try this way, first declare global variable on your activity class file like below :
尝试这种方式，首先在您的活动类文件上声明全局变量，如下所示：
int clickcount=0;
after add click event to button and increment value clickcount variable like below code:
将单击事件添加到按钮并增加值 clickcount 变量后，如下代码所示：
yourbutton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
clickcount=clickcount+1;
if(clickcount==1)
{
//first time clicked to do this
Toast.makeText(getApplicationContext(),"Button clicked first time!", Toast.LENGTH_LONG).show();
}
else
{
//check how many times clicked and so on
Toast.makeText(getApplicationContext(),"Button clicked count is"+clickcount, Toast.LENGTH_LONG).show();
}
}
});

you can add clicks into List<Long/*timestamp*/>and read values later, you can store your clicks into list and cleanup this list by timer. you can... you have many ways to do this. and save values into your database or preferences, if you need.
您可以List<Long/*timestamp*/>稍后添加点击并读取值，您可以将点击存储到列表中并通过计时器清理此列表。你可以......你有很多方法可以做到这一点。并根据需要将值保存到您的数据库或首选项中。

The answer given by @sandipon is fine.But global variables could be destroyed,you can use SharedPreferences to store the value in case you'd like to make it persistent.
@sandipon 给出的答案很好。但是全局变量可能会被破坏，如果您想让它持久化，您可以使用 SharedPreferences 来存储该值。
