Error on showing Toast in ExpandableList child item click

Question

I'm using an ExpandableListView extending BaseExpandableListAdapter in a Fragment and I show it inside a ViewPager. I'm trying to show the Text of each TextView of the childs when I click it. I don't know why it shut down the app when I press a child item. Could someone help me? Thank you a lot!

Here is my Fragment and Adapter:

let placesData = UserDefaults.standard.object(forKey: "places") as? NSData

if let placesData = placesData {
    let placesArray = NSKeyedUnarchiver.unarchiveObject(with: placesData as Data) as? [Place]
    print(placesArray)
}

And here is my layout:

my %CONFIG = (
    'scriptURI' => "data.js",
    'imageFolder' => "images/",
    'outputFileName' => 'testImg.swf',
    'delay' => 3,                       # delay between images
    'fps'   => 10,
    'fadeFrame' => 10                   # 1 second fade in/out
);

sub addImgToMovie {
    my $img = shift;
    my $frameNo = shift;
    my $movie = shift;
    my $movieClip = $movie -> new_mc();
    my $jpeg = $movieClip -> new_jpeg($img);
    $jpeg -> place(Frame => 1);

    my $mc_i = $movieClip -> place(Frame => $frameNo);  

    my $onloadScript = sprintf("
        this._alpha = %d;
        this.apf = %f;
        this.frameIndex = %d;
        this.fadeOutFrameIndex = %d;
        ", 0, 100 / $CONFIG{'fadeFrame'}, 1, $CONFIG{'delay'} * $CONFIG{'fps'} - $CONFIG{'fadeFrame'});
    $mc_i -> onClipEvent('Load') -> compile($onloadScript);

    my $onEnterFrameScript = "
        this.frameIndex += 1;
        if ((this._alpha < 100) && (this.frameIndex < this.fadeOutFrameIndex)) {
            this._alpha += this.apf;
        } else if (this.frameIndex > this.fadeOutFrameIndex) {
            this._alpha -= this.apf;
        }
    ";
    $mc_i -> onClipEvent('EnterFrame') -> compile($onEnterFrameScript);
    return $movie;
}

my $movie = SWF::Builder -> new(
    FrameRate => $CONFIG{'fps'},
    FrameSize => [0, 0, 180, 163],
    BackgroundColor => 'ffffff'
);

my $img = $CONFIG{'imageFolder'} . "adimage1.jpg";
$movie = addImgToMovie($img, 1, $movie);
$movie -> save($CONFIG{'outputFileName'});

EDIT:

Here is the logcat message:

use OnItemClickListener, not CREATE OR REPLACE FUNCTION accdisvalues(thisdate date) RETURNS void AS $BODY$ Update my_table Set mycolumn = true where mydatecol = thisdate; $BODY$ LANGUAGE sql VOLATILE SECURITY DEFINER COST 100; ALTER FUNCTION accdisvalues(date) OWNER TO myconnect;
