RefreshableView

可下拉刷新的ViewGroup、ListView

RefreshableView:

main_xml:

  <com.wangjie.refreshableview.RefreshableView
            xmlns:rv="http://schemas.android.com/apk/res/com.wangjie.refreshableview"
            android:id="@+id/main_refresh_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            rv:interceptAllMoveEvents="false"
            >
        <com.wangjie.refreshableview.NestScrollView android:layout_width="match_parent" android:layout_height="wrap_content"
                android:fillViewport="true"
                >
            <TextView
                    android:id="@+id/main_tv"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:gravity="center"
                    android:padding="20dp"
                    android:textSize="18sp"
                    android:text="Drop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh\nDrop Down For Refresh\n\n\n\n\n\n\n\n\n\n\nDrop Down For Refresh"
                    />
        </com.wangjie.refreshableview.NestScrollView>
    </com.wangjie.refreshableview.RefreshableView>

注意:RefreshableView如果包含在ScrollView外面,需要设置属性“interceptAllMoveEvents”为false
