Android自定义字体Lollipop

Question

I have two TextView which I want to put a custom font on.

In the OnCreate of my MainActivity, after the setContentView call, I wrote the following code:

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/BernerBasisschrift1.ttf");
TextView welcomeTextView = (TextView)findViewById(R.id.welcome_message);
TextView introTextView = (TextView)findViewById(R.id.introduction_message);

welcomeTextView.setTypeface(myTypeface);        
introTextView.setTypeface(myTypeface);

But for some reason, the font stays default.

The app runs on Galaxy S6 Edge device (Lollipop 5.0.2).

I read here that there's a problem with custom fonts on Lollipop, and in order to fix it I converted my font with the tool provided in the thread to ttx and vice versa, but even this didn't help.

Any ideas what can I do?

Edit: Tested on Jellybean (4.3), not working either.

Another edit: It works on a clean new project! Cant figure out the difference. Putting the MainActivity and its' XML for help:

public class MainActivity extends FragmentActivity {

private LoginFragment loginFragment;
private TextView welcomeTextView;
private TextView introTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    hideActionBar();
    setContentView(R.layout.activity_main);

    welcomeTextView = (TextView)findViewById(R.id.welcome_message);
    introTextView = (TextView)findViewById(R.id.introduction_message);

    Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/BernerBasisschrift1.ttf");
    welcomeTextView.setTypeface(myTypeface);
    introTextView.setTypeface(myTypeface);

    if (savedInstanceState == null) {
        // Add the fragment on initial activity setup
        loginFragment = new LoginFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, loginFragment, "facebookFragment").commit();

    }

}


@Override
public void onWindowFocusChanged(boolean hasFocus) {

    if(hasFocus){
        // get all views on screen
        ArrayList<View> views = new ArrayList<View>()
        {{
            add(findViewById(R.id.welcome_message));
            add(findViewById(R.id.introduction_message));
            add(findViewById(R.id.below_login));
            add(findViewById(R.id.above_login));
            add(findViewById(R.id.authButton));
            add(findViewById(R.id.logo));
        }};

        // set animations
        for(View view : views)
            YoYo.with(Techniques.Tada).duration(700).playOn(view);

    }
}

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public void hideActionBar(){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
        getActionBar().hide();
}

And the activity's XML:

Answer 1

Ok so I found out recently that the facebook login button caused the problem, since everything worked when it was commented out.

So basically to solve this problem use another method to show the button instead using support fragment manager; sdk docs has lots of examples.
