问题:

I want to go to a web page on the click of a button in my Android app. So say, I have a button called "Google", when the user clicks on that button I want google.com to open up on the screen. How is this achieved?

Also, is there a way I can gain control back to my app once the user is finished with Google?

回答1:

In your activity do something like this.

public void openWebURL( String inURL ) {
    Intent browse = new Intent( Intent.ACTION_VIEW , Uri.parse( inURL ) );

    startActivity( browse );
}

By default, quitting the browser should return to your activity. However, there may be situations where it will not.

This code will take you to the web page

public void goToWebPage(String yourUrl) 
{
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse(yourUrl));
    startActivity(intent);
}
