Hey fellow programmers,
I was just programming in a listView and implementing actions for tapping a list element until I got to a point where I wanted to keep things recursively. Taken this ClickListener, I would like to have the image next to the list element changed when tapped.
list.add(Model("firstelement","description 1", R.drawable.button_activated))
list.add(Model("secondelement","description 2",R.drawable.button_activated))
listview.adapter = MyAdapter(this, R.layout.row, list)
var elementArray: IntArray = intArrayOf(0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0)
listview.setOnItemClickListener{ parent: AdapterView<*>, view: View, position:Int, id: Long ->
val currentimage = ? //here I'd like to retrieve the imageview of the tapped list item
val img: ImageView = findViewById(R.id.currentimage)
if (elementArray.get(position)==0){
img.setImageResource(R.drawable.button_activated)
elementArray.set(position,1)
}
else if (elementArray.get(position)==1){
img.setImageResource(R.drawable.button_dectivated)
elementArray.set(position,0)
The images are added to the list together with the text view. How can I retrieve them to change them? Tried listview.getItemIdAtPosition but that leads to errors.
I bet there is a way - I just don't see it. Thanks in advance for any hint!
In addition, here is my layout row.xml where the list gets loaded into:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
>
<ImageView
android:layout_width="75dp"
android:layout_height="75dp"
android:id="@+id/image0"
android:src="@mipmap/ic_launcher"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/textView1"
android:text="first element"
android:textStyle="bold"
android:textSize="20sp"
android:layout_margin="5dp"
android:textColor="#000"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView2"
android:text="second element"
android:textSize="18sp"
android:layout_margin="5dp"
android:textColor="#a9a9a9"
/>
</LinearLayout>
</LinearLayout>
