Question

我正在尝试选择要注册的图像。当单击ImageView时，将为用户提供拍照或从他/她的画廊中进行选择的选择。当用户选择图库选项时，它将显示选定的图像。当用户选择相机选项时，ImageView不会显示图像。以下是我的OnActivityResult

代码

protected void onActivityResult(int requestCode, int resultCode, Intent imgdata) {
        super.onActivityResult(requestCode, resultCode, imgdata);
        if (requestCode == SELECT_IMAGE && resultCode == RESULT_OK && imgdata != null) {
            selectedimage = imgdata.getData();
            try {
                InputStream inputStream = getContentResolver().openInputStream(selectedimage);
                Bitmap yourselectedimage = BitmapFactory.decodeStream(inputStream);
                imgchild.setImageBitmap(yourselectedimage);

            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), "Hello", Toast.LENGTH_SHORT).show();
            }
        }
        if (requestCode == CAPTURE_IMAGE && resultCode == RESULT_OK && imgdata != null) {
            camImg =(Bitmap) imgdata.getExtras().get("img");
            try {
                imgchild.setImageBitmap(camImg);

            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(getApplicationContext(), "Hello", Toast.LENGTH_SHORT).show();
            }
        }
    }

ImageView应该显示从相机拍摄的照片。

Answer 1

我希望这对您有用。

像这样设置图片

    Bitmap photo = (Bitmap) data.getExtras().get("data");
    imageView.setImageBitmap(photo);


   // CALL THIS METHOD TO GET THE ACTUAL PATH
   Uri tempUri = getImageUri(getApplicationContext(), photo);
   File finalFile = new File(getRealPathFromURI(tempUri));
   Log.e("path", finalFile.getAbsolutePath());

获取图像存储路径

 public String getRealPathFromURI(Uri uri) {
            Cursor cursor = getContentResolver().query(uri, null, null, null, null);
            cursor.moveToFirst();
            int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
            return cursor.getString(idx);
        }

Answer 2

通过阅读代码，我认为GoogleAnalytics analytics = GoogleAnalytics.getInstance(this); Tracker tracker = analytics.newTracker(R.xml.global_tracker);很可能为空，因为从camImg提取位图的方式不正确。

Intent实现了Bitmap，因此您需要像这样提取它：

Parcelable

Answer 4

我遇到了与Android Marshmallow相同的问题，就我而言，这是由于位图过大导致的，所以我通过调整位图的大小来找出以下代码

'statusCode'

ImageView未显示使用Android中的相机捕获的图像
