Я работаю над своим первым Android приложением. Я только пришел, чтобы обнаружить фрагменты, и мне нужно, чтобы они создали ViewPager для создания хороших переходов между моими действиями, но я боюсь, что уже слишком поздно это реализовывать.
Я должен поместить весь свой код (MainActivity ) в моем главном фрагменте? Или просто некоторые кусочки, которые я не знаю, что я должен держать в своем MainActivity
Вот мой код
public class MainActivity extends FragmentActivity {
ObjectAnimator anim;
ObjectAnimator anim2;
private int display, result, detect = 0;
private NfcAdapter nfcAdapter;
private ImageButton nfcButton;
private PendingIntent pendingIntent;
private ImageButton qrButton;
private TextView text;
private SlidrInterface slidr;
private ImageButton webButton;
float x1, x2, y1, y2;
String link = null;
public final int CUSTOMIZED_REQUEST_CODE = 0x0000ffff;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
slidr = Slidr.attach(this);
setDetect(1);
setContentView((int) R.layout.activity_main);
this.text = (TextView) findViewById(R.id.text);
this.nfcAdapter = NfcAdapter.getDefaultAdapter(this);
this.nfcButton = (ImageButton) findViewById(R.id.nfc_button);
this.anim = ObjectAnimator.ofFloat(this.nfcButton, "scaleX", new float[]{0.9f});
this.anim2 = ObjectAnimator.ofFloat(this.nfcButton, "scaleY", new float[]{0.9f});
IntentIntegrator integrator = new IntentIntegrator(this);
this.nfcButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setDisplay(1);
manageBlinkEffect();
}
});
this.pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) { // RESULTAT DU SCAN QR CODE
