Answer 1

, 당신이 때 하나의 대화 상자를 표시하려면이 부분에서 생각 소유자의 항목이 클릭됩니다. 이처럼

holder.month.setOnClickListener(new OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     final AlertDialog alertDialog = new AlertDialog.Builder(getApplicationContext()).create(); 
     alertDialog.setIcon(/*Provide any drawable*/); 
     alertDialog.setTitle("Alert Dialog"); 
     alertDialog.setMessage("Alert Dialog in OnClick"); 
     alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, 
      "Ok", 
      new OnClickListener() { 

       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        // TODO Auto-generated method stub 
        alertDialog.dismiss(); 
       } 
      }); 

     alertDialog.show(); 
    } 
});

사용 :이 방법을 시도 할 수 있습니다

public class MainActivity extends Activity { 

      class DataAdapter extends BaseAdapter { 


    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder holder = null; 

holder = new ViewHolder(); 

     //Onclick for your tagetyear TextView 
     holder.year = (TextView) convertView.findViewById(R.id.targetyear); 

     holder.year.setOnClickListener(new OnClickListener() { 

     @SuppressWarnings("unused") 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
    } 
    }); 
    } 
    } 
}
