Question

I have created some buttons in XML and I have method that will onClick open a URL. How do I link this method to my button so that on tap/onClick it will call the method.

Here’s the method code:

    public void openResource() {
     Uri uri = Uri.parse("http://librarywales.org");
     Intent intent = new Intent(Intent.ACTION_VIEW, uri);
     startActivity(intent);
}

And I have created an instance of my XML Button in the onCreate method:

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

    Button libButton = (Button) findViewById(R.id.button1);
}

How do I add that method to the libButton instance?

I have now solved the above issue with the help of ‘vins’ but when I run this application on the AVD and click on a button it pops up with an android message box saying. ‘Unfortunately, ApplicationName has stopped working.’

Anyone know why this is?

Thanks,
Dan

Answer 1

public class YourActivity extends Activity  implements OnClickListener {
     public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

   Button libButton =(Button) findViewById(R.id.button1);
    libButton.setOnClickListener(this);

    Button OtherButton =(Button) findViewById(R.id.button2);
    OtherButton.setOnClickListener(this);


   }

 @Override
  public void onClick(View v) {

    switch (v.getId()) {
    case R.id.button1: openResource();
                           break;
    case R.id.button2: //do something for second button...

     default : break;
         }
