Image captured from camera not displaying in imageview android

问题

I have a problem, that when i have taken an image from camera, image not displaying in imageview.

I created the code by referring the following link

http://developer.android.com/training/camera/photobasics.html

I am posting my code, please have a look,

public  void takeImage(View v) {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
        File photoFile = null;

        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
        }

        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
}

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "sample_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();

    galleryAddPic();

    return image;
}

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    try {
        if (requestCode == REQUEST_IMAGE_CAPTURE) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            mImageView.setImageBitmap(imageBitmap);
        }
    }catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG).show();
    }
}

The image captured is storing in SDcard. But not showing in imageview.

Where i have gone wrong. I have tried a lot. But no result. Is there any way to solve this issue.

回答1:

this works for me:

Bitmap myBitmap = BitmapFactory.decodeFile(imagePath);
image.setImageBitmap(myBitmap);

回答2:

You don't need to create the temp file, just put the Uri in the intent. After the capture, check the file existence of that Uri. If it exists, capture has been done successfully.
