Android Studio - Webview - shouldOverrideUrlLoading - 不要打开网络浏览器

Question

我使用 Android Studio 开发了一个 Webview 应用程序，但是当用户从 WebView 中的网页单击 link 时，Android 正在打开默认的 Web 浏览器。我已经查看了 Android 开发人员 API 指南如何操作，但它不起作用；（在我的应用程序上...指南 Link：Handling Page Navigation

谁知道如何使用 "shouldOverrideUrlLoading() method" 以及如何将其插入到我的实际应用程序中？

谢谢

// MainActivity.Java

package com.blabla.blabla;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.app.Application;
import com.parse.Parse;
import com.parse.ParseInstallation;


public class MainActivity extends ActionBarActivity {
    private WebView mWebView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mWebView = (WebView) findViewById(R.id.activity_main_webview);
        WebSettings webSettings = mWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        mWebView.loadUrl("http://www.blablablablablabla.com/");

        Parse.initialize(this, "ID Blablabla",
                "ID Blablabla");
        ParseInstallation.getCurrentInstallation()
                .saveInBackground();
    }

我修好了！我刚刚添加了

WebSettings webSettings = mWebView.getSettings();

和

private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

到我的 MainActivity.java 文件...非常棒！！！
