我尝试了很多在这里和其他网站上找到的解决方案 - 但我就是无法让它工作!
我在一个活动中有一个“公寓”对象,该对象将在另一个活动中使用。 该活动是从MyMapOverlayItem类启动的,应启动ApartmentInfoActivity,在其中应使用Apartment对象。
MyMapOverlayItem.java:
package com.android.madsoft.spotter;
import java.util.ArrayList;
import android.content.Context;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class MyMapOverlayIcon extends ItemizedOverlay<OverlayItem> {
Context mContext;
ArrayList<Apartment> myList;
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
public MyMapOverlayIcon(Drawable defaultMarker) {
super(defaultMarker);
}
public MyMapOverlayIcon(Drawable defaultMarker, Context context, ArrayList<Apartment> myList) {
super(boundCenterBottom(defaultMarker));
mContext = context;
this.myList = myList;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
@Override
protected boolean onTap(int index) {
Apartment ap = myList.get(index);
ApartmentParcel ap1 = new ApartmentParcel(ap);
Intent i = new Intent(mContext, ApartmentInfoActivity.class);
Bundle b = new Bundle();
b.putParcelable("app", ap1);
i.putExtras(b);
// i.putExtra("app",ap1);
// b.putSerializable("apartment", ap);
// WHAT TO DO!?
mContext.startActivity(i);
return true;
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
return mOverlays.size();
}
}
