        android:layout_alignParentStart="true" />
</RelativeLayout>

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


Solution

  • You could wrap webview in Swipe refesh 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();
        }
        }
        );
    
    }
    
    }
