使用"com.android.camera.action.TRIM"进行视频修剪(Gallery2包)

Question

我需要通过Video实现修剪操作.我正在使用此代码,它在Gallery2软件包安装的手机上完美运行.但它没有返回onActivityResult(如果攻击成功,意图不会返回任何结果).

码:

Intent trimVideoIntent = new Intent("com.android.camera.action.TRIM");

            // The key for the extra has been discovered from com.android.gallery3d.app.PhotoPage.KEY_MEDIA_ITEM_PATH
            trimVideoIntent.putExtra("media-item-path", FilePath);
            trimVideoIntent.setData(videoUri);

            // Check if the device can handle the Intent
            List<ResolveInfo> list = getPackageManager().queryIntentActivities(trimVideoIntent, 0);
            if (null != list && list.size() > 0) {
                startActivityForResult(trimVideoIntent,2); // Fires TrimVideo activity into being active
            }else {
                Toast.makeText(this, "Video trimming not supported", 1).show();
            }

有没有办法在修剪和返回结果后关闭gallery2？
