Android 5.0 Lollipop: setColorFilter "leaks" onto other buttons -

i using setcolorfilter set color filter of 1 of button. has been working until android 5.0 lollipop update. now, color filter seems leak onto other buttons, when close activity , reopen (it resets if close app , reopen).

my styles.xml (v21): (same older except here parent material, before holo)

<style name="theme.fullscreen" parent="@android:style/theme.material.light.noactionbar.fullscreen">     <item name="android:buttonstyle">@style/standardbutton</item>     <item name="android:windowtranslucentstatus">true</item> </style> 

my styles.xml (for versions):

<style name="standardbutton" parent="android:style/widget.button">     <item name="android:background">@android:drawable/btn_default</item> </style> 

my button:

<button     android:id="@+id/mainmenubutton"                   android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:onclick="mainmenu"     android:text="@string/button_mainmenu"     android:visibility="gone" /> 

my code:

button mainmenubutton = (button) findviewbyid(r.id.mainmenubutton); mainmenubutton.getbackground().setcolorfilter(new porterduffcolorfilter(getresources().getcolor(r.color.light_green), porterduff.mode.multiply)); mainmenubutton.setvisibility(view.visible); 

the color:

<color name="light_green">#5cd65c</color> 

the result:

i open app, game activity , buttons displaying correctly. press button set color filter, go main menu , reopen game activity , buttons green.

any ideas?

the problem background drawable reused across many views. ensure drawable not shared between multiple views should use mutate method.

see: mutate()

example code:

drawable background = mainmenubutton.getbackground(); background.mutate(); background.setcolorfilter(new porterduffcolorfilter(getresources().getcolor(r.color.light_green), porterduff.mode.multiply)); mainmenubutton.setbackground(background);
