Android - recyclerview item gone 還是會佔空間

重新定義高度即可
class ViewHolder extends RecyclerView.ViewHolder {
ViewHolder(View itemView) {
super(itemView);
}
public void setVisibility(boolean visible) {
RecyclerView.LayoutParams param = (RecyclerView.LayoutParams) itemView.getLayoutParams();
if (visible) {
param.height = LinearLayout.LayoutParams.WRAP_CONTENT;
param.width = LinearLayout.LayoutParams.MATCH_PARENT;
itemView.setVisibility(View.VISIBLE);
} else {
itemView.setVisibility(View.GONE);
param.height = 0;
param.width = 0;
}
itemView.setLayoutParams(param);
}
}
