Onitem长按不工作列表视图

Question

我有一个活动，实现onitemLongclicllstener列表视图。我使用parse.com作为我的后端，用于将数据检索到listvview中。一切正常，但onitemlongclicllstener不工作列表视图。什么也没有发生，当列表项被点击长

我的主要活动

public class InterActivity extends Activity implements OnItemLongClickListener 
{ 


ListView listview; 
List<ParseObject> ob; 
ProgressDialog mProgressDialog; 
FinalAdapter adapter; 
List<CodeList> codelist = null; 
SharedPreference shrdPreference; 



@Override 
public void onCreate(Bundle savedInstanceState) 
{ 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.inter_layout); 
    shrdPreference = new SharedPreference(); 
    //Execute RemoteDataTask AsyncTask 
    new RemoteDataTask().execute(); 
} 

private class RemoteDataTask extends AsyncTask<Void, Void, Void> { 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     // Create a progressdialog 
     mProgressDialog = new ProgressDialog(InterActivity.this); 
     // Set progressdialog title 
     mProgressDialog.setTitle("Loading"); 
     // Set progressdialog message 
     mProgressDialog.setMessage("Please wait loading ..."); 
     mProgressDialog.setIndeterminate(false); 
     mProgressDialog.setCancelable(false); 
     // Show progressdialog 
     mProgressDialog.show(); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     // Create the array 
     codelist = new ArrayList<CodeList>(); 
     try { 
      // Locate the class table named "Country" in Parse.com 
      ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(
       "InterActivity"); 
      // Locate the column named "ranknum" in Parse.com and order list 
      // by ascending 
      query.orderByAscending("_created_at"); 
      ob = query.find(); 
      for (ParseObject inter : ob) { 


       ParseFile video = (ParseFile) inter.get("demovideo"); 

     //  ParseFile downloadfile = (ParseFile) inter.get("download"); 

       CodeList map = new CodeList(); 
       map.setListHeading((String) inter.get("listheading")); 
       map.setSingleItemHeading((String) inter.get("heading")); 

       map.setDownloadCode((String) inter.get("download")); 


       map.setDailogdemovideo(video.getUrl()); 
    //   map.setDownloadCode(downloadfile.getUrl()); 

       codelist.add(map); 
      } 
     } catch (ParseException e) { 
      Log.e("Error", e.getMessage()); 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     // Locate the listview in listview_main.xml 
     listview = (ListView) findViewById(R.id.inter_layoutListView); 
     // Pass the results into ListViewAdapter.java 
     adapter = new FinalAdapter(InterActivity.this, 
             codelist); 
     // Binds the Adapter to the ListView 
     listview.setAdapter(adapter); 

     listview.setOnItemLongClickListener(InterActivity.this); 
     // Close the progressdialog 
     mProgressDialog.dismiss(); 
    } 
} 

@Override 
public boolean onItemLongClick(AdapterView<?> arg0, View view, int position, long arg3) 
{ 
    ImageView fvrtebutton = (ImageView) view.findViewById(R.id.favbtn); 


    String tag = fvrtebutton.getTag().toString(); 
    if (tag.equalsIgnoreCase("no")) { 
     shrdPreference.addFavorite(InterActivity.this, codelist.get(position)); 
     Toast.makeText(InterActivity.this, getString(R.string.fav_added), 
         Toast.LENGTH_SHORT).show(); 

     fvrtebutton.setTag("yes"); 
     fvrtebutton.setImageResource(R.drawable.favorite); 
    } else { 
     shrdPreference.removeFavorite(InterActivity.this, codelist.get(position)); 
     fvrtebutton.setTag("no"); 
     fvrtebutton.setImageResource(R.drawable.unfavorite); 
     Toast.makeText(InterActivity.this, 
         getString(R.string.fav_removed), 
         Toast.LENGTH_SHORT).show(); 
    } 
    return false; 
} 

@Override 
protected void onResume() 
{ 

    super.onResume(); 
} 



@Override 
public void onBackPressed() { 
    super.onBackPressed(); 
    overridePendingTransition(R.anim.left_to_right, R.anim.right_to_left); 

} 

最终adapter.java

public class FinalAdapter extends BaseAdapter 
{ 
Context context; 
LayoutInflater inflater; 
ImageLoader imgLoader; 
private List<CodeList> codeList = null; 
private ArrayList<CodeList> arraylist; 
SharedPreference shrdprfrnce; 

public FinalAdapter(Context context, 
        List<CodeList> codeList) { 
    this.context = context; 
    this.codeList = codeList; 
    inflater = LayoutInflater.from(context); 
    this.arraylist = new ArrayList<CodeList>(); 
    this.arraylist.addAll(codeList); 
    shrdprfrnce = new SharedPreference(); 
    imageLoader = new ImageLoader(context); 

} 

public class ViewHolder{ 
    TextView listHeading; 
    TextView listHash; 
    ImageView alphabetList; 
    ImageView favariteImage; 
} 


@Override 
public int getCount() 
{ 
    return codeList.size(); 
} 

@Override 
public Object getItem(int position) 
{ 
    return codeList.get(position); 
} 

@Override 
public long getItemId(int position) 
{ 
    return position; 
} 

@Override 
public View getView(final int position, View view, ViewGroup parent) 
{ 
    final ViewHolder holder; 
    if(view == null){ 
     holder = new ViewHolder(); 
     view = inflater.inflate(R.layout.beg_list_item,null); 
     holder.listHeading = (TextView) view.findViewById(R.id.beg_list_itemTextView); 

     //holder.listHash = (TextView) view.findViewById(R.id.listview_hashtags); 
     holder.alphabetList = (ImageView) view.findViewById(R.id.beg_list_itemImageView); 

     holder.favariteImage = (ImageView) view.findViewById(R.id.favbtn); 

     view.setTag(holder); 

    }else{ 
     holder = (ViewHolder) view.getTag(); 
    } 
    CodeList codes = (CodeList) getItem(position); 
    holder.listHeading.setText(codeList.get(position).getListHeading()); 
    imageLoader.DisplayImage(codeList.get(position).getAlphabetimg(), 
          holder.alphabetList); 


    if (checkFavoriteItem(codes)) { 
     holder.favariteImage.setImageResource(R.drawable.favorite); 
     holder.favariteImage.setTag("yes"); 
    } else { 
     holder.favariteImage.setImageResource(R.drawable.unfavorite); 
     holder.favariteImage.setTag("no"); 
    }      

    view.setOnClickListener(new OnClickListener(){ 

      @Override 
      public void onClick(View arg0){ 
       Intent intent = new Intent(context, SingleItemView.class); 

       //intent.putExtra("listheading", 
       //  (codeList.get(position).getListHeading())); 
       //intent.putExtra("alphabetimg", 
       //    (codeList.get(position).getAlphabetimg())); 

       intent.putExtra("demovideo", 
           (codeList.get(position).getDailogdemovideo())); 

       intent.putExtra("download", 
           (codeList.get(position).getDownloadCode())); 



       // Start SingleItemView Class 
       context.startActivity(intent); 

      } 
     });    

    return view; 
} 

public boolean checkFavoriteItem(CodeList checkCodes) { 
    boolean check = false; 
    List<CodeList> favorites = shrdprfrnce.getFavorites(context); 
    if (favorites != null) { 
     for (CodeList codes : favorites) { 
      if (codes.equals(checkCodes)) { 
       check = true; 
       break; 
      } 
     } 
    } 
    return check; 
} 


public void add(CodeList codes) { 
    (
    codeList.add(codes); 
    notifyDataSetChanged(); 
} 


public void remove(CodeList codes) { 

    codeList.remove(codes); 
    notifyDataSetChanged(); 
} 

}

Answer 1

plz remove 
view.setOnClickListener(new OnClickListener(){ 

     @Override 
     public void onClick(View arg0){ 
      Intent intent = new Intent(context, SingleItemView.class); 

      //intent.putExtra("listheading", 
      //  (codeList.get(position).getListHeading())); 
      //intent.putExtra("alphabetimg", 
      //    (codeList.get(position).getAlphabetimg())); 

      intent.putExtra("demovideo", 
          (codeList.get(position).getDailogdemovideo())); 

      intent.putExtra("download", 
          (codeList.get(position).getDownloadCode())); 



      // Start SingleItemView Class 
      context.startActivity(intent); 

     } 
    }); 

bcoz它得到充分视图点击那ŸUR OnLongClick还没有成型

Answer 2

与回报true尝试;

@Override 
public boolean onItemLongClick(AdapterView <?> arg0, View arg1, 
int pos, long id) { 

Log.v("long clicked", "pos: " + pos); 

return true; 
}
