Question

请给我帮助。在这部分中我仍然是错误，并且我尝试运行，但是仍然有错误。当我从URL加载图像时，会出现以下问题：

我需要帮助。这是我的Java类。我不知道错误在哪里。我还添加了它：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

公共类But1_room扩展了AppCompatActivity {

private static final String TAG = "But1_room";

//Vars
private ArrayList<String> mNames = new ArrayList<>();
private ArrayList<String> mImageUrls = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_but1_room);

    Log.d(TAG, "onCreate: started.");

    initImageBitmaps();

}

private void initImageBitmaps()
{

    initRecyclerView();
}

    Log.d(TAG, "initRecyclerView: init recyclerview.");
    RecyclerView recyclerView = findViewById(R.id.recycler_view);
    RecyclerViewAdapter adapter = new RecyclerViewAdapter(this, mNames, mImageUrls);
    recyclerView.setAdapter(adapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
}
}

在这一部分，你能帮我吗？？

java.io.FileNotFoundException：打开失败：ENOENT（没有这样的文件或目录），而从URL读取图像
