Question

How do i do it? i’ve searched and looked and still haven’t found anything usefull for me.

I currently have 2 arraylist.
first one includes Strings of calculations i got from a previous activity.
second one includes Doubles of results of the above mentioned calculations i got from a previous acitivty.

I’ve saved both Arraylists in SQLLITE database.

The best i got so far is:

inside onCreate:

SimpleAdapter adapter = new SimpleAdapter(this, list,
            R.layout.custom_row_view,
            new String[] { "operationName", "operationValue" }, new
                            int[] { R.id.text1,R.id.text2 });
populateList();
setListAdapter(adapter);

inside a function – populateList(); :

static final ArrayList<HashMap<String, Double>> list = new ArrayList<HashMap<String, Double>>();

private void populateList() {

HashMap<String, Double> temp = new HashMap<String, Double>();
for (int i = 1; i <= 20; i++) {
    temp.put(operationNames.get(i), operationValues.get(i));
}

list.add(temp);
}

EDIT:
The custom_row_view .xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/tv1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#CBC300"
    android:textSize="16sp"
    android:textStyle="bold" />

<TextView
    android:id="@+id/tv2"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#3200A3"
    android:textSize="16sp"
    android:textStyle="bold" />

</LinearLayout>

What am i missing here? it keeps crashing when entering this specific listactivity.

Any help will be really appreciated.

Answer 1

in your code you try to get third element from list of 2 elements! You can set some default values to this list or show only 2 items.
