Simple: inside the onClick, you need to disable the button:
简单：在 里面onClick，您需要禁用按钮：
yourButton.setEnabled(false);
So, when you retry to click it, nothing will happen, since the button is now disabled.
因此，当您重试单击它时，什么也不会发生，因为该按钮现在已禁用。
The comple code will be:
完整的代码将是：
yourButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
v.setEnabled(false);
// increment what you want, or other stuff..
}
});

you can add onclick handler like -
您可以添加 onclick 处理程序，例如 -
document.getElementById("buttonId").onclick = function() {
this.disabled = true; // it will disable your button
//do whatever your logic here or increment your value
}
or you can call function on onclick of button like -
或者您可以在单击按钮时调用函数，例如 -
function clickButton(){
getElementById("buttonId").disabled=true;
//do whatever your logic here or increment your value
}
