<p>I have a class to create the dialog and coding to get the values from it. it works fine for one. and when i try to call dialog for the second time it passes following error message.</p>

<blockquote>
  <p>: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.</p>

<p>Can you please tell me how to remove the removeView()?</p>

<p>here is the code for the class;</p>

<pre><code>    package com.util;

  super(context);  
  setTitle(title);
  //:TODO Display msg only if not empty
  //setMessage(message);  

  input = new EditText(context);  
  setView(input);  

  setPositiveButton("ok", this);  
  setNegativeButton("cancel", this);  
 }

<p>and here is the code that i call the instance of the class;</p>

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



final PromptDialog dlgName = new PromptDialog(this, R.string.enterName, R.string.enter_comment) {  
             @Override  
             public boolean onOkClicked(String input) {  
              // do something 
              mName = input;
                  save();
                          //end do some thing
              return true; // true = close dialog  
             }  
        };      


    mTxtShiftName = (TextView) findViewById(R.id.shiftname);
            mTxtShiftName.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                dlgName.show();
            }   
        });
