【问题描述】：

我已经为双击创建了一个 Java 类，但我无法双击该项目，因为当我只单击一次时，该项目不会等待双击！

双击类代码

package com.programiner.studyvillaadmin.Classes.Listener;

import android.view.View;

public abstract class DoubleClickListener implements View.OnClickListener 

    private static final long DOUBLE_CLICK_TIME_DELTA = 300;//milliseconds

    long lastClickTime = 0;

    @Override
    public void onClick(View v) 
        long clickTime = System.currentTimeMillis();
        if (clickTime - lastClickTime < DOUBLE_CLICK_TIME_DELTA)
            onDoubleClick(v);
            lastClickTime = 0;
         else 
            onSingleClick(v);
        
        lastClickTime = clickTime;
    

    public abstract void onSingleClick(View v);
    public abstract void onDoubleClick(View v);

【参考方案1】：

private long mLastClickTime = 0;
    @Override
    public void onClick(View v) 
        if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) //*1000 is time to perform second click*
            return; *// return when second click happen in second*
        mLastClickTime = SystemClock.elapsedRealtime();
        GameSound.getInstance(getApplicationContext()).sound__(GameSound.buttonClick);

        if (v == findViewById(R.id.tvUsername)) 
            StartActivity(UserProfile.class);
        
    

示例

public long mLastClickTime = 0; //声明和定义public

holder.itemView.setOnClickListener(new View.OnClickListener()   //click lister of itemview of RV Adapter
                            @Override
                            public void onClick(View v) 
                                if (SystemClock.elapsedRealtime() - mLastClickTime < 1000) //*1000 is time to perform second click*
                                    return; // return when second click happen in second*
                                mLastClickTime = SystemClock.elapsedRealtime();

                                //do stuff here...
                            
                        );

作为初学者！你能不能把你答案的全部代码提供给我，并展示如何在 RV 适配器中实现这个类

好的，请检查我编辑的答案。
