Java语言带有ArrayList和RecyclerView的lang.OutOfMemoryError

Question

并提前感谢您的帮助。我试图将ArrayList放入RecyclerView，但我得到了这个错误：

Clog_eOutOfMemoryError：未能分配7224906字节分配4194304可用字节和4MB直到OOM在riter.java:625AbstractStringBcom.android.internal.util.缓冲区（AbstractStringBriter.append）riter.java:658AbstractStringBjava.io.0（AbstractStringBriter.append）在riter.java:691StringBjava.io.（StringBriter.append）在riter.java:31StringWjava.lang.（StringWhrowable.print）在com.android.internal.util.FastPrintWriter.flush锁定（FastPrintWriter.java:358）在com.android.internal.util.FastPrintWriter.append锁定（FastPrintWriter.java:303）在com.android.internal.util.FastPrintWjava.lang.（FastPrintWjava.lang.）uilder.enlargeFastPrintWuilder.java:95（FastPrintWjava.lang.）在uilder.appendPrintWuilder.java:125（PrintWjava.lang.）在uffer.appendPrintWuffer.java:278（PrintWjava.io.）在riter.writeTriter.java:123StackTrace（Throwable. java： 324）在android. util.

我的代码（有问题的部分）是这样的：

public class TabFragment5 extends Fragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    RecyclerView rv = (RecyclerView) inflater.inflate(
            R.layout.fragment_pat_list, container, false);
    setupRecyclerView(rv);
    return rv;
}

private void setupRecyclerView(RecyclerView recyclerView) {
    recyclerView.setLayoutManager(new LinearLayoutManager(recyclerView.getContext()));
    recyclerView.setAdapter(new SimpleStringRecyclerViewAdapter(getActivity(),
            getList(Infos.sPatGrandi)));
}


private ArrayList<String> getList(String[] array) {
    ArrayList<String>list = new ArrayList<String>getList(Infos.sPatGrandi));
    while (list.size()<40){
        list.addAll(getList(Infos.sPatGrandi));
    }
    return list;
}

我只有在这部分代码中才会出现这个错误，有人能解释原因吗？非常感谢，祝你玩得愉快！

Answer 1

在方法getList中有一个递归调用，由于这个递归调用，分配了很多对象。这将生成您的OutOfMemoryException。

编辑示例：

List<String> listOfData = new ArrayList<>();
SimpleStringRecyclerViewAdapter adapter = new SimpleStringRecyclerView(context, listOfData);
recyclerView.setAdapter(adapter);
//Now add more content to the list
listOfData.add("new item");
listOfData.add("another item");
//This notifies the adapter and the list that the content has changed
adapter.notifyDataSetChanged();
