Android PrintManager获取回调

我正在使用PrintManager打印网页，打印成功后，我的活动如何获得回调？ 我正在使用以下代码：

    // Get a PrintManager instance
    PrintManager printManager = (PrintManager) this.getSystemService(Context.PRINT_SERVICE);

    // Get a print adapter instance
    PrintDocumentAdapter printAdapter = webView.createPrintDocumentAdapter();

    // Create a print job with name and adapter instance
    String jobName = getString(R.string.app_name) + " Document";
    PrintJob printJob = printManager.print(jobName, printAdapter,
            new PrintAttributes.Builder().build());
    // Save the job object for later status checking
    //mPrintJobs.add(printJob);

围绕从webView接收的

PrintDocumentAdapter

创建包装。然后可以在onFinish（）中放置一个钩子

下面是如何在代码中使用它：

// Get a PrintManager instance
PrintManager printManager = (PrintManager)    this.getSystemService(Context.PRINT_SERVICE);

// Get a print adapter instance and wrap it in my own adapter
PrintDocumentAdapter printAdapter = new PrintDocumentAdapterWrapper(webView.createPrintDocumentAdapter());

// Create a print job with name and adapter instance
String jobName = getString(R.string.app_name) + " Document";
PrintJob printJob = printManager.print(jobName, printAdapter,
        new PrintAttributes.Builder().build());
// Save the job object for later status checking
//mPrintJobs.add(printJob);

我没有使用它，但它看起来像是在您的

打印适配器中完成的。是的，我在文档中看到了该方法，但是我如何实现它/覆盖它？创建一个类
扩展PrintDocumentAdapter
。然后，
@覆盖
必要的方法。基本上与活动、ArrayAdapter类和其他类一样。我只是浏览了一下，对该站点一无所知，但我们如何在onFinish方法中区分已保存->已完成和已取消？当您按print按钮
onFinish（）
调用时，我如何确定它是否成功？
// Get a PrintManager instance
PrintManager printManager = (PrintManager)    this.getSystemService(Context.PRINT_SERVICE);

// Get a print adapter instance and wrap it in my own adapter
PrintDocumentAdapter printAdapter = new PrintDocumentAdapterWrapper(webView.createPrintDocumentAdapter());

// Create a print job with name and adapter instance
String jobName = getString(R.string.app_name) + " Document";
PrintJob printJob = printManager.print(jobName, printAdapter,
        new PrintAttributes.Builder().build());
// Save the job object for later status checking
//mPrintJobs.add(printJob);
