Question

我在recyclerView中遇到问题，它没有显示可绘制资源中的图像。

我已经将imageResource与其他text和audioResource存储在数据类中，然后使用适配器填充recyclerView。一切正常，如正确显示文本，播放音频，仅图像视图未显示图像，而是显示紫色框。

这是数据类

    @Parcelize
    data class Word (
       // English Translation of word
       var englishTranslation: String,
       // French Translation of word
       var frenchTranslation: String,
       // Image resource for corresponding image to the word
       var imageResourceId: Int,
       // Audio resource for the pronunciation of the word
       var audioResourceId: Int,
       // String for description of image
       var imageContentDescription: String,
       // String for description of audio
       var audioResourceContentDescription: String): Parcelable

这是实际的列表数据

    private val fruits: MutableList<Word> = mutableListOf(
        Word("Apple", "Pomme",
            R.drawable.ic_image_apple, R.raw.des_fruits, "Image of the apple",
            "pronunciation of the audio"),
        Word("Orange", "Orange",
            R.drawable.ic_image_apple, R.raw.des_fruits, "image of the Orange",
            "Plays the pronunciation audio"),
        Word("Strawberry", "Fraise",
            R.drawable.ic_image_apple, R.raw.des_fruits, "image of the Strawberry",
            "Plays the pronunciation audio")
    )

及以下是recyclerView项目布局中imageView的xml代码

    <ImageView
        android:id="@+id/word_image"
        android:layout_width="36dp"
        android:layout_height="36dp"
        android:layout_marginStart="@dimen/spacing_large"
        android:layout_marginTop="8dp"
        android:layout_marginBottom="8dp"
        android:contentDescription="@{word.imageContentDescription}"
        android:src="@{word.imageResourceId}"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:src="@drawable/ic_image_apple" />
