@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

        setListAdapter(new ArrayAdapter(this,

                android.R.layout.simple_list_item_1, mStrings));

}

@Override

protected void onListItemClick(ListView l, View v, int position, long id) {

// TODO Auto-generated method stub

Uri uri;

Intent i;

super.onListItemClick(l, v, position, id);

switch(position){

case 0:

            uri=Uri.parse("http://www.nkut.edu.tw");

            i=new Intent(Intent.ACTION_VIEW,uri);

            startActivity(i);

break;

case 1:

            uri = Uri.parse("http://nca.nantou.com.tw/?ptype=info");

            i = new Intent(Intent.ACTION_VIEW, uri);

            startActivity(i);

break;

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

}
