change toggle button text color through xml - android

Hi i'm trying to change the color of toggle button's text through xml.
I have referred links but its only changing the background color of toggle button but not its text.
I tried with this approach :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#ffffff" />
<item android:state_checked="false" android:color="#000000" />
</selector>
but only the background is changing.
Note : I don't want to do it in code since there are 21 toggle buttons and setting listeners for each of them is not good.

You shouldn't set the parent of a widget style to be a theme. Instead, you'll want to set it to be the default widget style that you want to modify (e.g. #android:style/Widget.Holo.Button.Toggle).
In your case, however, you don't need to use a style:
res/color/toggle_text.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:color="#ffffff" />
<item android:color="#000000" />
</selector>
res/layout/your_layout.xml:
...
<ToggleButton
android:id="#+id/toggleButton"
...
android:textColor="#color/toggle_text" />

android checkbox text disappears when custom background is set

I want to make a weekly calendar, where every day is a custom checkbox with objective to look like the image bellow:
(http://i.imgur.com/WjIKCd0.png)
When the user clicks on a day (Monday in this case), the "background" and "button" checkbox changes as well the text color...
I made the drawables and it seems to work fine... check bellow the code:
Checkbox layout:
<CheckBox
android:id="#+id/selectMonday"
android:layout_width="40dp"
android:layout_height="40dp"
android:button="#drawable/ic_none"
style="#style/CheckBoxBackgroundView"
android:onClick="selectDay"
android:text="#string/monday_letter"
android:gravity="center"
android:checked="true"/>
(the drawable "ic_none", is simple a 135x135 "transparent" image with nothing in it...)
Style (CheckBoxBackgroundView):
<style name="CheckBoxBackgroundView">
<item name="android:background">#drawable/background_day_week_picker_box_selector</item>
<item name="android:textColor">#color/text_color_day_week_picker_box_selector</item>
<item name="android:textSize">#dimen/text_spinner_text</item>
<item name="android:textStyle">bold</item>
</style>
Background Selector (background_day_week_picker_box_selector):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false"
android:drawable="#drawable/background_day_of_week_picker_unselected" />
<item android:state_checked="true"
android:drawable="#drawable/background_day_of_week_picker_selected" />
</selector>
Background selected (background_day_of_week_picker_selected):
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<!-- view background color -->
<solid
android:color="#color/red_color" >
</solid>
<!-- view border color and width -->
<stroke
android:width="3dp"
android:color="#color/transparent">
</stroke>
<!-- Here is the corner radius -->
<corners
android:radius="10dp" >
</corners>
</shape>
and finally the color selector (text_color_day_week_picker_box_selector):
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="false"
android:color="#color/red_color"></item>
<item android:state_checked="true"
android:color="#color/white"></item>
</selector>
I tried this in several devices... in some, it appears like it suppose to, in others the text disappears and it looks like this:
(http://i.imgur.com/Jy9FrPS.png)
probably is coincidence, but all the devices that worked are below 5 inches...
is there anything wrong with my code that I'm not seeing? anyone have any suggestions?
Thanks in advance
The problem is that the 135x135 button drawable is pushing the text out of the bounds of your CheckBox's width. Instead of using a drawable, you can just set android:button="#color/transparent".

defining xml file for button to change background AND textColor based on state

I use this for my own button to set the background for state pressed and unpressed:
<?xml version="1.0" encoding="utf-8"?>
<item android:drawable="#drawable/btn1_pressed" android:state_pressed="true"/>
<item android:drawable="#drawable/btn1_unpressed"/> <!-- default -->
But I also like the textColor to become white in state pressed.
I tried to just add textColor="#ffffff" to the item but I guess that's not the correct way, since it did not work.
What would be the best approach without having to code it in each java file that uses this button?
Thanks!
The best is to set Textcolor and Background resource separate.
android:background="#drawable/background"
android:textColor="#drawable/button_text_color"
so your Background: as you wrote it yourself
and Textcolor:
<?xml version="1.0" encoding="UTF-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#ffffffff" />
<item android:color="#ff000000" />
</selector>

change button text color when pressed

I have made my button transparent so I would like to have the button text color change when the button is pressed. Is it possible to do this using just xml files?
Yes, you can do it like that:
layout/main_layout.xml:
.....
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bonjour !"
android:textColor="#color/button_text_color"
/>
.....
color/button_text_color.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#c0c0c0" android:state_pressed="true"/>
<item android:color="#ffffff"/>
</selector>
See the section called State List in this bit of documentation...Drawable Resources.
You can define two different Button xml files one for the transparent 'default' state and another with the button as Red for your 'pressed' state. You then define a selector which switches the drawable resources in the different states.
EDIT: As per devunwired's comment the Color State List resource is probably more suitable for just changing colours rather than the drawable itself.
I like the solution proposed by Konstantin Burov in the other issue: Android customized button; changing text color
You can actually manage more states than just pressed and normal. But it should solve the problem.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"
android:color="#ffffff" />
<!-- Focused and pressed -->
<item android:state_focused="true"
android:state_pressed="true"
android:color="#000000" />
<!-- Unfocused and pressed -->
<item android:state_focused="false"
android:state_pressed="true"
android:color="#000000" />
<!-- Default color -->
<item android:color="#ffffff" />
</selector>
Then you can use that selector drawable in your button changing the text color attribute like below. Note that the selector in the example below is named "button_text_color"
android:textColor="#drawable/button_text_color"
Using the same drawable approach you can also solve the background color of the button. Just remember that in the selector instead of using the "android:color" attribute you need to use the "android:drawable" attribute like below.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Focused and not pressed -->
<item android:state_focused="true"
android:state_pressed="false"
android:drawable="#ffffff" />
<!-- Focused and pressed -->
<item android:state_focused="true"
android:state_pressed="true"
android:drawable="#000000" />
<!-- Unfocused and pressed -->
<item android:state_focused="false"
android:state_pressed="true"
android:drawable="#000000" />
<!-- Default color -->
<item android:drawable="#ffffff" />
</selector>
And then in the button itself do, note that this time the selector name is "button_background"
android:background="#drawable/button_background"
You have to do it in your code. Try this:
mBtn = ((Button) findViewById( R.id.button1 ));
mBtn.setOnClickListener( new OnClickListener() {
#Override
public void onClick(View v) {
mBtn.setTextColor( Color.RED );
}
});
Declare:
private Button mBtn;
You must set #drawable xml resource in textColor attributte
Here is example: Android customized button; changing text color
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_pressed="false"
android:color="#FFFFFF" />
<item
android:state_pressed="true"
android:color="#000000" />
</selector>

How to change the background color of the toggle button on Android

I tried to change the background color of the toggle button using XML file as white color, but the toggle button is totally damaged. It looks like all the button was covered with white.
There is no indication of ON or OFF on the toggle button when I have changed the color of the toggle button to white. Is there is another way to change the background which will not damage the indication of the toggle button?
<ToggleButton android:id="#+id/togglebutton"
android:layout_width="100px"
android:layout_height="46px"
android:background="#ffffff"
android:layout_above ="#+id/save"
android:textOn="DAY"
android:textOff="NIGHT" />
This is how my XML code look for the toggle button.
Yes, there is a way to change the background as you wish, but you have to use a selector like this as background:
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:state_focused="true"
android:state_pressed="false"
android:drawable="#drawable/some_image" />
<item
android:state_focused="true"
android:state_pressed="true"
android:drawable="#drawable/some_other_image" />
<item
android:state_focused="false"
android:state_pressed="false"
android:drawable="#drawable/some_image1" />
<item
android:state_focused="false"
android:state_pressed="true"
android:drawable="#drawable/other_image" />
</selector>
For #Drawable, etc. (you can use a color or make a gradient. Check this for more information about gradients.
Follow this way to make your ToogleButton have background color red when On and green when OFF
First, create tooglebutton_selector.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/togglebutton_on"
android:state_checked="true" />
<item android:drawable="#drawable/togglebutton_off"
android:state_checked="false"
/>
</selector>
Second, create togglebutton_on.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#ff0000" /> // red color
</shape>
Third, create togglebutton_off.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#00FF00" /> // green color
</shape>
Finally, in your ToggleButton
<ToggleButton
android:id="#+id/btnMon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/tooglebutton_selector" //set background of ToggleButton to tooglebutton_selector
/>
When you decompile your SystemUI.apk, you should go to the following file: SystemUI/res/values/colors.xml
Then change the following line:
#ff000000
#ffffffff
#80000000
#ffadc1d6
#ffffffff
#ffe6e6e6

How to change textColor of a button from XML in Android?

I am using a selector to change the background drawable of the button in different states (focused, pressed, normal). Is there any way to change the text color too? I want to provide various text colors for various button states, but I want to do it from the xml. Is this possible?
Yes it can be done. You just do the same way you do for the button drawable. Then assign it to android:textColor="#drawable/yourselector"
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#000000" /> <!-- pressed -->
<item android:state_focused="true"
android:color="#000000" /> <!-- focused -->
<item android:color="#FFFFFF" /> <!-- default -->
</selector>
Try combining the above with the android:drawable attribute.
If it's programmatically, you could use:
Button button = findViewById(R.id.yourbutton);
button.setTextColor(Color.yourcolor);
In xml it'll be the same thing.
Use android:color="#ff0000" in selector for focused and another color for default state.Then in xml of button android:textColor="#drawable/yourselector"
