任何人都可以解决我的问题.. 经过 2 天的努力，我终于得到了 70% 的输出。 Exp：我有列表视图，其数据来自服务器。列表视图内部有一些文本、按钮和滚动索引 A、BC、D、E、F、G。
问题：按钮不起作用意味着当我单击它时...如果添加以下代码。
它看起来有些像下面的图片：
我在这里以这种方式在 XML 中使用---> com.woozzu.android.widget.IndexableListView 在这种情况下，单击按钮不起作用，滚动视图 A、B、C 以正确的方式显示并且工作正常。

在这种情况下，单击按钮工作正常，但滚动视图 A、B、C 也工作正常，但在侧面不会有字母 A、B、C、D、E、F、G... 如果我在 homempleb.xml 中添加 listview，那么两者都可以正常工作，但没有像图像中所示的字母索引。我希望按钮和滚动索引都像上面的图片一样工作。我不擅长这个主题。请帮助我 它是这样显示的：
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" />
如果有人仍然关心：
The TouchEvent is catched by the index scroller.
See https://github.com/denley/IndexableListView/commit/18210a54487ba079bb332fafec709e2de26883db
只要改变那几行就可以了。
编辑：我只是出于好奇而查看。链接已失效。我猜这个错误在最近的版本中已经解决了（查看原始 IndexableListView 项目最近更新）。我不知道发生了什么变化，甚至不知道问题是什么，所以这是我的工作职能，恕我直言，可能是导致问题的原因，以防万一：
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);
}

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