Android Bundle Transfer Data

1. Passing Normal data

                Intent intent=New Intent (mainactivity.  this, twoactivity. class );                Bundle Bundle=new  bundle ();                Bundle.putstring ("name", "Zhang San");                Bundle.putint ("age",);                Bundle.putstring ("gender", "male");                Intent.putextras (bundle);                StartActivity (intent);

Get the data passed

        Bundle bundle=getintent (). Getextras ();        String name=bundle.getstring ("name");        String gender=bundle.getstring ("Gender");         int Age =bundle.getint ("age");    

2. Passing serializable data

1. Create a class implementation serializable

2. Passing Data

                Intent intent=New Intent (mainactivity.  this, twoactivity. class );                Bundle Bundle=new  bundle ();                Person1 P1=new Person1 ("Zhang San", "male",);                Bundle.putserializable ("person", p1);                Intent.putextras (bundle);                StartActivity (intent);

3. Acceptance of data

        Bundle bundle=getintent (). Getextras ();        Person1 P1= (Person1) bundle.getserializable ("person");        String name=p1.getname ();        String Gender=p1.getgender ();         int Age =p1.getage ();

3. Passing parcelable Data

1. Create a class implementation Parcelabel

 Public classPerson3Implementsparcelable {PrivateString name; PrivateString Gender; Private intAge ;  PublicPerson3 (string name, String gender,intAge ) {         This. Name =name;  This. Gender =gender;  This. Age =Age ; }     PublicString GetName () {returnname; }     PublicString Getgender () {returngender; }     Public intGetage () {returnAge ; } @Override PublicString toString () {return"person3{" + "name=" + name + "\" + ", gender=" + gender + "\" + ", age=" + Age + '} '; }     Public Static FinalParcelable.creator<person3> creator=NewParcelable.creator<person3>(){        /*** For external class inverse sequence of the colloquial class array using *@paramSource *@return         */@Override PublicPerson3 Createfromparcel (Parcel source) {return NewPerson3 (source); }        /*** Read data from Parcel *@paramSize *@return         */@Override PublicPerson3[] NewArray (intsize) {            return NewPerson3[size];    }    }; /*** 0 is returned by default *@return     */@Override Public intdescribecontents () {return0; }    /*** Write the values into the parcel *@paramdest *@paramFlags*/@Override Public voidWritetoparcel (Parcel dest,intflags)        {dest.writestring (name);        Dest.writestring (gender);    Dest.writeint (age); }    /*** The read data must be consistent with Writetoparacel (Parcel dest,int flags), otherwise it will be an error *@paramSource*/     PublicPerson3 (Parcel source) {Name=source.readstring (); Gender=source.readstring (); Age=Source.readint (); }}

2. Passing Data

                Intent intent=New Intent (mainactivity.  this, twoactivity. class );                Bundle Bundle=new  bundle ();                Person3 P3=new Person3 ("Zhang San", "male",);                Bundle.putparcelable ("person", p3);                Intent.putextras (bundle);                StartActivity (intent);

3. Acceptance of data

Bundle bundle=getintent (). Getextras ();        Person3 P3= bundle.getparcelable ("person");        String name=p3.getname ();        String Gender=p3.getgender ();         int Age =p3.getage ();
