Change Color of Action Bar Title Android

I am writing an android app in which I am trying to change the color of the title of Action Bar by clicking on Button. As soon as, I click the button , the title gets hidden though I am passing the color code of YELLOW. Here is my Code of MainActitvity.java

Button B;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    B = (Button) findViewById(R.id.button1);
    B.setOnClickListener(this);
}


public void onClick(View v) {
    android.app.ActionBar actionBar = getActionBar();
    Internal.setActionBarTitleColor(actionBar, 256);
}

Internal.java

  public static void setActionBarTitleColor(android.app.ActionBar actionBar, int titleColor) {
    if(actionBar == null)
        return;

    try {
        Field actionViewField = actionBar.getClass().getDeclaredField("mActionView");
        actionViewField.setAccessible(true);
        Object actionView = actionViewField.get(actionBar);
        if(actionView == null)
            return;

        Field titleTextField = actionView.getClass().getDeclaredField("mTitleView");
        titleTextField.setAccessible(true);
        TextView titleText = (TextView)titleTextField.get(actionView);

        if(titleText != null)
            titleText.setTextColor(titleColor);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
actionBar.setBackgroundDrawable(new ColorDrawable(0xff00DDED));
actionBar.setDisplayShowTitleEnabled(false);  // required to force redraw
actionBar.setDisplayShowTitleEnabled(true);
    int titleId=Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
    TextView yourTextView = (TextView)findViewById(titleId); 
    yourTextView.setTextColor(getResources().getColor(R.color.white));

The ActionBar title ID is hidden, or in other words, it's internal and accessing it can't be done typically. You can reference it using Resources.getIdentifier.

Follow the step below:

1. Grab the ID for the action_bar_title

int titleId = getResources().getIdentifier("action_bar_title", "id", "android");

2. Now you can use the ID with a TextView

TextView abTitle = (TextView) findViewById(titleId);
abTitle.setTextColor(colorId);

That's all.
