Android：在Java中更改“选定列表项”的TEXT颜色

Question

I am working on a dynamic Android application in Java where a list view gets values from database.

What I am looking for is how to change the TEXT color of Selected list Item in that list, and the color of that text should remain changed to indicate that this item has been selected, no matter if the activity has been changed. Whenever we come back to that activity to make another selection, that color changing item should be there still with the changed Text color.

Answer 1

When you select an item, you will need to save that information in a static data structure. If you want the selection to be persistent (even if the app is closed), then you will need to store the selection indicator in your database. When you read your database to extra the data, use the "selection indicator" in your adapter to decide what color to use.

Simply changing the textColor of your textField will not persist when you return to that activity.
