Android-recycleview Inside Scrollview

Question

In my activity , I want to put a slideShow above my page and then put recycleview after that, to do so ,I'v written this code in my layout:

Solution 1:

Three steps to do this:

Replace your scrollview with NestedScrollView with layout behaviour set to app:layout_behavior="@string/appbar_scrolling_view_behavior"

Keep all your widgets under a linear/relative layout(because nested scroll view accepts only one child) 3.create CustomLinearLayoutManager.java with this code:

publicclassCustomLinearLayoutManagerextendsLinearLayoutManager {

publicCustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout)    {
    super(context, orientation, reverseLayout);
}

privateint[] mMeasuredDimension = newint[2];

@OverridepublicvoidonMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
                      int widthSpec, int heightSpec) {
    finalintwidthMode= View.MeasureSpec.getMode(widthSpec);
    finalintheightMode= View.MeasureSpec.getMode(heightSpec);
    finalintwidthSize= View.MeasureSpec.getSize(widthSpec);
    finalintheightSize= View.MeasureSpec.getSize(heightSpec);
    intwidth=0;
    intheight=0;
    for (inti=0; i < getItemCount(); i++) {
        measureScrapChild(recycler, i,
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                mMeasuredDimension);

        if (getOrientation() == HORIZONTAL) {
            width = width + mMeasuredDimension[0];
            if (i == 0) {
                height = mMeasuredDimension[1];
            }
        } else {
            height = height + mMeasuredDimension[1];
            if (i == 0) {
                width = mMeasuredDimension[0];
            }
        }
    }
    switch (widthMode) {
        case View.MeasureSpec.EXACTLY:
            width = widthSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    switch (heightMode) {
        case View.MeasureSpec.EXACTLY:
            height = heightSize;
        case View.MeasureSpec.AT_MOST:
        case View.MeasureSpec.UNSPECIFIED:
    }

    setMeasuredDimension(width, height);
}

privatevoidmeasureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                               int heightSpec, int[] measuredDimension) {
    Viewview= recycler.getViewForPosition(position);
    if (view != null) {
        RecyclerView.LayoutParamsp= (RecyclerView.LayoutParams) view.getLayoutParams();
        intchildWidthSpec= ViewGroup.getChildMeasureSpec(widthSpec,
                getPaddingLeft() + getPaddingRight(), p.width);
        intchildHeightSpec= ViewGroup.getChildMeasureSpec(heightSpec,
                getPaddingTop() + getPaddingBottom(), p.height);
        view.measure(childWidthSpec, childHeightSpec);
        measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
        measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
        recycler.recycleView(view);
    }
}

}

set adapter to your recyclerview like this:

CustomLinearLayoutManagercustomLinearLayoutManager=newCustomLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
        updatesRecyclerView.setHasFixedSize(true);
        updatesRecyclerView.setLayoutManager(customLinearLayoutManager);
        updatesRecyclerView.setAdapter(yourAdapter);
        updatesRecyclerView.setNestedScrollingEnabled(false);

That's it , it works.
