안드로이드는 SlidingPaneLayout을 구현할 수없고, setContentView에서 실패합니다.

Question

나는이 질문을 이미했으나 아무도 대답하지 않았으므로 다시 묻습니다. android.support.v4.widget에서 SlidingPaneLayout을 구현하려고합니다. 가능한 대부분의 베어 본 코드를 구현하려고합니다. 무엇이든로드 할 수있는 유일한 방법은 내가 setContentView()을 주석으로 처리하는 것입니다. 코드 은이 더 간단 할 수 없으며 오류없이 실행되지 않습니다. 어떤 도움이라도 대단히 감사 할 것입니다.

MainActivity.java :

import android.app.Activity; 
import android.os.Bundle; 
import android.support.v4.widget.SlidingPaneLayout; 


public class MainActivity extends Activity { 

    SlidingPaneLayout paneLayout; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.root_layout); 

     /* 
     paneLayout = (SlidingPaneLayout) findViewById(R.id.root_layout); 
     paneLayout.setPanelSlideListener(new SlidingPaneLayout.SimplePanelSlideListener() { 
      @Override 
      public void onPanelSlide(View panel, float slideOffset) { 
       super.onPanelSlide(panel, slideOffset); 
      } 

      @Override 
      public void onPanelOpened(View panel) { 
       super.onPanelOpened(panel); 
      } 

      @Override 
      public void onPanelClosed(View panel) { 
       super.onPanelClosed(panel); 
      } 
     }); 
     */ 
    } 
}

public class ContentPane extends Fragment { 

    @Override

     View v = inflater.inflate(R.layout.content_pane, container, false); 
     return v;

Answer 1

, 당신은 FragmentActivity을 확장 할 필요가 - 그것은 당신에게 ClassCastException을주고 그것을가 android.app.Fragment (Activity로가의 지원 버전에 대해 알고하지 않습니다 예상대로 파편).
