要获取 Android WorkManager 中的 Worker ID,您可以使用 WorkInfo 对象中的 getId() 方法。以下是获取 Android Work ID 的示例代码:
```
WorkManager.getInstance().getWorkInfosByTag(tag).enqueue(new WorkManager.WorkerCallback<List<WorkInfo>>() {
@Override
public void onStopped(String workId) {
// Called when the worker is stopped
}
@Override
public void onStarted(String workId) {
// Called when the worker is started
}
@Override
public void onSucceeded(String workId, List<WorkInfo> workInfos) {
// Called when the worker is succeeded
if (workInfos != null && workInfos.size() > 0) {
WorkInfo workInfo = workInfos.get(0);
String workerId = workInfo.getId().toString();
// Use the workerId as needed
}
}
@Override
public void onFailed(String workId) {
// Called when the worker is failed
}
});
```
在上面的代码中,我们使用 WorkManager.getInstance().getWorkInfosByTag(tag) 方法来获取具有特定标记的 WorkInfo 对象列表。在 onSucceeded() 回调方法中,我们可以从 WorkInfo 对象中获取 Worker ID 并将其存储到字符串变量 workerId 中。
请注意,如果您没有将 Worker 添加到 WorkManager 队列中,则无法获取 Worker ID。因此,在获取 Worker ID 之前,请确保已将 Worker 添加到 WorkManager 队列中。
