Getting Java.lang.NullPointException while getting ActionBar Title ID for inflating custom color

Question

I am trying to get title Id of Action Bar so as to inflate color.

Trying same as undermentioned ..

   actionBar = getSupportActionBar();
        int titleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
        TextView yourTextView = (TextView) findViewById(titleId);
        actionBar.setTitle("Sign in or Create an account");
        yourTextView.setTextColor(getResources().getColor(R.color.taxi_blue));
        actionBar.setBackgroundDrawable(getResources().getDrawable(R.color.white));
        actionBar.setDisplayShowTitleEnabled(true);

This is working great in higher version but when I try same in lower version I am getting NullPointException

I am getting exception at ..

yourTextView.setTextColor(getResources().getColor(R.color.taxi_blue));

I have used back support library for same.

Really stuck on this.

Any hint on this is appreciated.

So what should I use .. Any hint on this or any suggestion for how to use same.? — AndroidHacker, Jan 31 '14 at 11:05
@AndroidHacker why don't you deifne styles for title and set the color — Raghunandan, Jan 31 '14 at 11:06
@Raghunandan ..Yeah I tried that but failed :(.. Will be obliged if I get hint from your side — AndroidHacker, Jan 31 '14 at 11:07
@AndroidHacker have the styles in respective res/values folder and it will work — Raghunandan, Jan 31 '14 at 11:09
are you using ABS or ActionBarCompact for backwards compatibility? — Blackbelt, Jan 31 '14 at 11:10
Actually when I tried using styles then stuff worked for lower versions but not for higher version. As I say that my background color was inflating in lower version but not on higher version. Thanks — AndroidHacker, Jan 31 '14 at 11:10
@AndroidHacker you probably din't have styles define for higher vesion in the respective res/values folder — Raghunandan, Jan 31 '14 at 11:11
@Raghunandan Might be you are right. Can you please guide me on this.. — AndroidHacker, Jan 31 '14 at 11:12
@AndroidHacker check this http://stackoverflow.com/questions/21300920/change-action-bar-overflow-icon/21302679#21302679 has a example for higher version — Raghunandan, Jan 31 '14 at 11:13

action_bar_title is not found in "lower versions".

Since you are only changing the textcolor. You could probably be okay using:

ActionBar actionBar = getSupportActionBar();
actionBar.setTitle(Html.fromHtml("<font color='#ff0000'>Sign in or Create an account</font>"));

Of course, replace #ff0000 with your color defined by R.color.taxi_blue
