[안드로이드] 아래로 당겨 새로고침 Swipe refresh layout

참고할 글이 있었는데 다소 오래된 것들이라 삽질을 좀 했다. 

 

 

1. gradle 에 dependency 추가

 

dependencies {
    // Swipe Refresh Layout
    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"
}

 

 

2. ListView나 RecyclerView 감싸주기 

 

    <androidx.swiperefreshlayout.widget.SwipeRefreshLayout

        android:id="@+id/content_srl"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1">

        <ListView
            android:id="@+id/content_lv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

 

 

3. java 파일에서 setOnRefreshListener 오버라이드 해주기.

 

public class NewsActivity extends AppCompatActivity {

	private SwipeRefreshLayout mysrl;
    
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
   
        mysrl = findViewById(R.id.content_srl);
        mysrl.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
            	// 새로고침시 동작 
                new RssThread().start();
                
                // 종료
                mysrl.setRefreshing(false);
            }
        });
        
    }
}
