我希望我的卡可以彼此对齐,但是它们会产生额外的空间,我不知道该如何解决。 我以为是recycleView的问题。
//My RVadapter
public class RVAdapter extends RecyclerView.Adapter<RVAdapter.PersonViewHolder>{
List<Bus> abstractlistbus;
public static class PersonViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView bus_name;
TextView controller_Status;
Context mContext;
PersonViewHolder(final View itemView, final Context context) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.cv);
mContext=context;
bus_name = (TextView)itemView.findViewById(R.id.name);
controller_Status = (TextView)itemView.findViewById(R.id.Status);
}
}
RVAdapter(List<Bus> abstractlist){
this.abstractlistbus = abstractlist;
}
@Override
public int getItemCount() {
return abstractlistbus.size();
}
@Override
public PersonViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.cards_layout, viewGroup, false);
PersonViewHolder pvh = new PersonViewHolder(v,v.getContext());
return pvh;
}
@Override
public void onBindViewHolder(/*final*/ PersonViewHolder personViewHolder, final int i) {
personViewHolder.bus_name.setText("Номер автобуса:"+abstractlistbus.get(i).number);
personViewHolder.controller_Status.setText(abstractlistbus.get(i).controller+"");
}
}

in your card linear layout make **android:layout_height="match_parent"** to **android:layout_height="wrap_content"**
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:tag="cards main container">

在您的cards_layout.xml中-将这些边距添加到线性布局中。
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
这将解决您的问题。
