I set the color to red , and after that I want to set the color again back to default, but I do not know what is default color, does anyone knows ?
You can save old color and then use it to restore the original value. Here is an example:
ColorStateList oldColors = textView.getTextColors(); //save original colors
textView.setTextColor(Color.RED);
....
textView.setTextColor(oldColors);//restore original colors
But in general default TextView
text color is determined from current Theme applied to your Activity
.
Actually the color TextView is:
android:textColor="@android:color/tab_indicator_text"
or
#808080

There are some default colors defined in android.R.color
int c = getResources().getColor(android.R.color.primary_text_dark);
int c = ...
instead of Color c = ...

Moralez getResources().getColor(int id)
is now deprecated (see link). You can either use getResources().getColor (int id, Resources.Theme theme)
or ContextCompat.getColor(contex, android.R.color.primary_text_dark)

Lager Get these values from attributes:
int[] attrs = new int[] { android.R.attr.textColorSecondary };
TypedArray a = getTheme().obtainStyledAttributes(R.style.AppTheme, attrs);
DEFAULT_TEXT_COLOR = a.getColor(0, Color.RED);
a.recycle();
There are defaults in the theme that Android uses if you don't specifiy a text color. It may be different colors in various Android UIs (e.g. HTC Sense, Samsung TouchWiz, etc). Android has a _dark
and _light
theme, so the defaults are different for these (but nearly black in both of them in vanilla android). It is however good practice to define your primary text color yourself for to provide a consistent style throughout the devices.
In code:
getResources().getColor(android.R.color.primary_text_dark);
getResources().getColor(android.R.color.primary_text_light);
In xml:
android:color="@android:color/primary_text_dark"
android:color="@android:color/primary_text_light"
As reference in vanilla Android the dark theme text color is #060001
and the in the light theme it's #060003
since API v1. See the android style class here
I know it is old but according to my own theme editor with default light theme, default
textPrimaryColor = #000000
and
textColorPrimaryDark = #757575
I used a color picker on the textview and got this #757575
It may not be possible in all situations, but why not simply use the value of a different random TextView that exists in the same Activity and that carries the colour you are looking for?
txtOk.setTextColor(txtSomeOtherText.getCurrentTextColor());
The color of text inside a TextView
is totally dependent on your theme.
The easiest way to know it:
- Add a
TextView
to any xml file - Select the
TextView
- Click on
Split
view - Open the
Attributes
tab and scroll to the color section.
As you can see, according to my theme it is: @android:color/secondary_text_material_light
There are some default colours which get defined in the Themes of app. Below is the code snippet which you can use to get the current default color programmatically.
protected int getDefaultTextColor(){
TextView textView = new TextView(getContext());
return textView.getCurrentTextColor();
}
I believe the default color integer value is 16711935 (0x00FF00FF).
hey you can try this
ColorStateList colorStateList = textView.getTextColors();
String hexColor = String.format("#%06X", (0xFFFFFF & colorStateList.getDefaultColor()));
I found that android:textColor="@android:color/secondary_text_dark"
provides a closer result to the default TextView color than android:textColor="@android:color/tab_indicator_text"
.
I suppose you have to switch between secondary_text_dark/light depending on the Theme you are using
You could use TextView.setTag/getTag to store original color before making changes. I would suggest to create an unique id resource in ids.xml to differentiate other tags if you have.
before setting to other colors:
if (textView.getTag(R.id.txt_default_color) == null) {
textView.setTag(R.id.txt_default_color, textView.currentTextColor)
}
Changing back:
textView.getTag(R.id.txt_default_color) as? Int then {
textView.setTextColor(this)
}
There is no default color. It means that every device can have own.
