How to make a list of images in a fragment in Kotlin?-CodePudding

I'm new to Kotlin and Android development and I wanted to make a fragment that has a ListView of ImageViews but for some odd reason I get an error that says:

java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

Here is my Fragment.kt code

var array = arrayOf(
        R.drawable.serbia,
        R.drawable.croatia,
        R.drawable.bulgaria,
        R.drawable.azerbejdzan,
        R.drawable.hungari)

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        val context = context as MainActivity

        val lv = context.findViewById(R.id.listview_1) as ListView

        val adapter = ArrayAdapter(context, R.layout.simple_list_item_1, R.id.image1, array)
        lv.adapter = adapter
}

And here is my simple_list_item_1.xml

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@ id/image1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dip"
    tools:ignore="ContentDescription">
</ImageView>

I made this using a list of Strings and a TextView and it works good but I cannot seem to figure how to do it with Images. Any advice?

CodePudding user response：

You should create new CustomAdapter which is extended from BaseAdapter and this adapter should take the array , context as parameters in constructor . You should implement getView method of this adapter and use the layout inside this method. Find imageview from this layout using findViewById method and set image into this component . at the end of method return layout as result . if you have any question , you can ask .Please check this url : https://demonuts.com/android-listview-kotlin/
