How to Maintain Highlight Persistence for Selected Items in Android ListView?

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>
Copy after login

Solution

To ensure the selected item in cli_lista remains highlighted:

  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

    or programmatically:

    listView.setSelector(getResources().getDrawable(R.drawable.selector_background));
    Copy after login
