效果如图,下拉后产生一个水滴的效果

1.在你module的build.gradle中添加依赖

dependencies {    compile 'com.github.recruit-lifestyle:WaveSwipeRefreshLayout:1.6'   }repositories {        maven {            url "https://jitpack.io"        }}

2.在xml中用WaveSwipeRefreshLayout包裹你的控件

          android:id="@+id/wave_swipe"        android:layout_width="match_parent"        android:layout_height="match_parent">                    android:id="@+id/recyclerView"            android:layout_width="match_parent"            android:layout_height="match_parent" />    

3.在Java代码中使用

public class MainActivity extends AppCompatActivity {    @BindView(R.id.wave_swipe)    WaveSwipeRefreshLayout mWaveSwipe;    Handler mHandler = new Handler();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        //设置小圆圈颜色        mWaveSwipe.setColorSchemeColors(Color.WHITE, Color.YELLOW,Color.RED,Color.GREEN);        //设置背景色        mWaveSwipe.setWaveColor(Color.argb(255,63,81,181));        //设置刷新监听        mWaveSwipe.setOnRefreshListener(new WaveSwipeRefreshLayout.OnRefreshListener() {            @Override public void onRefresh() {                new Thread() {                    @Override                    public void run() {                        SystemClock.sleep(3000); //do something in background                        mHandler.post(new Runnable() { //stop refreshing                            @Override                            public void run() {                                //...                                mWaveSwipe.setRefreshing(false);//调用这个方法结束刷新小圆圈的显示                            }                        });                    }                }.start();            }        });    } }
