Question

我的listview项目有文本视图，图像视图和复选框。当我点击复选框我得到setonclick监听器的事件时，我需要删除带动画的已删除行。

所以，对于这个，如果我使用复选框视图，我只获得动画外观的复选框，而不是其他视图，如textview，imageview。

这是动画代码

 OnClickListener CheckboxListener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            CheckBox cb = (CheckBox) v ; 

             final Animation animation = AnimationUtils.loadAnimation(v.getContext(), R.anim.splashfadeout);
                v.startAnimation(animation);
                Handler handle = new Handler();
                handle.postDelayed(new Runnable() {

                    @Override
                    public void run() {
                        // TODO Auto-generated method stub
                       mcompletecallback.completePressedItem(cursorHelper.primaryKey);
                        notifyDataSetChanged();
                        animation.cancel();
                    }
                }, 1000);
}
}

在这个v是复选框视图，但我想知道隐藏的视图复选框，如果我在其上应用动画，它可以顺利运行。但我想知道如何在这里得到它？

这是我的动画xml代码

<?xml version="1.0" encoding="utf-8"?>

<scale
    android:duration="500"
    android:fromXScale="1.0"
    android:fromYScale="1.0"
    android:interpolator="@android:anim/linear_interpolator"
    android:toXScale="1.0"
    android:toYScale="0.0" />

我的适配器代码

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    String todayDate = Utilities.getTodayDate();
    String tomorrowDate = Utilities.getTomorrowDate();


    ViewHelper viewholder = null;
    DividerHelper dividerviewholder = null;


    int view = getItemViewType(position);

    if(view == TYPE_HEADER)
    {
        //perform header actions
    }
    else
    {
        //Cursor c = (Cursor) getItem(position-cursorPosition);

        Cursor c = (Cursor) getItem(position);

        if(convertView == null)
        {
            viewholder = new ViewHelper();

            convertView = mLayoutInflater.inflate(R.layout.layout_item, parent, false);

            viewholder.title = (TextView)convertView.findViewById(R.id.ID_item_title);
            viewholder.Notes = (TextView)convertView.findViewById(R.id.ID_item_notes);
            viewholder.Status = (CheckBox)convertView.findViewById(R.id.ID_item_is_completed_checkbox);
            convertView.setTag(viewholder);
            viewholder.Status.setTag(viewholder);
            viewholder.Status.setOnClickListener(completedCheckboxListener);

        }
        else
        {
            viewholder = (ViewHelper)convertView.getTag();

        }

        viewholder.primaryKey = c.getInt(0);
        viewholder.Notes = c.getString(9);
        viewholder.Title = c.getString(3);




    }

    return convertView;
}

Answer 1

在该列表视图上应用onItemClickListener，当您单击该行时，您将获得

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
    //here "view" is your complete row that you clicked where you can find your checkbox

}

感谢Sripathi & Navjot Bedi

我能够弄明白该怎么做，

我们需要调用View v1 = (View) cb.getParent();来获取复选框的父视图，然后

在V1对象上调用动画，

动画动画= AnimationUtils.loadAnimation（v1.getContext（），R.anim.splashfadeout）; CompleteUponCompletionofAnimation（animation，cursorHelper.key）; v1.startAnimation（动画）;

public void CompleteUponCompletionofAnimation(Animation fadeout, final int pk)
    {
        fadeout.setAnimationListener(new AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) { }
            @Override
            public void onAnimationRepeat(Animation animation) { }

            @Override
            public void onAnimationEnd(Animation animation) {
                //your change at end of animation
               notifyDataSetChanged();
            }
        });
    }

同样在convertview中，通过设置NULL

来删除动画

if(convertView == null)
{
}
else
{
if(convertView.getAnimation() != null)
convertView.setAnimation(null);
}
