Question

I have a library that requires to use the color of the TextView for the ActionBar title. Prior to AppCompat v7 r21 I could just findViewById(

Answer 1

No need for creating your own TextView, just loop through toolbar children to get the built-in title.

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

// loop through all toolbar children right after setting support 
// action bar because the text view has no id assigned

// also make sure that the activity has some title here
// because calling setText() with an empty string actually
// removes the text view from the toolbar

TextView toolbarTitle = null;
for (int i = 0; i < toolbar.getChildCount(); ++i) {
    View child = toolbar.getChildAt(i);

    // assuming that the title is the first instance of TextView
    // you can also check if the title string matches
    if (child instanceof TextView) {
        toolbarTitle = (TextView)child;
        break;
    }
}
