如何使用指定浏览器打开网页

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.2cto.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
