Question

我正在尝试在用户点击的那一点上显示相机拍摄的图像的标记（缩略图）的全尺寸图像。但到目前为止，图像已显示，但始终显示最新拍摄的图像，而不是点击第一个标记时拍摄的图像。

到目前为止，这是我的代码：

public void onMapLongClick(final LatLng point) {
      poinOnMap=point;

      googleMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {

          @Override
          public void onInfoWindowClick(Marker marker) {
              Intent intent = new Intent();
              intent.setAction(Intent.ACTION_VIEW);
              Uri selectedImage = intent.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                Cursor cursor = getContentResolver().query(
                                   selectedImage, filePathColumn, null, null, null);
                cursor.moveToFirst();
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String fileUri = cursor.getString(columnIndex);
                cursor.close();
                bitmap = BitmapFactory.decodeFile(fileUri);
                Uri imgUri = Uri.parse("file://" + bitmap + fileUri);
                intent.setDataAndType(imgUri, "image/*");
                startActivity(intent);
            return;
          }
      });
     getApplicationContext().getDir(
              getResources().getString(R.string.app_name), MODE_PRIVATE);

          fileUri = Uri.fromFile(new File((Environment.getExternalStorageDirectory() +
                  "/" +getResources().getString(R.string.app_name)),new Date().getTime() + ".jpg"));
          Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
          takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
          startActivityForResult(takePictureIntent,TAKE_PICTURE);
  }

       public void onActivityResult(int requestCode, int resultCode, Intent data) {
          if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {

                  try {
                      GetImageThumbnail getImageThumbnail = new GetImageThumbnail();
                      bitmap = getImageThumbnail.getThumbnail(fileUri, this);
                  } catch (FileNotFoundException e1) {
                      e1.printStackTrace();
                  } catch (IOException e1) {
                      e1.printStackTrace();
                  }

有谁能告诉我我做错了什么？

Uri selectedImage为空

Intent intent = new Intent();
          intent.setAction(Intent.ACTION_VIEW);
          Uri selectedImage = intent.getData();

点击相机意图拍摄的各种标记时，如何显示图像？
