Images in ListView over SimpleAdapter are not updatet after change

Question

I have a list-activity using a row-based layout for elements of the list:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView android:id="@+id/exerciseText" android:textSize="40sp" android:layout_weight="1" android:layout_width="wrap_content" android:layout_height="wrap_content"></TextView>
<ImageView android:id="@+id/solutionImage" android:scaleType="center" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> 
</LinearLayout>

I fill the list with a SimpleAdapter and provide the data over this List:

List<HashMap<String, String> > data;

I initially load the data with some strings and default image. The main images are loaded later. The images are saved as resource ids

Integer.toString(R.drawable.check)

Now the problem: While the images I initially put into the list are loading properly, updated items don't change their appearance directly. They have to be out of the viewable area(In the scrolled view I have to scroll until they are out of the window. If I scroll them back they changed their appearance). This problem does not only concern to images but also on texts(which I don't update in my App).

Do I have to use an ArrayAdapter rather than a SimpleAdapter to get automatically updating work?

Thanks for tips in any kind and please ask if I didn't make myself clear

Answer 1

A SimpleAdapter is

An easy adapter to map static data to views

thus if your data is subjected to changes in the future, you should use an ArrayAdapter. In the latter, after updating the data call

mArrayAdapter.notifyDataSetChanged();

and the images should update automatically

PS. Same question

Answer 2

SimpleAdapter also supports the method notifyDataSetChanged(), so no need to use a ArrayAdapter
