我使用 ImageView 并从服务器设置图片，我使用Volley库连接服务器并获取数据。
但启动应用程序和滚动项目时，显示FC错误。我的商品有RecyclerView，CardView和自定义ImageView。
我的适配器代码：
public class DataAdapter extends RecyclerView.Adapter {
private final int VIEW_ITEM = 1;
private final int VIEW_PROG = 0;
private List<newSMS_class> sms_list;
private int visibleThreshold = 5;
private int lastVisibleItem, totalItemCount;
private boolean loading;
private OnLoadMoreListener onLoadMoreListener;
private Bitmap bm;
private Context context;
public DataAdapter(List<newSMS_class> sms_list_use, RecyclerView recyclerView) {
sms_list = sms_list_use;
context = recyclerView.getContext();
if (recyclerView.getLayoutManager() instanceof LinearLayoutManager) {
final LinearLayoutManager linearLayoutManager = (LinearLayoutManager) recyclerView
.getLayoutManager();
recyclerView
.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView,
int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
totalItemCount = linearLayoutManager.getItemCount();
lastVisibleItem = linearLayoutManager
.findLastVisibleItemPosition();
if (!loading
&& totalItemCount <= (lastVisibleItem + visibleThreshold)) {
if (onLoadMoreListener != null) {
onLoadMoreListener.onLoadMore();
}
loading = true;
}
}
});

请帮我修理一下。大tnx＆lt; 3
答案 0 :(得分：2)
正如@Selvin所说，你不应该为每个图像创建新的请求。
为此，您需要从“Bitmap getImg(String url)”方法中删除以下行。
"RequestQueue queue = Volley.newRequestQueue(context);"
例如，将变量声明放在某处，如下面的Context声明之后：
...
private Bitmap bm;
private Context context;
RequestQueue queue = Volley.newRequestQueue(context);
...
答案 1 :(得分：2)
从每个工作活动中发起新的requestQueue实际上并不是一个好主意。
相反，我创建了一个类似于以下的应用程序类 -
public class ApplicationController extends Application{
private static ApplicationController thisInstance ;
private RequestQueue mRequestQueue ;
@Override
public void onCreate() {
super.onCreate();
thisInstance = this ;
}
public static synchronized ApplicationController getInstance(){
return thisInstance ;
}
public RequestQueue getmRequestQueue(){
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(getApplicationContext());
}
return mRequestQueue;
}
无论我在哪里初始化，我都用
requestQueue = ApplicationController.getInstance().getmRequestQueue();
您只需将其添加到您的Manifest应用程序元素的名称属性中，您可以在其中提供您的班级名称。
<application
android:name=".ApplicationController"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:theme="@style/AppTheme">
但我认为您现在只拥有整个应用的一个RequestQueue 实例。如果您认为可能会产生大量的HttpRequests，那么您可以根据需要在某些活动中实例化RequestQueues。这对我帮助很大。我希望它也可以帮到你。
