Android进程间(AIDL)高效传输数据--Parcelab

由于Serializable效率过慢，为了在程序内不同组件及进程间(AIDL)高效的传输数据，Android推出了Parceable的设计，这些数据仅在内存中存在。

通Serial过Intent传递Parcelable对象

Intent.putExtra(key,Parcelable);

创建序列化类：

public class CityVPN implements P arcelable {

public String vpn_type_brand="";

public int vpn_type_status= -1;

public boolean selected;

public static final Parcelable.Creator<CityVPN> CREATOR = new Parcelable.Creator<CityVPN>() {

public CityVPN createFromParcel(Parcelin) {

return new CityVPN(in);

}

public CityVPN[] newArray(intsize) {

return new CityVPN[size];

}

};

public CityVPN(Parcel in) {

vpn_type_brand = in.readString();

vpn_type_status = in.readString();

selected= in.readByte() != 0;

}

@Override

publicintdescribeContents() {

return0;

}

@Override

public void writeToParcel(Parcel arg0,int arg1) {

arg0.writeString(privonce);

arg0.writeInt(vpn_type_status);

arg0.writeByte((byte)(selected? 1 : 0));

}

}
