I want to create and write data to a parcel. The reason i want to do the following is debugging. I want to write some concise code in one location which enable a certain flow in the application.
I want to modify this method to return an object which I create:
public MyMessage getMyMessage() {
return myMessage;
}
MyMessage is a bean defined as:
@Bean
public class MyMessage implements Parcelable {
@Optional
private String message;
public MyMessage() {
}
public MyMessage(Parcel in) {
message = in.readString();
}
public String getMessage() {
return message;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(message);
}
public static final Creator<MyMessage> CREATOR = new Creator<MyMessage>() {
@Override
public MyMessage createFromParcel(Parcel in) {
return new MyMessage(in);
}
@Override
public MyMessage[] newArray(int size) {
return new MyMessage[size];
}
};
}
I do not want to edit the MyMessage class and add a constructor or setter methods. MyMessage should stay exactly the same and I want to fill its messagefield by constructing a MyMessage object with a parcel.
I have tried this:
public MyMessage getMyMessage() {
android.os.Parcel parcel = android.os.Parcel.obtain(); // TODO
parcel.writeString("message is this");
return MyMessage.CREATOR.createFromParcel(parcel);
//return new MyMessage(parcel);
}
But the .writeString()does not seem to modify the parcel, the debugger detaches and i cannot step through it. The end result then is that the MyMessage bean has a null message. Where am I going wrong?
