label 的浮動操作按鈕旁邊添加一個標簽，但它沒有顯示。 這是我的代碼：

    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView

        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:pressedTranslationZ="12dp" />

</androidx.constraintlayout.widget.ConstraintLayout>

這是因為我使用了簽名com.google.android.material.floatingactionbutton.FloatingActionButton而不是以 android... 開頭的標准簽名嗎？

只需將其更改為 android:text 並將您的字符串放在那里..如果這不能解決您的問題，請使用擴展浮動操作按鈕，您可以使用 android:text 屬性設置文本
