Question

并提前感谢您的帮助。我试图将ArrayList放入RecyclerView，但我收回了这个错误：

java.lang.OutOfMemoryError：无法分配7224906字节分配4194304空闲字节和4MB直到OOM at java.lang.AbstractStringBuilder.enlargeBuffer（AbstractStringBuilder.java:95） at java.lang.AbstractStringBuilder.append0（AbstractStringBuilder.java:125）在java.lang.StringBuffer.append（StringBuffer.java:278） at java.io.StringWriter.write（StringWriter.java:123）在com.android.internal.util.FastPrintWriter.flushLocked（FastPrintWriter.java:358）在com.android.internal.util.FastPrintWriter.appendLocked（FastPrintWriter.java:303）在com.android.internal.util.FastPrintWriter.write（FastPrintWriter.java:625）在com.android.internal.util.FastPrintWriter.append（FastPrintWriter.java:658）在java.io.PrintWriter.append（PrintWriter.java:691）在java.io.PrintWriter.append（PrintWriter.java:31）在java.lang.Throwable.printStackTrace（Throwable.java:324）在java.lang.Throwable.printStackTrace（Throwable.java:300）在android.util.Log.getStackTraceString（Log.java:335）在com.android.internal.os.RuntimeInit.Clog_e（RuntimeInit.java:59）在com.android.internal.os.RuntimeInit.access $ 200（RuntimeInit.java:43） at com.android.internal.os.RuntimeInit $ UncaughtHandler.uncaughtException（RuntimeInit.java:85） at java.lang.ThreadGroup.uncaughtException（ThreadGroup.java:693）在java.lang.ThreadGroup.uncaughtException（ThreadGroup.java:690）

我的代码（有问题的部分）是：

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;
}

我只用这部分代码得到这个错误，有人可以解释一下原因吗？非常感谢，祝你玩得愉快！

您在方法getList中进行了递归调用，由于此递归调用而分配了很多对象。这产生了OutOfMemoryException。

修改示例：

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();

带有ArrayList和RecyclerView的java.lang.OutOfMemoryError
