如何使用ArrayList正确实现Mailable<Parcelable>?
2022-08-31 13:07:55
我在上课时遇到了麻烦。麻烦的是,我试图将类中的成员写入包裹,这是一个对象。列表中的 is 和对象 () 是 。Parcelable
ArrayList<Parcelable>
ArrayList
Serializable
ZigBeeDev
Parcelable
以下是相关代码:
package com.gnychis.coexisyst;
import java.util.ArrayList;
import java.util.Iterator;
import android.os.Parcel;
import android.os.Parcelable;
public class ZigBeeNetwork implements Parcelable {
public String _mac; // the source address (of the coordinator?)
public String _pan; // the network address
public int _band; // the channel
ArrayList<Integer> _lqis; // link quality indicators (to all devices?)
ArrayList<ZigBeeDev> _devices; // the devices in the network
public void writeToParcel(Parcel out, int flags) {
out.writeString(_mac);
out.writeString(_pan);
out.writeInt(_band);
out.writeSerializable(_lqis);
out.writeParcelable(_devices, 0); // help here
}
private ZigBeeNetwork(Parcel in) {
_mac = in.readString();
_pan = in.readString();
_band = in.readInt();
_lqis = (ArrayList<Integer>) in.readSerializable();
_devices = in.readParcelable(ZigBeeDev.class.getClassLoader()); // help here
}
public int describeContents() {
return this.hashCode();
}
public static final Parcelable.Creator<ZigBeeNetwork> CREATOR =
new Parcelable.Creator<ZigBeeNetwork>() {
public ZigBeeNetwork createFromParcel(Parcel in) {
return new ZigBeeNetwork(in);
}
public ZigBeeNetwork[] newArray(int size) {
return new ZigBeeNetwork[size];
}
};
//...
}
我已经标记了两个点“//帮助这里”,以了解如何正确写入包裹以及如何重建它。如果 是(经过适当测试),我该如何正确执行此操作?ZigBeeDev
Parcelable
