I have a Button with a backround ressource that defines states and backgrounds
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/white" android:state_pressed="true" />
<item android:drawable="#color/gray" android:state_pressed="false" />
<item android:drawable="#color/white" android:state_selected="true" />
<item android:drawable="#color/gray" android:state_selected="false" />
</selector>
I also tried
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/white" android:state_pressed="true" android:state_selected="true" />
<item android:drawable="#color/gray" android:state_pressed="false" android:state_selected="false" />
</selector>
when pressed it does change colors, but when I apply btn.setSelected(true); nothing happens
any ideas ?
OK I got it,
for future people who will encounter this, this has solved it
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/white" android:state_pressed="true" />
<item android:drawable="#color/white" android:state_selected="true" />
<item android:drawable="#color/tab_gray" />
</selector>
Try btn.performClick();, which clicks the button. This might work:
void pressButton(Button btn, boolean pressed) {
if (pressed != btn.isPressed()) {
btn.performClick();
}
}

temp_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#color/color1" />
<item android:state_selected="true" android:color="#color/color2" />
<item android:color="#color/color3" />
</selector>
And I applied it through the code below
imageView.setImageResource(R.drawable.image)
ImageViewCompat.setImageTintList(imageView, ColorStateList.valueOf(R.color.temp_selector))
I don't know why it doesn't work... What should I do?
(It has to be applied programatically. not xml.)
Use below to change color
imageView.isSelected = true
imageView.isSelected = false
Use below selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/color3" android:state_selected="false" />
<item android:color="#color/color2" android:state_selected="true"/>
<item android:color="#color/color1" android:state_pressed="true" />
</selector>
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);
This is my selector:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#android:drawable/ic_delete"
android:state_enabled="false"
android:state_selected="false" />
<item android:drawable="#android:drawable/arrow_up_float"
android:state_selected="true"
android:state_enabled="true" />
<item android:drawable="#drawable/modosprepara"
android:state_enabled="true"
android:state_selected="false" />
</selector>
"arrow_up_float" and "modosprepara" works but "ic_delete" never appears.
I use this to disable this view:
tabs.getTabWidget().getChildAt(index).setEnabled(false);
You must have to follow the order.
1) state_enabled = true
2) state_enabled = false
3) state_pressed = true
4) state_pressed = false
I just found a solution
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/modosprepara"
android:state_activated="true"/>
<item android:drawable="#android:drawable/arrow_up_float"
android:state_selected="true" />
<item android:drawable="#android:drawable/ic_delete" />
</selector>
and
tabs.getTabWidget().getChildAt(index).setEnabled(false);
tabs.getTabWidget().getChildAt(index).setActivated(false);
Thanks for the answers !
I want to change the background of the button when the button is unclickable.I have used selector for that but it is not working in the case when the button remains unclickable.
This is the selector file:
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:drawable="#drawable/button_lightgrey" />
<item android:state_pressed="true" android:state_enabled="true" android:drawable="#drawable/button_blue"/>
<item android:state_focused="true" android:drawable="#drawable/button_darkgreen" />
<item android:drawable="#drawable/button_lightgreen" />
</selector>
This is the button where i am using this selector file:
<Button
android:id="#+id/PrevButton"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"
android:layout_marginLeft="5.0dip"
android:layout_weight="1.0"
android:background="#drawable/ibtn"
android:onClick="onPrevButtonClick"
android:text="Prev" />
Please help me.All other functions are working in the selector file but only the unclickable button case is not working.Thanks
instead of button.setClickable(false) do button.setEnabled(false) and use the same selector xml.
this may helps you
i think in your selector file having issue try selector file like below
pls change images as you require
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/img_btn_repeat_pressed"
android:state_focused="true"
android:state_pressed="true" />
<item android:drawable="#drawable/img_btn_repeat_pressed"
android:state_focused="false"
android:state_pressed="true" />
<item android:drawable="#drawable/img_btn_repeat_pressed" android:state_focused="true" />
<item android:drawable="#drawable/img_btn_repeat"
android:state_focused="false"
android:state_pressed="false" />
</selector>
Just modify your selectors with below selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
android:state_pressed="false" android:drawable="#android:color/transparent" />
<item android:state_focused="false" android:state_selected="true"
android:state_pressed="false" android:drawable="#drawable/round_corner_button_sort" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false"
android:state_pressed="false" android:drawable="#drawable/round_corner_button_sort" />
<item android:state_focused="true" android:state_selected="true"
android:state_pressed="false" android:drawable="#drawable/round_corner_button_sort" />
</selector>
Hope this helps you.
Edit
As per your comments you can't use selector for button which is the state as false(button.setclickable(false);) In this state you can't use your selector
I'm using this code sheet to define textView's color in different events. The textView is in listView (10+ items) and the effect (color) applies on every textView in every listItem. How I can change color of only textView that is pressed?
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_focused="true"
android:state_pressed="true"
android:color="#color/text_white" />
<item
android:state_focused="false"
android:state_pressed="true"
android:color="#color/text_white" />
<item
android:state_focused="true"
android:color="#color/text_white" />
<item
android:state_selected="true"
android:color="#color/text_white" />
<item
android:state_checked="true"
android:color="#color/text_white" />
<item
android:state_selected="false"
android:state_checked="false"
android:state_focused="false"
android:state_pressed="false"
android:color="#color/text_blue" />
</selector>
try this
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" //<<<<<Here focus us true then txt_pressed
android:state_pressed="false"
android:drawable="#drawable/txt_pressed" />
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/txt_pressed" />
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/txt_pressed" />
<item android:drawable="#drawable/txt_default" />
</selector>
In the xml file, to the textview you want to change color, add
android:background="#drawable/filename"
