Can anyone tell me how to fix the following trace:

W/View    (16810): requestLayout() improperly called by 
theme.effects.TopCenterImageView{41dc73f0 V.ED.... ........ 
0,0-480,690 #7f060066 app:id/normal_image} during second 
layout pass: posting in next frame

Here is the code for TopCenterImageView:

public class TopCenterImageView extends ImageView {

public TopCenterImageView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    setScaleType(ScaleType.MATRIX);
}

public TopCenterImageView(Context context, AttributeSet attrs) {
    super(context, attrs);
    setScaleType(ScaleType.MATRIX);
}

public TopCenterImageView(Context context) {
    super(context);
    setScaleType(ScaleType.MATRIX);
}

@Override
protected boolean setFrame(int l, int t, int r, int b) {
    if (getDrawable() == null) {
        return super.setFrame(l, t, r, b);
    }
    Matrix matrix = getImageMatrix();
    float scaleFactor = getWidth() / (float) getDrawable().getIntrinsicWidth();
    matrix.setScale(scaleFactor, scaleFactor, 0, 0);
    setImageMatrix(matrix);
    return super.setFrame(l, t, r, b);
}

}

Use changed parameter as a change check.

override fun onLayout(changed: Boolean, left: Int, top: Int, right: Int, bottom: Int) {
    super.onLayout(changed, left, top, right, bottom)
    Log.i(TAG, "onLayout: $changed")
    if (changed) {
        changeDefaultView(size)
    }
}

changed is equal to:

TRUE - when the layout CHANGED in comparison with the previous.

FALSE - when the layout DID NOT change in comparison with the previous.
