EditText that looks like TextView inside a ListView

I am developing an application where the user can edit the data in the ListView. I want to have an EditText inside that ListView, this edittext should behave like TextView but when the user clicks it it should look like EditText, How can i achieve this functionality?

Actually the EditText inside the ListView looks ugly & i want that the EditText should look like a TextView bydefault but when the user try to Edit the data then it should look like the EditText.

I hope that my question is clear if not please ask.

The below files I used in my app.

main.xml in layout folder

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"    
    android:orientation="vertical" >
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <EditText android:layout_width="fill_parent"
        android:padding="5dip"
        android:layout_height="wrap_content"
        android:textColor="#00f"
        android:textSize="20dip"
        android:background="@drawable/bg" />    
    <EditText android:layout_width="fill_parent"
        android:padding="5dip"
        android:layout_height="wrap_content"
        android:textColor="#00f"
        android:textSize="20dip"
        android:background="@drawable/bg" />
</LinearLayout>

myshape.xml in drawable folder

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">   
    <solid   android:color="#fff"/> 
    <corners android:radius="2dip" />   
    <stroke android:width="2dip"
        android:color="#ff4500" />
</shape>

bg.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >    
    <item android:state_enabled="true"        
        android:state_focused="true"                        
        android:drawable="@drawable/myshape"/>    
</selector>

Java file

public class EditTextSelector extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}
