Android ViewFlipper + homescreen animation
- by Tim
I am trying to use a ViewFlipper and make it act like the home screen(The layout will move with your finger). Check out this for an example. I want to do this with a ViewFlipper that only contains two children so the opposite view should be shown on either side of the current view depending on which way the user moves their finger. This code works but only for 1 direction at a time. This is in onTouchEvent.
case MotionEvent.ACTION_MOVE:
leftView.setVisibility(View.VISIBLE);
rightView.setVisibility(View.VISIBLE);
// move the current view to the left or right.
currentView.layout((int) (touchEvent.getX() - oldTouchValue),
currentView.getTop(),
(int) (touchEvent.getX() - oldTouchValue) + 320,
currentView.getBottom());
// place this view just left of the currentView
leftView.layout(currentView.getLeft() - 320, leftView.getTop(),
currentView.getLeft(), leftView.getBottom());
// place this view just right of the currentView
rightView.layout(currentView.getRight(), rightView.getTop(),
currentView.getRight() + 320, rightView.getBottom());
Which ever of the bottom two lines I put last that direction will work correctly but the other will not.
Here is how I set the leftView and rightView:
final View currentView = myFlipper.getCurrentView();
final View leftView, rightView;
if (currentView == meView) {
Log.d("current layout: ", "me");
leftView = youView;
rightView = youView;
} else if (currentView == youView) {
Log.d("current layout: ", "you");
leftView = meView;
rightView = meView;
}else {
leftView = null;
rightView = null;
}
Is it going to be possible to set it up so that the same view is shown on both sides of the current view?
