当在Android应用中使用Glide加载网络图片后，需要替换为从图库或相机获取的图像时，可能出现Glide加载的图片与新图像重叠的问题。解决方法包括在设置新位图前清空imageView的背景，然后使用`imageView.setImageBitmap()`。同时，通过Glide的`diskCacheStrategy(DiskCacheStrategy.NONE)`和`skipMemoryCache(true)`防止Glide缓存影响显示。

我有一个片段,首先使用Glide将图像设置为imageView(从互联网上获取图像网址).然后在点击图像视图时,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()获得的位图时.图像实际上设置但滑动重叠.我需要显示从相机/画廊捕获的图像.任何帮助表示赞赏,如果可以使用毕加索或任何其他图书馆完成,请提出建议.

以下是我到目前为止所尝试的内容

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);

}

另请注意,这与删除Glide的缓存不同
