我有一個Dialog類與它一wait方法來顯示我的自定義進度對話框：延遲顯示在JavaFX的節點運行Android
public static void wait(String title){
isOpen = true;
ProgressIndicator progress = new ProgressIndicator(-1);
Label label = new Label(title);
label.getStyleClass().add("login-label");
HBox container = new HBox();
container.setStyle("-fx-background-color: white;");
container.setAlignment(Pos.CENTER);
container.getChildren().addAll(progress,label);
if(Main.HEIGHT < 700){
container.setSpacing(10);
container.setPadding(new Insets(10,15,10,15));
}else if(Main.HEIGHT < 1200){
container.setSpacing(15);
container.setPadding(new Insets(15,20,15,20));
}else{
container.setSpacing(20);
container.setPadding(new Insets(20,30,20,30));
}
show("", container);
}
我有這一段代碼在我的類中的一個到dislay我陸侃對話框：
Platform.runLater(new Runnable(){
@Override
public void run() {
Dialog.wait("Processing, please wait...");
}
});
但遺憾的是其顯示一個延遲，我也試圖把它包裝在一個線程但它沒有工作，我試圖運行它在桌面和它的工作完美，但爲什麼不在我的Android設備？
下面是完整的代碼：
download = new Button("Download");
download.getStyleClass().add("terminal-button");
download.setPrefWidth(Main.HEIGHT > 700 ? 180 : 140);
download.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent event) {
Platform.runLater(new Runnable(){
@Override
public void run() {
Dialog.wait("Processing, please wait...");
}
});
Platform.runLater(new Runnable(){
@Override
public void run() {
//GET THE SELECTED AREAS FOR DOWNLOAD
List<String> selectedSectors = new ArrayList();
String sectorid = null;
for(Sector r : listView.getItems()){
if(r.isSelected()){
selectedSectors.add(r.getObjid());
sectorid = r.getObjid();
}
}
if(selectedSectors.size() > 1){
Dialog.hide();
Dialog.showAlert("Multiple downloads are not supported!");
return;
}
MobileDownloadService mobileSvc = new MobileDownloadService();
//INIT DOWNLOAD
Map params = new HashMap();
params.put("assigneeid", SystemPlatformFactory.getPlatform().getSystem().getUserID());
params.put("sectorid", sectorid);
batchid = mobileSvc.initForDownload(params);
int recordcount = -1;
while (true) {
int stat = mobileSvc.getBatchStatus(batchid);
if (stat < 0) {
try {
Thread.sleep(2000);
}catch(Throwable t){;}
} else {
recordcount = stat;
break;
}
}
if (recordcount <= 0) {
Dialog.hide();
Dialog.showError("No data to download");
return;
}
downloadsize = recordcount;
accountList = new ArrayList();
int start=0, limit=50;
while (start < recordcount) {
params = new HashMap();
params.put("batchid", batchid);
params.put("_start", start);
params.put("_limit", limit);
List<Map> list = mobileSvc.download(params);
//if (list != null) accountList.addAll(list);
System.out.println("fetch results is " + list.size());
//new Thread(new ProcessDownloadResultTask(start,list)).start();
start += limit;
}
Dialog.hide();
//SAVE AREA, STUBOUTS
clearSector();
for(Sector r : listView.getItems()){
if(r.isSelected()){
saveSector(r);
}
}
label.setVisible(true);
progressbar.setVisible(true);
progressbar.progressProperty().bind(task.progressProperty());
new Thread(task).start();
download.setText("Cancel");
download.setDisable(false);
download.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent event) {
continueDownload = false;
label.setVisible(false);
progressbar.setVisible(false);
download.setText("Back");
download.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent event) {
Main.ROOT.setCenter(new Home().getLayout());
}
});
root.setOnKeyReleased(new EventHandler<KeyEvent>(){
@Override
public void handle(KeyEvent event) {
if(event.getCode() == KeyCode.ESCAPE){
if(Dialog.isOpen){ Dialog.hide(); return; }
Main.ROOT.setCenter(new Home().getLayout());
}
}
});
Map params = new HashMap();
params.put("batchid", batchid);
params.put("downloadedlist", downloadedList);
MobileDownloadService svc = new MobileDownloadService();
svc.cancelDownload(params);
}
});
download.setDisable(false);
}
});
}
});
上述情況發生時，你單擊按鈕，輸出應該是：對話會馬上爲你按一下按鈕儘快彈出，但可悲的比方說，按鈕完成整個過程後，對話框會顯示！我試圖把它包裹在線程但沒有運氣！
請幫幫我！任何想法？
你的'Dialog'類從哪裏擴展？從內置的JavaFX對話框？從膠子的對話？或者它是一個免費的實現？ –
這是我自己定製的對話框，先生。 –
不錯，你有它的工作，但有時不需要重新發明輪子:)內置的'對話框（JavaFX或膠子的）都可以輕鬆定製。 –
