为什么这在更改 Web 视图的 URL 时不起作用(已解决但它现在正在打开一个新的浏览器 window 而不是将其保留在应用程序中???)

Why won't this work at changing the URL of a web View (resolved but it is now opening a new browser window instead of keeping it in the app???)

我正在制作作品集,我希望它更改为新的 URL 以在您单击“下一步”或 nextButton(mNextButton 变量)后加载。这是带有 webview 的 activity 的代码。

package com.dredaydesigns.dredaycreativeportfolio;

import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.webkit.WebView;
import android.widget.ImageView;
import android.widget.Button;
import android.R.id;


import static com.dredaydesigns.dredaycreativeportfolio.R.layout.activity_content_activity;


public class content_activity extends ActionBarActivity {
    private WebView mWebView;
    private Button mNextButton;
    private String webURL = "http://extremesportsshows.com/"


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(activity_content_activity);
        String backgroundColor = getIntent().getExtras().getString("webColor");
        ImageView iv = (ImageView) findViewById(R.id.subBanner);
        iv.setBackgroundColor(Color.parseColor(backgroundColor));
        mWebView = (WebView) findViewById(R.id.webView);
        mWebView.loadUrl("webURL");

        mNextButton= (Button) findViewById(R.id.nextButton);

        mNextButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                webURL = "http://www.betterup.co/";


            }
        });
 }

这是 activity_content_activity

的 xml 代码

首先,您的 WebView 根本不会加载网页,因为以下行

mWebView.loadUrl("webURL");

错了。您应该将一个字符串对象传递给存储在 webURL 字符串中的 loadUrl() method, and that string should be the url that you want to load. In your case its http://extremesportsshows.com/。所以你的代码应该是这样的。

mWebView.loadUrl(webURL); // Without the quotes

点击下一步后,您将再次加载 WebView 中的 url,如下所示

mNextButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                webURL = "http://www.betterup.co/";
                mWebView.loadUrl(webURL);
            }
        });
