私はOnGestureListener自分のクラスで使用しています。自分が行ったジェスチャが時計回りか反時計回りかを調べ、それらのジェスチャでさまざまなタスクを実行したいと考えています。OnGestureListenerこの機能を提供していますか? これどうやってするの？

 if(prediction.size() > 0){
  String gesturePerformed = prediction.get(0).name;
  if(gesturePerformed.equals("up")){
   myForeground.canvasUp();
   Toast.makeText(MyGameActivity.this,
     "up", Toast.LENGTH_LONG).show();
  }else if(gesturePerformed.equals("down")){
   myForeground.canvasDown();
   Toast.makeText(MyGameActivity.this,
     "down", Toast.LENGTH_LONG).show();
  }else if(gesturePerformed.equals("left")){
   myForeground.canvasLeft();
   Toast.makeText(MyGameActivity.this,

  }else if(gesturePerformed.equals("right")){
   myForeground.canvasRight();
   Toast.makeText(MyGameActivity.this,

  }else if(gesturePerformed.equals("enlarge")){
   myForeground.canvasEnlarge();
   Toast.makeText(MyGameActivity.this,

  }else if(gesturePerformed.equals("reduce")){
   myForeground.canvasReduce();
   Toast.makeText(MyGameActivity.this,
