Android 处理 View 重复点击的多种方法

//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//projectdependencies { 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’}//moduledependencies { //add implementation ’org.aspectj:aspectjrt:1.9.5’}

@Aspectpublic 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
