      }
});

@Override

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

In your Java file write the following piece of code...

ImageView Button = (ImageView)findViewById(R.id.yourButtonsId);

Button.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);
        intent.setData(Uri.parse("http://www.yourURL.com"));
        startActivity(intent);
    }
});

Answer 3

Import import android.net.Uri;

Intent openURL = new Intent(android.content.Intent.ACTION_VIEW);
openURL.setData(Uri.parse("http://www.example.com"));
startActivity(openURL);

or it can be done using,

TextView textView = (TextView)findViewById(R.id.yourID);

textView.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);
        intent.setData(Uri.parse("http://www.typeyourURL.com"));
        startActivity(intent);
    } });

Here is a workable answer.

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.tutorial.todolist"
  android:versionCode="1"
  android:versionName="1.0">
  <uses-sdk android:minSdkVersion="3"></uses-sdk>
  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".todolist"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
  </application>
</manifest>

todolist.java

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

public class todolist extends Activity {    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button btn = (Button) findViewById(R.id.btn_clickme);
        btn.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent myWebLink = new Intent(android.content.Intent.ACTION_VIEW);
                myWebLink.setData(Uri.parse("http://www.anddev.org"));
                    startActivity(myWebLink);
             }
        });
    }
}

main.xml

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

    <Button android:id="@+id/btn_clickme" 
      android:text="Click me..." 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" /> 
</LinearLayout>
