Question

每次关闭应用或更改标签时，我都会崩溃：

我在该片段中使用Horizontal RecyclerView：

RecyclerView mRecyclerView = (RecyclerView) rootView.findViewById(R.id.itv_submenu_recycler_view);
// use a linear layout manager
mLayoutManager = new LinearLayoutManager(getActivity());
mLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
mRecyclerView.setLayoutManager(mLayoutManager);
mAdapter = new SubMenuItemsAdapter(subMenuTabChangeListener);
mRecyclerView.setAdapter(mAdapter);

和回收者视图是

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
    android:id="@+id/itv_submenu_recycler_view"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" />

我正在使用以下库来进行recyclerView：

compile 'com.android.support:support-v13:25.0.0'
compile 'com.android.support:appcompat-v7:25.3.0'
compile 'com.android.support:recyclerview-v7:25.3.+'

此问题仅出现在一部手机（Kitkat设备）上。请帮我解决这个崩溃。感谢

您使用支持库25.3.0，可能是发生崩溃的手机没有在手机上更新最新的Google Play服务。

检查

private void checkGooglePlayServices(){
    GoogleApiAvailability api = GoogleApiAvailability.getInstance();
    int code = api.isGooglePlayServicesAvailable(this);
    if (code == ConnectionResult.SUCCESS) {
        onActivityResult(REQUEST_GOOGLE_PLAY_SERVICES, Activity.RESULT_OK, null);
    } else if (api.isUserResolvableError(code) &&
            api.showErrorDialogFragment(this, code, REQUEST_GOOGLE_PLAY_SERVICES)) {
        // wait for onActivityResult call (see below)
    } else {

        Toast.makeText(this, api.getErrorString(code), Toast.LENGTH_LONG).show();
    }
}

和

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch(requestCode) {
        case REQUEST_GOOGLE_PLAY_SERVICES:
            if (resultCode == Activity.RESULT_OK) {
                loadData();
            }
            break;

        default:
            super.onActivityResult(requestCode, resultCode, data);
    }
}

@wrkwrk伤心可能是一种可能性，但通常更多的手机会出现问题，而不仅仅是一个。

在另一个节点上尝试不使用Gradle中的+指示器，每次尝试构建应用程序时，Gradle都必须检查最新版本是什么，并且只花费构建时间。

片段破坏时，Recycler View崩溃
