Adding stretch to update in the web review for update

I will add an update link in my web browser to update my web view. I saw all the questions on this page, but I can not find a good way to add pull to update ...

Mainactivity.java

package com.vvhvb.hesselfeenstra.vvheerenveenseboys;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String url ="http://heerenveenseboys.nl/";
        WebView view=(WebView) this.findViewById(R.id.webView);
        view.getSettings().setJavaScriptEnabled(true);
        view.getSettings().setBuiltInZoomControls(true);
        view.getSettings().setDisplayZoomControls(false);
        view.setWebViewClient(new WebViewClient());
        view.loadUrl(url);

    }

}

content_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.vvhvb.hesselfeenstra.vvheerenveenseboys.MainActivity"
    tools:showIn="@layout/activity_main">

    <WebView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/webView"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />
</RelativeLayout>

I hope someone can help me and solve this problem for me.

You can wrap the webview in a Swipe repository layout like this

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.vvhvb.hesselfeenstra.vvheerenveenseboys.MainActivity"
tools:showIn="@layout/activity_main">

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipeContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/webView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true" />

</android.support.v4.widget.NestedScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>

In java

package com.vvhvb.hesselfeenstra.vvheerenveenseboys;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {
WebView view;
SwipeRefreshLayout mySwipeRefreshLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mySwipeRefreshLayout = (SwipeRefreshLayout)this.findViewById(R.id.swipeContainer);
    String url ="http://heerenveenseboys.nl/";
    view=(WebView) this.findViewById(R.id.webView);
    view.getSettings().setJavaScriptEnabled(true);
    view.getSettings().setBuiltInZoomControls(true);
    view.getSettings().setDisplayZoomControls(false);
    view.setWebViewClient(new WebViewClient());
    view.loadUrl(url);

    mySwipeRefreshLayout.setOnRefreshListener(
    new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {
        view.reload();
    }
    }
    );

}

Try this if you just want to click to update

    ll = (LinearLayout)findViewById(R.id.CategorySelect_lLayout_noID);
ll.setOnTouchListener(new OnTouchListener() {

    public boolean onTouch(View v, MotionEvent event) {

        if(event.getAction() == MotionEvent.ACTION_DOWN){
            Toast.makeText(CategorySelect.this, "action DOWN called", Toast.LENGTH_SHORT).show();
            return true;
        } 

        return false;
    }
});
    return true;
}

Or if you need an icon or something like chrome
