Hi I'm developing an app where I'm using viewpager
to make custom animation with viewpager
transformer but the problem is that there is scaling issue with viewpager
page transformer. I tried every possible x and y scaling but still the problem is the same. I'm having hard time understanding the problem please if someone can help me out here.
Below is the image of what I'm trying to achieve
Update:
Well looks I did not find the solution yet but still trying to figure as I'm almost there with just left with the designing of cardstack look.
My page Transformation code
public class CardStackTransformer implements ViewPager.PageTransformer {
private static final float DEFAULT_CURRENT_PAGE_SCALE = 1.0f;
private static final float OTHER_PAGE_SCALE = 0.9f;
private int dimen;
@Override
public void transformPage(@NonNull View view, float position) {
//view.setScaleX(DEFAULT_CURRENT_PAGE_SCALE);
// view.setScaleY(DEFAULT_CURRENT_PAGE_SCALE);
/*dimen = view.getWidth();
int pageWidth = view.getWidth();
final float translateValue = position * -pageWidth;
if (translateValue < -pageWidth) {
view.setTranslationX(translateValue);
}
if (position < -1) {
view.setAlpha(0);
} else if (position <= 0) {
view.setAlpha(1.0f);
view.setTranslationX(view.getWidth() * -position);
view.setTranslationY(0);
view.setScaleX(1);
view.setScaleY(1);
} else if (position <= 1) {
view.setTranslationX(dimen * position);
view.setAlpha(-0.5f * position + 1.0f);
// view.setTranslationX((-dimen / 1.1F) * position);
view.setTranslationX(view.getWidth() * -position);
view.setTranslationY((dimen / 200.09f) * position);
float scaleFactor = OTHER_PAGE_SCALE
+ (1 - OTHER_PAGE_SCALE) * (1 - Math.abs(position));
view.setScaleX(scaleFactor);
view.setScaleY(scaleFactor);
//view.setScaleX(OTHER_PAGE_SCALE);
//view.setScaleY(OTHER_PAGE_SCALE);
} else {
view.setAlpha(0);
}*/
view.setScaleX(DEFAULT_CURRENT_PAGE_SCALE);
view.setScaleY(DEFAULT_CURRENT_PAGE_SCALE);
dimen = view.getWidth();
if(position < -1) {
view.setAlpha(0);
} else if(position <= 0) {
view.setAlpha(1.0f);
view.setTranslationX(0);
view.setTranslationY(0);
view.setScaleX(DEFAULT_CURRENT_PAGE_SCALE);
view.setScaleY(OTHER_PAGE_SCALE);
} else if(position <= 1) {
final float scaleFactor = OTHER_PAGE_SCALE + (1 - OTHER_PAGE_SCALE) * (1 - Math.abs(position));
// view.setTranslationX(dimen * -position);
view.setAlpha(-0.5f * position + 1.0f);
view.setTranslationX((-dimen / 1.1F) * position);
view.setTranslationY((dimen / 209.9f)*position);
view.setTranslationX(view.getWidth() * -position);
view.setScaleX(scaleFactor);
view.setScaleY(scaleFactor);
} else {
view.setAlpha(0);
}
}
}
