Use Xml to config

Since v1.4.1
<?xml version="1.0" encoding="utf-8"?>
<me.dkzwm.widget.srl.SmoothRefreshLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:app="http://schemas.android.com/apk/res-auto"
	android:id="@+id/smoothRefreshLayout"
	android:layout_width="match_parent"
	android:layout_height="match_parent">
	<TextView
		android:layout_width="match_parent"
		android:layout_height="match_parent"/>
</me.dkzwm.widget.srl.SmoothRefreshLayout>
Before v1.4.1
<?xml version="1.0" encoding="utf-8"?>
<me.dkzwm.smoothrefreshlayout.SmoothRefreshLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:app="http://schemas.android.com/apk/res-auto"
	android:id="@+id/smoothRefreshLayout"
	android:layout_width="match_parent"
	android:layout_height="match_parent">
	<TextView
		android:layout_width="match_parent"
		android:layout_height="match_parent"/>
</me.dkzwm.smoothrefreshlayout.SmoothRefreshLayout>

Use Java code to config

SmoothRefreshLayout refreshLayout = (SmoothRefreshLayout)findViewById(R.id.smoothRefreshLayout);
refreshLayout.setMode(SmoothRefreshLayout.MODE_BOTH);
refreshLayout.setHeaderView(new ClassicHeader(this));
refreshLayout.setOnRefreshListener(new RefreshingListenerAdapter() {
	@Override
	public void onRefreshBegin(boolean isRefresh) {
		mHandler.postDelayed(new Runnable() {
			@Override
			public void run() {
				refreshLayout.refreshComplete();
			}
		}, 4000);
	}
});

Custom refresh view

Interface define
public interface IRefreshView {    

    byte TYPE_HEADER = 0;
    byte TYPE_FOOTER = 1;

    byte STYLE_DEFAULT = 0;
    byte STYLE_SCALE = 1;

    /**
     * Get the view's type.
	 * @return type {@link #TYPE_HEADER}, {@link #TYPE_FOOTER}.
     */
    int getType();

    /**
     * Get the target view.
     *
     * @return The returned view must be the view that will be added to the Layout
     */
    View getView();

    /**
     * Get the view's style. If return {@link #STYLE_SCALE} SmoothRefreshLayout will dynamically
     * change the height, so the performance will be reduced.
     *
     * @return style {@link #STYLE_DEFAULT}, {@link #STYLE_SCALE}.
     */
    int getStyle();

    /**
     * Get the custom height, If style is {@link #STYLE_SCALE} should return a custom height.
     *
     * @return Custom height
     */
    int getCustomHeight();

    /**
     * This method will be triggered when the touched finger is lifted.
     *
     * @param layout    The layout {@link SmoothRefreshLayout}
     * @param indicator The indicator {@link IIndicator}
     */
    void onFingerUp(SmoothRefreshLayout layout, IIndicator indicator);

    /**
     * This method will be triggered when the refresh state is reset to
     * {@link SmoothRefreshLayout#SR_STATUS_INIT}.
     *
     * @param layout The layout {@link SmoothRefreshLayout}
     */
    void onReset(SmoothRefreshLayout layout);

    /**
     * This method will be triggered when the frame is ready to refreshing.
     *
     * @param layout The layout {@link SmoothRefreshLayout}
     */
    void onRefreshPrepare(SmoothRefreshLayout layout);

    /**
     * This method will be triggered when the frame begin to refresh.
     *
     * @param layout    The layout {@link SmoothRefreshLayout}
     * @param indicator The indicator {@link IIndicator}
     */
    void onRefreshBegin(SmoothRefreshLayout layout, IIndicator indicator);

    /**
     * This method will be triggered when the frame is refresh completed.
     *
     * @param layout       The layout {@link SmoothRefreshLayout}
     * @param isSuccessful The layout refresh state
     */
    void onRefreshComplete(SmoothRefreshLayout layout,boolean isSuccessful);

    /**
     * This method will be triggered when the position of the refresh view changes.
     *
     * @param layout    The layout {@link SmoothRefreshLayout}
     * @param status    Current status @see{@link SmoothRefreshLayout#SR_STATUS_INIT},
     *                  {@link SmoothRefreshLayout#SR_STATUS_PREPARE},
     *                  {@link SmoothRefreshLayout#SR_STATUS_REFRESHING},
     *                  {@link SmoothRefreshLayout#SR_STATUS_LOADING_MORE},
     *                  {@link SmoothRefreshLayout#SR_STATUS_COMPLETE}.
     * @param indicator The indicator {@link IIndicator}
     */
    void onRefreshPositionChanged(SmoothRefreshLayout layout, byte status, IIndicator indicator);

}

    setHeaderView(@NonNull IRefreshView header);
    setFooterView(@NonNull IRefreshView footer);
  • Please write directly to the Xml file,SmoothRefreshLayout will find the view that impl the IRefreshView interface to added inside.
