如果单击按钮则持续生成随机数，未单击时停止(Continously generating a random number if a button is clicked and stop when not clicked)

我想要在单击按钮时连续生成1到5之间的随机数字，并且在单击停止按钮时要停止此功能...

我应该做什么现在，使用Checked Change Listener上的这些切换按钮来实现此目的....

toggleButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { } });

I Want to generate a Random Numbers between 1 and 5 continously when button is clicked and want to stop this function when stop button is clicked...

What Should I Do Now with these toggle button on Checked Change Listener in order to achieve this....

toggleButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { } });

最满意答案

做这样的代码：

创建一个类级别的变量：

boolean is generating=false;

现在点击开始按钮：

startButton.setOnClickListener(..... onClick() { isGenerating=true; generateRandomNumber(); } });

现在点击停止按钮：

stopButton.setOnClickListener(..... onClick() { isGenerating=false; } });

创建方法：

public void generateRandomNumber () { while(isGenerating) { Random rand = new Random(); int n = rand.nextInt(5) + 1; //Here n is random number. } }

谢谢，快乐的编码。

Do code like this:

Create a class level variable:

boolean is generating=false;

Now on click of start button:

startButton.setOnClickListener(..... onClick() { isGenerating=true; generateRandomNumber(); } });

Now on click of stop button:

stopButton.setOnClickListener(..... onClick() { isGenerating=false; } });

Create a method:

public void generateRandomNumber () { while(isGenerating) { Random rand = new Random(); int n = rand.nextInt(5) + 1; //Here n is random number. } }

Thanks and happy coding.
