This is described in the Dev Guide (
http://developer.android.com/guide/topics/ui/ui-events.html
)
// Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
}
};
protected void onCreate(Bundle savedValues) {
...
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
...
}
You can also do it inline if you wanted:
button.setOnClickListener(new View.OnClickListener() {
public void onClick(final View v) {
// do something here
}
});
To call another Activity you can do something like this in your onClick:
Intent i = new Intent(this, OtherActivityName.class);
i.putExtra(String id, String value); // if needed to pass info between
the two activities
startActivityForResult(i,int id);
