Re: [androidbrasil-dev] Problema ao chamar tela a partir de um botão

E ai galera blz?

Sou inciante e algumas coisas consigo fazer e outras q são faceis eu empaco =/

Fiz um projeto pra fazer funcionar um mapa nos meus teste e consegui.

Fiz outro projeto pra criar telinha com botoes e chamar outra tela e tb consegui.

Ai decidi fazer o mapa funcionar no projeto com as telinhas para ele aparecer quando clicar no botao Mapa.

Ai q ta a caca, quando clico no botao Mapa da pau e o aplicativo para.

Problema: btnTelaMapa ... os outros botoes funcionam normalmente.

Codigos:

Main

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

public void btnExibirNestaTela(View view) {

// Recupera o elemento da tela e o seu texto.

EditText primeiroCampo = (EditText) findViewById(R.id.editText1);

String mensagem = primeiroCampo.getText().toString();

 

// Exibe a mensagem.

Toast.makeText(this, mensagem, Toast.LENGTH_LONG).show();

}

public void btnExibirNovaTela(View view) {

// Recupera o elemento da tela e o seu texto.

EditText segundoCampo = (EditText) findViewById(R.id.editText2);

String mensagem = segundoCampo.getText().toString();

 

// Cria o intent com a mensagem a ser passada para a onva tela.

Intent intent = new Intent(this, SecondActivity.class);

intent.putExtra("mensagem", mensagem);

 

// Inicia a nova tela.

startActivity(intent);

}

public void btnTelaMapa (View view) {

Intent i = new Intent(this, MapActivity.class);

        startActivity(i);

}

}
