Android 从gallery中拾取图像并显示后，AlertDialog中的ImageView为空 （这是一个对话框，它显示了我试图在我的自定义对话框中从图库中显示所选图像到 IVIEVIEW 的对话框，但是 IVIEVIEW 出现空白。虽然它不是NULL。下面是下面的代码片段： public void loadImagefromGallery(View view) { Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, SELECT_PHOTO); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); try { if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK && null != data) { Uri selectedImage = data.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 picturePath = cursor.getString(columnIndex); cursor.close(); final Dialog dialog = new Dialog(SelectImagesActivity.this); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.upload_image); ImageView imageView = (ImageView) dialog.findViewById(R.id.imageView1); imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); EditText editText = (EditText)dialog.findViewById(R.id.keyWords); Button button = (Button)dialog.findViewById(R.id.done); dialog.setCancelable(false); dialog.getWindow().setLayout(550, 900); dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); dialog.show(); imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); } else { Toast.makeText(this, "You haven't picked Image", Toast.LENGTH_LONG).show(); } } catch (Exception e) { Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG) .show(); } }

任何帮助都将不胜感激。谢谢。

更改

 dialog.show();
 imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

到

改变

 dialog.show();
 imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

到

改为：

imageView.setImageURI(Uri.parse(picturePath));

改为：

imageView.setImageURI(Uri.parse(picturePath));

共享屏幕截图。Is

String picturePath=cursor.getString（columnIndex）；

返回图像的正确绝对路径。共享屏幕截图。Is
