Please specify what API version are you using when you are talking about new one. — DonPaulie, May 11 '18 at 11:36
You can try this name.setTextColor(ContextCompat.getColor(this, R.color.white) — Arshad, May 11 '18 at 11:39
Try with other colors like RED, BLUE, BLACK. You are trying White text on White background. — Abhishek, May 11 '18 at 11:41
provide your full code with xml and java then find any mistake. — , May 11 '18 at 11:41

textView.setTextColor(view.getResources().getColor(R.color.red_1));

This should work for most Api versions

getResources().getColor() is deprecated. Use this

TextView name = (TextView) findViewById(R.id.textview_name_id);
name.setTextColor(ContextCompat.getColor(context, R.color.black));

looks like you are confused with the `getApplicationContext()` or `getContext()`. Refer to this link for more explanation https://stackoverflow.com/questions/10641144/difference-between-getcontext-getapplicationcontext-getbasecontext-and – Lokesh Pandey May 11 '18 at 12:00
cannot resolve symbol context – May 11 '18 at 12:00
you need to use `getApplicationContext()`. by the way I have mentioned one link for you in my comment. I recommend you to go through that – Lokesh Pandey May 11 '18 at 12:02

I think you are missing TextView declaration and initialization in your activity.
Declare it as a variable of your activity, and initialize it after calling setContentView().

public class MainActivity extends Activity {

    private TextView mNameTextView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_launch);
        mNameTextView = (TextView)findViewById(R.id.name);
        // remaining codes
       mNameTextView.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.black));
  }
}

Try this method it's work fine on all Api levels.

public int _getColor(int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 23) {
        return ContextCompat.getColor(this, id);
    } else {
        return getResources().getColor(id);
    }
}
