在使用的过程中会报错：An instance of OnFlingListener already set“”

[WUSIR-ShiYan]

loadService = LoadSir.getDefault().register(this, new Callback.OnReloadListener() {
@OverRide
public void onReload(View v) {
// Your can change the status out of Main thread.
new Thread(new Runnable() {
@OverRide

                    //增加这一段即可

@WUSIR-ShiYan 你好，我的实例代码中没有使用到RecyclerView，你在使用SnapHelper吗，能否给出完整的代码，我好判断是LoadSir的原因还是其它原因。

我在一个demo中用在了recyclerview的item点击事件中，第一次点击，正常显示no data的页面，当再次点击该页面就会报这个错误，错误信息如下： FATAL EXCEPTION: main Process: com.whp.whp_proj, PID: 8396 java.lang.IllegalStateException: An instance of OnFlingListener already set. at android.support.v7.widget.SnapHelper.setupCallbacks(SnapHelper.java:114) at android.support.v7.widget.SnapHelper.attachToRecyclerView(SnapHelper.java:102) at com.stone.vega.library.VegaLayoutManager.onAttachedToWindow(VegaLayoutManager.java:223) at android.support.v7.widget.RecyclerView$LayoutManager.dispatchAttachedToWindow(RecyclerView.java:7394) at android.support.v7.widget.RecyclerView.onAttachedToWindow(RecyclerView.java:2490) at android.view.View.dispatchAttachedToWindow(View.java:15810) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3137) at android.view.ViewGroup.dispatchAttachedToWindow(ViewGroup.java:3145) at android.view.ViewGroup.addViewInner(ViewGroup.java:4693) at android.view.ViewGroup.addView(ViewGroup.java:4490) at android.view.ViewGroup.addView(ViewGroup.java:4431) at android.view.ViewGroup.addView(ViewGroup.java:4404) at com.kingja.loadsir.core.LoadLayout.showCallbackView(LoadLayout.java:74) at com.kingja.loadsir.core.LoadLayout.access$000(LoadLayout.java:20) at com.kingja.loadsir.core.LoadLayout$1.run(LoadLayout.java:63) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:158) at android.app.ActivityThread.main(ActivityThread.java:7225) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1230) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1120) 其中，错误定位到了com.kingja.loadsir.core.LoadLayout.showCallbackView(LoadLayout.java:74)，这个是你loadsir那个库里的代码，如下是你的示例程序里的用法，我在回调里面做的处理的该异常： loadService = LoadSir.getDefault().register(this, new Callback.OnReloadListener() { @OverRide public void onReload(View v) { // Your can change the status out of Main thread. new Thread(new Runnable() { @OverRide public void run() { loadService.showCallback(LoadingCallback.class); //do retry logic... SystemClock.sleep(500); //我的demo中做的如下处理 if(recyclerView.getOnFlingListener() != null){ recyclerView.setOnFlingListener(null); } //callback loadService.showSuccess(); } }).start(); } }); 在 2017-09-26 13:11:05，"KingJA" <notifications@github.com> 写道： @WUSIR-ShiYan 你好，我的实例代码中没有使用到RecyclerView，你在使用SnapHelper吗，能否给出完整的代码，我好判断是LoadSir的原因还是其它原因。 — You are receiving this because you were mentioned.

@WUSIR-ShiYan 可以直接把Demo压缩包发我邮箱吗

[WUSIR-ShiYan]

好的，其实就是RecyclerView最基本的使用，报的这个错误很奇怪，我的demo里也没有使用onFlingListener，在demo里处理一下就可以了 在 2017-09-26 13:49:36，"KingJA" <notifications@github.com> 写道： @WUSIR-ShiYan 可以直接把Demo压缩包发我邮箱吗 — You are receiving this because you were mentioned.
