Android: How to put an Enum in a Bundle?

Question

How do you add an Enum object to an Android Bundle?

Answer 1

Enums are Serializable so there is no issue.

Given the following enum:

enum YourEnum {
  TYPE1,
  TYPE2
}

Bundle:

// put
bundle.putSerializable("key", YourEnum.TYPE1);

// get 
YourEnum yourenum = (YourEnum) bundle.get("key");

Intent:

// put
intent.putExtra("key", yourEnum);

// get
yourEnum = (YourEnum) intent.getSerializableExtra("key");

Answer 2

I know this is an old question, but I came with the same problem and I would like to share how I solved it. The key is what Miguel said: Enums are Serializable.

Given the following enum:

enum YourEnumType {
    ENUM_KEY_1, 
    ENUM_KEY_2
}

Put:

Bundle args = new Bundle();
args.putSerializable("arg", YourEnumType.ENUM_KEY_1);

Answer 3

For completeness sake, this is a full example of how to put in and get back an enum from a bundle.

Given the following enum:

enum EnumType{
    ENUM_VALUE_1,
    ENUM_VALUE_2
}

You can put the enum into a bundle:

bundle.putSerializable("enum_key", EnumType.ENUM_VALUE_1);

And get the enum back:

EnumType enumType = (EnumType)bundle.getSerializable("enum_key");

Answer 4

I use kotlin.

companion object {

        enum class Mode {
            MODE_REFERENCE,
            MODE_DOWNLOAD
        }
}

then put into Intent:

intent.putExtra(KEY_MODE, Mode.MODE_DOWNLOAD.name)

when you net to get value:

mode = Mode.valueOf(intent.getStringExtra(KEY_MODE))
