How to use SpringView

Add Spring View in the layout file, note that Spring View and ScrollView have the same limitation: only one child element：

	<com.liaoinstan.springview.widget.SpringView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:header="@layout/myheader"
            app:footer="@layout/myfooter">

            <ListView RecyclerView ScrollView or others
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>

     </com.liaoinstan.springview.widget.SpringView>

Of course, you can also add the header/footer in java code：

	springView.setHeader(new DefaultHeader(this));
	springView.setFooter(new DefaultFooter(this));

Add Listener

If you need to deal with the case, just add a listener in code：

springView.setListener(new SpringView.OnFreshListener() {
      @Override
      public void onRefresh() {
      }
      @Override
      public void onLoadmore() {
      }
});

Get SpringView

use Gradle:

dependencies {

   //SpringView core library (only include DefaultHeader/Footer)
   implementation 'com.liaoinstan.springview:library:1.7.0'

   //other Headers/Footers, choose one or more that you like
