I want to change background of a button when it is clicked. I tried to use a selector. But It didn't work. Here is the selector (add_grp_slctr.xml):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="@drawable/add_grp_d"/>
<item android:state_pressed="true" android:drawable="@drawable/add_grp_d" />
<item android:drawable="@drawable/add_grp" />
</selector>
And the button :
<Button
android:id="@+id/addGrpBtn"
android:layout_width="55dp"
android:layout_height="45dp"
android:layout_gravity="center"
android:background="@drawable/add_grp_slctr"
android:onClick="addGrpDialogOpen" />
add_grp_d and add_grp are images(png).
I tried a similar code which will be white by default, black when pressed on an onclick of a button:
// * * *This is the btn_selector which is to be declared in drawable folder***
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="@android:color/black" /> <!-- pressed -->
<item android:drawable="@android:color/white" /> <!-- default -->
</selector>
and called this on the button.xml -->
android:background="@drawable/btn_selector"
Hope this would help..:)
go through the http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList once. Also state_focussed for button only works when you are focussing the button using a hardware-keyboard. As for your case
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="false" android:state_selected="false" android:drawable="@drawable/button_default"/>
<item android:state_pressed="true" android:state_selected="false" android:drawable="@drawable/button_default" />
<item android:state_pressed="false" android:state_selected="true" android:drawable="@drawable/button_selected"/>
<item android:state_pressed="true" android:state_selected="true" android:drawable="@drawable/button_selected" />
<item android:drawable="@drawable/button_selected" />
</selector>
Use your selector
change your code like this
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_focused="true" android:drawable="@drawable/add_grp_d"/>
<item android:state_pressed="true" android:drawable="@drawable/add_grp" />
<item android:drawable="@drawable/add_grp_d" />
</selector>
My Code
<item android:drawable="@drawable/shadow_design_click" android:state_pressed="true"/>
<item android:drawable="@drawable/shadow_design" android:state_focused="true"/>
<item android:drawable="@drawable/shadow_design"/>
</selector>
I think you should change your selector a bit. Check this answer here .
Instead of passing cuastom XML file, if you just want to change the color of you button then you can try with the following way.
Button lineColorCode = (Button)findViewById(R.id.button1);
Now inside button's click event use following code.
int color = Color.parseColor("#AE6118"); //The color u want
lineColorCode.setColorFilter(color);
