ListView setBackgroundResource无法正常工作

Question

I have problem wit changing backgroud color in my project. I'm just trying to change list background color with condition in ViewBinder. But color of backgroung didn't changing.

My ViewBinder

public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
LinearLayout ll = (LinearLayout) findViewById(R.id.listViewTopLinearLayout);
String voted = cursor.getString(VOTED_COLLUMN_INDEX);

    if (columnIndex == cursor.getColumnIndex(AssetsTableHelper.COLUMN_VOTED)) {
        boolean is_checked = voted.equals("true");
        if (is_checked) {
            ((View) ll.getParent()).setBackgroundResource(R.color.votedColor);
                ((View) view.getParent()).setBackgroundResource(R.color.votedColor);
        } else {
            ((View) view.getParent()).setBackgroundResource(R.color.notVotedColor);
        }
        return true;
    }
    return false;
};

onCreate

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
integrator = new IntentIntegrator(this);
datasource = new AssetsDataSource(this);
Cursor cursor = datasource.getCursorForAllAssets();
adapter = new SimpleCursorAdapter(this, R.layout.listview_item_row,cursor, UI_BINDING_FROM,UI_BINDING_TO, 0);
adapter.setViewBinder(new CustomViewBinder());
setListAdapter(adapter);

List_item_row.xml

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/tvSurname"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:textColor="#000000"
        android:textSize="20sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tvName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:textColor="#000000"
        android:layout_marginLeft="5dp"
        android:textSize="20sp"
        android:textStyle="bold" />
</LinearLayout>

<TextView
    android:id="@+id/tvHomeNumber"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:textColor="#000000"
    android:textSize="15sp"
    android:textStyle="bold" />

I think, problem is in argument of setBackgroundResource(R.color.votedColor). Argument should be a resource id for example some R.drawable.votedColor. Take a look setBackgroundResource and to make a drawable xml file take a look at Drawable Resource .
