标签的JavaFX打字机效果
问题描述：
我对这种方法有一些疑问.它工作正常，但有一个小问题.我称之为这种方法的时间太少了.因此只有最后一个字符串会打印在标签上.但我希望下一个字符串开始打印，仅在上一个字符串完成之后. 对不起，我的英语((
i have some problem with this method. it works fine, but with one little problem. there is too little time among i call this method. so only the last String is printed on a label. but i want that the next String starting printed, only after previous String is finished. Sorry for my English((
public void some(final String s) {
final Animation animation = new Transition() {
{
setCycleDuration(Duration.millis(2000));
}
protected void interpolate(double frac) {
final int length = s.length();
final int n = Math.round(length * (float) frac);
javafx.application.Platform.runLater(new Runnable() {
@Override
public void run() {
status.setValue(s.substring(0, n));
}
}
);
}
};
animation.play();
}
答
使用以下代码获得打字效果.
Use the following code to get a typewriting effect.
public void AnimateText(Label lbl, String descImp) {
String content = descImp;
final Animation animation = new Transition() {
{
setCycleDuration(Duration.millis(2000));
}
protected void interpolate(double frac) {
final int length = content.length();
final int n = Math.round(length * (float) frac);
lbl.setText(content.substring(0, n));
}
};
animation.play();
}
