RecycleView 上拉刷新,到底部自动加载

Recycle请求到数据后(还没有请求数据的话看上一篇);

首先是下拉:

<android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swiperefreshlayout"
        android:layout_width="match_parent"
        android:layout_below="@id/title2"
        android:layout_height="wrap_content">
    <android.support.v7.widget.RecyclerView
        android:id="@+id/id_recyclerview"
        android:divider="#ffff0000"
        android:dividerHeight="10dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    </android.support.v4.widget.SwipeRefreshLayout>

这是下拉的样式

然后是下拉的方法

mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                i++;
                String mpath2 = mpath + "&size=30&offset=" + i * 30;
                initData(mpath2);
                mSwipeRefreshLayout.setRefreshing(false);
            }
        });

这里i是要从那条开始儿设置的;自己可以根据自己的数据修改;

上拉这里是到底部自动加载,没有转圈的画面;

mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                int position = manager.findLastVisibleItemPosition();
                Log.d("main",position+"  "+mDatas.size());
                if(position>=mDatas.size()-1){
                    Toast.makeText(MainActivity.this, "到底了", Toast.LENGTH_SHORT).show();
                }
            }
        });
