我试图用Flip animation
显示我的每个listview
项目的正面和背面。动画效果很好,但动画的结果也被应用于其他项目。而且,当我上下滚动时,我的物品的位置会改变。我的代码如下:Android中的翻转动画Listview项目
public View getView(final int position, final View convertView, ViewGroup parent) {
ArtItemHolder holder;
View view = convertView;
if (view == null) {
LayoutInflater inflater = ((Activity) this.context).getLayoutInflater();
holder = new ArtItemHolder();
view = inflater.inflate(R.layout.feed_list_item, parent, false);
holder.image = (ImageView) view.findViewById(R.id.img_Image);
holder.pubDate = (TextView) view.findViewById(R.id.txt_puslishDate);
holder.arTitle = (TextView) view.findViewById(R.id.txt_arTitle);
holder.commentCount = (TextView) view.findViewById(R.id.txt_commentCount);
holder.rotator = (ImageView) view.findViewById(R.id.card_roretor);
holder.cardFace = view.findViewById(R.id.card_face);// first of 2 child parent layout of feed_list_item.xml
holder.cardBack = view.findViewById(R.id.card_back);// second of 2 child parent layout of feed_list_item.xml
view.setTag(holder);
} else {
holder = (AdvItemHolder) view.getTag();
}
holder.rotator.setOnClickListener(new MyFlipperListener(view, holder.cardFace, holder.cardBack));
return view;
}
private class MyFlipperListener implements OnClickListener{
View parent, frontFace, backFace;
public MyFlipperListener(View parent, View frontFace, View backFace) {
this.parent = parent;
this.frontFace = frontFace;
this.backFace = backFace;
}
public void onClick(View v) {
FlipAnimation flipAnimation = new FlipAnimation(frontFace, backFace);
if (frontFace.getVisibility() == View.GONE)
{
flipAnimation.reverse();
}
parent.startAnimation(flipAnimation);
}
}
private static class ArtItemHolder{
ImageView image;
TextView pubDate;
TextView arTitle;
TextView commentCount;
ImageView rotator;
View cardFace, cardBack;
}
我在列表视图项目布局XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<LinearLayout
android:id="@+id/card_face"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@drawable/feed_item_selector"
android:layout_margin="8dip"
android:padding="2dip">
########## MAIN CONTENT HERE ###########
</LinearLayout>
<LinearLayout
android:id="@+id/card_back"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:padding="2dip"
android:visibility="gone">

</LinearLayout>
UPDATE
FlipAnimation flipAnimation = new FlipAnimation(holder.cardFace, holder.cardBack);
holder.rotator.setOnClickListener(new MyFlipperListener(view, holder.cardFace, flipAnimation));
private class MyFlipperListener implements OnClickListener{
View parent, frontFace;
FlipAnimation flipAnimation;
public MyFlipperListener(View parent, View frontFace, FlipAnimation flip) {
this.parent = parent;
this.frontFace = frontFace;
this.flipAnimation = flip;
}
public void onClick(View v) {
if (frontFace.getVisibility() == View.GONE){
flipAnimation.reverse();
}
parent.startAnimation(flipAnimation);
}
}
试试这个改变你的构造函数'公共MyFlipperListener(查看父,查看frontFace,FlipAnimation flipAnimation)'所以你知道该怎么做还是怎么做呢,如果这是你的构造的样子..并instatiate你的flipanimation中,如果视图是空的子句..意思把flipanimation在artitemholder ..我的建议可能是伟大的或狗屎..只是尝试它..让我知道 – Elltz
@Elltz结果是一样的。更新我的问题只是为了向你展示我做了什么。 – eskimoo
好的,让我问你几个问题,然后我发布一个答案,你是翻转整个项目视图?或只是holder.rotator这是imageview?其次,我按了你正在捕捉的ImageView的onclicklistener权利? – Elltz
