java - 微信android sdk 能否一次发送多张图片？

Question

WXImageObject imgObj = new WXImageObject();
imgObj.setImagePath(path);

WXMediaMessage msg = new WXMediaMessage();
msg.mediaObject = imgObj;

Bitmap bmp = BitmapFactory.decodeFile(path);
Bitmap thumbBmp = Bitmap.createScaledBitmap(bmp, THUMB_SIZE, THUMB_SIZE, true);
bmp.recycle();
msg.thumbData = Util.bmpToByteArray(thumbBmp, true);

SendMessageToWX.Req req = new SendMessageToWX.Req();
req.transaction = buildTransaction("img");
req.message = msg;
req.scene =  SendMessageToWX.Req.WXSceneTimeline ;
api.sendReq(req);

以上代码可以分享一张图片到微信朋友圈，但是如果 想要一次分享多张图片怎么办啊

不能，至少目前這個ＳＤＫ版本是不能處理多個圖片。 SDK沒有混淆，透過觀看，它支援

public static final int TYPE_UNKNOWN = 0;
public static final int TYPE_TEXT = 1;
public static final int TYPE_IMAGE = 2;
public static final int TYPE_MUSIC = 3;
public static final int TYPE_VIDEO = 4;
public static final int TYPE_URL = 5;
public static final int TYPE_FILE = 6;
public static final int TYPE_APPDATA = 7;
public static final int TYPE_EMOJI = 8;

SDK 透過Bundle來傳遞數據，用<key,value>記錄每種數據類型，並且都是單一的記錄，如圖片數據WXImageObject ：

paramBundle.putByteArray("_wximageobject_imageData", this.imageData);
paramBundle.putString("_wximageobject_imagePath", this.imagePath);
paramBundle.putString("_wximageobject_imageUrl", this.imageUrl);

只有單一的 imageData ，死心吧。

不過，網路上有個方法是透過系統的「分享」來呼叫微信，以下是我寫的程式碼測試有效，不過這種方法還得手工在微信裡面操作，適用範圍太小：

private void shareMultiplePictureToTimeLine(File... files) {
    Intent intent = new Intent();
    ComponentName comp = new ComponentName("com.tencent.mm",
            "com.tencent.mm.ui.tools.ShareToTimeLineUI");
    intent.setComponent(comp);
    intent.setAction(Intent.ACTION_SEND_MULTIPLE);
    intent.setType("image/*");

    ArrayList<Uri> imageUris = new ArrayList<Uri>();
    for (File f : files) {
        imageUris.add(Uri.fromFile(f));
    }
    intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, imageUris);

    startActivity(intent);
}

            // 遍歷 SD 卡下 .png 檔案透過微信分享
            File root = Environment.getExternalStorageDirectory();
            File[] files = root.listFiles(new FileFilter() {

                @Override
                public boolean accept(File pathname) {
                    if (pathname.getName().endsWith(".png"))
                        return true;
                    return false;
                }
            });
            shareMultiplePictureToTimeLine(files);
