What is default color for text in textview?

问题:

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 ?

回答1:

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.

回答2:

Actually the color TextView is:

android:textColor="@android:color/tab_indicator_text"

or

#808080

回答3:

There are some default colors defined in android.R.color

int c = getResources().getColor(android.R.color.primary_text_dark);

回答4:

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

回答6:

I believe the default color integer value is 16711935 (0x00FF00FF).

回答7:

I know it is old but according to my own theme editor with default light theme, default

textPrimaryColor = #000000

and

textColorPrimaryDark = #757575

回答8:

There is no default color. It means that every device can have own.
