Question

i have this Intent Code:

Intent arbeiten = new Intent(this, arbeiten.class);
startActivity(arbeiten);

but Eclipse tells me:

The constructor Intent(new AdapterView.OnItemClickListener(){}, Class<arbeiten>) is undefined

Other (working) Intents in the same Project, but other Class looks like

Intent toolb = new Intent(this, ToolBox.class);
toolb.putExtra("json", json.toString());
startActivity(toolb);

And they are working…

The “Arbeiten”-Class looks like this:

package XXX;
import android.app.Activity;
import android.os.Bundle;

public class arbeiten extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

Answer 1

It is because this refers to your OnItemClickListener. There are different ways of solving this. One way is to make a reference to the context of the activity like this:

Context mContext;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //your code

    mContext = this;
}

Then in your OnClickListener, change it to this:

Intent arbeiten = new Intent(mContext, arbeiten.class);
startActivity(arbeiten);
