爲mainactivity.java的示例代碼

package com.example.button_example; 

import android.net.Uri; 
import android.os.Bundle; 
import android.app.Activity; 
import android.content.Intent; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 

public class MainActivity extends Activity { 

    Button button; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     addListenerOnButton(); 

    } 

    public void addListenerOnButton() { 

     button = (Button) findViewById(R.id.button1); 

     button.setOnClickListener(new OnClickListener() { 

      public void onClick(View arg0) { 
       Intent browsercontent = new Intent(Intent.ACTION_VIEW, Uri.parse("google.com")); 
       startActivity(browsercontent); 


      } 
     }); 

    } 



} 

代碼activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Button - Go to mkyong.com" /> 

</LinearLayout>

嘗試添加協議的URI驗證碼：

new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com"));
