Android开发---RecyclerView子项点击事件与SwipeRecyclerView外部框架结合
作者:互联网
1.子项点击事件概述
recyclerView作为列表展示,每个item能够做点击事件,比如点开文件夹之类的,在这里主要写两种方法进行item的点击事件,第一种方式是利用监听器事项,第二种方式是利用已经写好的外部框架SwipeRecyclerView
2.监听器实现
在adapter类中可以定义监听器进行实现,在activity中实现点击事件的具体逻辑
Step1:定义监听器和接口
//设置监听器 private OnRecyclerItemClickListener mOnItemClickListener; public void setRecyclerItemClickListener(OnRecyclerItemClickListener listener){ mOnItemClickListener=listener; } public interface OnRecyclerItemClickListener{ void onRecyclerItemClick(int position); }
Step2:在MyViewHolder中设置item点击事件:
public class MyViewHolder extends RecyclerView.ViewHolder { private TextView tv; public MyViewHolder(@NonNull @NotNull View itemView) { super(itemView); tv=itemView.findViewById(R.id.tv1); itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if(mOnItemClickListener==null){ mOnItemClickListener.onRecyclerItemClick(getAdapterPosition()); } } }); } }
Step3:在activity/fragment中实现点击事件的具体逻辑:可以做跳转、输出等等
myrevAdpter.setRecyclerItemClickListener(new MyrevAdpter.OnRecyclerItemClickListener() { @Override public void onRecyclerItemClick(int position) { Log.e("tag1",String.valueOf(position)); } });
利用监听器实现就是这三步就可以啦
3.利用SwipeRecyclerView外部框架实现
Step1:首先进行导包:在build中添加以下代码
implementation 'com.yanzhenjie.recyclerview:x:1.3.2'
Step2:在xml文件中写这里的SwipeRecyclerView
<com.yanzhenjie.recyclerview.SwipeRecyclerView android:id="@+id/rv_resourcemanage" android:layout_width="match_parent" android:layout_height="match_parent"> </com.yanzhenjie.recyclerview.SwipeRecyclerView>
Step3:声明SwipeRecyclerView并找到控件
private SwipeRecyclerView recyclerView; recyclerView =findViewById(R.id.rv_resourcemanage);
Step4:与RecyclerView一致进行设置(这里需要注意的是setAdapter必须在所有关于adapter操作之后执行)
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(MyResourceActivity.this, LinearLayoutManager.VERTICAL, false); recyclerView.setLayoutManager(linearLayoutManager); resourceAdapter = new ResourceAdapter(fileList, MyResourceActivity.this,map_check); recyclerView.setAdapter(resourceAdapter);
Step5:直接调用SwipeRecyclerView中的方法就可以进行子项的点击事件
//可以直接调用swipeRecyclerView框架里面的点击子项、点击长按事件 recyclerView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(View view, int position) { //做点击事件的逻辑 } } }); //长按 recyclerView.setOnItemLongClickListener(new OnItemLongClickListener() { @Override public void onItemLongClick(View view, int position) { //做长按点击事件的逻辑 } });
利用SwipeRecyclerView进行子项的点击和长按点击就是这几步啦
