Android own Activity start function

i've tried to start an activity with my own function, but it doesn't work (think its a logic fault ;) )

Please have a look at:

Intent adder = new Add().execute(this, Add.class, "Test:","Add the test");
        startActivity(adder);

This is the Activity which i want to start:

 public class Add extends Activity {

public Intent execute(Context context, Class<?> cls, String addText, String buttonText) {
    TextView addStr = (TextView) findViewById(R.id.addtext);
 开发者_JAVA百科   addStr.setText(addText);
    Button addBtn = (Button) findViewById(R.id.addbtn);
    addBtn.setText(buttonText);
    return new Intent(context, cls);
}

}

What's wrong?

You should take a look at this Android developer guide, which talks about Activity and Intent. I think you will see that they are used in a completely different way than you are trying to use them.
