很简单:Java的如何使用" isRunning"在音频剪辑? [英] Simple: Java how to use "isRunning" on an audio clip?
问题描述
在java中我需要检查是否有音频剪辑运行,但是当我尝试这样的:
如果(clip1.isRunning()){}
Eclipse中给我的错误:
的方法isRunning()是未定义的类型音频剪辑。
我要补充的东西上的音频剪辑使用isRunning()?还是我做错了什么?
由于它是一个长的节目在这里只是我的进口,我初始化音频剪辑和部分在那里我使用它:
进口java.applet.Applet中;
进口java.applet.AudioClip中;
进口java.awt.Color中;
进口java.awt.Font中;
进口java.awt.Graphics;
进口java.awt.Image中;
进口java.awt.Toolkit中;
进口java.awt.event.ActionEvent中;
进口java.awt.event.ActionListener;
进口java.awt.event.KeyEvent中;
进口java.awt.event.KeyListener;
进口java.awt.event.MouseEvent中;
进口java.awt.event.MouseListener;
进口了java.util.Random;
javax.sound.sampled.Clip中的进口;
进口javax.swing.Timer中;音频剪辑clip1;公共无效鼠标pressed(我的MouseEvent){
如果(XPOS大于0&放大器;&放大器; XPOS℃,+ 64&放大器;&放大器; yPos大于0&放大器;&放大器;
yPos< 0 + 64){
如果(soundMuted == FALSE){
soundMuted = TRUE;
clip1.stop();
}
其他{
如果(clip1.isRunning()){ }
其他{
soundMuted = FALSE;
clip1.play();
}
} }
}
和以下是错误我得到:

java.applet.AudioClip中
不会从从继承的任何类扩展javax.sound.sampled.Clip中
,因此,它不具有 isRunning
法
要使用 javax.sound.sampled.Clip中
,你就必须利用的声音API ,对于<一个href=\"http://stackoverflow.com/questions/29836255/playing-multiple-sound-clips-using-clip-objects/29836764#29836764\">example和<一个href=\"http://stackoverflow.com/questions/17138614/clip-not-playing-any-sound/17139062#17139062\">example
本例中的音频剪辑预计将嵌入在JAR文件中(这个例子中有他们在声音
包,但你可以改变在任何你需要它)

基本上,玩的时候,这将动画的JLabel

In java i need to check if an audio clip is running but when i try something like:
if(clip1.isRunning()){
}
Eclipse gives me the error of:
"The method isRunning() is undefined for the type AudioClip."
Do i have to add something to use isRunning() on an audioclip? or am i doing something wrong?
Due to it being a long program here is just my imports and me initializing the audioclip and the part where i use it:
import java.applet.Applet;
import java.applet.AudioClip;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.Random;
import javax.sound.sampled.Clip;
import javax.swing.Timer;
AudioClip clip1;
public void mousePressed(MouseEvent me) {
if (xPos > 0 && xPos < 0+64 && yPos >0 &&
yPos < 0+64){
if(soundMuted == false){
soundMuted = true;
clip1.stop();
}
else{
if (clip1.isRunning()){
}
else{
soundMuted = false;
clip1.play();
}
}
}
}
And here is the error i get:
Description Resource Path Location Type
The method isRunning() is undefined for the type AudioClip HomeScreen.java
/AlexVega2/src line 421 Java Problem
java.applet.AudioClip
does not extend from any class which inherits from javax.sound.sampled.Clip
, therefore, it does not have a isRunning
method
To use javax.sound.sampled.Clip
, you'll have to make use of the Sound API, for example and example
The audio clip for this example is expected to be embedded within the Jar file (and this example has them in the sounds
package, but you can change to where ever you need it)

for (int index = 0; index < counter; index++) {

}
label.setText(sb.toString());
counter++;
if (counter > 10) {
counter = 0;
}
}
}
});
timer.setInitialDelay(0);
timer.start();
}
protected void play() {
try (InputStream is = getClass().getResourceAsStream("/sounds/Maid with the Flaxen Hair.wav")) {
try (AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(is)) {
clip = AudioSystem.getClip();
clip.addLineListener(new LineListener() {
@Override
public void update(LineEvent event) {

Basically, when playing, this will animate the JLabel
with a series if .
, when it's no longer playing it will just be a ___
blank line
