Я новичок в разработке для Android, и у меня возникли проблемы с Force Close на новых страницах активности Android.
Моя структура такова:
Главная страница -> Страница меню (работает нормально) -> Экран новой игры (принудительное закрытие)
Позвонить на мероприятие:
public void btnNewGame_Click(View view)
{
Intent i = new Intent(this, NewGameScreen.class);
startActivityForResult(i, ACTIVITY_CREATE);
}
Manifest
<activity android:name=".NewGameScreen"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
XML
<?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="fill_parent"
android:orientation="vertical" >
<ExpandableListView
android:id="@+id/eLVGameList"
android:layout_width="match_parent"
android:layout_gravity="center_vertical"
android:layout_weight=".75"
android:background="@null" android:layout_height="0dip">
</ExpandableListView>
</LinearLayout>
NewGameScreenActivity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.loadgame);
ExpandableListView epView = (ExpandableListView) findViewById(R.id.eLVGameList);
ExpandableListAdapter mAdapter = new GameListAdapter();
epView.setAdapter(mAdapter);
