How check touch event


I searching about method which I check which way I touch screen and after that send information to touch event. I want to check if I touch screen one finger or two fingers or I move finger on screen. This is any method to check what I am doing my fingers on the screen befor application do some actions?


I think you can try this one.

A drag gesture starts when the first finger is pressed to the screen (<strong>ACTION_DOWN</strong>) and ends when it is removed (<strong>ACTION_UP</strong> or <strong>ACTION_POINTER_UP</strong>).

switch (event.getAction() & MotionEvent.ACTION_MASK) { case MotionEvent.ACTION_DOWN: savedMatrix.set(matrix); start.set(event.getX(), event.getY()); Log.d(TAG, "mode=DRAG" ); mode = DRAG; break; case MotionEvent.ACTION_UP: case MotionEvent.ACTION_POINTER_UP: mode = NONE; Log.d(TAG, "mode=NONE" ); break; case MotionEvent.ACTION_MOVE: if (mode == DRAG) { matrix.set(savedMatrix); matrix.postTranslate(event.getX() - start.x, event.getY() - start.y); } break; }
