如何通过开放的我们的活动与使用捆绑数组 [英] How to pass an array of Uri between Activity using Bundle

问题描述

我需要开放的阵列传递到另一个活动， 通过字符串数组我用简单的

I need to pass an array of Uri to another activity, to pass an array of String I use simply

String[] images=getImagesPathString();

    Bundle b = new Bundle();
    b.putStringArray("images", images);

但是用开放的阵列

But using an array of Uri

 Uri[] imagesUri=getImagesUri();

这不工作，因为没有在捆绑的方法putUri（URI X）

this doesn't works because there isn't a method "putUri(Uri x)" in Bundle

我怎么能解决这个问题？

How could I solve this problem?

推荐答案

您应该考虑的Parcelable界面，看看如何通过东西意向

You should look into the Parcelable interface to see how to pass things on an intent

http://developer.android.com/intl/ ES /参考/安卓/ OS / Parcelable.html

也许你可以实现实现该接口ParcelableUri类。

Maybe you can implement a ParcelableUri class that implements that interface.

这样的（未测试!!）：

Like this (not tested!!):

public class ParcelableUri implements Parcelable {

private Uri[] uris;

public ParcelableUri(Parcel in) {
    Uri.Builder builder = new Uri.Builder();

    int lenght = in.readInt();
    for(int i=0; i<=lenght; i++){           
        uris[i]= builder.path(in.readString()).build();
    }
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeInt(uris.length);
    for(int i=0; i<=uris.length; i++){
        dest.writeString(uris[i].toString());
    }
}

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

    public ParcelableUri createFromParcel(Parcel in) {
        return new ParcelableUri(in);
    }

    public ParcelableUri[] newArray(int size) {
        return new ParcelableUri[size];
    }
};
