expandable textview in listview

How to reset the collapse-state in a listview?
When listview scrolling up and down, the reused textview's height display not right.

I didn't originally intend this to be used within a ListView where the view gets recycled.
However, I believe you could try the following method to reset the collapsed state within your ListView.
(I never tested it, so it might not work.)

Reset the ExpandableTextView's height to its original value within your getView() method inside your adapter, then call setText() and requestLayout().

I also use it in listview, I solved this problem, maybe it have some bugs.

1. first add two members:

   // when in listview , use this map to save collapsed status
   private SparseArrayCompat mConvertTextCollapsedStatus = new SparseArrayCompat();
   private int mPosition;

2. add a method:

      public void setConvertText(int position,String text) {
   boolean isCollapsed = mConvertTextCollapsedStatus.get(position, true);
   mPosition = position;
   clearAnimation();
   mCollapsed = isCollapsed;
   if (mButton != null) {
       mButton.setImageDrawable(mCollapsed ? mExpandDrawable : mCollapseDrawable);
   }
   clearAnimation();
   if (mCollapsed) {
       if (mTv!=null){
           mTv.setMaxLines(mMaxCollapsedLines);
       }
   } else {
       if (mTv!=null) {
           mTv.setMaxLines(Integer.MAX_VALUE);
       }
   }
   this.getLayoutParams().height = android.view.ViewGroup.LayoutParams.WRAP_CONTENT;
   setText(text);
   requestLayout();
   

   }

3. in onClick Method, add

   mCollapsed = !mCollapsed;
   mConvertTextCollapsedStatus.put(mPosition, mCollapsed);
   

I have test it , it works in listview.

I will commit it to github next time
