에 표시해야 선택보다 다시 대화 상자를 엽니 다

public class sample extends Activity{ 

NumberPicker MyNumPicker1, MyNumPicker2, MyNumPicker3; 
TextView txtMyText; 
AlertDialog alertdialog; 

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

    txtMyText = (TextView) findViewById(R.id.txtMyText); 
    txtMyText.setText("5"); 

    txtMyText.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       View v1 = inflater.inflate(R.layout.numpicker, null); 
       MyNumPicker1 = (NumberPicker) v1.findViewById(R.id.MyNunPicker1); 
       MyNumPicker2 = (NumberPicker) v1.findViewById(R.id.MyNunPicker2); 
       MyNumPicker3 = (NumberPicker) v1.findViewById(R.id.MyNunPicker3); 

       MyNumPicker1.setMaxValue(20); 
       MyNumPicker1.setMinValue(1); 
       MyNumPicker1.setValue(Integer.parseInt(txtMyText.getText().toString())); 
       MyNumPicker1.setWrapSelectorWheel(true); 

       MyNumPicker2.setMaxValue(20); 
       MyNumPicker2.setMinValue(1); 
       MyNumPicker2.setValue(Integer.parseInt(txtMyText.getText().toString())); 
       MyNumPicker2.setWrapSelectorWheel(true); 

       MyNumPicker3.setMaxValue(20); 
       MyNumPicker3.setMinValue(1); 
       MyNumPicker3.setValue(Integer.parseInt(txtMyText.getText().toString())); 
       MyNumPicker3.setWrapSelectorWheel(true); 


       AlertDialog.Builder builder = new AlertDialog.Builder(sample.this); 

       builder.setView(v1); 
       builder.setTitle("Select Number"); 
       builder.setPositiveButton("Set", new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         int NumVal1 = MyNumPicker1.getValue(); 
         int NumVal2 = MyNumPicker2.getValue(); 
         int NumVal3 = MyNumPicker3.getValue(); 

         txtMyText.setText(""+ ((NumVal1 * 100) + (NumVal2 * 10) + NumVal3)); 
        } 
       }); 

       builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         alertdialog.dismiss(); 

        } 
       }); 

       alertdialog = builder.create(); 
       alertdialog.show(); 

      } 
     }); 
} 

}
