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

Question

我试图在listview行上实现onItemLongClickListener和onItemClickListener事件,但问题是当我longPress列表视图行并释放它时,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.我注意到你回来了listvideos.setOnItemLongClickListener.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.

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 后不会调用 onclick，而 simple click 仅在单击时调用。请尝试这个并让我知道。
