Question

我使用ListView和自定义适配器。在此适配器中，我想使用HorizontalScrollView来连续显示完整信息。我得到了很长的文字所以我必须滚动。很遗憾，我的setOnItemClickListener无法识别点击它。如果删除horizontalScrollView，它可以工作。在过去的几个小时里，我在这里阅读了很多关于这个主题的内容，但没有什即使我的ListView也可以水平滚动，也可以接收事件吗？

    public void show_alert() {

    final Dialog dia = new Dialog(this);

    dia.setContentView(R.layout.alert);

    dia.setTitle(String.format(res.getString(R.string.msg_11)));
    dia.setCancelable(true);

    list_alert = (ListView) dia.findViewById(R.id.alert_list);

    list_alert.setAdapter(new MainActivityArrayAdapter(this, GetProtokollFileNames()));                                            

    this.list_alert.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> arg0, View arg1, int pos,
                long arg3) {

            Toast.makeText(MainActivity.this,
                    "Item in position " + pos + " clicked", Toast.LENGTH_LONG).show();              
            dia.dismiss();
        }
    });               
    dia.show();
}

类MainActivityArrayAdapter（...）使用rowlayout.xml。

public class MainActivityArrayAdapter extends ArrayAdapter<String> {
  private final Context context;

  private String[] Values;

  public MainActivityArrayAdapter(Context context, String[] values) {
    super(context, R.layout.rowlayout, values);
    this.context = context;    
    Values = values;
  }

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

      LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

      View rowView = inflater.inflate(R.layout.rowlayout, parent, false);


    return rowView;
  }
}

Answer 1

您可以实现自定义视图（horizontalScrollView）并覆盖某些方法：

@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
    boolean is_event = super.onInterceptTouchEvent(ev);
    if (is_event)
        getParent().requestDisallowInterceptTouchEvent(true);
    return ret;
}

@Override
public boolean onTouchEvent(MotionEvent ev) {
    boolean is_event = super.onTouchEvent(ev);
    if (is_event)
        getParent().requestDisallowInterceptTouchEvent(true);
    return ret;
}

Answer 2

此代码是您的问题的解决方案，您只需要为listView编写list_alert.setOnItemClickListener（...）和setClickable（true）

Dialog dialog = new Dialog(this);
dialog.setContentView(R.layout.dialog);
dialog.setTitle("Your Title");
dialog.setCancelable(true);
dialog.show();

list_alert = (ListView) dialog.findViewById(R.id.alert_list);
list_alert.setClickable(true);

list_alert.setAdapter(new MainActivityArrayAdapter(this, GetProtokollFileNames()));                                            

list_alert.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View arg1, int pos,
            long arg3) {

        Toast.makeText(MainActivity.this,
                "Item in position " + pos + " clicked", Toast.LENGTH_LONG).show();              
        dialog.dismiss();
    }
});
