There must be something wrong, visibility = gone will/should not create that space in between — D Agrawal, Apr 08 '16 at 05:08
setVisibility is GONE is working fine, but there is space between items please look at image two. — Sarath Kumar, Apr 08 '16 at 05:10
Which view did you change visibility? it should be `CardView.setVisibility()`, not the inner FrameLayout — sakiM, Apr 08 '16 at 05:10
Have you used the same xml, if yes then where is the id assigned to cardview ? its assigned to framelayout. Change it — D Agrawal, Apr 08 '16 at 05:15

Check your Margin buddy, It says 2dp top and 2dp Bottom so second cardview will have total 4dp margin 2dp of bottom from 1st cardview and 2dp top margin of 2nd cardview . Hope that Helps — Deep Dave, Apr 08 '16 at 06:26

Use setVisibility gone , use this and yes remove extra margin you have given

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/cardview3"
    android:layout_width="match_parent"
    android:layout_height="126dp"
    android:layout_marginLeft="8.00dp"
    android:layout_marginRight="8.00dp"
    android:background="@color/white"
    app:cardCornerRadius="2dp"
    app:cardElevation="0dp"
    app:cardMaxElevation="0dp"
    app:cardPreventCornerOverlap="true"
    app:cardUseCompatPadding="true">

    <FrameLayout
        android:id="@+id/container3"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</android.support.v7.widget.CardView>

example

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.stackone);

        final TextView textView1 = (TextView) findViewById(R.id.text1);
        final TextView textView2 = (TextView) findViewById(R.id.text2);
        final TextView textView3 = (TextView) findViewById(R.id.text3);

        final CardView cardView1 = (CardView) findViewById(R.id.cardView1);
        final CardView cardView2 = (CardView) findViewById(R.id.cardView2);
        final CardView cardView3 = (CardView) findViewById(R.id.cardView3);

        textView1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                textView2.setVisibility(View.GONE);   //visibility gone for cardview textview

                LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                    LinearLayout.LayoutParams.MATCH_PARENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT
                );
                params.setMargins(10, -5, 10, 10);//set your margin here
                cardView3.setLayoutParams(params);

                cardView3.setCardElevation(5);
            }
        });
    }

Use gone and visible types of viewHolder. Where gone viewholder has height="0dp".

BaseRecyclerViewAdapter.java

public class BaseRecyclerViewAdapter extends RecyclerView.Adapter<BaseRecyclerViewAdapter.ViewHolder> {

private final int TYPE_GONE = 0;
private final int TYPE_VISIBLE = 1;
private int gonePosition;

@Override
public int getItemViewType(int position) {
    return position == gonePosition ? TYPE_GONE : TYPE_VISIBLE;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    final LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    if (viewType == TYPE_VISIBLE){
        return new ViewHolder(inflater.inflate(R.layout.item_card_visible, parent, false));
    }else {
        return new ViewHolder(inflater.inflate(R.layout.item_card_gone, parent, false));
    }
}

public void setGonePosition(int gonePosition) {
    this.gonePosition = gonePosition;
}

item_card_visible.xml

 <android.support.v7.widget.CardView 
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="200dp">

</android.support.v7.widget.CardView>

item_card_gone.xml

<android.support.v7.widget.CardView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="0dp"
    android:layout_height="0dp">

</android.support.v7.widget.CardView>

usage

adapter.setGonePosition(...);
adapter.notifyDataSetChanged();

optimization

Remember last hidden position, and use notifyItemChanged

public void setGonePosition(int gonePosition) {
    final int oldGonePosition = this.gonePosition;
    this.gonePosition = gonePosition;

    if (oldGonePosition != -1){
        notifyItemChanged(oldGonePosition);
    }
    notifyItemChanged(gonePosition);
}
