像UI一样具有3D卡堆栈外观的Android Viewpager火种 [英] Android Viewpager tinder like UI with 3D card stack appearance
问题描述
我正在尝试使用ViewPager在android中创建类似于火种的UI.
我看过这个库:https://github.com/kikoso/Swipeable-Cards，但是我想在向右滑动后就能看到前一张卡，因此更喜欢ViewPager.
我正在寻找的特定UI详细信息是:
堆叠图像，并在当前视图下方显示下一个视图的轮廓.我已经能够通过ViewPager.PageTransformer界面实现视图的堆叠，但是我无法获得寻呼机内部后续视图的堆叠轮廓-使该部件具有3d外观的部分 >-就像在这里-堆叠在另一张卡片上的卡片- http://i1.cdnds.net/14/38/300x522/friends-tinder-profiles-ross.jpg
这是我的pageTransform方法
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
if (position < -1) { // [-Infinity,-1)
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 0) { // [-1,0]
// Use the default slide transition when moving to the left page
view.setAlpha(1);
view.setTranslationX(0);
view.setScaleX(1);
view.setScaleY(1);
view.setRotation(90*(position));
} else if (position < 1) { // (0,1]
// Fade the page out.
view.setAlpha(1);
// Counteract the default slide transition
view.setTranslationX(pageWidth * -position);
view.setScaleX(1);
view.setScaleY(1);
} else if (position==1) {
view.setAlpha(1);
// view.setPadding(0,15,0,0);
}
else { // (1,+Infinity]
// This page is way off-screen to the right.
view.setAlpha(0);
}
}
viewPager有可能吗?
这就是我设置它的方式-有点怪异，因为我手动触发了transformPage方法，如我的评论中所述:
Android ViewPager手动调用PageTransformer transformPage
但是，它有效！
@Override
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
if (position < -1) { // [-Infinity,-1)
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 0) { // [-1,0]
// Use the default slide transition when moving to the left page
view.setAlpha(1);
view.setTranslationX(0);
view.setTranslationY(0);
view.setScaleX(1);
view.setScaleY(1);
view.setRotation(90*(position));
} else if (position < 1) { // (0,1]
// Fade the page out.
view.setAlpha(1);
view.setRotation(0);
// Counteract the default slide transition
view.setTranslationX(pageWidth * -position);
view.setTranslationY(50*position);
view.setScaleX(Math.max(0.9f, (1 - position)));
view.setScaleY(Math.max(0.9f, (1 - position)));
CardView cv = (CardView)view.findViewById(R.id.card_view);
cv.setPadding(0,0,0,0);
} else if (position==1) {
view.setAlpha(1);
view.setTranslationX(pageWidth*-position);
view.setTranslationY(50*position);
view.setScaleX(Math.max(0.9f, (1 - position)));
view.setScaleY(Math.max(0.9f, (1 - position)));
}
else { // (1,+Infinity]
// This page is way off-screen to the right.
view.setAlpha(1);
}
}
I'm trying to create a tinder-like UI in android using the ViewPager.
I have looked at this library: https://github.com/kikoso/Swipeable-Cards, but I'd like to be able to see the previous card once I swipe right, hence the preference for a ViewPager.
The specific UI detail I am looking for is:
Stacking of images with the outline of the next view underneath the current view. I have been able to achieve the stacking of views through the ViewPager.PageTransformer interface, but I am unable to get the outline of the stack of the subsequent views inside the pager - the part that gives it a 3d look - like over here - card stacked on top of another card - http://i1.cdnds.net/14/38/300x522/friends-tinder-profiles-ross.jpg
Here is my pageTransform method
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
if (position < -1) { // [-Infinity,-1)
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 0) { // [-1,0]
// Use the default slide transition when moving to the left page
view.setAlpha(1);
view.setTranslationX(0);
view.setScaleX(1);
view.setScaleY(1);
view.setRotation(90*(position));
} else if (position < 1) { // (0,1]
// Fade the page out.
view.setAlpha(1);
// Counteract the default slide transition
view.setTranslationX(pageWidth * -position);
view.setScaleX(1);
view.setScaleY(1);
} else if (position==1) {
view.setAlpha(1);
// view.setPadding(0,15,0,0);
}
else { // (1,+Infinity]
// This page is way off-screen to the right.
view.setAlpha(0);
}
}
Is this possible with the viewPager?
So this was the way that I set it up - its a little hacky because I manually trigger the transformPage method as mentioned in my comment here:
Android ViewPager manually call PageTransformer transformPage
BUT, it works!
@Override
public void transformPage(View view, float position) {
int pageWidth = view.getWidth();
if (position < -1) { // [-Infinity,-1)
// This page is way off-screen to the left.
view.setAlpha(0);
} else if (position <= 0) { // [-1,0]
// Use the default slide transition when moving to the left page
view.setAlpha(1);
view.setTranslationX(0);
view.setTranslationY(0);
view.setScaleX(1);
view.setScaleY(1);
view.setRotation(90*(position));
} else if (position < 1) { // (0,1]
// Fade the page out.
view.setAlpha(1);
view.setRotation(0);
// Counteract the default slide transition
view.setTranslationX(pageWidth * -position);
view.setTranslationY(50*position);
view.setScaleX(Math.max(0.9f, (1 - position)));
view.setScaleY(Math.max(0.9f, (1 - position)));
CardView cv = (CardView)view.findViewById(R.id.card_view);
cv.setPadding(0,0,0,0);
} else if (position==1) {
view.setAlpha(1);
view.setTranslationX(pageWidth*-position);
view.setTranslationY(50*position);
view.setScaleX(Math.max(0.9f, (1 - position)));
view.setScaleY(Math.max(0.9f, (1 - position)));
}
else { // (1,+Infinity]
// This page is way off-screen to the right.
view.setAlpha(1);
}
}
