Mudei o Intent do AndroidMnifest pra ver se o erro tava na chamada do recurso ou na própria Activity do formulário e percebi que provavelmente o erro está na Activity do formulário, visto que ao pedir pro aplicativo rodar no emulador, ele já abre com o erro destacado acima e fecha.
Poderiam me ajudar a localizar onde está o erro?
Segue abaixo o código do meu FormularioActivity.java:
package br.com.alura.agenda;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class FormularioActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_formulario);
Button botaoSalvar = (Button) findViewById(R.id.formulario_nota);
botaoSalvar.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(FormularioActivity.this, "Salvo", Toast.LENGTH_SHORT).show();
}
});
}
}
Segue abaixo o código do meu activity_formulario.xml:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<EditText

android:layout_height="wrap_content"
android:hint="Nome"
android:id="@+id/formulario_nome"/>

android:layout_height="wrap_content"
android:numStars="5"
android:max="10"
android:layout_gravity="center"

/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Inserir"
android:id="@+id/formulario_salvar" />
</LinearLayout>
</ScrollView>
Segue abaixo o AndroidManifest com o Intent alterado pra classe Formulário Activity:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="br.com.alura.agenda">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".ListaAlunosActivity">
</activity>
<activity android:name=".FormularioActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Segue, ainda, para mais informações, as mensagens de erro retornadas ao tentar executar a aplicação:
