ViewFlipper 内的 listView - 滚动问题
我的 viewFlipper
中的 litView
遇到了一些问题。
// GestureDetector
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
return false;
// Right to left swipe
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
IconManager.INSTANCE.leftSwipe();
vf.setInAnimation(slideLeftIn);
vf.setOutAnimation(slideLeftOut);
vf.showNext();
System.out.println("SWIIINGG!!");
// Left to right swipe
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
IconManager.INSTANCE.rightSwipe();
vf.setInAnimation(slideRightIn);
vf.setOutAnimation(slideRightOut);
vf.showPrevious();
}
} catch (Exception e) {
// nothing
}
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
Log.e("Item Click","Item Click");
Intent intentAgenda = new Intent (Activity_Main.this, AgendaSelected.class);
//intentAgenda.putExtra("LECTURE_NAME", homeAgendaListAdapter.getItemId(3));
startActivity(intentAgenda);
return super.onSingleTapConfirmed(e);
}
}
此代码使我能够在翻转器中的视图之间翻转,并在不同翻转的列表中滚动。然而,这使得我的整个应用程序可点击。即使我在空白表面上singleTap
,它也会记录一次点击,并将我发送到IntentintentAgenda = new Intent
想要发送给我的位置。仅当我点击 listView
中的项目时才会发生这种情况!
我该怎么做才能让特定列表上的侦听器仅侦听“列表上”而不是整个应用程序?我相信问题出在 public boolean onSingleTapConfirmed
中,但我看不到它。
I'm having some trouble with my litView
inside my viewFlipper
.
// GestureDetector
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
return false;
// Right to left swipe
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
IconManager.INSTANCE.leftSwipe();
vf.setInAnimation(slideLeftIn);
vf.setOutAnimation(slideLeftOut);
vf.showNext();
System.out.println("SWIIINGG!!");
// Left to right swipe
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
IconManager.INSTANCE.rightSwipe();
vf.setInAnimation(slideRightIn);
vf.setOutAnimation(slideRightOut);
vf.showPrevious();
}
} catch (Exception e) {
// nothing
}
return false;
}
@Override
public boolean onSingleTapConfirmed(MotionEvent e) {
Log.e("Item Click","Item Click");
Intent intentAgenda = new Intent (Activity_Main.this, AgendaSelected.class);
//intentAgenda.putExtra("LECTURE_NAME", homeAgendaListAdapter.getItemId(3));
startActivity(intentAgenda);
return super.onSingleTapConfirmed(e);
}
}
This code enables me to flip among the views in the flipper and scroll in the lists within the different flips. However, this makes my entire app clickable. Even if I singleTap
on a blank surface, it registers a click, and sends me to where the Intent intentAgenda = new Intent
wants to send me. This should only happen when I tap on an item within the listView
!
What can I do to get the listener on the specific lists to only listen "on the lists" and not the entire app? I believe that the problem lies within the public boolean onSingleTapConfirmed
, but I can't see it.

我没有尝试过上述方法,但实际有效的一种解决方案是创建一个新的 OnItemClickListener,然后在列表上 setOnItemClickListener(您的项目单击侦听器)。
这就是在您的情况下不使用单击,而只是创建一个新的 itemclick 侦听器,如下所示,但更时尚:
如果您想创建更多列表,您可以创建一个新的项目单击侦听器,然后将每个列表指向它。
I have not tried the above but one solution that actually work is to create a new OnItemClickListener and then setOnItemClickListener(your item click listener) on your lists.
That would be to not use single tap in your case but just create a new on itemclick listener like this but more stylish:
If you want to create more lists you can create a new item click listener and just point every list to it.
由于包含列表的 ViewFlipper 具有相同的gestureListener,因此 viewflipper 中被点击的所有内容都会触发 onSingleTapConfirmed() 方法。尝试在单独的gesturelistner 上注册列表以仅处理点击:) 感觉问题不是在此代码块中,而是设置gestureListners等的位置。
Since the ViewFlipper containing the lists has the same gestureListener, everything within the viewflipper that is tapped will trigger the onSingleTapConfirmed() method.. Try registering the lists on a seperate gesturelistner aswell to handle the taps only :) Feels like the problem isn't in this codeblock but rather where the gestureListners etc is set.
