java - 广播时Android位图包裹解码错误

Question

我有一个 Parcelable 联系人对象。我需要将它们放在 ArrayList 中并将其广播到 Activity。在广播监听器中读取 ArrayList 时出错。我尝试了很多来解决这个问题。但找不到任何解决方案来修复它。

错误:

服务

contactResIntent.putParcelableArrayListExtra("clist", contactList);

广播监听器

private BroadcastReceiver contactsReceiver = new BroadcastReceiver() {

            //Toast.makeText(getApplicationContext(),"GOT Contacts response from service!!!",Toast.LENGTH_SHORT).show();

            ArrayList<Contact> clist =  intent.getParcelableArrayListExtra("clist");
            if(clist != null){
                String s = clist.get(0).getClass().toString();
                Log.d("@HomeActivity","CONTACTS LIST :"+s+"##"+String.valueOf(clist.size()));
            }

首先，您应该避免将位图放入包中。它通常使用大量内存，我经历过一些 TransactionTooLargeException传输大型 parcelables 时(限制为 1Mb)。相反，您可以只编写一个 String 或代表该缩略图的标识符，并在需要时再次加载它。

话虽如此，您可以尝试以下操作(检查是否为空)。

改变构造函数:

protected Contact(Parcel in) {
    id = in.readString();
    lookupKey = in.readString();
    dispName = in.readString();
    email = in.readString();
    mobileNo = in.readString();
    if (in.readByte() == 1) {
        photoThumbnail = (Bitmap) in.readParcelable(Bitmap.class.getClassLoader());
    }
    statusMsg = in.readString();
    isRapo = in.readInt();
}

改变writeToParcel

public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(id);
    dest.writeString(lookupKey);
    dest.writeString(dispName);
    dest.writeString(email);
    dest.writeString(mobileNo);
    if (photoThumbnail != null){
        dest.writeByte((byte) 1);
        dest.writeParcelable(photoThumbnail,flags);
    } else {
        dest.writeByte((byte) 0);
    }
    dest.writeString(statusMsg);
    dest.writeInt(isRapo);
}
