SingleClick：
@Retention(AnnotationRetention.RUNTIME)
@Target(AnnotationTarget.FUNCTION)
annotation class SingleClick(
// 点击间隔时间，毫秒
val value: Long = 500
)
SingleClickAspect：
import android.os.SystemClock
import org.aspectj.lang.ProceedingJoinPoint
import org.aspectj.lang.annotation.Around
import org.aspectj.lang.annotation.Aspect
import org.aspectj.lang.annotation.Pointcut
import org.aspectj.lang.reflect.MethodSignature
@Aspect
class SingleClickAspect {
@Pointcut("execution(@你的包名.SingleClick * *(..))")
fun methodAnnotated() { }
@Around("methodAnnotated()")
@Throws(Throwable::class)
fun aroundJoinPoint(joinPoint: ProceedingJoinPoint) {
try {
// 取出方法的注解
val signature = joinPoint.signature as MethodSignature
val method = signature.method
// 检查方法是否有注解
val hasAnnotation = method != null && method.isAnnotationPresent(SingleClick::class.java)
if (hasAnnotation) {
// 计算点击间隔，没有注解默认500，有注解按注解参数来，注解参数为空默认500；
val singleClick = method.getAnnotation(SingleClick::class.java)
val interval = singleClick.value
// 检测间隔时间是否达到预设时间并且线程空闲
if (canClick(interval)) {
joinPoint.proceed()
}
} else {
joinPoint.proceed()
}
} catch (e: Exception) {
// 出现异常不拦截点击事件
joinPoint.proceed()
}
}
// 判断是否响应点击
private fun canClick(interval: Long): Boolean {
val time = SystemClock.elapsedRealtime()
val timeInterval = Math.abs(time - mLastClickTime)
if (timeInterval > interval) {
mLastClickTime = time
return true
}
return false
}
companion object {
// 最后一次点击的时间
private var mLastClickTime: Long = 0
}
}
build.gradle(项目)：
buildscript {
dependencies {
classpath 'com.hujiang.aspectjx:gradle-android-plugin-aspectjx:2.0.4'
}
}
build.gradle(APP)：
plugins {
id 'android-aspectjx'
}
使用：
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

</androidx.constraintlayout.widget.ConstraintLayout>
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
@SingleClick(800)
fun onTextClick(view: View) {

}
