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 ");
   }
});

//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 ");
     }
  }));

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 ");
     }
   });

  //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(..))")
