我有一个名为AdViewed的类，它实现了Parcelable。
以下是代码：
public class AdViewed implements Parcelable {
protected long timeStamp;
protected String country, city, lat, lng, ad_id, poster_id, user_id, latLng;
public void hydrate(HashMap<String, ?> map){
Method[] methodes = this.getClass().getMethods();
Iterator it = map.keySet().iterator();
while(it.hasNext()){
Object key = it.next();
Object value = map.get(key);
String valueS = value.toString();
String method = "set" + key.toString();
for(Method methode : methodes){
if(methode.getName().equals(method)){
try{
methode.invoke(AdViewed.this, valueS);
}
catch(InvocationTargetException e){
e.printStackTrace();
}
catch(IllegalAccessException e){
e.printStackTrace();
}
}
}
}
}
public AdViewed(long timeStamp1, String country1, String city1, String lat1, String lng1, String ad_id1, String poster_id1,
String user_id1, String latLng1){
this.timeStamp = timeStamp1;
this.country = country1;
this.city = city1;
this.lat = lat1;
this.lng = lng1;
this.ad_id = ad_id1;
this.poster_id = poster_id1;
this.user_id = user_id1;
this.latLng = latLng1;
}
public AdViewed(){
this.timeStamp = 0 ;
this.country = "";
this.city = "";
this.lat = "";
this.lng = "";
this.ad_id = "";
this.poster_id = "";
this.user_id = "";
this.latLng = "";
}
public AdViewed(HashMap<String, ?> map){
this.timeStamp = 0;
this.country = "";
this.city = "";
this.lat = "";
this.lng = "";
this.ad_id = "";
this.poster_id = "";
this.user_id = "";
this.latLng = "";
if(!map.isEmpty()){
this.hydrate(map);
//erreurs = new ArrayList();
}
}
@Override
public int describeContents(){
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags){
dest.writeLong(timeStamp);
dest.writeString(country);
dest.writeString(city);
dest.writeString(lat);
dest.writeString(lng);
dest.writeString(ad_id);
dest.writeString(poster_id);
dest.writeString(user_id);

}
};

public long getTimeStamp() {

}
public void setTimeStamp(long timeStamp) {
this.timeStamp = timeStamp;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getLat() {
return lat;
}
public void setLat(String lat) {

}
public String getLng() {
return lng;
}
public void setLng(String lng) {

}
public String getAd_id() {
return ad_id;
}
public void setAd_id(String ad_id) {
this.ad_id = ad_id;
}
public String getPoster_id() {
return poster_id;
}
public void setPoster_id(String poster_id) {
this.poster_id = poster_id;
}
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getLatLng() {
return latLng;
}
public void setLatLng(String latLng) {
this.latLng = latLng;
}
}
我还有另一个来自AdViewed的课程AdInDeal。这是它的代码：
public class AdInDeal extends AdViewed {
protected String qte, costPerUnit, totalCost, imgPath;
protected boolean onCommand, onAcheteur, onVendeur;
protected int statutDeal;
public AdInDeal(AdInDeal adInDeal){
myInflation(adInDeal);
}
public void myInflation(AdInDeal adInDeal1){
this.setUser_id(adInDeal1.user_id);
this.setCostPerUnit(adInDeal1.getCostPerUnit());
this.setImgPath(adInDeal1.getImgPath());
this.setOnAcheteur(adInDeal1.isOnAcheteur());
this.setOnCommand(adInDeal1.isOnCommand());
this.setOnVendeur(adInDeal1.isOnVendeur());
this.setQte(adInDeal1.getQte());
this.setStatutDeal(adInDeal1.getStatutDeal());
this.setTotalCost(adInDeal1.getTotalCost());
this.setAd_id(adInDeal1.getAd_id());
this.setCity(adInDeal1.getCity());

this.setLat(adInDeal1.getLat());
this.setLng(adInDeal1.getLng());
this.setLatLng(adInDeal1.getLatLng());
this.setPoster_id(adInDeal1.getPoster_id());
this.setTimeStamp(adInDeal1.getTimeStamp());
}
public AdInDeal(long timeStamp1, String country1, String city1, String lat1, String lng1, String ad_id1, String poster_id1,
String user_id1, String latLng1, String qte1, String costPerUnit1, String totalCost1){
super(timeStamp1, country1, city1, lat1, lng1, ad_id1, poster_id1,
user_id1, latLng1);
this.qte = qte1;
this.costPerUnit = costPerUnit1;
this.totalCost = totalCost1;
this.imgPath = "";
this.onCommand = false;
this.onAcheteur = false;

}

String imgPath1, boolean onCommand1, boolean onAcheteur1, boolean onVendeur1, int statutDeal1){
super(timeStamp1, country1, city1, lat1, lng1, ad_id1, poster_id1,

this.qte = qte1;
this.costPerUnit = costPerUnit1;

public void setStatutDeal(int statutDeal) {

}
}
我还有Activity，我们称之为ActivityA。 ActivityA使用Intent转到其他活动（我们称之为ActivityB）。
以下是ActivityA的代码：
AdInDeal adInDeal = new AdInDeal(111111111, "Canada", "Torronto", "43.620595", "-79.376129", "id1", "poster_id1" , "user_id1", "43.620595, -79.376129", "10", "100", "1000", "imgPath1")
Intent intent = new Intent(activityA.this, activityB.class);
intent.putExtra("text1", "A small text");
intent.putExtra("text2", adInDeal);//If I delete this line I have no problem
startActivity(intent);
以下是ActivityB的代码：
Intent mIntent = getIntent();
if(mIntent != null){
String mText = mIntent.getStringExtra("text1");
AdInDeal mAdInDeal = mIntent.getParcelableExtra("text2");
Toast.makeText(this, mAdInDeal.getQte(), Toast.LENGTH_LONG).show();
}
当我编译并运行此代码时，我得到一个IllegalArgumentException。
根据调试器的不同，它来自以下行：
AdInDeal mAdInDeal = mIntent.getParcelableExtra("text2");
在ActivityB。
但是我发现问题实际上在ActivityA的行中：
intent.putExtra("text2", adInDeal);
为什么会这样？
