如何使用指定浏览器打开网页

刚刚看到一道Android面试题：如果使用制定的浏览器打开网页。
网上讲解的都比较简单，其实确实很简单，主要就是设置一下intent就可以，不过这里，我们讲解一些附带的知识。
就是查看一下本机上可用的浏览器，因为之前做过检测语音识别程序时需要检测Google 语音命令，这里简单的修改了一下就可以查看了。
具体代码如下：

package com.google.code.cakedroid.demo;

import java.util.List;

import com.google.code.cakedroid.R;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.net.Uri;
import android.os.Bundle;

public class BrowserDemo extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        // get the view web intent
        Intent intent = this.getViewWebIntent();
        this.printInterestedActivitiesByIntent(intent);
        // set the className to use the specific browser to open the webpage.
        intent.setClassName("com.tencent.mtt", "com.tencent.mtt.MainActivity");
        startActivity(intent);
    }

    /*
     *get the desired view web intent
     */
    private Intent getViewWebIntent() {
        Intent viewWebIntent = new Intent(Intent.ACTION_VIEW);
        Uri uri = Uri.parse("http://www.zzzyk.com");

        viewWebIntent.setData(uri);
        return viewWebIntent;
    }

    /*
     * print the activities that are interested about the intent
     */
    private void printInterestedActivitiesByIntent(Intent intent) {
        PackageManager pm = this.getPackageManager();
        List<ResolveInfo> activities = pm.queryIntentActivities(intent, 0);
        if (null != activities) {
            for (int i = 0; i < activities.size(); i++) {
                ResolveInfo info = activities.get(i);
                System.out.println(info.activityInfo.name);
            }
        } else {
            System.out.println("no interested activities");
        }
    }

}

输出结果为：
12-17 05:02:30.096: I/System.out(217): com.android.browser.BrowserActivity
12-17 05:02:30.096: I/System.out(217): com.tencent.mtt.MainActivity
12-17 05:02:30.096: I/System.out(217): cn.dolphin.browser.BrowserActivity
