위처럼 파씽을 하여 데이터를 다른 슬라이드에서 출력하려하는데 text의 값이 계속 null이 뜹니다.
sub_view1, sub_view2, sub_view3는 각각 xml이구요. main_activity는 따로 있습니다.
sub_view2가 다음과 같이 textView를 가지고 있습니다.
<?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" >
<TextView
android:id="@+id/sub_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="sub_view2" />
</LinearLayout>
왜 text값이 계속 null 이 나온는 것일까요?
