Problem with customized alert dialog

[Anjul]

On a button click say status, i want that a pop up window appears which lets a user set a status message and which in turn is displayed in the status message field.
I thought of using a customized alert dialog.
here is the xml file of my dialog layout:

I am getting the dialog. However onpositiveButtonClick

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/layout_root"
              android:orientation="horizontal"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
              android:padding="10dp"
              >
    <EditText android:id="@+id/text"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"
            
              />
                            
</LinearLayout>

in the java file, i am displaying the dialog as follws:

AlertDialog.Builder builder;
					    	Context mContext = MyProfileActivity.this;
					    	LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
					    	final View layout = inflater.inflate(R.layout.status_dialog,
					    	                               (ViewGroup) findViewById(R.id.layout_root));
					    	
					    	builder = new AlertDialog.Builder(mContext);
					    	builder.setView(layout);
					    	builder.setTitle("Add Status message").
					    		setCancelable(false).
					    		setPositiveButton("Update Status", new DialogInterface.OnClickListener() {
								
								@Override
								public void onClick(DialogInterface dialog, int which) {
									EditText text = (EditText) layout.findViewById(R.id.text); // compile time error
					    			TextView statusTxt = (TextView)findViewById(R.id.status_txt);
					    			statusTxt.setText(text.getText().toString());
					    			MyProfileActivity.this.dismissDialog(DIALOG_STATUS);
								}
							}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
								
								@Override
								public void onClick(DialogInterface dialog, int which) {
									dialog.dismiss();
									
								}
							});
					    	alertDialog = builder.create();

Now i am getting the dialog, but i am not able to retrieve the text entered the text field on positive(update) button click..
Please suggest me a way to retrieve my editText view in onclick() method.
