Checkbox's - Application Crashes при запуске

Question

Я следовал этому образцу http://examples.javacodegeeks.com/android/core/ui/checkbox-ui/android-checkbox-example/, чтобы добавить флажок в мой добавить, но каждый раз, когда добавляю addListenerOnChkWindows(); и addListenerOnButton();, приложение вылетает при запуске. Heres мой код:

public class MainActivity extends Activity { 

    private static final List<String> PERMISSIONS = Arrays.asList("publish_actions"); 
    private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization"; 
    private boolean pendingPublishReauthorization = false; 
    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerList; 
    private ActionBarDrawerToggle mDrawerToggle; 

    // nav drawer title 
    private CharSequence mDrawerTitle; 

    // used to store app title 
    private CharSequence mTitle; 

    // slide menu items 
    private String[] navMenuTitles; 
    private TypedArray navMenuIcons; 

    private ArrayList<NavDrawerItem> navDrawerItems; 
    private NavDrawerListAdapter adapter; 
    private Button shareButton; 
    private CheckBox linux, macos, windows; 

     private Button button;

     // load slide menu items 
     navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

     // adding nav drawer items to array

Answer 1

Стек трассировки будет быть полезным, чтобы ответить на ваш вопрос. Тем не менее, я готов поспорить, что проблема заключается в вашем xml-макете, который вы определили shareButton как Button, в то время как в вашем коде в addListenerOnChkWindows() вы добавили его в CheckBox. Вы, вероятно, хотели использовать R.id.tr вместо R.id.shareButton в этом методе?

Обновление: В addListenerOnChkWindows() изменить строку:

окна = (CheckBox) findViewById (R.id.shareButton);

к:

окна = (CheckBox) findViewById (R.id.tr);
