오픈 소스 프로젝트 PullToRefresh 상세 설명 (3) - PullToRefreshScrollView
24662 단어 scrollview
1. 레이아웃 파일
<?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" >
<!-- The PullToRefreshScrollView replaces a standard PullToRefreshScrollView widget. -->
<com.handmark.pulltorefresh.library.PullToRefreshScrollView
xmlns:ptr="http://schemas.android.com/apk/res-auto"
android:id="@+id/pull_refresh_scrollview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
ptr:ptrAnimationStyle="flip"
ptr:ptrMode="both" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="8dp"
android:text="@string/filler_text"
android:textSize="16sp" />
</com.handmark.pulltorefresh.library.PullToRefreshScrollView>
</LinearLayout>ScrollView 와 달리 리 니 어 레이아웃 으로 콘 텐 츠 를 만 드 는 용 기 를 넣 지 않 고 표시 할 것 을 넣 으 면 됩 니 다.
2. 컨트롤 을 찾 아 설정 합 니 다. 여기 Activity 코드 를 직접 붙 입 니 다.

1. 레이아웃 파일 은 textview 몇 개 입 니 다.

}여기 서 저희 가 이 부분 을 주목 해 보도 록 하 겠 습 니 다.
