An abnormal horizontal ListView-like pile layout.
The following pictures were captured earlier. Since the source code and the outputted-apk have changed some params, you will have a different UI when you directly run the code or install the apk file. Hope there has no confusions later.
Recently I have seen this kind of UI design, and at the first sight I was trying to implement it by using RecyclerView's LayoutManager. Unfortunately, I am unable to contrust a clear Math model while sliding the PileView. After several tries, I gave up LayoutManager, and find another way for this implementation. If you make LayoutManager works well for this UI design, please tell me later.
- declare PileLayout in your xml file
<com.stone.pile.libs.PileLayout
android:id="@+id/pileLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="5dp"
android:paddingTop="5dp"
pile:displayCount="1.5"
pile:interval="10dp"
pile:scaleStep="0.22"
pile:widthHeightRate="1.22" />Meanwhile, pileLayout is able to be customized by these 4 params:
| name | format | description |
|---|---|---|
| interval | dimension | items-margin each other |
| sizeRatio | float | each item's height/witdth |
| scaleStep | float | size scale step when needed |
| displayCount | float | number of items that may display |
- in Java files:
pileLayout = (PileLayout) findViewById(R.id.pileLayout);
pileLayout.setAdapter(new PileLayout.Adapter() {
@Override
public int getLayoutId() {
// item's layout resource id
return R.layout.item_layout;
}
@Override
public void bindView(View view, int position) {
ViewHolder viewHolder = (ViewHolder) view.getTag();
if (viewHolder == null) {
viewHolder = new ViewHolder();
viewHolder.imageView = (ImageView) view.findViewById(R.id.imageView);
view.setTag(viewHolder);
}
// recycled view bind new position
}
@Override
public int getItemCount() {
// item count
return dataList.size();
}
@Override
public void displaying(int position) {
// right displaying the left biggest itemView's position
}
@Override
public void onItemClick(View view, int position) {
// on item click
}
