[ANDROID] 밑으로 당겨서 새로고침 하기

1. dependency 추가

implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"

 

2. 새로 고침 대상의 View를 SwipeRefreshLayout의 자식 View 만든다.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout
        android:id="@+id/swiperefreshlayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <WebView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/activity_main_webview"
            android:fadingEdge="none" />
    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

 

3. 소스에 이벤트 등록을 한다.

private SwipeRefreshLayout swipeRefreshLayout;
private WebView mWebView;

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        swipeRefreshLayout = findViewById(R.id.swiperefreshlayout);
        mWebView = findViewById(R.id.activity_main_webview);
        
        swipeRefreshLayout.setOnRefreshListener(() -> {
        	/* Webview를 새로고침한다. */
            mWebView.reload();
            /* 업데이트가 끝났음을 알림 */
            swipeRefreshLayout.setRefreshing(false);
        });
        
        ....
}
