How to change text color on press of a particular textview in a linearlayout

问题

I have a Linear layout with 3 text views. I want to change the text view's font color when any of the text view is selected. I would like to retain the new color until another text view is selected. Basically this linear layout should mimic check box's selection behavior. I would like to use the selector to change the color of the text view's font color.

I used the below selector on text view's textColor and this only changes the font color as long as the text view is pressed

 android:textColor="@drawable/selector_header_text"

xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true" android:color="@color/blue"></item>
    <item android:state_focused="true" android:color="@color/blue"/>
    <item android:color="@color/light_gray"></item>

</selector>

How can I make my text views in linear layout to retain text color as long as its selected and not just pressed ?

回答1:

add the code android:state_selected="true" to your selector file

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true" android:color="@color/blue"></item>
    <item android:state_focused="true" android:color="@color/blue"/>
    <item android:state_selected="true" android:color="@color/blue"/>
    <item android:color="@color/light_gray"></item>

</selector>

In your class file add the following code,

textView.setselected(true);

Use android:state_checked, in addition or instead of android:state_pressed.
