Question

我正在尝试在listview行上实现onItemLongClickListener和onItemClickListener事件，但问题是当我longPress listview行并释放它时，两个事件同时被调用。实现这一目标的解决方案是什么。

这是我正在使用的代码。

listvideos.setLongClickable(true);

listvideos.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1,int pos, long arg3) {
        System.out.println("hh clickkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk");
        if( lastLoded == TIMELINE || lastLoded == UPLOADS){
            Intent i = new Intent(getActivity(), VideoStreamingActivity.class);
            i.putExtra("clipname", videosVo.getInnerTopVideosVos().get(pos).getClipName());
            i.putExtra("clipurl", videosVo.getInnerTopVideosVos().get(pos).getClipUrl());
            i.putExtra("uploadername", videosVo.getInnerTopVideosVos().get(pos).getUploader_name());
            i.putExtra("clipid", videosVo.getInnerTopVideosVos().get(pos).getClipId());
            i.putExtra("rating", videosVo.getInnerTopVideosVos().get(pos).getRating());
            i.putExtra("views", videosVo.getInnerTopVideosVos().get(pos).getTotalViews());
            i.putExtra("thumburl", videosVo.getInnerTopVideosVos().get(pos).getThumbUrl());
            adapterTopvideos.increaseViews(pos);
            startActivity(i);
        }
        else if(lastLoded == PROFILE){

            Intent i = new Intent(getActivity(), FriendProfileActivity.class);
            i.putExtra("friendid", videosVo.getInnerFriendsVos().get(pos).getId());
            i.putExtra("friendname", videosVo.getInnerFriendsVos().get(pos).getName());
            ApplicationConstants.bmpFriend = videosVo.getInnerFriendsVos().get(pos).getImage();
            startActivity(i);
        }
    }
});


listvideos.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
    @Override
    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
            int pos, long arg3) {
        System.out.println("hh longgggggggggggggggggggggggggggg click");
            // if(lastLoded == UPLOADS){
            //
            //     if(!videosVo.getInnerTopVideosVos().get(pos).isChecked())
            //         videosVo.getInnerTopVideosVos().get(pos).setChecked(true);
            //     else
            //         videosVo.getInnerTopVideosVos().get(pos).setChecked(false);
            //
            //     adapterTopvideos.notifyDataSetChanged();
            // }
        return false;
    }
});

试试这个;它会工作。我注意到你在listvideos.setOnItemLongClickListener中返回了false。而是返回true。

原因：执行onItemLongClick后返回true会阻止在onItemLongClick之后触发onItemClick事件。例如，

public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
    return true;
}

编辑：更改您的代码，如下所示。

您之前的代码：

listvideos.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

    @Override
    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
            int pos, long arg3) {
        System.out.println("hh longgggggggggggggggggggggggggggg click");

        // if(lastLoded == UPLOADS){
        //
        //     if(!videosVo.getInnerTopVideosVos().get(pos).isChecked())
        //         videosVo.getInnerTopVideosVos().get(pos).setChecked(true);
        //     else
        //         videosVo.getInnerTopVideosVos().get(pos).setChecked(false);
        //
        //     adapterTopvideos.notifyDataSetChanged();
        // }

        return false;
    }
});

将其更改为：

listvideos.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

    @Override
    public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
            int pos, long arg3) {
        System.out.println("hh longgggggggggggggggggggggggggggg click");

        // if(lastLoded == UPLOADS){
        //
        //     if(!videosVo.getInnerTopVideosVos().get(pos).isChecked())
        //         videosVo.getInnerTopVideosVos().get(pos).setChecked(true);
        //     else
        //         videosVo.getInnerTopVideosVos().get(pos).setChecked(false);
        //
        //     adapterTopvideos.notifyDataSetChanged();
        // }

        return true;
    }
});

我发现诀窍在于longclick侦听器回调的返回值。如果返回true，则在调用longclick后将不会调用onclick，并且只有在单击时才会调用simple click。请尝试这个，让我知道。

试试这个：

    // Item Click Listener for the listview
    OnItemLongClickListener itemClickListener = new OnItemLongClickListener() {

        @SuppressWarnings("unchecked")
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

            // TODO Auto-generated method stub
            HashMap<String, Object> item=(HashMap<String, Object>) arg0.getItemAtPosition(arg2);

            switch (arg2) {

                // Set event handler
                case 0:

                    break;

                case 1:

                    break;

                case 2:

                    break;

                ....
            }
        }
    };

    // Setting the item click listener for the listview
    listView.setOnItemLongClickListener(itemClickListener);
}

Answer 4

将listvideos.setOnItemLongClickListener()放在listvideos.setOnItemClickListener()之前。

这样，当您长按项目时，它将无法执行onItemClickListener()。

如何在Android上的listview行上实现onItemLongClickListener和onItemClickListener事件？
