How to use attributes to change text color from activity

Question

This is my code

 TextView text_language_name4 = (TextView)view.findViewById(R.id.text);
                     if (text_language_name4 != null) {
                         int text_color4 = selected
                                 ? getResources().getColor(R.color.readcolor)
                                         : getResources().getColor(R.color.readcolor);                
                                 text_language_name4.setTextColor(text_color4);
                         text_language_name4.setDuplicateParentStateEnabled(true);

                 }

When i am using R.attr.mytheme my app forces close

That answer is different than asked. Color needs to be changed by using attribute rather than color resource — Jimit Patel, Mar 03 '20 at 09:50

For the theme color try like this:

TypedValue tV = new TypedValue();
Theme theme = context.getTheme();
boolean success = theme.resolveAttribute(R.attr.theme_color, tV, true);
int colorFromTheme;
if(success)
    colorFromTheme = tV.data;
else
    // value not found....

Now set,

textView.setTextColor(colorFromTheme);

You can use something like this if i understood your problem right:

textView.setTextColor(Color.parseColor("#ffffff"));

While "#ffffff" is the hex value of the color.

Assuming you have:

<color name="green">#0000ff00</color>

And here is code:

int greenColor = getResources().getColor(R.color.green);
 String strGreenColor = "#"+Integer.toHexString(greenColor);

mTextView.setTextColor(Color.parseColor(""+greenColor));
