Answer 1

If you just want to "display an edit text box on click of a button" why don't you just..

Keep the EditText in your XML layout file for that activity below the Button where you want it..

XML set it's

android:visibility = "gone"

and making instance of that

EditText et=(EditText)findViewById(R.id.thatEditText);

in activity...in your button click event set

et.setVisibility(View.VISIBLE);

Define the view in your layout, then in code, show and hide it with myView.setVisibility(View.VISIBLE) and myView.setVisibility(View.GONE).

    //xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

<Button 
    android:id="@+id/btn"
  android:layout_width="fill_parent"
    android:layout_height="wrap_content"  
    android:text="Button"
    />
<EditText 
   android:id="@+id/edtbox"
  android:layout_width="fill_parent"
    android:layout_height="wrap_content"    


    />
</LinearLayout>


//Activity

//oncreate

editText.setVisibility(View.GONE);

btn..setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    editText.setVisibility(View.VISIBLE);
                }
            });

Answer 4

If your layout is relative then addView(yourView, index) doesn't work. Suppose you want to add view after some other control and reference to that control.

e.g.

<RelativeLayout android:id="@+id/templayout">
   <Button android:id="@+id/button"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="add"/>

and you want to add edit text control after text View then on button click :

RelativeLayout relativeLayout = (RelativeLayout)findViewById(R.id.templayout);
    RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);

    params.addRule(RelativeLayout.BELOW, R.id.title);
    EditText yourEditText = new EditText(this);
    relativeLayout.addView(yourEditText, params);

Answer 5

Define your EditText in your xml and hide it. On button click, change its visibility to View.Visible.

 YourEditText.setVisibility(View.GONE);

 btn.setOnClickListener(new View.OnClickListener() 
     {
        public void onClick(View v)
         {              
          YourEditText.setVisibility(View.VISIBLE);
          }
       });
