Problema Intent

[Corax]

Ciao a tutti questo è il mio primo post in questa community. Speriamo di iniziare bene Ho un problema con il corso online di google (google course lab). Ho creato un programma che dovrebbe passare da un'activity all'altra modificando il contenuto della seconda (un HelloWorld avanzato più o meno). Purtruppo inserito il nome nel campo testo e premuto il tasto ok non accade nulla. Vi posto il codice e il manifest:

public class Click exten<span class="forTooltip">ds</span> android.app.Activity implements android.view.View.OnClickListener{<br /> <br /> @Override<br /> public void onClick(View v) {<br /> // TODO Auto-generated method stub<br /> String TypedText = (String)MyText.getText().toString();<br /> Intent MyInt = new Intent(this, HelloWorld.class);<br /> MyInt.putExtra("user", TypedText);<br /> this.startActivity(MyInt); <br /> Bundle Retrive = this.getIntent().getExtras();<br /> Retrive.getString("user");<br /> setContentView(R.id.Text);<br /> TextView TextV = (TextView)findViewById(R.id.Text);<br /> TextV.setText("user");<br /> <br /> <br /> <br /> }<br /> android.widget.EditText MyText;<br /> <br /> public void OnCreate (Bundle savedInstanceState){<br /> super.onCreate(savedInstanceState);<br /> this.setContentView(R.layout.name_getter);<br /> MyText = (EditText)this.findViewById(R.id.editText1);<br /> this.findViewById(R.id.button1);<br /> android.widget.Button RefBut = (Button)this.findViewById(R.id.button1);<br /> RefBut.setOnClickListener(this);<br /> <br /> }
