我在一个活动中有一个ListView.在每个列表项中都有一个文本和一个CheckBox.单击CheckBox,我想从ListView中删除该项目,并希望添加一个动画,如向下滑动或淡出,然后删除.
有帮助吗？
解决方法
看看我的回答
protected void removeListItem(View rowView,final int positon) {
// TODO Auto-generated method stub
final Animation animation = AnimationUtils.loadAnimation(rowView.getContext(),R.anim.splashfadeout);
rowView.startAnimation(animation);
Handler handle = new Handler();
handle.postDelayed(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
array.remove(positon);
adapter.notifyDataSetChanged();
animation.cancel();
}
},1000);
}
在onView中单击ListView调用removeListItem(查看rowView,final int positon)方法
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView <? > parent,View rowView,int positon,long id) {
// TODO Auto-generated method stub
Toast.makeText(rowView.getContext(),"" + positon,Toast.LENGTH_LONG).show();
removeListItem(rowView,positon);
}
});
和res / anim / splashfadeout.xml
<?xml version="1.0" encoding="utf-8" ?> <alpha xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/decelerate_interpolator" android:zAdjustment="top" android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="2000" />
