Trying to set custom font on TextView - nullpointer

I have no underlined code, but as soon as i start my app on emulator, i'm receiving these errors.

    FATAL EXCEPTION: main

And this is my SplashActivity:

public class SplashActivity extends AppCompatActivity {
    private TextView etSportisa;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
       /* ButterKnife.inject(this);
        mProgressBar.setIndeterminateDrawable(new foldingCirclesDrawable.Builder(this)
                .build());
        mProgressBar.setIndeterminateDrawable(new foldingCirclesDrawable.Builder(this)
                .colors(getResources().getIntArray(R.array.colors) //Array of 4 colors
                        .build()); */

        Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
        etSportisa.setTypeface(myTypeFace);
        etSportisa = (TextView) findViewById(R.id.tv_sportisa);



        final ProgressDialog pd = new ProgressDialog(SplashActivity.this);
        pd.setMessage("Učitavanje...");
        pd.show();

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                // Actions to do after 10 seconds
                pd.dismiss();

                Intent i = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(i);
            }
        }, 2000);
    }
}

Special font is added in assets\font folder. I also added an image for the loading screen but i think that the font is cousin those issues

Make the following changes to your code:

Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
etSportisa = (TextView) findViewById(R.id.tv_sportisa);
etSportisa.setTypeface(myTypeFace);

After initialization, you can do any operation with any layout.

The problem is here:

etSportisa is null

set it after you findViewByID

Typeface myTypeFace = Typeface.createFromAsset(getAssets(), "fonts/esp_ital.ttf");
        etSportisa = (TextView) findViewById(R.id.tv_sportisa);
        etSportisa.setTypeface(myTypeFace);
