私は簡単なAndroidアプリケーションを開発していて、ホーム画面を完成させました。これで、画面の向きが2回以上変わると、エラーがスローされ、アプリケーションが突然クラッシュします。
これが私のJavaクラスです:
public class PasswordActivity extends Activity implements OnClickListener {
Button login;
Button forgot;
Button register;
private static final String PREFERENCES = "prefs";
private static final String PREFERENCES_NAME = "pref_name";
SharedPreferences settings;
private Cursor c;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
login=(Button)findViewById(R.id.login_login);
login.setOnClickListener(this);
register=(Button)findViewById(R.id.login_register);
register.setOnClickListener(this);
}
public void onClick(View v) {
}
}
そしてこれは私のXmlコードです:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
