customlistadapter에서 activtygroup 호출하기

Question

탭 기능을 가진 안드로이드 앱을 만들고 있습니다.

모든 것이 잘 작동하지만 listadapter에서 activtygroup을 호출 할 수 없습니다.

import java.util.ArrayList; 

import android.app.Activity; 
import android.app.ActivityGroup; 
import android.content.Context; 
import android.content.Intent; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.Button; 
import android.widget.ImageView; 
import android.widget.TextView; 

import com.tv.socialgoal.R; 
import com.tv.socialgoal.imageloader.ImageLoader; 

public class AllyListAdapter extends BaseAdapter{ 
    Activity ctx; 
    ArrayList<Object> alist; 
    private ImageLoader imageLoader; 

    AllyBean allyBean; 
    private String photoPath; 

    public AllyListAdapter(Activity ctx, ArrayList<Object> alist) { 
     super(); 
     this.ctx = ctx; 
     this.alist = alist; 
     imageLoader=new ImageLoader(ctx); 
    } 

    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return alist.size(); 
    } 

    @Override 
    public Object getItem(int arg0) { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    public long getItemId(int arg0) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 

    @Override 
    public View getView(int position, View arg1, ViewGroup arg2) { 
     LayoutInflater linf=(LayoutInflater) ctx.getSystemService(ctx.LAYOUT_INFLATER_SERVICE); 
     View v=linf.inflate(R.layout.ally_list_row, null); 
     TextView tv=(TextView)v.findViewById(R.id.allyName); 
     ImageView profileImage=(ImageView)v.findViewById(R.id.ally_image); 
     Button inviteBtn=(Button)v.findViewById(R.id.invite_btn); 

     //SHOW DATA FROM LIST 
     allyBean=(AllyBean)alist.get(position); 
     tv.setText(allyBean.getName()); 
     photoPath=allyBean.getAvatar(); 

     profileImage.setTag(photoPath); 
     imageLoader.displayImage(photoPath, ctx, profileImage, false); 

     inviteBtn.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       Intent intent=new Intent(ctx,AddRemoveFriendScreen.class); 
       //intent.putExtra("friendId", allyBean.getUserId()); 
       ctx.startActivity(intent); 
      } 
     }); 
     return v; 
    } 

    /*public void replaceContentView(String id, Intent newIntent) { 
     View view =getLocalActivityManager().startActivity(id, 
       newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)) 
       .getDecorView(); 
     this.setContentView(view); 
    }*/ 
} 

가 지금은 AddRemoveFriends의 activtygroup 전화를해야 :

여기에 목록 어댑터 내 코드입니다.

방법 listadapter에서 activtygroup 전화하라고 제안하십시오 : 여기

는 activtygroup 코드입니다.

Answer 1

이와 같이하면 모든 것을 액세스 할 수 있습니다.

public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse 
    { 

     @Override 
     protected void onCreate(Bundle savedInstanceState) 
      { 
      ....... 
      } 

     class AllyListAdapter extends BaseAdapter 
     { 
       //Now you can call everything from ActivityGroup 
     } 
    } 

희망이 도움이 될 것입니다.

Answer 2

android developper reference에 따르면 Fragments를 사용할 수 있습니다.

ActivityGroup은 더 이상 사용되지 않습니다. 새 Fragment 및 FragmentManager API를 대신 사용하십시오. 이것들은 안드로이드 호환성 패키지를 통해 이전 플랫폼에서도 사용할 수 있습니다.

이 트릭을 시도 할 수 있습니다.

inviteBtn.setOnClickListener(new OnClickListener() { 

    public void onClick(View v) { 
     if(ctx instanceof ActivityGroup){ 
      Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class); 
      //intent.putExtra("friendId", allyBean.getUserId()); 
      ctx.getParent().startActivity(intent); 
     } 
     else{ 
      Intent intent = new Intent(ctx,AddRemoveFriendScreen.class); 
      //intent.putExtra("friendId", allyBean.getUserId()); 
      ctx.startActivity(intent); 
     } 
    } 
}); 

그래도 작동하지 않으면 AddRemoveFriendScreen 클래스에서 어댑터의 내부 클래스를 사용하십시오.
