Ausnahme android.content.res.Resources $ NotFoundException: Datei-res/ziehbar/my.xml von ziehbar Ressource ID

Question

Was ist falsch mit diesem xml, Ich versuche, eine Taste drücken Gefühl dafür zu bekommen. Ich bekomme eine Ausnahme, ich kann es nicht verstehen. ResourceNotFound

In meinem layout.xml

<Button 
    android:id="@+id/submit" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:background="@drawable/submitbuttonpress" 
    android:text="Submit" 
    android:textColor="#eeeee4" 
    android:typeface="monospace" /> 

Mein submitbuttonpress.xml im ziehbar Ordner

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_pressed="false" android:background="#AAAAAA" /> 
    <item android:state_pressed="true" android:background="#777777" /> 
</selector> 

Exception (logcat)

Answer 1

Sobald Versuchen Sie, diese

In Wähler Zustand ist es erforderlich, ziehbar hinzufügen und in Ihrem Fall möchte, dass Sie Farbe hinzufügen in der Wahl state.So es möglich ist, drawable mit Farbe in Ressource zu erstellen. Es funktioniert wie ColorDrawable

Überprüfen Sie bitte unten Code

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

     <item android:drawable="@drawable/clr_normal" android:state_pressed="false"/> 
     <item android:drawable="@drawable/clr_pressed" android:state_pressed="true"/> 

    </selector> 

Werte/string.xml für Farbe

<drawable name="clr_normal">#AAAAAA</drawable> 
<drawable name="clr_pressed">#777777</drawable> 

Answer 2

Das Attribut android:background existiert nicht. Der richtige Weg, dies zu tun ist, um zuerst eine neue Ressourcendatei res/colors.xml mit folgendem Inhalt:

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <color name="lt_gray">#AAAAAA</color> 
    <color name="dk_gray">#777777</color> 
</resources> 

nur auf die folgende Ihre selector Ändern Sie dann:

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_pressed="false" android:drawable="@color/lt_gray" /> 
    <item android:state_pressed="true" android:drawable="@color/dk_gray" /> 
</selector> 

Diese erstellt automatisch eine ColorDrawable und Abtretungs es als der ziehbare für diesen Staat.
