删除由Glide设置的图像，并使用imageView.setImageBitmap（）

Question

我有一个片段，其中首先使用Glide（从互联网获取的图像网址）将Image设置为imageView。然后，在图像视图上单击时，可以从图库或相机意图中选择新图像。问题是当我尝试设置从OnActivityResult（）获取的位图时。图像实际已设置，但被滑行重叠。我需要显示从相机/画廊捕获的图像。感谢您提供任何帮助，如果可以使用Picasso或任何其他库来完成，请提出建议。以下是我到目前为止尝试过的

onActivityResult（）

 @Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == Activity.RESULT_OK)
    {
        if (requestCode == SELECT_FILE)
            onSelectFromGalleryResult(data);
        else if (requestCode == REQUEST_CAMERA)
            //   onCaptureImageResult((Bitmap) data.getExtras().get("data"));
            onCaptureImageResult(data);
    }
}

private void onCaptureImageResult(Intent data)
{
    if (data != null)
    {
        mImageUri = Uri.parse("file://" + data.getStringExtra(CameraConfiguration.Arguments.FILE_PATH));
    }

    try
    {
        bitmap_image = MediaStore.Images.Media.getBitmap(mContext.getContentResolver(), mImageUri);
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap_image.compress(Bitmap.CompressFormat.JPEG, 60, bytes);

        bitmap_image = Bitmap.createScaledBitmap(bitmap_image, (int) (bitmap_image.getWidth() * 0.5), (int) (bitmap_image.getHeight() * 0.5), true);

        ExifInterface ei = new ExifInterface(data.getStringExtra(CameraConfiguration.Arguments.FILE_PATH));
        int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);

        switch (orientation)
        {
            case ExifInterface.ORIENTATION_ROTATE_90:
                bitmap_image = (SnappyUtils.rotateImage(bitmap_image, 90));
                break;

            case ExifInterface.ORIENTATION_ROTATE_180:
                bitmap_image = (SnappyUtils.rotateImage(bitmap_image, 180));
                break;

            case ExifInterface.ORIENTATION_ROTATE_270:
                bitmap_image = (SnappyUtils.rotateImage(bitmap_image, 270));
                break;

            case ExifInterface.ORIENTATION_NORMAL:

            default:
                break;
        }
    }
    catch (IOException e)
    {
        e.printStackTrace();
        Log.d("exception", e.toString());
    }
    ////////////////////// it is showing on iv_logo2 as expected as it does not has anything set by glide//////////////////////////////////////////////////////////////////
    iv_logo.setBackground(null);
    iv_logo.setImageBitmap(bitmap_image);
    iv_logo2.setImageBitmap(bitmap_image);

    ///////////////////////////tried added this by seeing other SO posts //////////////////////////////////////////////////////////////////
    Glide.with(mContext)
            .load(mImageUri)
            .signature(new StringSignature(String.valueOf(System.currentTimeMillis())))
            .diskCacheStrategy(DiskCacheStrategy.NONE)
            .skipMemoryCache(true)
            .into(iv_logo);
}

还请注意，这与删除Glide缓存不同

Answer 1

用：

Glide.with(iv_logo.context)
    .clear(iv_logo);

Answer 2

在花了很多时间弄清楚如何删除 Glide 设置的图像但失败后，决定采用老式方法，首先在手机中下载图像，然后在我的应用程序中将该图像设置为位图

异步任务下载图像

private class GetImages extends AsyncTask<Object, Object, Object>
{
    private String requestUrl, imagename_;
    private ImageView view;
    private Bitmap bitmap;
    private FileOutputStream fos;

    private GetImages(String requestUrl, ImageView view, String _imagename_)
    {
        this.requestUrl = requestUrl;
        this.view = view;
        this.imagename_ = _imagename_;
    }

    @Override
    protected Object doInBackground(Object... objects)
    {
        try
        {
            URL url = new URL(requestUrl);
            URLConnection conn = url.openConnection();
            bitmap = BitmapFactory.decodeStream(conn.getInputStream());
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Object o)
    {
        view.setImageBitmap(bitmap);
    }
}
