How to change two button images when clicking one in Android?

Question

I am creating an Android, java-based Minesweeper knock-off for a college project.

Right now, I can't find how to set two buttons to pressed state and make them both revert to not-pressed again after releasing the click (more specifically the "emoticon button", when pressing one of the 1, 2, blank or mine buttons). That's what I mean: Screenshot.

I tried setting the Smile button to pressed state with: buttonEmotikon.setPressed(!buttonEmotikon.isActivated()); and <item android:state_pressed="true" android:drawable="@drawable/wow"/> in the xml, but it doesn't change back to primary image after the onClick instruction.

This is the full xml file for smile button:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
          android:drawable="@drawable/wow"/>
    <item android:state_activated="true">
        <bitmap android:src="@drawable/sad"/>
    </item>
    <item android:state_first="true" android:drawable="@drawable/smile2"/>
    <item android:drawable="@drawable/smile2"/>
</selector>

This is an excerpt of the layout with smile button and generic grey button (which is the same as the rest):

`<ImageButton
            android:layout_width="47dp"
            android:layout_height="47dp" app:srcCompat="@drawable/block"
            android:id="@+id/imageButton25"
            app:layout_constraintEnd_toEndOf="parent" android:layout_marginEnd="52dp"
            android:layout_marginTop="4dp" app:layout_constraintTop_toBottomOf="@+id/imageButton20"
            android:layout_marginBottom="8dp" app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintVertical_bias="0.0" app:layout_constraintStart_toEndOf="@+id/imageButton24"
            android:layout_marginStart="3dp" app:layout_constraintHorizontal_bias="0.0"
            android:src="@drawable/field_bomb" tools:ignore="RtlCompat"/>
    <ImageButton
            android:layout_width="49dp"
            android:layout_height="49dp" app:srcCompat="@drawable/smile2"
            android:id="@+id/buttonEmotikon" app:layout_constraintStart_toStartOf="parent"
            android:layout_marginStart="8dp" app:layout_constraintEnd_toEndOf="parent" android:layout_marginEnd="8dp"
            android:layout_marginTop="60dp" app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintHorizontal_bias="0.488" app:layout_constraintBottom_toBottomOf="@+id/imageView"
            app:layout_constraintVertical_bias="0.019" android:src="@drawable/emotikon" tools:ignore="RtlCompat"/>`

My onClick method looks like:

`@Override
    public void onClick(View v){
        Intent intent;
        v.setActivated(!v.isActivated());
        v.setEnabled(false);
        switch (v.getId()) {
            case R.id.buttonEmotikon:

` and there are cases with different button ids. All clickable objects are ImageButtons.

Thanks in advance.

Thank you for the answer. I've updated the first post with more code. — phiel, Jan 13 '20 at 22:19

You should use selector as background of ToggleButton and place your images in proper states like in this answer

To change the image to the boolean value of isActivated, add the following code:

<item android:state_activated="false">
    <bitmap android:src="@drawable/smile2"/>
</item>
