我正在开发一个IntelliJ插件,希望在后台任务中运行代码(在后台任务对话框中可以看到,在UI之外的线程中也可以看到)。
我找到了下面的Helper class,并通过传递一个Runnable对象并实现它的run方法来尝试它,但是它仍然阻塞UI,并且当我试图自己执行线程时,我得到了以下错误
Read access is allowed from event dispatch thread or inside read-action only (see com.intellij.openapi.application.Application.runReadAction())
Details: Current thread: Thread[Thread-69 [WriteAccessToken],6,Idea Thread Group] 532224832

我找到了一种更好的方法,可以将进程作为后台任务运行,您可以在其中更新进度条百分比和文本。
ProgressManager.getInstance().run(new Task.Backgroundable(project, "Title"){
public void run(@NotNull ProgressIndicator progressIndicator) {
// start your process
// Set the progress bar percentage and text
progressIndicator.setFraction(0.10);
progressIndicator.setText("90% to finish");
// 50% done
progressIndicator.setFraction(0.50);
progressIndicator.setText("50% to finish");
// Finished
progressIndicator.setFraction(1.0);
progressIndicator.setText("finished");
}});
如果您需要从另一个线程读取一些数据,则应该使用
AccessToken token = null;
try {
token = ApplicationManager.getApplication().acquireReadActionLock();
//do what you need
} finally {
token.finish();
}

以下是通用的解决方案
ApplicationManager.getApplication().executeOnPooledThread(new Runnable() {
public void run() {
ApplicationManager.getApplication().runReadAction(new Runnable() {
public void run() {
// do whatever you need to do
}
});
}
});

用kotlin运行后台任务的新方法
import com.intellij.openapi.progress.runBackgroundableTask
runBackgroundableTask("My Backgrund Task", project) {
for (i in 0..10 step 1) {
it.checkCanceled()
it.fraction = i / 10.0
sleep(i * 100L)
}
}
