使用Android龙钮preSS递增/递减计数器 [英] Using an Android Long-Button press to increment/decrement counter

问题描述

我希望能够以preSS一个按钮在我的计划，并保持一段时间（不释放），以增加一个变量。问题我有现在的问题是，当我进行它只能运行一次漫长的按钮preSS，直到我再次释放和preSS。

首先，我想看看是否有办法做到这一点，而不必使用OnTouchListener，只是使用OnLongClick。有没有一种方法来检查按钮的价值？例如..的buttonDown = TRUE;进行一次whileloop递增，直到松开按钮。

其次，我不想被延迟了更新，因为增加的值被绘制为用户按住按钮

基本上我做这样的事情：

  btn_resume.setOnLongClickListener（新OnLongClickListener（）{
公共布尔onLongClick（视图v）{


.. code ..
返回true;

        }
    }）;
 

解决方案

如果我理解你的问题正确的这样一个使用OnLongClickListener来实现。

I want to be able to press a button on my program and hold it down (without releasing) to increment a variable. Problem I am having right now is when I conduct the long button press it only runs once, until I release and press again.

First I want to find out if there is a way to do this without having to use the OnTouchListener, and just using the OnLongClick. Is there a way to check the value of the button? For example.. buttondown=true; Conduct a whileloop to increment until the button is released.

Second, I don't want the updates to be delayed, because the incremented value is being drawn as the user holds down the button.

Basically I am doing something like this:

btn_resume.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(View v) {


..code..
return true;

        }
    });

解决方案

If I understood your question correct this can be achieved using a OnLongClickListener.
