Android刷新 EasyRefreshLayout 控件

一:导入gradle

	implementation 'com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.24'
    implementation 'com.android.support:recyclerview-v7:28.0.0'
    implementation 'com.github.anzaizai:EasyRefreshLayout:1.3.1'

项目gradle

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

二使用

  <com.ajguan.library.EasyRefreshLayout
        android:id="@+id/easylayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerview"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </com.ajguan.library.EasyRefreshLayout>

MainActivity

public class MainActivity extends AppCompatActivity {

    private EasyRefreshLayout easyRefreshLayout;
    private RecyclerView recyclerView;
    private RecyclerView.LayoutManager layoutManager;
    private SimpleAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
        initListener();
        initData();
    }

    private void initData() {
        List<String> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            list.add("EasyRefreshLayout index :" + i);
        }
        adapter.getData().addAll(list);
        adapter.notifyDataSetChanged();
        adapter.addHeaderView(View.inflate(MainActivity.this, R.layout.headview, null));
    }

    private void initListener() {
        //预加载模式
//        easyRefreshLayout.setLoadMoreModel(LoadModel.ADVANCE_MODEL, 5);
//        easyRefreshLayout.setRefreshHeadView(View.inflate(MainActivity.this, R.layout.refresh_headview, null));
        easyRefreshLayout.addEasyEvent(new EasyRefreshLayout.EasyEvent() {
            @Override
            public void onLoadMore() {

                final List<String> list = new ArrayList<>();
                for (int i = 0; i < 5; i++) {
                    list.add("this is  new load data >>>>" + new Date().toLocaleString());
                }
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        easyRefreshLayout.loadMoreComplete();
                        int postion = adapter.getData().size();
                        adapter.getData().addAll(list);
                        adapter.notifyDataSetChanged();
                    }
                }, 500);

            }

            @Override
            public void onRefreshing() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        List<String> list = new ArrayList<>();
                        for (int i = 0; i < 20; i++) {
                            list.add("this is refresh data >>>" + new Date().toLocaleString());
                        }
                        adapter.setNewData(list);
                        easyRefreshLayout.refreshComplete();
                        Toast.makeText(getApplicationContext(), "refresh success", Toast.LENGTH_SHORT).show();
                    }
                }, 1000);

            }
        });
    }

    private void initView() {
        easyRefreshLayout = (EasyRefreshLayout) findViewById(R.id.easylayout);
        recyclerView = (RecyclerView) findViewById(R.id.recyclerview);
        layoutManager = new LinearLayoutManager(this);
        recyclerView.setLayoutManager(layoutManager);
        recyclerView.setHasFixedSize(true);
        adapter = new SimpleAdapter();
        recyclerView.setAdapter(adapter);
    }
}

Adapter

public class SimpleAdapter extends BaseQuickAdapter<String,BaseViewHolder> {
    public SimpleAdapter() {
        super(R.layout.items_recyclerview, null);
    }

    @Override
    protected void convert(BaseViewHolder helper, String item) {
        helper.setText(R.id.text,item);

    }
}

item.layout
