Android實現了下拉刷新的自定義布局： CircleRefreshLayout

動畫的靈感來自于： https://dribbble.com/shots/1797373-Pull-Down-To-Refresh 。

<com.tuesda.walker.circlerefresh.CircleRefreshLayout
        xmlns:app="http://schemas.android.com/apk/res-auto"
        app:AniBackColor="#ff8b90af"
        app:AniForeColor="#ffffffff"
        app:CircleSmaller="6"
        android:id="@+id/refresh_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <ListView
            android:background="#ffffffff"
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        </ListView>
    </com.tuesda.walker.circlerefresh.CircleRefreshLayout>

在刷新開始和完成的時候回調：

mRefreshLayout.setOnRefreshListener(
                new CircleRefreshLayout.OnCircleRefreshListener() {
            @Override
            public void refreshing() {
                // do something when refresh starts
            }

            @Override
            public void completeRefresh() {
                // do something when refresh complete
            }
        });

在刷新完成的時候（比如，圖片加載完成），你可以觸發：

mRefreshLayout.finishRefreshing();
