So I have an application that users can take a picture and store it locally. The image name is stored in my SQLite database for future reference to call the photo. Right now I've traced the problem to setting the bitmap image to the imageview. Here's my code:
private void displayListView() {
// TODO Auto-generated method stub
Cursor cursor = info.getListData();
String[] listViewColumns = new String[] { Database.KEY_BREWNAME, Database.KEY_BREWERY, Database.KEY_RATING,
Database.KEY_DATEIMAGENAME, };
int[] dataToListView = new int[] { R.id.tvBrewName, R.id.tvBrewery, R.id.tvRating, R.id.ivThumb, };
dataAdapter = new SimpleCursorAdapter(this, R.layout.entrymain, cursor, listViewColumns, dataToListView, 0);
ViewBinder viewBinder = new ViewBinder() {
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
ImageView image = (ImageView)view;
Log.w(TAG, "******************List Image loaded == " + columnIndex + " **********************");
try {
FileInputStream fis = openFileInput(cursor.getString(columnIndex));
fis.close();
Log.w(TAG, "******************List Image loaded == fis.close **********************");
image.setImageBitmap(BitmapFactory.decodeStream(fis));
Log.w(TAG, "******************List Image loaded == setimage success **********************");
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return true;
};
};
ImageView image = (ImageView)findViewById(R.id.ivThumb);
viewBinder.setViewValue(image, cursor, cursor.getColumnIndex("date_image_name"));
dataAdapter.setViewBinder(viewBinder);
listview.setAdapter(dataAdapter);
The code works just fine with out the ViewBinder and by using log.w's I traced the problem to the image.setImageBitmap(BitmapFactory.decodeStream(fis)) and I don't quite understand why it won't set the image as I've used this code else where with great success. Any ideas on why it won't set, I see that it's something to do with java.io.IOException: read failed: EBADF (Bad file number) however how do I remedy this? Thank in advance!

You are trying to decode a bitmap from a closed InputStream. fis.close(); must be called after image.setImageBitmap(BitmapFactory.decodeStream(fis));
Also, you have to check in the setViewValue method if you are really setting the value to the ImageView:
ViewBinder viewBinder = new ViewBinder() {
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if (!(view instanceof ImageView) || view.getId() != R.id.ivThumb) {
return false;
}
// the rest of the code
};
};
And the last thing. You don't need to explicitly call viewBinder.setViewValue(image, cursor, cursor.getColumnIndex("date_image_name")); because SimpleAdapter will do it for you. Just remove this line and everything should work fine.
