Invalidate Not Redrawing View On Api 25

I have a custom view that extends LinearLayout. The view looks like progress bar with a little icon that moves on every click. the updating method is : public void setPointerOffset

Solution 1:

setting layout params to "mPointer" semms to fix it.

private void updateSlider() {
    PercentFrameLayout.LayoutParams params = (PercentFrameLayout.LayoutParams) mPointer.getLayoutParams();
    PercentLayoutHelper.PercentLayoutInfo info = params.getPercentLayoutInfo();
    if (mPointerOffset < MIN_OFFSET)
        mPointerOffset = MIN_OFFSET;
    if (mPointerOffset > MAX_OFFSET)
        mPointerOffset = MAX_OFFSET;
    float percent = mPointerOffset * 0.01f;
    info.startMarginPercent = percent;
    mPointer.setLayoutParams(params);
}
