I have activity with Navigation Drawer, I want to set text to NavigationDrawer HeaderView. I have written below code, but it gets crashed.


Caused by: java.lang.NullPointerException: Attempt to invoke virtual
method ‘void android.widget.TextView.setText(int)’ on a null object

protected void onCreate(Bundle savedInstanceState) {

[...]

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this);

TextView name = findViewById(R.id.username);

name.setText(R.string.af_anasayfa_af_butonu);

}

 

Could you pls help to resolve this exception.

Thanks in advance
