Which user action causes a click event

Question

A click event on a desktop is normally generated, when the user clicks with a mouse. But you dont use a mouse with a smartphone.

So far I didnt find way to generate a click event on my touchscreen. Are there certain hardware features, whith which you can "click"?

First, you can't get UI click events when user on Android phone clicks "desktop" (home screen). You only get click events when user clicks something in your app.

Taken from Handling UI Events tutorial:

// 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);
    ...
}
