Question

I am developing an Android application and I need to handle various touch events.

Consider the following requirements:

• If the user touches on the right side of the screen I want to display next screen.

• If user touches on the left side of the screen I want to display previous screen.

On the whole I have about 25 screens.

How can I get the logical coordinates of the screen and trigger the required event?

Answer 1

Override
public boolean onTouchEvent(MotionEvent event) {

     float x =event.getRawX();
     float y =event.getRawY();
     return super.onTouchEvent(event);
}

Note : getX() and getY(), returns the position(x,y) of touch in relation with the View, getRawX() and getRawY() returns the position ( x,y ) in relation of the screen of your Android phone.
