文本视图中文本的默认颜色是什么？

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.

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

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

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

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

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

Actually the color TextView is:

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

or

#808080

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

textPrimaryColor = #000000

and

textColorPrimaryDark = #757575

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

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());

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 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();
}

The color of text inside a TextView is totally dependent on your theme. The easiest way to know it:

1. Add a TextView to any xml file
2. Select the TextView
3. Click on Split view
4. 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
