SwipeRefreshLayout 與 CoordinatorLayout 嵌套刷新

SwipeRefreshLayout 與 CoordinatorLayout 嵌套刷新
 1. 動態設置SwipeRefreshLayout的是否能夠刷新 setEnable(boolean isEnable);
 2. 設置SwipRefreshLayout刷新圖標的位置 setProgressViewOffset(true, -20, 100);

 首先看 SwipeRefreshLayout 與 CoordinatorLayout 佈局:
 1) SwipeRefreshLayout 做爲最外層佈局
 2) CoordinatorLayout 做爲第二次佈局
 3) CoordinatorLayout 中嵌套 AppBarLayout 及 ListView 或 RecyclerView 注意 app:layout_behavior="@string/appbar_scrolling_view_behavior",
 因爲 CoordinatorLayout 是 FrameLayout 子類所以 app:layout_behavior 爲必要屬性，不然沒法正常顯示

<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/swipe_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:addStatesFromChildren="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/coord_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true">

        <android.support.design.widget.AppBarLayout
            android:id="@+id/appbar_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:clipChildren="false">

            <android.support.design.widget.CollapsingToolbarLayout
                android:id="@+id/collapsing_toolbar_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:clipChildren="false"
                android:theme="@style/AppTheme.AppBarOverlay"
                app:contentScrim="?attr/colorPrimary"
                app:expandedTitleMarginStart="10dp"
                app:layout_scrollFlags="scroll|exitUntilCollapsed">

                <android.support.v4.view.ViewPager
                    android:id="@+id/toolbar_viewpager"
                    android:layout_width="match_parent"
                    android:layout_height="180dp"
                    android:layout_marginLeft="15dp"
                    android:layout_marginRight="15dp"
                    android:clipChildren="false"
                    app:layout_collapseParallaxMultiplier="1" />

                <android.support.v7.widget.Toolbar
                    android:id="@+id/toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    app:layout_collapseMode="pin"
                    app:layout_scrollFlags="scroll|enterAlways"
                    app:popupTheme="@style/AppTheme.PopupOverlay">

                </android.support.v7.widget.Toolbar>

            </android.support.design.widget.CollapsingToolbarLayout>

        </android.support.design.widget.AppBarLayout>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    </android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.SwipeRefreshLayout>
 3.設置 SwipeRefreshLayout
    mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_layout);
        mSwipeRefreshLayout.setOnRefreshListener(this);
        //設置樣式刷新顯示的位置
        mSwipeRefreshLayout.setProgressViewOffset(true, -20, 100);
        mSwipeRefreshLayout.setColorSchemeResources(R.color.swiperefresh_color1, R.color.swiperefresh_color2, R.color.swiperefresh_color3, R.color.swiperefresh_color4);
   
    4.監聽 AppBarLayout Offset 變化，動態設置 SwipeRefreshLayout 是否可用
     appBarLayout = (AppBarLayout) findViewById(R.id.appbar_layout);
        appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
            @Override
            public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {

                if (verticalOffset >= 0) {
                    mSwipeRefreshLayout.setEnabled(true);
                } else {
                    mSwipeRefreshLayout.setEnabled(false);
                }
            }
        });
