public class AutoSwipeRefreshLayout extends SwipeRefreshLayout {    public AutoSwipeRefreshLayout(Context context) {        super(context);        init();    }    public AutoSwipeRefreshLayout(Context context, AttributeSet attrs) {        super(context, attrs);        init();    }    /**     * 初始化预设     */    private void init() {        setColorSchemeResources(android.R.color.holo_blue_bright,                android.R.color.holo_green_light,                android.R.color.holo_orange_light,                android.R.color.holo_red_light);        // 设置手指在屏幕下拉多少距离会触发下拉刷新        setDistanceToTriggerSync(400);    }    /**     * 调用该方法实现刷新 而无需滑动     */    public void autoRefresh() {        try {            Field mCircleView = SwipeRefreshLayout.class.getDeclaredField("mCircleView");            mCircleView.setAccessible(true);            View progress = (View) mCircleView.get(this);            progress.setVisibility(View.VISIBLE);//显示刷新控件            //自动刷新的缩放动画            ObjectAnimator animatorX = ObjectAnimator.ofFloat(progress, "scaleX", 0f, 1f);            ObjectAnimator animatorY = ObjectAnimator.ofFloat(progress, "scaleY", 0f, 1f);            animatorX.setDuration(500);            animatorY.setDuration(500);            animatorX.start();            animatorY.start();            Method setRefreshing = SwipeRefreshLayout.class.getDeclaredMethod("setRefreshing",                    boolean.class, boolean.class);            setRefreshing.setAccessible(true);            setRefreshing.invoke(this, true, true);//调用刷新方法        } catch (NoSuchFieldException e) {            e.printStackTrace();        } catch (IllegalAccessException e) {            e.printStackTrace();        } catch (NoSuchMethodException e) {            e.printStackTrace();        } catch (InvocationTargetException e) {            e.printStackTrace();        }    }}
