Question

I’ve got a Activty which is displayed after a info-button is pressed. Now I want to close/ destroy the activty, when the user touches the screen, so that the user can get back to the main-activty again, without pressing the back-button of the device. How does the code look like.

I tried this, but it has no effect:

if(onTouchEvent(null)){
        finish();
}

Thanks.

EDIT:

This is the whole code I have:

public class InfoDialog extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.info_dialog); }

I use this Class just to show a short Information about the App with in the android-style of Theme.Dialog
However, I want to add one function, to destroy/ close this activty, when the touchscreen is pressed, so that there is no need to press the back-button.

Try this…

LinearLayout mainLayout = (LinearLayout) findViewById(R.id.mainLayoutId);

mainLayout.setOnTouchListener(new OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event) {
                int eid = event.getAction();
                switch (eid) {
                case MotionEvent.ACTION_DOWN:
                    finish();
                    break;
                }
                return true;
            }
        });
