我将在我的webview上添加pull刷新,以便刷新我的webview.我在这个页面上看到了所有问题,但我找不到添加拉动刷新的好方法......

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

    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>

我希望有人能帮助我并为我解决这个问题.

我想在我的应用上添加一个分享按钮.

如果用户使用该应用程序,他们可以选择共享我的应用程序,但不幸的是,它没有发生.

这是我的代码:

MainActivity.java

package com.vvhvb.hesselfeenstra.vvheerenveenseboys;

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.app.AppCompatActivity;
import android.widget.ShareActionProvider;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

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

    }

    private ShareActionProvider mShareActionProvider;
    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_main, menu);
        MenuItem item = menu.findItem(R.id.menu_item_share);
        mShareActionProvider = (ShareActionProvider)MenuItemCompat.getActionProvider(item);
        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        String …
