Question

我正在处理this项目，但我遇到了问题。如果我选择高分辨率（例如：2 MB）图像应用程序崩溃。我怎样才能解决这个问题？

我的sqlite表：

Id INTEGER PRIMARY KEY AUTOINCREMENT，名称VARCHAR，价格VARCHAR，图片BLOB

图片插入代码：

  public static byte[] imageViewToByte(ImageView image) {
    Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] byteArray = stream.toByteArray();
    return byteArray;
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    if(requestCode == REQUEST_CODE_GALLERY){
        if(grantResults.length >0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setType("image/*");
            startActivityForResult(intent, REQUEST_CODE_GALLERY);
        }
        else {
            Toast.makeText(getApplicationContext(), "Bu dosyaya erişiminiz yok !", Toast.LENGTH_SHORT).show();
        }
        return;
    }

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if(requestCode == REQUEST_CODE_GALLERY && resultCode == RESULT_OK && data != null){
        Uri uri = data.getData();

        try {
            InputStream inputStream = getContentResolver().openInputStream(uri);

            Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
            imageView.setImageBitmap(bitmap);

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }

    super.onActivityResult(requestCode, resultCode, data);
}

FoodList.java获取数据代码：

protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.food_list_activity);

    gridView = (GridView) findViewById(R.id.gridView);
    list = new ArrayList<>();
    adapter = new FoodListAdapter(this, R.layout.food_items, list);
    gridView.setAdapter(adapter);

    // get all data from sqlite
    Cursor cursor = MainActivity.sqLiteHelper.getData("SELECT * FROM FOOD");
    list.clear();
    while (cursor.moveToNext()) {
        int id = cursor.getInt(0);
        String name = cursor.getString(1);
        String price = cursor.getString(2);
        byte[] image = cursor.getBlob(3);

        list.add(new Food(name, price, image, id));
    }
    adapter.notifyDataSetChanged();
