从 Fragment 移动到 Activity 会导致 android.os.TransactionTooLargeException

问题描述 投票:0回答:2

我正在尝试使用意图从片段移动到活动,并且在我运行代码的地方,它会导致

android.os.TransactionTooLargeException

我的片段代码(CardFragment.java):

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

    txtName = view.findViewById(R.id.txt_name);
    btnFood = view.findViewById(R.id.btn_food);

    txtName.setText(mName);

    Bitmap bm = StringToBitMap(mImage);
    btnFood.setImageBitmap(bm);

    btnFood.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), Recipes.class);
            intent.putExtra("Name", mName);
            intent.putExtra("Recipe", mRecipe);
            intent.putExtra("Image", mImage);
            startActivity(intent);
        }
    });
}

mName
mRecipe
mImage
是字符串变量。

我的活动代码(Recipes.java):

public class Recipes extends AppCompatActivity {

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

        TextView txtName = findViewById(R.id.txt_name);
        TextView txtRecipe = findViewById(R.id.txt_recipe);
        ImageView imgView = findViewById(R.id.img_view);

        txtName.setText(getIntent().getStringExtra("Name"));
        txtRecipe.setText(getIntent().getStringExtra("Recipe"));

        Bitmap bm = CardFragment.StringToBitMap(getIntent().getStringExtra("Image"));
        imgView.setImageBitmap(bm);
    }
}

每次运行此代码时,我都会收到此错误消息:

这个错误是什么?我该如何解决它?也许是因为我之前的视图中有多个

CardFragment
?感谢您的帮助。

此错误意味着您通过 Intent 发送了超过 1 MB 的数据,在这种情况下,您的位图对于 Intent 来说太大了。

解决方案是减小位图大小或使用不同的方式传递位图之类的服务等

解决方案是本地缓存,github上有一个库可以做到这一点https://github.com/kernel0x/bundlesaver
