可以在任何解决我的问题..在斗争的最后2天之后我得到了总产量的70％清晰。 EXP：我有列表视图数据从server..Inside列表视图来有一些文本，按钮，滚动索引A，BC，d，E，F，G。
问题：按钮不工作时，我就点击它来......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是示出了正确的方式和工作很好..

在点击这个按钮的情况下工作正常，但的滚动视图A，B，C也工作正常，但在侧面不会有字母A，B，C，d，E，F，G ......如果我添加列表视图中homempleb.xml，那么这两个将正常工作，但没有字母索引和所示图像中。 我想这两个按钮和滚动索引工作像上面图片..我不会在这个主题很好。 plz帮助我就说明了这种方式：

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由索引滚动捕获。 见https://github.com/denley/IndexableListView/commit/18210a54487ba079bb332fafec709e2de26883db

只要改变这几行字，你会好的。

编辑：我刚刚签出的好奇心。 这个链接是死了。 我猜的错误是最新版本（检查出解决原IndexableListView项目最近被更新）。 我不知道是什么的变化是，甚至是什么问题了，所以这里是恕我直言，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 

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;
}
