效果展示
滑動效果：
當(dāng)向上滑動左邊或著右邊的view時刻蚯，另一個view也跟著滑動互墓；右邊view可以單獨的左右滑動并帶陰影效果。

1缤谎、我們首先在xml里進(jìn)行布局抒倚，布局如下：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/llMain"

android:layout_height="match_parent"
android:background="#2A2D4F"
android:orientation="horizontal"
tools:context=".tworecycler.TwoRecyActivity">
<android.support.v7.widget.CardView

android:layout_width="@dimen/d120"
android:layout_height="wrap_content"

2、重寫HorizontalScrollView對左右滑動時坷澡，變化的監(jiān)聽
public class SwapScrollView extends HorizontalScrollView {
private ScrollViewListener scrollViewListener = null;
public SwapScrollView(Context context) {
super(context);
}
public SwapScrollView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public SwapScrollView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void setScrollViewListener(ScrollViewListener scrollViewListener) {
this.scrollViewListener = scrollViewListener;
}
@Override
protected void onScrollChanged(int x, int y, int oldx, int oldy) {
super.onScrollChanged(x, y, oldx, oldy);
if (scrollViewListener != null) {
scrollViewListener.onScrollChanged(this, x, y, oldx, oldy);
}
}
public interface ScrollViewListener {
void onScrollChanged(SwapScrollView scrollView, int x, int y, int oldx, int oldy);
}
}
3托呕、代碼的實現(xiàn)：
private void initView() {
mLeftRecycler = findViewById(R.id.left_recycler);
mRightRecycler = findViewById(R.id.right_recycler);
mLeftAdapter = new LeftAdapter(mContractArrayList);
LinearLayoutManager leftllm = new LinearLayoutManager(mContext);
leftllm.setOrientation(LinearLayoutManager.VERTICAL);
mLeftRecycler.addItemDecoration(new DividerItemDecoration(mContext, DividerItemDecoration.VERTICAL));
mLeftRecycler.setLayoutManager(leftllm);
mLeftRecycler.setAdapter(mLeftAdapter);
mLeftRecycler.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {
mRightRecycler.scrollBy(dx, dy); //使右邊recyclerView進(jìn)行聯(lián)動
}
}
});
mRightAdapter = new RightAdapter(mItemsArrayList);
LinearLayoutManager rightllm = new LinearLayoutManager(mContext);
rightllm.setOrientation(LinearLayoutManager.VERTICAL);
mRightRecycler.addItemDecoration(new DividerItemDecoration(mContext, DividerItemDecoration.VERTICAL));
mRightRecycler.setLayoutManager(rightllm);
mRightRecycler.setAdapter(mRightAdapter);
mRightRecycler.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (recyclerView.getScrollState() != RecyclerView.SCROLL_STATE_IDLE) {
mLeftRecycler.scrollBy(dx, dy);//使左邊recyclerView進(jìn)行聯(lián)動
}
}
});
//展示和隱藏陰影
rightScrollView.setScrollViewListener(new SwapScrollView.ScrollViewListener() {
@Override
public void onScrollChanged(SwapScrollView scrollView, int x, int y, int oldx, int oldy) {
if (x != 0) {
cardView.setContentPadding(0, 0, 5, 0);
cardView.setCardElevation(8);
} else {
cardView.setContentPadding(0, 0, 0, 0);
cardView.setCardElevation(0);
}
}
});
}
