Ways to pass data using intent in Android development

Activity passes values between intent, supports basic data types and string objects and their array objects byte, byte[], Char, char[], Boolean, boolean[], short, short[], int, int [], Long, long[], float, float[], double, double[], String, string[], and adopt the implementation of Serializable, The Parcelable interface's class object passes data in two ways: one is bundle.putserializable (Key,object) and the other is Bundle.putparcelable (Key, Object)

For example:

[Java]View Plaincopyprint?

2. Import Android.os.Parcel;
4. Import android.os.Parcelable;
6. Public class book implements Parcelable {
8. private String BookName;
10. private String author;
12. private int publishtime;
16. Public String Getbookname () {
18. return bookname;
20. }
22. public void Setbookname (String bookname) {
24. this.bookname = bookname;
26. }
28. Public String Getauthor () {
30. return author;
32. }
34. public void Setauthor (String author) {
36. This.author = author;
38. }
40. public int Getpublishtime () {
42. return publishtime;
44. }
46. public void setpublishtime (int publishtime) {
48. this.publishtime = publishtime;
50. }
54. public static final parcelable.creator<book> Creator = new creator<book> () {
56. Public book Createfromparcel (Parcel source) {
58. Book Mbook = new book ();
60. Mbook.bookname = Source.readstring ();
62. Mbook.author = Source.readstring ();
64. Mbook.publishtime = Source.readint ();
66. return mbook;
68. }
70. Public book[] NewArray (int size) {
72. return new book[size];
74. }
76. };
80. public int describecontents () {
82. return 0;
84. }
86. public void Writetoparcel (Parcel Parcel, int flags) {
88. Parcel.writestring (BookName);
90. Parcel.writestring (author);
92. Parcel.writeint (Publishtime);
94. }
96. }

Implement the Serializable interface:

[Java]View Plaincopyprint?

2. Import java.io.Serializable;
4. Public class Person implements Serializable {
6. private Static final long serialversionuid = -7060210544600464481l;
8. private String name;
10. private int age;
12. Public String GetName () {
14. return name;
16. }
18. public void SetName (String name) {
20. this.name = name;
22. }
24. public int getage () {
26. return age;
28. }
30. public void Setage (int.) {
32. this.age = age;
34. }
38. }

This allows you to write the pass-through data code in the activity:

[Java]View Plaincopyprint?

1. Intent mintent = new Intent (this, address activity.     Class);
2. Bundle Mbundle = new Bundle ();
3. Transfer data using parcelable
4. Mbundle.putparcelable ("Data", Mbook);
5. Transfer data using Serializable
6. Mbundle.putserializable ("data", items);
7. Mintent.putextras (Mbundle);
9. StartActivity (mintent);

Accepted data can be used:

[Java]View Plaincopyprint?

1. Intent Intent = Getintent ();
2. arraylist<map<string, string>> items = (arraylist<map<string, string>>) Intent.getExtras ().  Get ("data");
