J'ai une méthode IllegalStateException dans onCreate() lorsque j'appelle setContentView().Exception d'état non valide sur setContentView
L'exception se produit sur certains périphériques spécifiques. Surtout, sur les appareils Android version 4.4. Fonctionne bien sur d'autres appareils.
onCreate():
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager)findViewById(R.id.viewpager);
tabLayout = (TabLayout)findViewById(R.id.sliding_tabs);
CategoryAdapter categoryAdapter = new CategoryAdapter(this, getSupportFragmentManager());
}
Mise en page:
