Question

How can i make an intent on the same Activity?

I have a Activity Lektion which has forward and backwards buttons, and when i hit on the forward button i want to start the same Activity just with other parameters.
For that i also send a bundle with the Intent.

But the Activity isnt going to be created again as it seems…

public class Lektion extends Activity {
    private int rowCount = 0;
    private ArrayList<LektionPage> lektionPages = new ArrayList<LektionPage>();
    private int lektionPage = 0;
    private Bundle bundle;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.lektion);

        bundle = this.getIntent().getExtras();
        String lektionNummer = bundle.getString("LektionNummer");
        setTitle("Lektion "+lektionNummer);     

        try{
            lektionPage = bundle.getInt("LektionPage");
        } catch(Exception e){}

        forwardImageButton.setOnTouchListener(new OnTouchListener(){
            public boolean onTouch(View view, MotionEvent me) {
                if(lektionPage == rowCount){
                    return false;
                }
                Log.i("ontouch", ""+lektionPage);
                Intent intent = new Intent(Lektion.this, Lektion.class);
                bundle.putInt("LektionPage", lektionPage++);
                intent.putExtras(bundle);
                return true;
            }

        });
    }

You are only creating the intent without ever firing it.

You need to

startActivity(intent);

for the Intent to actually be executed.

But id say you should only change the content of the activities view etc instead of creating the activity over and over again
