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
