LL2.setVisibility(View.GONE);

}else{

}
}
onCreate（）中获取LL1、LL2、LL3：
我相信这样的方法可以奏效：
private int mPosition = 0;
private View[] mPages; // instantiate and populate this in onCreate
private void showNext() {
show(false, mPages[mPosition]);
show(true, mPages[++mPosition]);
}
private void showPrevious() {
show(false, mPages[mPosition]);
show(true, mPages[--mPosition]);
}
@Override
public void onBackPressed() {
showPrevious();
}
private static void show(final boolean show, final View view) {
final int visibility = show ? View.VISIBLE : View.GONE;
view.setVisibility(visibility);
}
当然，您必须确保mPosition
已正确绑定 试试这种方法，希望这能帮助你解决问题。
