2、item布局用swipeitemlayout作为根布局，滑动删除的布局也写在布局里面
<?xml version="1.0" encoding="utf-8"?> <com.dengyun.dianshang.pulse.SwipeItemLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="60dp" android:orientation="horizontal"> <LinearLayout android:id="@+id/ll_record" android:layout_width="match_parent" android:layout_height="60dp" android:background="#FFFFFF" android:gravity="center_vertical" android:orientation="horizontal"> <TextView android:id="@+id/tv_checkrecord_time" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:singleLine="true" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="10-30 10:30" android:textColor="#666666" android:textSize="14sp" /> <TextView android:id="@+id/tv_checkrecord_hand" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:text="右手" android:singleLine="true" android:paddingLeft="10dp" android:paddingRight="10dp" android:textColor="#666666" android:textSize="14sp" /> <TextView android:id="@+id/tv_checkrecord_heartrate" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center" android:singleLine="true" android:paddingLeft="10dp" android:paddingRight="10dp" android:text="60" android:textColor="#666666" android:textSize="14sp" /> </LinearLayout> <LinearLayout android:layout_width="wrap_content" android:layout_height="match_parent" android:orientation="horizontal" android:gravity="center_vertical"> <TextView android:id="@+id/tv_item_delete" android:layout_width="75dp" android:layout_height="match_parent" android:background="#ef508d" android:text="删除" android:textSize="15sp" android:textColor="#FFFFFF" android:gravity="center"/> </LinearLayout> </com.dengyun.dianshang.pulse.SwipeItemLayout>
3.代码中设置如下
recyclerView.addOnItemTouchListener(new SwipeItemLayout.OnSwipeItemTouchListener(getActivity())); recyclerView.addItemDecoration(new SpaceItemDecoration(2));
public class SpaceItemDecoration extends RecyclerView.ItemDecoration{ int mSpace; @Override public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) { super.getItemOffsets(outRect, view, parent, state); outRect.left = mSpace; outRect.right = mSpace; outRect.bottom = mSpace; if (parent.getChildAdapterPosition(view) == 0) { outRect.top = mSpace; } } public SpaceItemDecoration(int space) { this.mSpace = space; } }
class RecordAdapter extends RecyclerView.Adapter<RecordAdapter.ViewHolder> { Context mContext; List<CheckRecordBean> mList; RecyclerItemClickListener recyclerItemClickListener; public RecordAdapter(Context mContext, List<CheckRecordBean> mList, RecyclerItemClickListener recyclerItemClickListener) { this.mContext = mContext; this.mList = mList; this.recyclerItemClickListener = recyclerItemClickListener; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view=LayoutInflater.from(mContext).inflate(R.layout.layout_checkrecord_item,parent,false); return new ViewHolder(view); } @Override public void onBindViewHolder(ViewHolder holder, final int position) { holder.tvTime.setText(mList.get(position).time); holder.tvHand.setText(mList.get(position).hand); holder.tvHeartRate.setText(mList.get(position).heartrate); } @Override public int getItemCount() { return mList.size(); } class ViewHolder extends RecyclerView.ViewHolder{ TextView tvTime,tvHand,tvHeartRate,tvDelete; LinearLayout llRecord; public ViewHolder(View itemView) { super(itemView); tvTime=itemView.findViewById(R.id.tv_checkrecord_time); tvHand=itemView.findViewById(R.id.tv_checkrecord_hand); tvHeartRate=itemView.findViewById(R.id.tv_checkrecord_heartrate); tvDelete=itemView.findViewById(R.id.tv_item_delete); tvDelete.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { recyclerItemClickListener.deleteClick(getAdapterPosition()); } }); llRecord=itemView.findViewById(R.id.ll_record); llRecord.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { recyclerItemClickListener.itemClick(getAdapterPosition()); } }); } } }activity实现RecycleritemClickListener接口，完成点击和删除的操作
