J'ai fait une réponse en utilisant ce que macloving a écrit. Pour l'instant, cela fonctionne, mais seulement si tous vos enfants ont la même hauteur.
listView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
historicX = event.getX();
historicY = event.getY();
return false;
case MotionEvent.ACTION_UP:
if (listView.getChildAt(0) != null) {
int heightOfEachItem = haveListView.getChildAt(0).getHeight();
int heightOfFirstItem = -haveListView.getChildAt(0).getTop() + haveListView.getFirstVisiblePosition()*heightOfEachItem;
//IF YOU HAVE CHILDS IN LIST VIEW YOU START COUNTING
//listView.getChildAt(0).getTop() will see top of child showed in screen
//Dividing by height of view, you get how many views are not in the screen
//It needs to be Math.ceil in this case because it sometimes only shows part of last view
final int firstPosition = (int) Math.ceil(heightOfFirstItem / heightOfEachItem); // This is the same as child #0
//Here you get your List position, use historic Y to get where the user went first
final int wantedPosition = (int) Math.floor((historicY - haveListView.getChildAt(0).getTop()) / heightOfEachItem) + firstPosition;
//Here you get the actually position in the screen
final int wantedChild = wantedPosition - firstPosition;
//Depending on delta, go right or left
if (event.getX() - historicX < -DELTA) {
//If something went wrong, we stop it now
if (wantedChild < 0 || wantedChild >= List.size()|| wantedChild >= listView.getChildCount()) {
return true;
}
//Start animation with 500 miliseconds of time
listView.getChildAt(wantedChild).startAnimation(outToLeftAnimation(500));
//after 500 miliseconds remove from List the item and update the adapter.
new java.util.Timer().schedule(
new java.util.TimerTask() {
@Override
public void run() {
List.remove(wantedPosition);
updateAdapter();
}
},
500
);
return true;
} else if (event.getX() - historicX > DELTA) {
//If something went wrong, we stop it now
if (wantedChild < 0 || wantedChild >= List.size() || wantedChild >= listView.getChildCount()) {
return true;
}
//Start animation with 500 miliseconds of time
listView.getChildAt(wantedChild).startAnimation(outToRightAnimation(500));
//after 500 miliseconds remove from List the item and update the adapter.
new java.util.Timer().schedule(
new java.util.TimerTask() {
@Override
public void run() {
List.remove(wantedPosition);
updateAdapter();
}
},
500
);
return true;
}
}
return true;
default:
return false;
}
}
});
Les animations ont cette fonction :
private Animation outToLeftAnimation(int duration) {
Animation outtoLeft = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, -1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f);
outtoLeft.setDuration(duration);
outtoLeft.setInterpolator(new AccelerateInterpolator());
return outtoLeft;
}
private Animation outToRightAnimation(int duration) {
Animation outtoRight = new TranslateAnimation(
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, +1.0f,
Animation.RELATIVE_TO_PARENT, 0.0f,
Animation.RELATIVE_TO_PARENT, 0.0f);
outtoRight.setDuration(duration);
outtoRight.setInterpolator(new AccelerateInterpolator());
return outtoRight;
}
J'essaie ceci, et jusqu'à présent je n'ai pas vu d'erreurs, si quelqu'un pouvait essayer aussi, ce serait bien.
