下拉刷新+Recycle+上拉刷新

下拉刷新：

activity中：

public class DemoBActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener{

@BindView(R.id.demo_b_recyclerview)RecyclerView recyclerView;
@BindView(R.id.swipeRefreshLayout)SwipeRefreshLayout swipeRefreshLayout;
private SimpleAdapter simpleAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_demo_b);
ButterKnife.bind(this);
//设置布局
recyclerView.setLayoutManager(new LinearLayoutManager(this));
simpleAdapter = new SimpleAdapter();
recyclerView.setAdapter(simpleAdapter);

//下拉刷新监听
swipeRefreshLayout.setOnRefreshListener(this);
}

@Override
public void onRefresh() {
//刷新3秒后，展示20条新数据
new Thread(new Runnable() {
@Override
public void run() {
//沉睡3秒
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
simpleAdapter.clear();//刷新数据，清空旧数据
for (int i = 0; i < 20; i++) {
simpleAdapter.addItem("我是新刷新到的第" + i + "条数据");
}
//更新UI（需要在UI线程）
runOnUiThread(new Runnable() {
@Override
public void run() {
simpleAdapter.notifyDataSetChanged();
//刷新完成，关闭progressbar
swipeRefreshLayout.setRefreshing(false);
}
});
}
}).start();
}
}

adapter中实现对recycleView的setAdapter(●ˇ∀ˇ●)

package com.fuicuiedu.xc.resourceviewdemo_20170321;

import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import java.util.ArrayList;

import butterknife.BindView;
import butterknife.ButterKnife;

/**

*/

public class SimpleAdapter extends RecyclerView.Adapter<SimpleAdapter.DemoViewHolder>{

private ArrayList<String> datas = new ArrayList<>();

//添加数据
public void addItem(String data){
datas.add(data);
}
//清空数据
public void clear(){
datas.clear();
}

//创建
@Override
public DemoViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//把item视图注入进来
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_text,parent,false);
return new DemoViewHolder(view);
}

//绑定数据
@Override
public void onBindViewHolder(DemoViewHolder holder, int position) {
//拿到数据
String data = datas.get(position);
//拿到当前项的视图
TextView textView = holder.textView;
//绑定数据
textView.setText(data);
}

//获取item数量
@Override
public int getItemCount() {
return datas.size();
}

//先实现ViewHolder
static class DemoViewHolder extends RecyclerView.ViewHolder{
@BindView(R.id.textView)TextView textView;

public DemoViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this,itemView);
}
}
}

布局：

=======================上拉刷新=使用第三方控件需要依赖===============

mugen的机制：监视recycleView是否滑动到底部，滑到底部，自动加载更多数据（onLoadMore方法）

 

package com.fuicuiedu.xc.resourceviewdemo_20170321.democ;

import android.support.v4.widget.SwipeRefreshLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;

import android.view.View;
import android.widget.ProgressBar;

import com.fuicuiedu.xc.resourceviewdemo_20170321.R;
import com.fuicuiedu.xc.resourceviewdemo_20170321.SimpleAdapter;
import com.mugen.Mugen;
import com.mugen.MugenCallbacks;

import butterknife.BindView;
import butterknife.ButterKnife;

public class DemoCActivity extends AppCompatActivity implements
SwipeRefreshLayout.OnRefreshListener,
MugenCallbacks{

@BindView(R.id.demo_c_rv)RecyclerView recyclerView;
@BindView(R.id.demo_c_srl)SwipeRefreshLayout swipeRefreshLayout;
@BindView(R.id.demo_c_prb)ProgressBar progressBar;
private SimpleAdapter simpleAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_demo_c);
ButterKnife.bind(this);

recyclerView.setLayoutManager(new LinearLayoutManager(this));
simpleAdapter = new SimpleAdapter();
recyclerView.setAdapter(simpleAdapter);

//下拉刷新
swipeRefreshLayout.setOnRefreshListener(this);

//上拉加载（mugen）,（会检测到列表是否滑动到底部，如果到了底部执行“onLoadMore”）
Mugen.with(recyclerView,this).start();
}

@Override
public void onRefresh() {
//刷新3秒后，展示20条新数据
new Thread(new Runnable() {
@Override
public void run() {
//沉睡3秒
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
simpleAdapter.clear();//刷新数据，清空旧数据
for (int i = 0; i < 20; i++) {
simpleAdapter.addItem("我是新刷新到的第" + i + "条数据");
}
//更新UI（需要在UI线程）
runOnUiThread(new Runnable() {
@Override
public void run() {
simpleAdapter.notifyDataSetChanged();
//刷新完成，关闭progressbar
swipeRefreshLayout.setRefreshing(false);
}
});
}
}).start();
}

// ------------------- Mugen回调 ------------------
//加载数据时的逻辑
@Override
public void onLoadMore() {
//显示加载布局
progressBar.setVisibility(View.VISIBLE);
//上拉1.5秒后，加载10条数据
new Thread(new Runnable() {
@Override
public void run() {
//沉睡1.5秒
try {
Thread.sleep(1500);
} catch (InterruptedException e) {
e.printStackTrace();
}
//加载10条新数据
for (int i = 0; i < 10; i++) {
simpleAdapter.addItem("我是新加载到的第" + i + "条数据");
}
//加载完成,更新UI
runOnUiThread(new Runnable() {
@Override
public void run() {
simpleAdapter.notifyDataSetChanged();
//隐藏加载prb
progressBar.setVisibility(View.GONE);
}
});

}
}).start();
}

//加载状态
@Override
public boolean isLoading() {
//判断prb显示状态
return progressBar.getVisibility() == View.VISIBLE;
}

//是否加载完所有数据
// （如果返回true，则列表滑动到底部时，不再执行onLoadMore）
// 如果返回false，列表滑动到底部时，执行onLoadMore
@Override
public boolean hasLoadedAllItems() {
return false;
}
}
