按钮在列表视图适配器

Question

任何可以解决我的问题..最后经过2天的斗争，我清楚地得到了70％的输出。经验：我有listview哪些数据来自服务器..内部Listview有一些文本，按钮和滚动索引A，BC，D，E，F，G。
问题：按钮不工作意味着当我点击它时...如果添加下面的代码。 其寻找一些以下图片是什么：

在这里，我曾使用XML以这种方式---> com.woozzu.android.widget.IndexableListView 在本案例按钮ONCLICK工作不滚动视图A，B，C为表示正确的方式和工作很好..

在这种情况下点击按钮工作正常，但滚动视图A，B，C也工作正常，但在一边将不会有字母A，B，C，D，E，F，G ... 如果我ADD在homempleb.xml中的列表视图，那么这两个都将工作得很好，但没有像在图像中显示的字母索引。我希望按钮和滚动索引像上面的图像一样工作..我不擅长这个话题。 plz帮助我 它显示了这种方式：

homempleb.xml

<LinearLayout 
     android:id="@+id/scrollView1" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:layout_alignParentLeft="true" 
     android:background="#335552" 
     android:layout_below="@+id/relativeLayout4" >      
    <ListView 
      android:id="@+id/homelistView" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"    
      android:layout_weight="1.04" 
      android:dividerHeight="0dip" /> 

Answer 1

如果有人还在关心：

使用TouchEvent由索引滚动逮住。 请参阅https://github.com/denley/IndexableListView/commit/18210a54487ba079bb332fafec709e2de26883db

只要改变那几行就可以了。

编辑：我刚刚出于好奇。链接已经死亡。我猜这个错误是在最近的版本中解决的（请查看最近更新的original IndexableListView project）。我不知道是什么的变化是，甚至问题是了，所以在这里什么是恕我直言，本来是负责的问题，以防万一我的工作职能：

IndexedListView.java

@Override 
public boolean onTouchEvent(MotionEvent ev) { 
    if (mScroller != null && mScroller.onTouchEvent(ev)) 
     return true; 
    try{ 
    if (mGestureDetector == null) { 
     mGestureDetector = new GestureDetector(getContext(), 

       new GestureDetector.SimpleOnGestureListener() { 
        @Override 
        public boolean onFling(MotionEvent e1, MotionEvent e2, 
          float velocityX, float velocityY) { 
         if(mScroller!=null){ 
         mScroller.show(); 
         } 
         return super.onFling(e1, e2, velocityX, velocityY); 
        } 

       }); 

    } 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
    mGestureDetector.onTouchEvent(ev); 

    return super.onTouchEvent(ev); 
} 

@Override 
public boolean onInterceptTouchEvent(MotionEvent ev) { 
    if(mScroller!=null){ 
    if(mScroller.contains(ev.getX(), ev.getY())){ 
     return true; 
    } 

    return super.onInterceptTouchEvent(ev); 
    } 
    return false; 
} 

IndexedScroller。java的

public boolean onTouchEvent(MotionEvent ev) { 
    switch (ev.getAction()) { 
    case MotionEvent.ACTION_DOWN: 
     if (mState != STATE_HIDDEN && contains(ev.getX(), ev.getY())) { 
      setState(STATE_SHOWN); 
      mIsIndexing = true; 

      mCurrentSection = getSectionByPoint(ev.getY()); 

      mListView.setSelection(mIndexer 
        .getPositionForSection(mCurrentSection)); 
      return true; 
     } 
     break; 
    case MotionEvent.ACTION_MOVE: 
     if (mIsIndexing) { 

      if (contains(ev.getX(), ev.getY())) { 

       mCurrentSection = getSectionByPoint(ev.getY()); 
       mListView.setSelection(mIndexer 
         .getPositionForSection(mCurrentSection)); 
      } 
      return true; 
     } 
     break; 
    case MotionEvent.ACTION_UP: 
     if (mIsIndexing) { 
      mIsIndexing = false; 
      mCurrentSection = -1; 
     } 
     if (mState == STATE_SHOWN) 
      setState(STATE_HIDING); 
     break; 
    } 
    return false; 
}
