Use the SmartRefreshLayout control to achieve the most advanced loading and refreshing effects

The most original effect:

                <com.scwang.smartrefresh.layout.SmartRefreshLayout
                    android:id="@+id/mRefreshLayout"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">
                //Adding this is to pull down to refresh the initial head effect
                    <com.scwang.smartrefresh.layout.header.ClassicsHeader
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content" />

                   <RecyclerView   android:id="@+id/mRecyclerView"

                        android:layout_width="match_parent"
                        android:layout_height="match_parent" />

                  //This is the effect of the bottom pull-up loading,
                    <com.scwang.smartrefresh.layout.footer.ClassicsFooter
                        android:id="@+id/mClassicsFooter"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content" />
                </com.scwang.smartrefresh.layout.SmartRefreshLayout>

 

Code:

private RefreshLayout refreshLayout;
refreshLayout=(RefreshLayout)findViewById(R.id.mSwipeRefreshLayout);


        refreshLayout.setOnRefreshListener(new OnRefreshListener() {
            @Override
            public void onRefresh(RefreshLayout refreshlayout) {
                //refresh
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        currpage = 1;
                        // stop refreshing when finished
                        refreshData();
                    }
                }, 100);
                refreshlayout.finishRefresh(1000);
            }
        });
        refreshLayout.setOnLoadmoreListener(new OnLoadmoreListener() {
            @Override
            public void onLoadmore(final RefreshLayout refreshlayout) {
                refreshlayout.finishLoadmore(1000);
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        switch (status) {
                            case 0:
                                currpage++;
                                new StartAsyncTask().execute("initPostInfo");
                               
                                    mAdapter.setNewData(mDetailList);
                                    mAdapter.loadMoreComplete();
                                
                                break;
                            case 1:
                                currpage++;
                                new StartAsyncTask().execute("initPostInfo");
                               
                                    mAdapter.setNewData(mDetailList);
                                    mAdapter.loadMoreEnd();
                               
                                break;
                            case 2:
                              
                                    mAdapter.loadMoreFail();
                              
                                break;
                        }

                    }
                }, 100);
            }
        });

 

If the head and bottom do not need such effects, you can remove them, and then set the desired effects by yourself. If the project does not require special requirements, such effects have already met most of the functional requirements.

 

You can also set global effects

In this way, the drop-down effect of the entire project can be achieved

public class MyApp extends Application{

    static {//static code segment can prevent memory leaks
        //Set the global Header builder
        SmartRefreshLayout.setDefaultRefreshHeaderCreater(new DefaultRefreshHeaderCreater() {
            @Override
            public RefreshHeader createRefreshHeader(Context context, RefreshLayout layout) {
                layout.setPrimaryColorsId(R.color.colorPrimary, android.R.color.white);//Set theme color globally
// return new ClassicsHeader(context).setSpinnerStyle(SpinnerStyle.Translate);//Parallel movement characteristics: the most common, the height of HeaderView will not change,
// return new ClassicsHeader(context).setSpinnerStyle(SpinnerStyle.FixedBehind);//Fixed at the back Features: will not move up and down, HeaderView height will not change (similar to WeChat browser effect)
// return new ClassicsHeader(context).setSpinnerStyle(SpinnerStyle.FixedFront);//Fixed in front features: will not move up and down, HeaderView height will not change
                return new ClassicsHeader(context).setSpinnerStyle(SpinnerStyle.Scale);//Stretching deformation characteristics: When pulling down and up (HeaderView height changes), the OnDraw event will be triggered automatically
            }
        });
        //Set the global Footer builder
        SmartRefreshLayout.setDefaultRefreshFooterCreater(new DefaultRefreshFooterCreater() {
            @Override
            public RefreshFooter createRefreshFooter(Context context, RefreshLayout layout) {
                //Specify as classic Footer, default is BallPulseFooter
//                return new ClassicsFooter(context).setSpinnerStyle(SpinnerStyle.Translate);
//                return new ClassicsFooter(context).setSpinnerStyle(SpinnerStyle.FixedBehind);
//                return new ClassicsFooter(context).setSpinnerStyle(SpinnerStyle.FixedFront);
                return new ClassicsFooter(context).setSpinnerStyle(SpinnerStyle.Scale);
            }
        });
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
}

 

 The following layout can add a header ad slot to the list,

<com.scwang.smartrefresh.layout.SmartRefreshLayout
        android:id="@+id/mRefreshLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        >
        <pl.droidsonroids.gif.GifImageView
            android:layout_width="match_parent"
            android:layout_height="150dp"
            android:scaleType="centerCrop"
            android:src="@mipmap/gif_header_repast"/>
        <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"
            android:orientation="vertical">
            <TextView
                android:layout_width="match_parent"
                android:layout_height="100dp"
                android:gravity="center"
                android:text="I am the banner that boos asked to add"/>


        <android.support.v7.widget.RecyclerView
            android:id="@+id/mRecyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
        </LinearLayout>
    </com.scwang.smartrefresh.layout.SmartRefreshLayout>
