android 重力权限,Java

我有一个像列表一样的recyclerView,当我删除一个项目时,所有其他项目都向上移动,我希望它们向下移动.我正在考虑将重力设置为项目,或反转适配器中的位置,使底部位置为0.

我的适配器(自定义)：

public class AddEventsAdapter extends HFRecyclerViewAdapter {

public AddEventsAdapter(Context context) {

super(context);

}

@Override

public void footerOnVisibleItem() {

}

@Override

public void addData(int position, String item) {

super.addData(position, item);

}

@Override

public ViewHolder onCreateDataItemViewHolder(ViewGroup parent, int viewType) {

View v = LayoutInflater.from(parent.getContext())

.inflate(R.layout.data_item, parent, false);

return new ViewHolder(v);

}

@Override

public void onBindDataItemViewHolder(ViewHolder holder, int position) {

holder.itemTv.setText(getData().get(position));

}

class ViewHolder extends RecyclerView.ViewHolder{

TextView itemTv;

LinearLayout theLayout;

public ViewHolder(View itemView) {

super(itemView);

itemTv = (TextView)itemView.findViewById(R.id.itemTv);

theLayout = (LinearLayout)itemView.findViewById(R.id.layout2);

theLayout.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

removeData(getAdapterPosition());

}

});

}

}

}

实现方式：

AddEventsAdapter myAdapter = new AddEventsAdapter(this);

assert layout != null;

layout.setAdapter(myAdapter);

layout.setLayoutManager(new LinearLayoutManager(this));

View footerView = LayoutInflater.from(this).inflate(R.layout.footer, layout, false);

myAdapter.setFooterView(footerView);

ArrayList data = new ArrayList<>();

for (int i=0; i<8; i++){

data.add(String.format("Item %d", i));

}

myAdapter.setData(data);
