Android - How remove unnecessary space between cards in RecyclerVIew?

To remove unnecessary space between cards in a RecyclerView in Android, you can adjust the item decorations. You can set a custom item decoration with a negative margin to eliminate the space between cards. Here's an example:

import android.content.Context; import android.graphics.Rect; import android.view.View; import androidx.annotation.NonNull; import androidx.recyclerview.widget.RecyclerView; public class ItemDecorationExample extends RecyclerView.ItemDecoration { private final int verticalSpacing; public ItemDecorationExample(Context context, int verticalSpacing) { this.verticalSpacing = verticalSpacing; } @Override public void getItemOffsets(@NonNull Rect outRect, @NonNull View view, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) { super.getItemOffsets(outRect, view, parent, state); // Apply negative margin to remove space between cards outRect.bottom = -verticalSpacing; } }

Then, in your RecyclerView adapter or activity, set this item decoration:

// Assuming you have a RecyclerView named recyclerView int spacingInPixels = getResources().getDimensionPixelSize(R.dimen.card_spacing); recyclerView.addItemDecoration(new ItemDecorationExample(this, spacingInPixels));

Make sure to define the card_spacing dimension in your res/values/dimens.xml:

<resources> <dimen name="card_spacing">8dp</dimen> <!-- Adjust the value based on your preference --> </resources>

This example assumes a vertical RecyclerView with cards, and it sets a negative bottom margin to remove the space between the cards. Adjust the values based on your specific layout and design preferences.
