Android 处理 View 重复点击的多种方法

1、抽象类

//实现 View.OnClickListener 接口
public abstract class OnThrottleClickListener implements View.OnClickListener {
 private static final String TAG = "OnThrottleClickListener";
 private static final int SKIP_DURATION = 300;//milliseconds
 private long mLastClickTime;
 @Override
 public void onClick(View v) {
   if (System.currentTimeMillis() - mLastClickTime > SKIP_DURATION) {
     onThrottleClick(v);
     mLastClickTime = System.currentTimeMillis();
   } else {
     Log.e(TAG, "OnThrottleClickListener: 重复点击");
   }
 }

protected abstract void onThrottleClick(View v);
}

//代替 new View.OnClickListener() 使用
id_tv_1.setOnClickListener(new OnThrottleClickListener() {
  @Override
  protected void onThrottleClick(View v) {
   Log.e(TAG, "onClick: OnThrottleClickListener ");
  }
});

2、代理模式

//代理类实现 View.OnClickListener 接口
public class ThrottleClickProxy implements View.OnClickListener {
 private static final String TAG = "ThrottleClickProxy";
 private static final int SKIP_DURATION = 300;//milliseconds
 private long mLastClickTime;
 //源对象
 private View.OnClickListener mOriginListener;
//构造
 public ThrottleClickProxy(View.OnClickListener mOriginListener) {
   this.mOriginListener = mOriginListener;
 }
 @Override
 public void onClick(View v) {
   if (System.currentTimeMillis() - mLastClickTime >= SKIP_DURATION) {
     mOriginListener.onClick(v);
     mLastClickTime = System.currentTimeMillis();
   } else {
     Log.e(TAG, "ThrottleClickProxy: 重复点击");
   }
 }
}

//使用
id_tv_2.setOnClickListener(new ThrottleClickProxy(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
       Log.e(TAG, "onClick: ThrottleClickProxy ");
    }
 }));

3、RxAndroid 之 RxBinding

implementation 'com.jakewharton.rxbinding3:rxbinding:3.0.0-alpha1'

RxView.clicks(id_tv_3)
   .throttleFirst(300, TimeUnit.MILLISECONDS)
   .subscribe(new Consumer<Unit>() {
    @Override
    public void accept(Unit unit) throws Exception {
      Log.e(TAG, "onClick: throttleFirst ");
    }
  });

4、AOP 之 Eclipse AspectJ

//采用 AspectJX 来快速配置 Eclipse AspectJ
//project
dependencies {
   classpath "com.android.tools.build:gradle:4.1.2"
   //add
   classpath 'com.hujiang.aspectjx:gradle-android-plugin-aspectjx:2.0.10'
}

plugins {
 id 'com.android.application'
 //add
 id 'android-aspectjx'
}
//module
dependencies {
 //add
 implementation 'org.aspectj:aspectjrt:1.9.5'
}

@Aspect
public class ThrottleClickAspect {
 private static final String TAG = "ThrottleClickAspect";
 private static final int SKIP_DURATION = 3000;
 private long mLastClickTime;

//所有的 android.view.View.OnClickListener.onClick 方法都会被织入，像第三方组件 RxView.clicks() 里也会
 @Around("execution(* android.view.View.OnClickListener.onClick(..))")
 public void aroundViewOnClick(ProceedingJoinPoint joinPoint) throws Throwable {
   if (System.currentTimeMillis() - mLastClickTime >= SKIP_DURATION) {
     joinPoint.proceed();
     mLastClickTime = System.currentTimeMillis();
   } else {
     Log.e(TAG, "ThrottleClickAspect: 重复点击");
   }
 }
}

代码无侵入方式，直接生效了
