Here we go. I have a button that has a non-pressed state background as transparent. As soon as the button is pressed, the background is no longer transparent (see the pics). I use nine patch for all my images.
This is my selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/starfighterstartbtndown" android:state_pressed="true"/>
<item android:drawable="@drawable/starfighterstartbtn"/>
</selector>
And here is the layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/mainMenuImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:src="@drawable/starfighter" >
</ImageView>
<RelativeLayout
android:id="@+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"
android:orientation="horizontal" >
<ImageButton
android:id="@+id/btnStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:background="@android:color/transparent"
android:clickable="true"
android:hapticFeedbackEnabled="true"
android:src="@drawable/startselector" >
</ImageButton>
<ImageButton
android:id="@+id/btnExit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:clickable="true"
android:src="@drawable/exitselector"
android:background="@android:color/transparent"
android:hapticFeedbackEnabled="true" >
</ImageButton>
</RelativeLayout>
Not Clicked:
Clicked:
I have also tried the following methods with no luck
button.getBackground().setAlpha(0);
button.setBackgroundColor(Color.TRANSPARENT);
Also tried the following inside the onClickListener()
view.getBackground().setAlpha(0);
view.setBackgroundColor(Color.TRANSPARENT);
button.getBackground().setAlpha(0);
button.setBackgroundColor(Color.TRANSPARENT);
Still no luck. Good luck :)
to make your button's background transparent in non pressed state , your selector should be like this :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/starfighterstartbtndown" android:state_pressed="true"/>
<item android:drawable="@android:color/transparent"/>
</selector>
And in your imageButton's declaration in xml should use the selector as a background and dont make anything as a source of your imageButton:
<ImageButton
android:id="@+id/btnStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:src="@drawable/startselector"
android:background="@android:color/transparent"
android:clickable="true"
android:hapticFeedbackEnabled="true" />
