Android----------Recyclerview设置点击事件

OkHttp网络请求依赖：

compile 'com.squareup.okhttp3:okhttp:3.8.1'

RecyclerView依赖：

compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'

XRecyclerView依赖：

compile 'com.jcodecraeer:xrecyclerview:1.3.2'

1.适配器中

public class Myadapter extends RecyclerView.Adapter {
private View view;
private Context mcontext;
private ArrayList<News.DataBean> mlist=new ArrayList<>();
private OnItemClickListener mClickListener;

public Myadapter(Context mcontext,ArrayList<News.DataBean> list)

{
this.mcontext = mcontext;
this.mlist=list;
}

//找到需要导入的布局
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
view = LayoutInflater.from(mcontext).inflate(R.layout.item, null);
return new ViewHolder(view,mClickListener);

}
//加载相应的内容
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
ViewHolder viewholder=(ViewHolder)holder;
viewholder.age.setText(""+getItem(position).getUserAge());
viewholder.work.setText(""+getItem(position).getOccupation());
viewholder.introduction.setText(""+getItem(position).getIntroduction());
Glide.with(mcontext).load(getItem(position).getImg()).into(viewholder.ima);
}

//手写的重置数据的方法
public void setdata(ArrayList<News.DataBean> list){
if (list!=null&&list.size()>0){
mlist.addAll(list);
}

}
//手写的获得视图的方法
public News.DataBean getItem(int position){
return mlist.get(position);

};

@Override
public int getItemCount() {
return mlist.size();
}

//定义的ViewHolder类继承RecyclerView.ViewHolder 并找到布局中的ID
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
private OnItemClickListener mListener;// 声明自定义的接口
private TextView age,work,introduction;
private ImageView ima;
public ViewHolder(View itemView,OnItemClickListener  listener) {
super(itemView);
mListener=listener;
//给item设置点击事件
itemView.setOnClickListener(this);

age=(TextView)itemView.findViewById(R.id.age);
work=(TextView)itemView.findViewById(R.id.work);
introduction=(TextView)itemView.findViewById(R.id.introduction);
ima=(ImageView)itemView.findViewById(R.id.image);
}

@Override
public void onClick(View v) {
// getpostion()为Viewholder自带的一个方法，用来获取RecyclerView当前的位置，将此作为参数，传出去
mListener.onItemClick(v,getPosition());

}
}
//手写的一个接口
public interface OnItemClickListener {
public void onItemClick(View view, int postion);
}
//自定义的方法
public void setOnItemClickListener(OnItemClickListener listener){
this.mClickListener=listener;
}
}

2.在需要设置点击事件的页面内

//Recyclerview的点击事件

md.setOnItemClickListener(new Myadapter.OnItemClickListener() {
@Override
public void onItemClick(View view, int postion) {
Toast.makeText(MainActivity.this, mlist.get(postion).getIntroduction(), Toast.LENGTH_SHORT).show();
}
});

----------------------------------------------------------------------------------------------------------------------------------------------------

加一个点，就是Recyclerview滑动到底部加载更多

注：a为链接URL最后的page数

  initdata()为网络请求的方法

          mrv为Recyclerview的变量名

//下拉加载更多
mrv.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
LinearLayoutManager lm = (LinearLayoutManager) mrv.getLayoutManager();
int totalItemCount = recyclerView.getAdapter().getItemCount();
int lastVisibleItemPosition = lm.findLastVisibleItemPosition();
int visibleItemCount = recyclerView.getChildCount();
if (newState==mrv.SCROLL_STATE_IDLE&& lastVisibleItemPosition == totalItemCount - 1 && visibleItemCount > 0){
//加载更多
a++;
initdata();

}
}
});
