Applications in the android parcelable Project

Data may be transferred between activities. If it is a basic type and a string type, it is easy to do. Android already provides related APIs.

However, if you want to pass an object class, such as a friend class: buddyinfo, there is no relevant API for calling. You can use parcebale at this time.

ViewCode:

Entity class:

Import android. OS. parcel; import android. OS. parcelable; public class buddyinfo implements parcelable {private string nickname; private string SIG; private int image; Public buddyinfo (string nickname, string Sig, int image) {setnickname (nickname ); setsig (SIG); setimage (image);} public buddyinfo (parcel source) {nickname = source. readstring (); Sig = source. readstring (); image = source. readint () ;}@ overridepublic int describecontents () {return 0;} public static final parcelable. creator <buddyinfo> creator = new creator <buddyinfo> () {@ overridepublic buddyinfo [] newarray (INT size) {return New buddyinfo [size];} @ overridepublic buddyinfo createfromparcel (parcel source) {return New buddyinfo (source) ;};@ overridepublic void writetoparcel (parcel DEST, int flags) {DeST. writestring (nickname); DeST. writestring (SIG); DeST. writeint (image);} Public String getnickname () {return nickname;} public void setnickname (string nickname) {This. nickname = nickname;} Public String getsig () {return SIG;} public void setsig (string sig) {This. sig = SIG;} public int getimage () {return image;} public void setimage (INT image) {This. image = image ;}}

Encapsulate in intent:

 
Mbuddyinfo = newbuddyinfo (*******************); intent = new intent (this, chatactivity. class); intent. putextra (Buddy, mbuddyinfo); startactivity (intent );
 

Get data:

 
Mintent = This. getintent (); parcelable = mintent. getparcelableextra (Buddy); mbuddyinfo = (buddyinfo) parcelable; mbuddyname = mbuddyinfo. getnickname ();
 

Is it easy?
