我如何使用微调setOnItemLongClickListener [英] How can I use spinner setOnItemLongClickListener

问题描述

我试图使微调行为不同的方式，当用户点击一个项目很长一段时间。我有微调器的一些项目，我想两件事情。

1. 当用户简单的点击我想正常的项目中选择。
2. 当用户早就点击了一个项目我想显示对话框，包含编辑项选项，删除项目。

第一步工作得很好（ofcourse），但是当我试图做第二个任务，我不能作出微调产生longClicked事件。

下面是我的code：

  this.projectSpinner =（微调）this.findViewById（R.id.SpinnerProjects）;
    this.projectSpinner.setLongClickable（真正的）;

    this.projectSpinner.setOnItemLongClickListener（新AdapterView.OnItemLongClickListener（）{
        公共布尔onItemLongClick（适配器视图＆LT;＆GT;为arg0，
                                       查看ARG1，
                                       INT ARG2，
                                       长ARG3）{
            Toast.makeText（
                 AndroidTimeTrackerMainActivity.this，
                 长按，
                 Toast.LENGTH_SHORT）.show（）; //这敬酒不出来。
            返回false;
        }

    }）;
 

解决方案

在微调目前不支持 OnItemLongClickListener

I am trying to make the Spinner behave different way when the user clicked on an item for a long time. I have spinner with some project and I want two things.

1. When the user simple click on an item I want to normal select it.
2. When the user have long clicked on an item I want to show dialog, with options like "Edit item", "Delete item".

The first step works well (ofcourse), but when I am trying to do the second task I can not make spinner to generate longClicked event.

Here is my code:

    this.projectSpinner = (Spinner) this.findViewById(R.id.SpinnerProjects);
    this.projectSpinner.setLongClickable(true);

    this.projectSpinner.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener(){
        public boolean onItemLongClick(AdapterView<?> arg0, 
                                       View arg1, 
                                       int arg2, 
                                       long arg3) {
            Toast.makeText(
                 AndroidTimeTrackerMainActivity.this, 
                 "Long click", 
                 Toast.LENGTH_SHORT).show(); // This toast doesn't show up.
            return false;
        }

    });

解决方案

The Spinner currently does not support OnItemLongClickListener.
