如果按钮做的唯一一件事是启动一个新活动，这个问题可以通过“singleTop”活动启动模式和在意图上设置FLAG_ACTIVITY_CLEAR_TOP来解决。这种方法不适用于复杂活动的层次结构，但适用于简单的树状应用程序结构。

对我来说，只有记住时间戳并检查它(距离上次点击超过1秒)才有帮助。

扩展的Kotlin方法:

fun View.setOneTimeClickListener(delayMillis: Long = 1000, block: () -> Unit) {
    setOnClickListener {
        this.isEnabled = false
        block()
        postDelayed({ isEnabled = true }, delayMillis)
    }

在代码中的用法:

someView.setOneTimeClickListener { someFun() }

delayMillis参数可用于设置按钮将被禁用的时间。

someView.setOneTimeClickListener(500) { someFun() }

    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            //to prevent double click
            button.setOnClickListener(null);
        }
    });

如果你在onClick()中进行计算密集型工作，则禁用按钮或设置不可点击是不够的，因为单击事件可以在禁用按钮之前排队。我写了一个实现OnClickListener的抽象基类，你可以重写，通过忽略任何排队点击来修复这个问题:

/** 
 * This class allows a single click and prevents multiple clicks on
 * the same button in rapid succession. Setting unclickable is not enough
 * because click events may still be queued up.
 * 
 * Override onOneClick() to handle single clicks. Call reset() when you want to
 * accept another click.
 */
public abstract class OnOneOffClickListener implements OnClickListener {
    private boolean clickable = true;

    /**
     * Override onOneClick() instead.
     */
    @Override
    public final void onClick(View v) {
        if (clickable) {
            clickable = false;
            onOneClick(v);
            //reset(); // uncomment this line to reset automatically
        }
    }

    /**
     * Override this function to handle clicks.
     * reset() must be called after each click for this function to be called
     * again.
     * @param v
     */
    public abstract void onOneClick(View v);

    /**
     * Allows another click.
     */
    public void reset() {
        clickable = true;
    }
}

用法与OnClickListener相同，但重写OnOneClick()代替:

OnOneOffClickListener clickListener = new OnOneOffClickListener() {
    @Override
    public void onOneClick(View v) {

        // Do stuff

        this.reset(); // or you can reset somewhere else with clickListener.reset();
    }
};
myButton.setOnClickListener(clickListener);

具有Kotlin扩展功能:

fun View.onSingleClick(action: (v: View) -> Unit) {
    setOnClickListener(object : View.OnClickListener {
        override fun onClick(v: View) {
            isClickable = false
            action(v)
            postDelayed({ isClickable = true }, 700)
        }
    })
}

用法:

button.onSingleClick { myAction() }
