Salve,
codice:Vorrei aprire una nuova finestra(classe Form) attraverso un bottone public class MainActivity extends Activity { protected void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.activity_main); final Button button = (Button) findViewById(R.id.form_button); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // your handler code here setContentView(R.layout.form); final EditText edit_name = (EditText)findViewById(R.id.edit_name); final EditText edit_lastname = (EditText)findViewById(R.id.edit_lastname); Bundle bundle = new Bundle(); bundle.putString("name", edit_name.getText().toString()); bundle.putString("lastname", edit_lastname.getText().toString()); Intent form_intent = new Intent(getApplicationContext(), Form.class); form_intent.putExtras(bundle); startActivity(form_intent); } }); } }in modo tale da settare il nome inserito, ma dopo la pressione del bottone crasha.codice:public class Form extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.form); final TextView text_name = (TextView) findViewById(R.id.view_name); final TextView text_lastname = (TextView) findViewById(R.id.view_lastname); Bundle bundle = this.getIntent().getExtras(); text_name.setText(bundle.getString("name")); text_lastname.setText(bundle.getString("lastname")); } }
