将“Horizo​​ntalScrollView”添加到列表视图后，“setOnItemClickListener/setOnItemLongClickListener”不起作用

Question

我的“标准”列表视图的监听器工作得很好，但我想让单个列表视图项目水平滚动，这需要大量的试验和错误，但它终于奏效了。然而，这让我在聆听任何点击时变得敏感。我希望有一个简单的修复，比如添加另一个属性等。

这是我的听众（最小化）：

        listViewAllCards.setOnItemClickListener(new AdapterView.OnItemClickListener(){

            @Override
            public void onItemClick(AdapterView<?> parent, View viewClicked, int position, long id) {

                Log.i("LOG: (DP) SHORT","position " + position + " ID: " + id);

                switch (position) {

                // Training
                case 0:
                break;
              }
            }
        });

这是我的 xml：

    </HorizontalScrollView>

</RelativeLayout>

[编辑] 有趣的是，当我单击水平滚动区域时，它可以工作，因此滚动从列表视图项中窃取“焦点”可能是个问题：

[编辑] 我在类代码中添加了以下内容，OnItem 侦听器仍在“onCreate”sn-p 中（我希望这没问题）。我看到了这个射击，但对实际项目仍然没有敏感：

    private class CustomAllCardsAdapter extends ArrayAdapter<Flashcard> {

        public CustomAllCardsAdapter() {

            super(DatabasePage.this, R.layout.database_page_horizontal_list_view_item,allFlashcards);
        }

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

            View itemView = convertView;

            if (itemView == null) {

                itemView = getLayoutInflater().inflate(R.layout.database_page_horizontal_list_view_item, parent, false);
            }

            final HorizontalScrollView hScrollView = (HorizontalScrollView) itemView.findViewById(R.id.hScrollView);
            hScrollView.setOnTouchListener(new View.OnTouchListener() {

                @Override
                public boolean onTouch(View v, MotionEvent event) {

                    Log.i("DP: DEBUG", "HSCROLL" + event);

                    hScrollView.getParent().requestDisallowInterceptTouchEvent(true);

                    return false;
                }
            });

添加：

android:descendantFocusability="blocksDescendants"

到列表项的父布局..

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:descendantFocusability="blocksDescendants"   //add this
            android:background="@drawable/database_page_list_selector"
            android:orientation="horizontal"
            android:padding="5dp">

为scrollview 触摸事件添加requestDisallowInterceptTouchEvent(true);

scrollView1 = (ScrollView) findViewById(R.id.scrollview);
scrollView1.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        scrollView1.getParent().requestDisallowInterceptTouchEvent(true);
        return false;
    }
});
