this is my selector_txt.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:color="@color/Darkgoldenrod"/>
<item android:state_pressed="true" android:state_enabled="false"
android:color="@color/Darkgreen" />
<item android:state_enabled="false" android:color="@color/Red" />
<item android:color="@color/blue"/>
and this is my main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/hello"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
android:textSize="30dp"
android:textStyle="bold"
android:duplicateParentState="true"/>
You can also set your color in the xml if you want. Just create a color folder in your res folder and move the xml file there then you can set it via android:textColor="@color/selector_txt"
Regards the problem you're having. Android will always use the first match in a selector. If a TextView is pressed it is also focused. So add android:pressed="false"
to your first item or move the line after the pressed status line.
That's the full xml:
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_enabled="false" android:color="@color/Red" /> <item android:state_pressed="true" android:color="@color/Darkgreen" /> <item android:state_focused="true" android:color="@color/Darkgoldenrod"/> <item android:color="@color/blue"/> </selector>
