如何从Android的摄像头的缩略图和图像路径？ [英] How to get thumbnail and image path from android camera?

问题描述

通过这样的方式

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, REQUEST_CODE);

我得到了一个的onActivityResult位表格式的意图，而不是路径！，通过这样的方式

i get a bitmap form intent in the onActivityResult, and not the path !, by this way

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
startActivityForResult(intent, REQUEST_CODE);

我可以从意向的路径，而不是位图!!，我怎么能得到位图（缩略图）和Android的相机路径？

i can get the path from intent, and not the bitmap !!, how can i get the bitmap(thumbnail) and the path from android camera ?

推荐答案

这是你可以使用该路径创建一个这样的缩略图图像路径

From that you can get the image path with using that path create a thumbnail image like this

/**
 * 
 * Returns the given size of the bitmap
 * 
 * @param path
 * @return {@link Bitmap}
 */
private Bitmap getThumbnailBitmap(String path, int thumbnailSize) {
    BitmapFactory.Options bounds = new BitmapFactory.Options();
    bounds.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(path, bounds);
    if ((bounds.outWidth == -1) || (bounds.outHeight == -1)) {
        return null;
    }
    int originalSize = (bounds.outHeight > bounds.outWidth) ? bounds.outHeight
            : bounds.outWidth;
    BitmapFactory.Options opts = new BitmapFactory.Options();
    opts.inSampleSize = originalSize / thumbnailSize;
    return BitmapFactory.decodeFile(path, opts);
}

给大小你要多少
