下面是一个OnClickListener代理，它可以根据qezt的答案阻止连续的单击。

import android.os.SystemClock;
import android.view.View;

public class MultiClickGuard implements View.OnClickListener {    

    private long mLastClickTime;

    private final int mThresholdMillis;
    private final View.OnClickListener mListener;

    public MultiClickGuard(View.OnClickListener listener, int thresholdMillis) {
        if (listener == null) {
            throw new NullPointerException("Null OnClickListener");
        }
        if (thresholdMillis < 0) {
            throw new IllegalArgumentException("Negative click threshold: " + thresholdMillis);
        }

        mListener = listener;
        mThresholdMillis = thresholdMillis;
    }

    @Override
    public void onClick(View v) {
        // Using a time threshold to prevent successive clicks.
        if (SystemClock.elapsedRealtime() - mLastClickTime < mThresholdMillis) {
            return;
        }
        mLastClickTime = SystemClock.elapsedRealtime();

        // Forward the click event to the *real* listener.
        mListener.onClick(v);
    }
}

用法示例

button.setOnClickListener(new MultiClickGuard(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // do something
    }
}, 1000));

button.setOnClickListener(new MultiClickGuard(v -> {...}, 1000));
button.setOnClickListener(new MultiClickGuard(v -> doSomething(), 1000));

在试图阻止启动一个活动的多个实例的情况下，考虑指定启动模式:理解任务和返回堆栈，这是可靠的方式。

如果您试图阻止打开一个对话框片段的多个实例，您可以检查片段管理器是否已经包含了对话框，例如getSupportFragmentManager(). findfragmentbytag (tag)。

Kotlin创建类SafeClickListener

class SafeClickListener(
        private var defaultInterval: Int = 1000,
        private val onSafeCLick: (View) -> Unit
) : View.OnClickListener {
    private var lastTimeClicked: Long = 0    override fun onClick(v: View) {
        if (SystemClock.elapsedRealtime() - lastTimeClicked < defaultInterval) {
            return
        }
        lastTimeClicked = SystemClock.elapsedRealtime()
        onSafeCLick(v)
    }
}

在baseClass或else中创建一个函数

fun View.setSafeOnClickListener(onSafeClick: (View) -> Unit) {val safeClickListener = SafeClickListener {
        onSafeClick(it)
    }
    setOnClickListener(safeClickListener)
}

并使用按钮点击

btnSubmit.setSafeOnClickListener {
    showSettingsScreen()
}

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。

只有2步，你可以在你的应用程序的任何地方使用它。

步骤1。创建一个单例管理器[避免多次点击]

package com.im.av.mediator;

import android.os.SystemClock;

import java.util.HashMap;

/**
 * Created by ShuHeng on 16/6/1.
 */
public class ClickManager {



    private HashMap<Integer,Long> laskClickTimeMap=new HashMap<Integer,Long>();
    public volatile static ClickManager mInstance =null;

    public static ClickManager getInstance(){
        if (mInstance == null) {
            synchronized(ClickManager.class) {
                if (mInstance == null) {
                    mInstance = new ClickManager();
                }
            }
        }
        return mInstance;
    }
   public boolean isClickable1s(Integer key){
       Long keyLong = laskClickTimeMap.get(key);
       if(keyLong==null){
           laskClickTimeMap.put(key,SystemClock.elapsedRealtime());
           return true;
       }else{
           if (SystemClock.elapsedRealtime() - keyLong.longValue() < 1000){
               return false;
           }else{
               laskClickTimeMap.put(key,new Long(SystemClock.elapsedRealtime()));
               return true;
           }
       }
   }
}  

步骤2。添加一行，避免多次单击。

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int id = v.getId();
    if (id == R.id.iv_back) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_back))return;
        //do something
    } else if (id == R.id.iv_light) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_light))return;
        //do something
    } else if (id == R.id.iv_camerarotate) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_camerarotate))return;
           //do something
    } else if (id == R.id.btn_delete_last_clip) {
        if(!ClickManager.getInstance().isClickable1s(R.id.btn_delete_last_clip))return;
          //do something

    } else if (id == R.id.iv_ok) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_ok))return;
        //do something
    }
}

对于任何使用数据绑定的用户:

@BindingAdapter("onClickWithDebounce")
fun onClickWithDebounce(view: View, listener: android.view.View.OnClickListener) {
    view.setClickWithDebounce {
        listener.onClick(view)
    }
}

object LastClickTimeSingleton {
    var lastClickTime: Long = 0
}

fun View.setClickWithDebounce(action: () -> Unit) {
    setOnClickListener(object : View.OnClickListener {

        override fun onClick(v: View) {
            if (SystemClock.elapsedRealtime() - LastClickTimeSingleton.lastClickTime < 500L) return
            else action()
            LastClickTimeSingleton.lastClickTime = SystemClock.elapsedRealtime()
        }
    })
}



<androidx.appcompat.widget.AppCompatButton
                    ..
  android:text="@string/signup_signin"
  app:onClickWithDebounce="@{() -> viewModel.onSignUpClicked()}"
                   ... />

当UI线程阻塞时，单击事件队列。对于按钮单击事件，请尽快将其更改为后台任务，以避免单击事件在彼此后面排队。

在activity类中声明一个volatile boolean或lock:

private volatile boolean saving = false;

创建一个onClickListener按钮，通过保存和启动一个后台任务来完成工作:

saveButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View view) {
        if (!saving) {
            saving = true;
            new SaveAsyncTask().execute();
        }
    }
});

创建一个内部的SaveAsyncTask类来在后台完成工作:

class SaveAsyncTask extends AsyncTask {

    @Override
    protected Object doInBackground(Object[] objects) {
        // Do something here, simulate a 3 second task
        SystemClock.sleep(3000);
        saving = false;
        return null;
    }
}
