Android ListView Selected Item Highlight Persistence

Issue

In an Android application with two ListViews, the goal is to keep the selected item in one ListView highlighted while displaying the details of the selected item in the other ListView.

XML Structure

<ListView
    android:id="@+id/cli_lista"
    android:choiceMode="singleChoice"
    android:listSelector="#666666"
    ...>
</ListView>

<ListView
    android:id="@+id/cli_lista_det"
    ...>
</ListView>

Solution

1. Set the Choice Mode programmatically:

   listView.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);

   Copy after login

2. Specify the background color for selected items:

   android:listSelector="#666666"

   Copy after login
