Android基于坐标对View进行模拟点击事件

private fun simulateTouchEvent(view: View, x: Float, y: Float) {
   val downTime = SystemClock.uptimeMillis()
   val eventTime = SystemClock.uptimeMillis() + 100
   val metaState = 0
   val motionEvent = MotionEvent.obtain(downTime, eventTime,
           MotionEvent.ACTION_DOWN, x, y, metaState)

   view.dispatchTouchEvent(motionEvent)

   val upEvent = MotionEvent.obtain(downTime + 1000, eventTime + 1000,
           MotionEvent.ACTION_UP, x,y, metaState)
   view.dispatchTouchEvent(upEvent)
}

webview?.setOnTouchListener { v, event ->
   debugMessage("onTouchListener x=${event.x};y=${event.y}")
   false
}

webview?.webViewClient = object : WebViewClient() {
   override fun onPageFinished(view: WebView?, url: String?) {
       super.onPageFinished(view, url)
       webview?.post {
           webview?.let {
               simulateTouchEvent(it, it.width / 2f, it.height / 2f)
           }
       }
   }
}
