这是一个墙纸应用程序，它通过从Firebase检索图像URL在Picasso的帮助下以网格视图显示图像。如果单击图像，它将在Picasso和firebase的帮助下在新活动中打开。但是，当我运行我的应用程序时，它占用了太多内存，并且使用几分钟后，应用程序崩溃了。我已经使用了android：hardwareAccelerated =“ false”和android：largeHeap =“ true”，但它们无法正常工作。

代码：

Viewholder.java

import ...

public class ViewHolder extends RecyclerView.ViewHolder {

    View mView;

    public ViewHolder(final View itemView) {
        super(itemView);

        mView = itemView;

        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mClickListener.onItemClick(v, getAdapterPosition());
            }
        });

        itemView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {

                mClickListener.onItemLongClick(v, getAdapterPosition());
                return true;
            }
        });

    }


    public void setDetails(Context ctx, String image){


        ImageView mImageTv = mView.findViewById(R.id.rImageView);

        Picasso.get().load(image).into(mImageTv);

    }


    private ViewHolder.ClickListener mClickListener;

    public interface ClickListener{

        void onItemClick(View view, int position);
        void onItemLongClick(View view, int position);

    }

    public void setOnclickListener(ViewHolder.ClickListener clickListener){

        mClickListener = clickListener;

    }


}

在网格视图中显示墙纸的片段

public class HDFragment extends Fragment {

    RecyclerView mRecyclerView;
    FirebaseDatabase mFirebaseDatabase;
    DatabaseReference mRef;


    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_hd, container, false);


        mRecyclerView = view.findViewById(R.id.recyclerView_hd);
        mRecyclerView.setHasFixedSize(true);


        mRecyclerView.setLayoutManager(new GridLayoutManager(getActivity(), 3));


        mFirebaseDatabase = FirebaseDatabase.getInstance();
        mRef = mFirebaseDatabase.getReference("New");

        FirebaseRecyclerAdapter<Model, ViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Model, ViewHolder>(Model.class, R.layout.row, ViewHolder.class, mRef) {
            @Override
            protected void populateViewHolder(ViewHolder viewHolder, Model model, int position) {

                viewHolder.setDetails(getActivity().getApplicationContext(), model.getImage());

            }

            @Override
            public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {


                ViewHolder viewHolder = super.onCreateViewHolder(parent, viewType);
                viewHolder.setOnclickListener(new ViewHolder.ClickListener() {
                    @Override
                    public void onItemClick(View view, int position) {

                        String mImage = getItem(position).getImage();


                        Intent intent = new Intent(view.getContext(), PostDetailsActivity2.class);

                        intent.putExtra("image", mImage);
                        startActivity(intent);


                    }

                    @Override
                    public void onItemLongClick(View view, int position) {


                    }
                });


                return viewHolder;
            }
        };


        mRecyclerView.setAdapter(firebaseRecyclerAdapter);


        return view;
    }
}

FullImage活动在单击时会全屏显示图像

mImageTv = findViewById(R.id.full_imageView1);

        String image = getIntent().getStringExtra("image");


        Picasso.get().load(image).fit().centerCrop().memoryPolicy(MemoryPolicy.NO_CACHE).into(mImageTv);

请帮助。。谢谢

Answer 1

如果您确实需要更多内存，可以在“清单”中为Application设置此属性，以解决问题（也许）：

android:largeHeap="true"

尽管它不是免费提供的，您可以在这篇文章中阅读： What are advantages of setting largeHeap to true?

Answer 2

您正在尝试加载大图像，降低图像分辨率或使用可处理大图像的视图，例如this。

抛出OutOfMemoryError“未能分配28个字节的分配，其中包含4000个可用字节和3KB，直到OOM”
