Java 将进度条与方法的执行相关联
如何将进度条的进度与我知道执行时间的方法的执行联系起来? 这是我的控制器类的代码Java 将进度条与方法的执行相关联,java,javafx,progress-bar,Java,Javafx,Progress Bar,如何将进度条的进度与我知道执行时间的方法的执行联系起来? 这是我的控制器类的代码 @FXML void elaboraVideo(ActionEvent event) throws IOException { if(control == false) { Alert alert = new Alert(AlertType.INFORMATION); alert.setTitle("Impossibile proseguire"); al
@FXML
void elaboraVideo(ActionEvent event) throws IOException {
if(control == false) {
Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Impossibile proseguire");
alert.setHeaderText(null);
alert.setContentText("Nessun video selezionato!");
alert.show();
} else {
long inizio = System.currentTimeMillis();
videoM.workVideo(absolutePath);
long fine = System.currentTimeMillis();
long time=(inizio-fine)/1000;
load.setProgress(time);
}
}
该方法是workVideo,它位于另一个类中
这是workVideo的代码,它可以正常工作

这里不太清楚您的意思。在方法实际完成之前,您不知道该方法的执行时间,因此您不能真正希望在它执行时使进度条前进。还是我误解了你的意图?除非你有办法知道,否则我想把进度条推进到执行方法的末尾
