The first picture comes out. When I slide the screen, the 2nd picture comes out and then crashes.

The imageView.setImageResource(img[position]); line shows an error.

You are using big images size on

int[] img = {R.drawable.foraritdizi1,R.drawable.forbaginti,R.drawable.forbasit1,
            R.drawable.forbinom1,R.drawable.forbolme1,R.drawable.ic_launcher_foreground};

which cause java.lang.OutOfMemoryError. try to reduce those images size and on your manifest add

<application
        android:hardwareAccelerated="true"
        android:largeHeap="true"
        >

The first picture comes out. When I slide the screen, the 2nd picture comes out and then crashes
