Question

目标

传递图像（它占据屏幕的四分之一，因此它非常大）用于活动/片段。

我尝试做什么

我没有绕过BitMaps，而是被研究/建议传递图像Uri。问题是，每当我点击＆＃34;预览按钮＆＃34;，它将启动HomeDescActivity时，就会出现Out of Memory Exception。

GalleryFragment

public class GalleryFragment extends Fragment {
    private static final int SELECT_PICTURE = 1;
    public static final String IMAGE_URI_ARRAY_LIST = "IMAGE_URI_ARRAY_LIST";
    private ArrayList<String> mImageUriArrayList = new ArrayList<>();
    RecyclerView recyclerView;
    GalleryAdapter galleryAdapter;

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

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        //convert string uri to uri object
        Uri imageUri = Uri.parse(getArguments().getString(PhotoFragment.IMAGE_URI));


        recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
        galleryAdapter = new GalleryAdapter();
        galleryAdapter.addImage(imageUri);
        mImageUriArrayList.add(imageUri.toString());


        GridLayoutManager gridLayoutManager = new GridLayoutManager(getActivity(), 2);
        recyclerView.setLayoutManager(gridLayoutManager);

        view.findViewById(R.id.ivAddPhoto).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                //Launch Gallery
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,
                        "Select Picture"), SELECT_PICTURE);
            }
        });

        view.findViewById(R.id.bPreview).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getContext(), HomeDescActivity.class);
                intent.putStringArrayListExtra(IMAGE_URI_ARRAY_LIST, mImageUriArrayList);
                startActivity(intent);
            }
        });
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                //get selected image from gallery
                Uri imageUri = data.getData();
                galleryAdapter.addImage(imageUri);
                mImageUriArrayList.add(imageUri.toString());
                //refresh adapter
                recyclerView.setAdapter(galleryAdapter);

            }
        }
    }
}

HomeDescActivity （启动时会导致Out of Memory异常）

public class HomeDescActivity extends AppCompatActivity {

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

        HomeDescFragment homeDescFragment = new HomeDescFragment();

//        Get images (uri) from GalleryFragment + PhotoFragment
        if(getIntent().getExtras().getStringArrayList(GalleryFragment.IMAGE_URI_ARRAY_LIST) != null){
                Bundle bundle = new Bundle();
            bundle.putStringArrayList(GalleryFragment.IMAGE_URI_ARRAY_LIST,
                    getIntent().getExtras().getStringArrayList(GalleryFragment.IMAGE_URI_ARRAY_LIST));

            homeDescFragment.setArguments(bundle);
            getSupportFragmentManager().beginTransaction().replace(R.id.rootLayout, homeDescFragment).commit();
        }

    }

}

HomeDescFragment

public class HomeDescFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.explore_tab_home_desc_fragment, container, false);

        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        //convert strng uri to uri object
        if(getArguments().getStringArrayList(GalleryFragment.IMAGE_URI_ARRAY_LIST) != null){
            ArrayList<String> uriArrayList = getArguments().getStringArrayList(GalleryFragment.IMAGE_URI_ARRAY_LIST);
            ImageView ivHomePhoto = (ImageView) view.findViewById(R.id.ivHomePhoto);

            for(String uriString : uriArrayList){
               ivHomePhoto.setImageURI(Uri.parse(uriString));
            }
        }

    }
}

Answer 1

向我们展示堆栈跟踪。

向我们提供有关导致异常的图像的详细信息，它的宽度和高度是多少，需要多少内存？

我猜你正在尝试加载一个像6000x6000那样愚蠢的高分辨率图像，导致异常，但没有更多信息，我不能说更多。

您应该使用像“Glide”这样的库来为您加载图像，因为如果图像太大，它会向用户显示缩小图像。使用最少的内存来处理图像也非常有效。

用图像传递图像＆＃39; Uri仍会导致内存不足异常
