Do you really need add an EditText programmatically?

Usually it is enough to hide certain Views and change the visibility programmatically.

<EditText android:id="@+id/view_name"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:visibility="gone"
        />

The three values for visibility are "visible", "invisible" and "gone". "gone" means the EditText is taking no space. "invisible" means that the space it would take is empty.

You can change the visibility the following way:

EditText editText = (EditText) findViewById(R.id.view_name);
editText.setVisibility(View.VISIBLE);
