SwipeRefreshLayout简单说明

SwipeRefreshLayout是谷歌官方的下拉刷新控件，代码在V4包中。java

使用SwipeRefreshLayout有几个要注意的：android

1. SwipeRefreshLayout和ScrollView同样只能有一个字控件。ide

2. setOnRefreshListener设置监听刷新。spa

3. setProgressBackgroundColor设置刷新时圆形进度条的背景色code

4. setColorSchemeResources设置刷新时进度条颜色xml

5. setRefreshing设置刷新状态事件

6. setSize设置大小，如今只有SwipeRefreshLayout.DEFAULT，SwipeRefreshLayout.LARGEip

若是在SwipeRefreshLayout的子控件中嵌套了其余可滚动控件例如get

 <android.support.v4.widget.SwipeRefreshLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
                <ScrollView
                    android:layout_width="match_parent"
                    android:layout_height="0dip"
                    android:layout_weight="1"
                    android:id="@id/svCar"
                    android:fadingEdge="none" >
                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"/>
                </ScrollView>
                    <TextView
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"/>
        </LinearLayout>        
</android.support.v4.widget.SwipeRefreshLayout>

当ScrollView滚动到下方后，向下拉ScrollView不会滚动而会出现下拉刷新动做，这时须要将ScrollView设置onTouch事件
it

    OnTouchListener onTouchListener=new OnTouchListener() {
        
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
            case MotionEvent.ACTION_MOVE:
            case MotionEvent.ACTION_UP:
                if (svCar.getScrollY() > 0) {
                    srlCar.setEnabled(false);
                } else {
                    srlCar.setEnabled(true);
                }
                break;
            }
            return false;
        }
    };
