OnOptionsMenu가 앱을 충돌하게합니다.

Question

특정 활동에 자동으로 생성 된 OnCreateOptionsMenu은 기기의 옵션 버튼을 누르면 충돌합니다. 동일한 작업이 다른 작업에 액세스하는 동안 앱을 중단시키지 않습니다. 같은 앱.

logcat의 불만 중 하나는 NPE이며이 오류의 원인을 알 수 없습니다. 모든 XML 파일이 정확합니다.

자바 코드 :

 @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     getWindow().setFormat(PixelFormat.TRANSPARENT);   
     getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
           WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     setContentView(R.layout.add_new_location_activity); 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.addnewloaction_optionsmenu, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    }

Answer 1

causes the app to crash when I press the options button in the device 

문제는 당신이 ActionBarActivity에 Window.FEATURE_NO_TITLE을 설정 한 이후의 ActionBar이 Activity 생성되지 않는다는 점이다. 하지만 너는 노력하고있어 inflate option menus.

대신 ActionBarActivity

public class AddNewLocationActivity extends ActionBarActivity { 

의 Activity을 확장 할 AddNewLocationActivity을 변경 : ActionBar 이후

는 getMenuInflater를 호출하려고 할 때의 ActionBar는

FIX 널이 활동을 위해 만들어지지 않습니다

public class AddNewLocationActivity extends Activity { 

장치 옵션 키를 사용하여 Menus에 계속 액세스 할 수 있습니다.
