2、Android点击防抖

1、拦截

• FastClickUtil.java ``` package com.toycloud.androiddemo;

import android.util.Log;

/**

• Description: 防止点击事件过快
• Author: wangchun
• Date: 2020/9/30
• Time: 9:43 AM */

public class FastClickUtil {

private static final String TAG = "FastClickUtil";
/**
 * 两次点击的时间间隔
 */
private static final int MIN_CLICK_DELAY_TIME = 500;
/**
 * 上次点击的时间戳
 */
private static long mLastClickTime;
public static boolean isClickFast() {
    return isClickFast(MIN_CLICK_DELAY_TIME);
}
public static boolean isClickFast(int clickTime) {
    long cur = System.currentTimeMillis();
    if (cur > mLastClickTime && cur - mLastClickTime < clickTime) {
        Log.d(TAG, "isClickFast: true");
        return true;
    } else {
        mLastClickTime = cur;
        return false;
    }
}

}

- 用法

view.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (FastClickUtil.isClickFast()){ return; } } });

## 2、自定义Listener
- FastClickListener.java

package com.toycloud.androiddemo;

import android.util.Log; import android.view.View;

/**

• Description: 防止点击过快
• Author: wangchun
• Date: 2020/9/30
• Time: 9:58 AM */

public abstract class FastClickListener implements View.OnClickListener {

private static final String TAG = "FastClickListener";
/**
 * 两次点击的时间间隔
 */
private static final int MIN_CLICK_DELAY_TIME = 500;
/**
 * 上次点击的时间戳
 */
private static long mLastClickTime;
@Override
public void onClick(View view) {
    long currentTime = System.currentTimeMillis();
    if (currentTime - mLastClickTime > MIN_CLICK_DELAY_TIME) {
        mLastClickTime = currentTime;
        onFastClickListener(view);
    } else {
        Log.d(TAG, "click fast");
    }
}
public abstract void onFastClickListener(View view);

}

- 用法

view.setOnClickListener(new FastClickListener() { @Override public void onFastClickListener(View view) { Log.e(TAG, “onFastClickListener: “ ); } }); ```
